Vitamin Supplementation

Currently, several large-scale intervention trials are underway to determine if B vitamin supplements (folic acid, B12, B6), which effectively lower blood homocysteine levels, reduce the incidence of vascular disease (Table 3). If proven effective, such supplements would be an inexpensive and relatively Table 3 Intervention trials to determine the effect of B vitamin supplements on homocysteine and the risk of vascular disease innocuous means by which the risk of vascular disease may be reduced. However, it must be recognized that if these trials are successful, they will not serve as definitive proof that homocysteine is a vascular toxin. It may be the case that one or more of the B vitamins influences vascular disease risk through separate mechanisms. For example, several studies have shown that low B6 status has an association with vascular disease independent of homo-cysteine. The uncertain relationship between hyperhomocysteinemia, B vitamins, and vascular disease is summarized...

Endotoxin Limits For Nutritional Supplements

Injectable forms of vitamins, trace minerals, and related nutritional supplements are increasing in importance for managing patients who require extended care. Simplistic test methods are needed to conveniently screen incoming nutritional agents. Table 4 contains test information for commonly administered vitamins. When a compendial EL was not available, the recommended daily dosage for an ingredient was used to calculate a limit. Since incoming materials are seldom in solution MVC was calculated to determine a range of test concentrations that would yield a sufficiently sensitive result with a kinetic BET.

Potential Benefits of Dietary Supplements

The 2000 Dietary Guidelines for Americans (new release due 2005) emphasizes choosing foods sensibly, maintaining a healthy weight, and exercising regularly. It acknowledges that some people may need a vitamin-mineral supplement to meet specific needs. Similarly, the Food and Nutrition Board and the American Dietetic Association also recognize that dietary supplements may be desirable for some nutrients and for some individuals. The following is a compilation of recommendations by these groups

Vitamins and Nutritional Supplements

Beginning in the 1940s, Henry Turkel, a Michigan physician, developed a theory based on the belief that individuals with Down syndrome experienced deficiencies of a variety of essential metabolic elements (Turkel and Nusbaum, 1985). Dr. Turkel proposed supplementing or countering these deficiencies with partially individualized formulations of vitamins, minerals, and medications. Called the U-Series, this formulation became the basis for many subsequent variations and the subject of a number of studies of its effects from 1950 through 1980. Schmid's concept of the genetotrophic basis for the challenges resulting from genetic conditions and the orthomolecular theory of Linus Pauling provided additional theoretical frameworks for nutritional supplementation in Down syndrome (Schmid, 1978). In 1981, a study of institutionalized adults with mental retardation by Ruth Harrell reported significant improvements in cognitive abilities after the administration of a U-series-like...

What Is a Dietary Supplement How Are They Regulated in Different Countries

Each country has developed regulatory definitions and systems that place dietary supplements, particularly botanicals, into categories of drugs, traditional medicines, or foods. However, in the late 1980s, many countries launched major changes in regulations that may or may not have been approved at the time of this writing. Many regulations are still in draft form. The US Congress defined the term 'dietary supplement' in the Dietary Supplement Health and Education Act (DSHEA) of 1994. A dietary supplement is a product, taken orally, that contains a 'dietary ingredient' that is intended to supplement the diet. The dietary ingredient includes vitamins, minerals, herbs or other botanicals, amino acids, a dietary substance for use by man to supplement the diet by increasing the total dietary intake (e.g., enzymes or tissues from organs or glands), or a concentrate, metabolite, constituent, or extract. Dietary supplements may be found in many forms, such as tablets, capsules, softgels,...

Compilations of Composition Data for Dietary Supplements

As the use of dietary supplements increases worldwide, there is an increasing need to quantify intakes of nutrients and botanical products from these sources. Compiling nutrient profiles of such products into tables can be very time-consuming because the number of products continues to grow and formulations of existing products often change over time. Furthermore, average analytic data are seldom available from the supplement manufacturers, and thus database compilers must rely on whatever information is available from the product label. In many countries, a label showing the amount of each nutrient in the product is required.

Dietary Supplementation for Active Individuals

The use of nutritional supplements in athletes and in the health-conscious recreationally active population is widespread, as it is in the general population. A very large number of surveys have been published. A meta-analysis of 51 published surveys involving 10 274 male and female athletes of varying levels of ability showed an overall prevalence of supplement use of 46 , but the prevalence varies widely in different sports, at different levels of age, performance etc., and in different cultural backgrounds.

Dietary Supplements

A dietary supplement is any product that is taken by mouth and intended to supplement the diet and is labeled as a dietary supplement. Dietary supplements may contain vitamins, minerals, herbs, and amino acids as well as substances such as enzymes, organ tissues, metabolites, extracts, or concentrates. The Dietary Supplement Health and Education Act (DSHEA) of 1994 established new guidelines for the safety requirements of dietary supplements and dietary ingredients of supplements. One requirement is that the dietary supplement contains only dietary ingredients which have been present in the food supply as an article used for food in a form in which the food has not been chemically altered. The alternative requirement is that there is a history of use or other evidence of safety establishing that the dietary ingredient when used under the conditions recommended or suggested in the labeling of the dietary supplement will reasonably be expected to be safe. As a result, dietary...

Occurrence of Low Intakes and Poor Biochemical Status in Present Day Societies

Other studies have shown that vitamin C absorption does not appear to be abnormally low in healthy older people. However, there is growing evidence that the multiple pathologies associated with old age (and with debility at any age) are associated with increased turnover of the vitamin. Older people with very low levels of vitamin C are at higher risk of dying sooner than those with high levels, although short-term vitamin supplements generally fail to reverse this increased risk. It thus appears that vitamin C status can act as a barometer of health as well as being a marker of adequacy of vitamin C intake. Further research is needed to determine the key mechanisms that affect the rate of vitamin C turnover and its control in different age

Digestion and Metabolism

In achlorhydric elderly persons the absorption of calcium carbonate from a dietary supplement after an overnight fast is very poor, presumably because calcium carbonate is a relatively insoluble calcium salt and needs gastric acid to be solubilized. Again, these subjects have normal calcium absorption if the calcium is delivered in a more soluble form, such as calcium citrate. In addition to elderly persons who develop achlorhydria, a large number of people regularly use gastric acid-lowering medications, such as the gastric proton pump inhibitor omeprazole, for antiulcer therapy. These medications can reduce zinc absorption and presumably may affect the absorption of other divalent minerals. Acidification of the gastric contents and solu-bilization of minerals in the gastric juice is important because many mineral nutrients are preferentially absorbed in the duodenum (upper small intestine) and need to be available in free or low-molecular-weight complexes when they leave the stomach...

Microbial Nutrition and Cultivation

Many microorganisms are unable to synthesise certain organic compounds necessary for growth and must therefore be provided with them in their growth medium. These are termed growth factors (Table 4.2), of which three main groups can be identified amino acids, purines and pyrimidines (required for nucleic acid synthesis) and vitamins. You will already have read about the first two of these groups in Chapter 2. Vitamins are complex organic compounds required in very small amounts for the cell's normal functioning. They are often either coenzymes or their precursors (see Chapter 6). Microorganisms vary greatly in their vitamin requirements. Many bacteria are completely self-sufficient, while protozoans, for example, generally need to be supplied with a wide range of these dietary supplements. A vitamin requirement may be absolute or partial an organism may be able, for example, to synthesise enough of a vitamin to survive, but grow more vigorously if an additional supply is made...

Adverse Effects of Non Oral Enteral Feeding

While placement of enteral feeding tubes is often taken for granted on a clinical hospital unit, complications are possible. These complications can be associated with placement itself, the mechanical effects of the tube once it has been placed, and the effects of the nutritional supplements themselves. Placement and mechanical complications, while unusual, include head and neck trauma (e.g., bleeding, infection, sinus perforation), inadvertent intubation of the tracheobronchial tree, esophagitis and esophageal stricture, and several issues related to dysfunction of these generally small caliber tubes. Many of these problems are not seen

Regulatory Activities

The development of more specialized enteral formulas for specific diseases has placed these formulas under increasingly intense secrutiny by the FDA. In 1988, the orphan drug amendment created a new category of food called medical food, which was defined as follows The term medical food means a food which is formulated to be consumed or administered enterally under the supervision of a physician and which is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements based on recognized scientific principles, are established by medical evaluation (112). Implicit in this definition is the notion that disease conditions can change an individual's nutritional requirements or food intake leading to a deficiency or overabundance of a nutrient. Although the amendment did issue the definition of a medical food under the current federal regulations that implement the Food, Drug, and Cosmetic Act, there is no procedural framework for...

Factors Affecting Cla Content Of Foods

A combination of dietary supply of PUFA and modification of the rumen environment can be especially effective to increase the CLA content of ruminant fat. Dietary supplements of fish oil and grazing pasture are two examples. Fresh pasture results in a two- to three-fold increase in the CLA content of milk fat, but the effect diminishes as the pasture matures. Increases in CLA observed with fish oils and feeding fresh pasture cannot be fully explained in terms of their PUFA content. Therefore, other factors or components of these feeds must affect rumen bacteria involved in biohydrogenation, thereby promoting rumen production of VA and CLA. Dietary supplements of CLA or VA can also be used to enhance the CLA content of ruminant fat. To be effective, these must be protected from rumen biohydrogenation, and dose-dependent increases in milk fat CLA content have been achieved.

Biological Effects Of

Trans-10, cis-12 CLA is a potent inhibitor of milk-fat synthesis in dairy cows (Table 2). This effect is specific for milk fat, and its mechanism involves coordinated reductions in mammary enzymes involved in milk fat synthesis. Effects of trans-10, cis-12 CLA are reversed when supplementation ceases, and the potential to use dietary supplements as a management tool in dairy production is being examined. The ability to selectively reduce milk fat yield could reduce energy demands during times when nutrient intake is inadequate, such as during environmental stress or in the transition period at parturition. 4 In dairy cows, certain dietary conditions also cause a reduction in milk fat, referred to as milk-fat depression (MFD). This is related to unique fatty acid intermediates formed during biohydrogenation, and rumen production of trans-10, cis-12 CLA and its metabolite trans-10 18 1 is increased during diet-induced MFD. Thus, MFD represents a natural situation in which fat synthesis...

Folate and Neural Tube Defects

And, most importantly, the incidence of NTD by about 20 over the first years of universal fortification. Because 30 of the population takes vitamin supplements and presumably would not be expected to derive significant benefit from fortification, the actual effect may be closer to a 30 decrease due to fortification. Recent calculations suggest that, for a variety of reasons, the overall fortification amount was about twice the mandatory amount.

Inappropriate Nutrient Forms and Expressions

Composition tables and also on nutrition labels for both foods and dietary supplements. A more relevant unit of activity, micrograms of retinol equivalents (REs), was adopted in 1967 and has been used to set recommended nutrient intake levels. A lower relative pro-vitamin A activity of carotenoids was assumed, and thus it is not possible to directly convert IUs into REs, unless both the retinol and the carotenoid levels of a food are given. Recently, the estimated pro-vitamin activity of carotenoids has been further reduced and a newer unit proposed micrograms of retinol activity equivalents (RAEs). Again, it is not possible to convert between REs and RAEs (or between IUs and RAEs), unless the retinol and carotenoid components of a food are available. Increasingly, food composition tables are carrying separate variables for the specific forms of nutrients such as vitamin A and iron, but this is not the case for many of the older tables. Such disaggrega-tion is an obvious advantage...

Concept and Definition

The concept of functional foods derives from the observation that certain foods and beverages exert beneficial effects on human health that are not explained by their nutritional content (i.e., macronu-trients, vitamins, and minerals). The definition of functional foods varies among countries for reasons that are historical, cultural, and regulatory. In its broadest use, functional foods are food-derived products that, in addition to their nutritional value, enhance normal physiological or cognitive functions or prevent the abnormal function that underlies disease. A hierarchy of restrictions narrows the definition. In most countries, a functional food must take the form of a food or beverage, not a medication, and should be consumed the way a conventional food or beverage is consumed. If the ingredients are incorporated into pills, sachets, or other dosage forms they are considered dietary supplements or nutraceuticals, not functional foods. In Japan and Australia, the functional...

European Regulations for Functional Foods

The concept of functional foods was first evaluated in Europe in the 1990s when the International Life Sciences Institute in Europe (ILSI Europe) developed a project on functional foods that became a European Commission (EC) concerted action, Functional Food Science in Europe. Approximately 100 experts in nutrition and medicine in Europe reviewed the scientific literature about foods and food components and their effects on body functions, and they developed a global framework that included a framework for the identification and development of functional foods and for the scientific substantiation of their health-related effects. From this evaluation, two types of claims for functional foods were suggested enhanced function claims and reduction of disease risk claims. From this evaluation, the ''Concepts of Functional Foods'' was produced by ILSI followed by publication of ''Scientific Concepts of Functional Foods in Europe Consensus Document.'' According to this concept document, ''a...

Crystalline Vitamins In Animal Nutrition

Only minor changes have occurred in vitamin production and use since 1978. 1 The fat-soluble vitamins used to fortify poultry and swine feeds include vitamins A, D, E, and K. Vitamin A, D, and E requirements are expressed as International Units (IU) per kilogram of diet. Poultry require Vitamin D3 because D2 is poorly utilized. 2 Vitamin K and the B vitamin requirements are expressed as an amount per kilogram of diet. Vitamins E and C and to a limited extent, vitamin A and p-carotene also function physiologically as antioxidants.1-3-5-1 precursor) for adult ruminants when some of the forage has been sun-cured to provide vitamin D2. 9'10 Also, healthy rumen microflorae synthesize all the B vitamins. Calves fed milk do not need vitamin supplementation, although milk replacers should be fortified with the required vitamins. 10 Ruminants fed high percentages of concentrate feed in intensive production, such as high-producing (lactating) dairy cows and feedlot cattle, may benefit from...

Vitamin Deficiencies

Other polymorphisms in MTHFR and other enzymes involved in homocysteine metabolism (e.g., methionine synthase, methionine synthase reductase (EC, cystathionine -synthase) have been identified and their overall influence on homocysteine metabolism, B vitamin requirements, and disease risk have been and continue to be evaluated.

Adequacy of Nutritional Therapy

Carefully executed diet therapy for individuals with PKU is widely considered to be safe as well as efficacious in preventing mental and neurological impairment. However, it cannot be assumed that largely synthetic diets supplemented with individual vitamins, minerals, and trace elements will confer the same benefits as diets composed of whole foods. Synthetic diets may have an inherent inability to supply all essential nutrients. In addition, patients who are noncompliant or partially compliant with their intake of medical food are at increased nutritional risk. Formerly treated patients who are 'off diet' tend to select high-carbohydrate diets and continue their habit of avoiding high-protein foods such as meat, milk, and eggs. Micronutrients previously supplied by the medical food, such as vitamin B12, zinc, and iron, may not be replaced in adequate amounts on such a self-selected diet.

Epidemiology and randomized controlled clinical trials

Epidemiologic studies have generally reported inverse associations between intake of various antioxidants and CHD risk. Most attention thus far has been directed to the study of naturally occurring antioxidants, particularly vitamin E, vitamin C, and beta-carotene, although other carotenoids, flavonoids, selenium, magnesium, and monounsaturated fatty acids are also found in natural food products and may reduce LDL oxidation. The major lipid soluble antioxidant vitamins are vitamin E (alpha-tocopherol), the predominant antioxidant present in plasma membranes, tissues, and LDL cholesterol, and beta-carotene, a precursor of vitamin A. The major water soluble antioxidant vitamin is vitamin C (ascorbic acid), which can regenerate alpha-tocopherol from the tocopheroxyl radical form, thus preserving lipophilic antioxidant within the LDL particles. In addition to foods rich in antioxidant vitamins, antioxidants are available as vitamin supplements, generally at doses much higher than those...

Type of Nutritional Support

Production (VCO2) is higher when carbohydrates are the main energy sources and lower when fat is mainly oxidised. However, patients with COPD who are in a stable clinical state usually appear to tolerate carbohydrates without difficulty. Respiratory failure has not been reported in studies of patients with COPD receiving nutritional support with enteral feeds and nutritional supplements containing up to 54 carbohydrate, but further work is needed to determine the optimal and safest feeding regimens for these patients.

Nutritional Support

Dietary supplements Although almost half of adult patients take dietary supplements, there are few published data to demonstrate their efficacy in CF. One study was unable to show any improvement in height and weight z scores when up to 30 of energy requirements were supplied by a supplement for 3 months. As a consequence, dietary supplements should be reserved for weight loss, any decline in height z score, if intake of a range of nutrients does not meet dietary reference values, or during acute chest infections. They should complement normal food intake and not replace food. In order to avoid reducing the intake of normal food, the recommended quantities are age dependent and are given in Table 3. Table 3 Recommended dosage of dietary supplements in cystic fibrosis Table 3 Recommended dosage of dietary supplements in cystic fibrosis

The present regulatory framework 1221 The US

As stated above, in the US functional foods are not recognized as a special legal entity, but are covered by the federal Food, Drug and Cosmetic Act. Other relevant legislation includes the Nutrition, Labeling and Education Act (1990) and the Dietary Supplement, Health and Education Act (1994), which basically define what kinds of claims can be attached to food products (Chadwick et al., 2003). The Food and Drug Administration (FDA) has a key role in assessing the evidence behind health claims, although other bodies of the US Government or the National Academy of Sciences can also provide authoritative statements on health effects associated with foods.

Application of Risk Assessment Methodology to Nutrients

Recent increases in demand for nutrients as a result of consumer interest in self-management of health, and provocative findings relating specific dietary constituents to possible health benefits, have provided incentives for industry to increase the availability and use of nutrients and food components in dietary supplements and for the voluntary fortification of foods. Thus, the need for science-based reviews of data on the potential for increased risk of serious adverse effects that may result from chronic consumption of individual nutrients in higher amounts than typically encountered with foods has grown in importance. Such reviews have been conducted by Canadian and US scientists through the Food and Nutrition Board, by the United Kingdom's Expert Group on Vitamins and Minerals, and by the Scientific Committee on Food of the European Commission, among others. Each has worked on developing approaches to evaluating reports of adverse effects and establishing, if possible, upper...

Target Nutrient Intake Possibly Achievable

The nutritionist discusses with the patient alternatives to dietary intake and the use of oral nutritional supplements that may include enteral diets taken by mouth. These supplements include liquid formula diets as well as specific supplements (e.g., potassium, magnesium, calcium, zinc, and vitamins). If during a trial period there is progressive improvement in intake or the patient meets the target, this process is continued. If the patient cannot meet the target or is clearly unable to progress toward it, then formal EN is started.

Toxins and Contaminants Phytic Acid

Because of its molecular structure, phytic acid is a highly effective chelator, which forms insoluble complexes with mineral cations. Its presence in plant foods has led to concerns that it may reduce the bioavailability of various dietary minerals and trace elements, including calcium, magnesium, iron,

Introduction and background

Extensive comparisons among LAB genomes are generating fundamental insights regarding aspects of microbial metabolism that may be important for strain selection in numerous dairy food applications. LAB appear to have many transporters at the cell surface that facilitate uptake and utilization of carbohydrates and proteins. The increased understanding of metabolic pathways may yield improved strain selection and food processing strategies. Knowledge of the genomic sequence has yielded bio-informatic strategies for prediction of nutrient requirements in L. plantarum (Teusink, 2005). The curated database for L. plantarum (http contained 129 pathways and 704 predicted reactions. The actual experimental results that tested amino acid and vitamin requirements agreed with results predicted from knowledge of functional genomics and pathways (Teusink, 2005). These results support the future importance of systems biology approaches that will effectively combine functional...

Commercial Applications

Certain flavonoids have long been used as drugs in Eastern European and Southeastern Asia. The pharmacological activities of these polyphenols have been less specific and less pronounced than those of alkaloids or steroids. Therefore, doubt and controversy have always surrounded the therapeutic value of polyphenols. Many European countries and Japan have been leaders in the commercial production of herb phytomedicinals consisting mainly of polyphenol compounds. Germany accounts for the largest share of the European Union herbal drug market, with sales of 3 billion of an annual 6 billion total (61). Of the 10 best-selling herbs in the United States today, echinacea, garlic, ginseng, ginkgo, saw palmetto, and eleuthero have been popularized. This is primarily the result of European research, which takes place under a more favorable regulatory climate that permits reasonable evidence of efficacy. In the United States, demand for excess amounts of evidence regarding efficacy has...

How Is the Sales Data Derived

Global sales have been estimated to be between 70 billion and 250 billion. This approximately 3-fold difference in estimates is due to the variation in what products are actually included in product sales results. As will be discussed, the definition of dietary supplements varies greatly from country to country therefore, deriving sales data is complex. Another difficulty in assessing sales of dietary supplements is the source from which sales data are gathered. Many business surveys rely on only one or two of the following sales outlets to derive their results

Prevalence of Micronutrient Supplement

In the United States, vitamins and minerals are the most widely used dietary supplements. Between 1993 and 2003, total retail sales of vitamins and minerals more than doubled, increasing from approximately 3 billion to 6.7 billion for vitamins and from approximately 0.6 billion to 1.8 billion for minerals. These figures include sales of multivitamin and multimineral combinations as well as individual vitamins and minerals. Multivitamin mineral preparations, accounting for almost half of micronutrient purchases, consistently have been the best-selling micronutrient supplements, with sales increasing from 2.64 billion in 1997 to 3.68 billion in 2003. Findings by several research groups show that micronutrient supplement use generally is more common among people with higher education levels, higher incomes, and better diets. Survey results in The Netherlands indicate that micronutrient supplements are used by approximately 20 of adults in that country, fewer than in the United States....

Research Approach for Determining the Health Impact of Micronutrient Supplements

Clinical trial, which is designed to eliminate all possible bias, is considered to be the gold standard of scientific intervention research. In such trials, some people receive the substance being tested (e.g., drug, micronutrient, or other dietary constituent) and some receive an inactive placebo. These trials may not be possible in all circumstances, however, because of ethical issues that make it inappropriate to withhold the substance being tested from any trial participants. For example, now that it is established that low periconceptual folate intake by women is linked to NTDs, a placebo-controlled intervention trial to test the minimum effective supplemental amount would be unethical. In such cases, all available evidence from in vitro laboratory research and in vivo animal studies, as well as epidemiologic studies and surveys, must be reviewed systematically and objectively to draw conclusions about the possible effectiveness and safety of the substance of interest and to make...

Nutritional Management of Tuberculosis Patients

The extent to which optimal nutrient intake improves the body's ability to heal during (and after) TB treatment is not well established. Fortunately, the immunological deficits associated with PEM and various micronutrient deficiencies are reversed rapidly with nutritional rehabilitation. One would expect this to improve recovery. The scientific literature is limited, however, with regard to the effect of nutrition on the outcomes of treatment. Only one randomized, double-blind trial is known, comparing vitamin A and zinc supplementation with placebo in 80 patients with pulmonary TB in Jakarta, Indonesia. BMI was

Vitamin E Status and Requirements

It has been suggested that the optimum concentration of a-tocopherol in plasma for protection against cardiovascular disease and cancer is 30 mmoll-1, given normal plasma lipid levels and in conjunction with a plasma vitamin C concentration 50 mmoll-1 and a -carotene level 0.4 mmoll-1. This has not been proven in large-scale human intervention trials, but even in the absence of conclusive evidence for a prophylactic effect of vitamin E on chronic disease prevention, some experts believe that a recommendation of a daily intake of 87-100 mg a-tocopherol is justifiable based on current evidence. Realistically, these levels can be achieved only by using nutritional supplements. The tolerable upper intake level for vitamin E is 1000 mg day-1, based on studies showing hemorrhagic toxicity in rats, in the absence of human dose-response data.

Emergency Department Treatment

ED management includes the history and physical examination, as reviewed. Adjuncts to care include use of vitamin supplements and food, dispensation of medications, updating of immunizations, and reviewing documentation of past medical care. Pregnancy status and potential for sexually transmitted diseases should be investigated in homeless women of childbearing age. Appropriate gynecologic care, prenatal care, or family planning services can thus be arranged. Once a diagnosis and treatment plan are defined, patients should be assessed for language barriers, literacy, and capacity to comply with routine care instructions, medical regimens, or follow-up. An old chart may indicate immunization status, forgotten or disregarded health problems, and the ability of homeless patients to follow up. A lower threshold for admission should be maintained for patients with an impaired ability to manage their own care. This decision is easily acceptable if one appreciates how the patient arrived at...

Causes of Altered DNA Methylation in Urological Cancers

Defects in methyl group metabolism could promote aberrant DNA methylation patterns by limiting S-adenosylmethionine supply, more precisely, by decreasing the ratio of S-adenosylmethionine to S-adenosylhomocysteine. This ratio depends on dietary supply with methyl-providing compounds and vitamins, specifically folic acid. The importance of methyl group metabolism is well-known from animals experiments, but only recently different lines of research have converged to provide evidence for its importance in man. Folic acid deficiency, which is surprisingly prevalent in industrialized countries, is reflected in a decreased intracellular SAM SAH ratio which in turn is linked to decreased methylcytosine in leukocytes.106 107 In tumor cells, this metabolic misbalance may be exacerbated by rapid proliferation and insufficient blood supply.108 Inadequate nutrition is known to synergize with low activity alleles of enzymes of methyl-group metabolism to cause cardiovascular disease.109 The best...

Modulation Of Alertness

Foods, such as warm milk, turkey, or bananas, facilitate sleep. Turkey and bananas have a known direct physiological effect They are good dietary sources of tryptophan, which is a precursor chemical for serotonin. Milk also contains tryptophan, but the quantities are lower The value of milk, particularly, warm milk, could well have more to do with stimulus-induced expectations (the warm milk might be a conditioned stimulus, associated with a bedtime routine). Nevertheless, although a banana at bedtime might improve sleep quality (which might perhaps impact alertness the following day), it is not obvious that a banana at breakfast would make a person less alert. Indeed, there is evidence that it might improve alertness. Dietary supplements of tryptophan are reported to be useful to reduce the symptoms of depression, including psychomotor retardation. Glucose is an important substance for neural functioning. Because there are no stores of glucose in the brain, availability in the blood...

An ingredient described in paragraph (ff) in, or intended for use in, a dietary supplement.'' Appropriate documentation must be maintained for ingredients subject to a GRAS notification. The proposed Dietary Supplement Good Manufacturing Practices (GMPs) regulations recently published by FDA outlines clearly the type of supporting information required to use a GRAS substance as a component in a dietary supplement product (Ref.(21), proposed section 111.35). A key section of this proposal related to components used in dietary supplement products states ''For those substances that are GRAS, proposed 111.35(d)(4) would require the manufacturer of the dietary supplement to have documentation for the basis for why such a substance, that is not a 'dietary ingredient' within the meaning of section 201(ff) of the act, is approved for use or is GRAS for use in a dietary ingredient or dietary supplement.'' The proposed regulation describes the specific types of documentation that are needed to...

Toxicants in foods and their effects on nutrition

Dibujos Depredador

Interest in developing ULs is partly in response to the growing interest in dietary supplements that contain large amounts of essential nutrients the other concern is the increased fortification of foods with nutrients. For example, for vitamin C and selenium, the UL refers to total intake from food, fortified food, and nutrient supplements, whereas for vitamin E it might refer only to intakes from supplements, pharmacological agents, or their combination. Often, ULs apply to nutrient intake from supplements because it would be extremely unusual to obtain such large quantities of a specific nutrient in food form.

Nutrient Requirements Omnivores Poultry and Swine

Microminerals (or trace minerals) that may be deficient in practical plant-based poultry and swine diets include zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), iodine (I), and selenium (Se). Phytate in plant ingredients may also reduce the digestibility of some natural microminerals. High quality salts of Zn, Fe, Cu, and Mn (sulfates, chlorides, or some carbonates, but not oxides), I (Ca or K iodate, Ca periodate, and ethylene diamine dihydriodide), and Se (Na selenite, Na selenate, or Se-enriched yeast) are usually added to the diet as a premix.'' Premixes may be custom formulated to meet trace mineral requirements that are not met by the base ingredients, and are added to the diet at a small, specified percentage. 4-9 Vitamins are organic compounds that are required in minute quantities for carbohydrate, fat, and protein metabolism and that function in some instances as coenzymes (catalysts).

The scientific and clinical rationale for probiotic and prebiotic interventions

The necessity to prove health benefits in appropriately designed and peer-reviewed human studies might seem an obvious milestone, but it represents a step not traditionally taken by companies selling food and dietary supplements (which is mostly the form used for probiotics). Low profit margins and an inability to make health claims have been cited as reasons for not doing clinical trials, but these can no longer be acceptable. This is not only necessary because of the growing interest in probiotic applications to medicine, but also because the expectation of consumers is that probiotics are not just foods, but they confer other health benefits. Companies are often quick to make wide sweeping health claims about their 'probiotic' products, yet too many are unwilling to invest in the research required to ensure that their products do in fact function as promised. The need for human studies is therefore ethical and responsible. In terms of what constitutes an appropriate level of...

Regulation of Functional Foods in the United States

Current US food regulations do not specifically address functional foods but, rather, include them in several categories within conventional foods, food additives, dietary supplements, medical foods, or foods for special dietary use. All of these fall under the amended Federal Food, Drug and Cosmetic Act (FDCA) of 1938 and are implemented under regulations from the Food and Drug Administration (FDA). Four types of claims can be used to communicate the usefulness of functional foods to consumers health claims, qualified health claims, structure-function claims, and nutrient content claims. Qualified health claims allow disease risk-reduction statements but, unlike health claims, must be qualified to indicate that the level of scientific support is not conclusive. Qualified health claims for dietary supplements were first authorized under a 1999 court decision in the case of Pearson versus Shalala regarding health claims for dietary supplements. In December 2002, the FDA announced the...

Nucleic acidbased techniques to type bifidobacteria 1751 Ribotyping

BOX-PCR was used to differentiate reference strains of bifidobacteria (Gomez Zavaglia et al., 2000). These patterns were then compared to those obtained from isolates obtained from fermented milk products to identify species, which correlated well with those obtained by whole cell protein SDS-PAGE. Using BOX-PCR for species identification, the majority of 58 food and dietary supplements evaluated were found to contain B. animalis ssp. lactis (Masco et al., 2005).

Food Intolerance and Allergy

Can be a successful treatment approach however, it is important that such diets be based on solid data from patients' history and skin tests and food challenge tests. Unfortunately, very few medical foods are available for those with food allergies. Infants allergic to cow's milk can be given soybean and hydrolyzed casein products, but for the many other types of food allergies, very few substitutes are available.

Dietary Selenium Absorption and Mechanisms of Incorporation of Selenium into Selenoproteins

Figure 1 summarizes the main pathways of interconversion of selenium in mammalian tissues. Selenium appears not to be an essential element for plants, but it is normally taken up readily into their tissues and is substituted in place of sulfur, forming the seleno-amino acids selenomethionine and selenocysteine, which are then incorporated at random in place of the corresponding sulfur amino acids into plant proteins. All branches of the animal kingdom handle selenium in essentially similar ways. When ingested, plant selenium-containing proteins liberate free seleno-methionine and selenocysteine, either for incorporation at random into animal proteins or for metabolic turnover, to liberate inorganic selenide, which is the precursor of active selenium to be inserted at the active site(s) of the selenoproteins. Selenide is also supplied by the reduction of selenite and selenate that enters the diet from nonorganic sources (i.e., from the environment) or from dietary supplements of...

Other Causes of Hyperhomocysteinemia

Other pathophysiological causes of hyperhomocys-teinemia include renal dysfunction and hypothyroid-ism. The kidney is a major site of homocysteine metabolism and renal disease leads to a significant reduction in the body's overall capacity to metabolize this amino acid. The resulting moderate to severe hyperhomocysteinemia can be attenuated, in part, by high-dose B vitamin supplements, which putatively maximize the residual renal metabolism, as well as the metabolic capacities of the extrarenal organs. Mild elevations in homocysteine occur in patients with hypothyroidism, which resolve to normal with thyroid replacement therapy. This observation implies that thyroxine and or thyroid-stimulating hormone influence homocysteine metabolism directly, perhaps through up- or downregulation of key homocysteine-metabolizing enzymes. Alternatively, homocysteine may become elevated in hypothyroid patients secondary to mild impairment of renal function that may accompany the disorder.

Health benefits of whole foods over isolated components

Recent surveys in Europe indicate that far more people are concerned about their food and their health than in the past. However, while consumers say they want to eat in a healthier manner, the reality is that they want to eat more easily, hence the claim of an enormous market potential for dietary supplements, nutrient enriched and functional foods, each of which contains perhaps one, or just a

Measuring Nutrient Bioavailability in Humans

A large and growing number of people are consuming dietary supplements. However, due to the relative difficulty of labeling these supplements, in most cases, little information on the bioavailability of the nutrients in the supplements is available. A study of vitamin and mineral bioavailability from a popular multinutrient supplement found good absorption of the water-soluble vitamins (B vitamins and vitamin C) from the tablet but relatively poor absorption of copper and zinc.

Colorectal Cancer Background and aetiology

In 1972, Burkitt described the relationship between diet and incidence of bowel cancer he hypothesised that a diet rich in fibre was associated with regular bulky stools and reduced bowel carcinogenesis, perhaps by reducing exposure of colonic mucosa to dietary carcinogens. It does seem likely that the combination of high fibre and low fat may be protective against bowel cancer. Protection against colorectal carcino-genesis is also derived from dietary supplements of calcium and folate and evidence from the Nurses Health Study (North America) suggested that oestrogen in the form of hormone replacement therapy (HRT) lowers the incidence of colorectal neoplasia. There has been interest in the potential influence of non-steroidal anti-inflammatory drugs in colorectal carcinogenesis. Cyclooxygenase (COX)-2 inhibition appears to have potent effects on the colonic mucosa, increasing apoptosis and reducing cellular proliferation. It is also likely that these drugs function through...

Helping the Public Get Accurate Science Based Information

Regulations applying to child-resistant packaging are governed by the CPSC. The Federal Trade Commission (FTC) enforces consumer protection laws that prevent fraud, deception and unfair business practices. They are responsible for truth-in-advertising for over-the-counter drugs and monitoring health benefit claims for foods and dietary supplements. The FTC is also responsible for reviewing proposed company mergers to assure there is no possibility of unfair business practices or anticompetitive activities that could harm the consumer. As part of the merger process, the product portfolio of marketed products and products in the development pipeline are examined by the FTC to determine if there could be a monopoly in a therapeutic or pharmacologic category of products. After evaluating the potential acquisition of Immunex by Amgen, Immunex was required to divest Leukine (sargramostim), which was purchased by Berlex , prior to FTC approval. Amgen already had two related hematopoietic...

Maternal Diet Altering Fetal Phenotype

Expression of the downstream agouti gene, which is involved in coat colour. The expression state of the cryptic promoter correlates with DNA methylation an active promoter is hypomethylated, while a silenced promoter is hypermethylated. An inbred population of mice carrying this epiallele display variable expressivity, with some mice having completely yellow coats and others a brown (agouti) coat. As well as the yellow and agouti coats, these isogenic mice can have various degrees of mottling, a trait that stems from variegation of agouti expression from clonally derived patches. Supplementation of maternal diets with methyl donors and cofactors involved in SAM production demonstrated that the proportion of coat colour phenotypes found in the offspring could be shifted from those on a control diet. With maternal micronutrient supplementation, an increased proportion of offspring were found to carry more heavily mottled coats. These effects were found to be influenced by the strain...

Bone mineral density

Osteopenia may be an accumulated result of lifelong diet treatment or poor diet compliance at vulnerable stages of bone development. Compliant patients tend to have low variation in their lifelong intake of whole protein, as controlled amounts of whole protein are required to maintain good metabolic control. Compliant patients tend to have similar trends in overall intakes. Lack of adequate trace elements, whole protein, vitamins, and or minerals may be culprits. Impaired absorption of the synthetic diet or the type of medical food used (hydro-lysate versus elemental formulation) may exert an independent effect. Inadequate intakes of calcium and phosphorous are known risk factors for the development of osteoporosis in nonaffected persons. Tailoring medical foods to specifically deliver the amounts of calcium and phosphorous recommended in the new RDIs may help to prevent osteopenia.

Vegetarian Eating Patterns

Numerous restrictions generally including avoidance of all meat, poultry, milk and eggs, but may consume fish in small amounts. Also avoid sugar and other refined sweeteners, foods that are members of the nightshade family (peppers, egg plant, tomatoes, and potatoes) and tropical fruits. Current variations of the diet are less restrictive than the versions of 30years ago, but deficiencies of energy, iron, calcium, vitamin B12, vitamin D, and other nutrients may still arise in weanlings, pregnant women, and young children if diets are nutritionally unplanned Avoidances include all animal products including meat, fish, poultry, eggs, and dairy products. Some vegans may also refuse to use any animal products in daily life. Without careful planning, energy, vitamins B12 and D, and bioavailable sources of iron may be low. Concentrated sources of energy-dense foods such as sugars and fats are helpful in increasing energy intakes. Vitamins B12 and D and calcium can be supplied from fortified...

Liver in Specific Hepatobiliary Disorders Hepatocellular Diseases

Table 1 summarizes the five published controlled trials of the effect of oral or enteral nutritional supplements on patients with alcoholic hepatitis. In most, nitrogen balance and or protein synthesis improved, although no effect on mortality was shown, perhaps because of the small number of patients studied and or the duration of follow-up. In the largest study, at 1-year follow-up, the experimental group had a significantly better survival 2 24 (8 ) died compared to 10 27 (37 ) of the controls. In general, the effects of parenteral nutrition in alcoholic liver disease are similar to those noted the studies of enteral nutritional supplements. Table 1 Studies on therapy of alcoholic hepatitis with oral or enteral nutritional supplements Table 1 Studies on therapy of alcoholic hepatitis with oral or enteral nutritional supplements

Clinical Features

Features of history are sometimes useful sexual behaviors, travel, volume and duration of alcohol use, illicit drug use, consumption of nutritional supplements (vitamin A), history of blood transfusions, needle-stick blood exposures, herbal remedies, mushroom ingestion, or raw oyster consumption. Family history may be revealing. Gilbert's syndrome is a relatively common and benign familial condition revealed by periodic modest elevations in unconjugated bilirubin, particularly in response to the stress of an acute illness. Family history of jaundice (elevated conjugated bilirubin) may indicate the presence of Dubin-Johnson or Rotor syndrome. Ihe differential diagnosis of familial severe premature liver disease includes Wilson's disease, hemochromatosis, or a -,-antitrypsin deficiency. Ihese uncommon disorders are mentioned because the emergency physician routinely sees and hence screens a large number of patients and is therefore more likely to encounter such diseases.

Dietary Guidelines for Health Function and Disease Prevention

Robert Russell and colleagues constructed a food guidelines pyramid, which specifically focused on the health of the elderly. Among the elements and tenets that differed from the standard US pyramid are the following recommendations to drink additional water and liquid to increase consumption of dietary fiber and to consider dietary supplements such as calcium and vitamin E. Otherwise, selecting the same requisite serving portions of the specific food groups, and avoiding excess sugar, salt, and separated fats as indicated by the conventional guidelines emblem is recommended for the older population as well.

Natural Ways to Become Pregnant

This natural approach to fertility has been very successful. It is particularly useful among women and men who have been diagnosed with unexplained fertility concerns. A British study conducted by the University of Surrey examined a group of couples with a prior history of infertility. These men and women made healthful changes in lifestyle and diet and took nutritional supplements and ended up achieving an 80 percent fertility success rate.

Dietary and Nutritional Management of Secondary Undernutrition

In juvenile cholestasis, large amounts of fat-soluble vitamin supplements and medium-chain triglycerides are usually required for optimum growth. With protracted secretory diarrheal diatheses, fluid and electrolyte balance may be the primary concern, followed by macro- and micronutrient nutriture, invoking the institution of parenteral feeding. Cancer cachexia is a major secondary consequence of disseminated neoplasms. It is tempting to prescribe aggressive nutritional support, but a caveat is that certain nutrients acting with certain neoplasms favor the tumor's growth and dissemination. To the extent that various forms of cachexia are partly driven by catabolic responses mediated by proinflammatory cytokines, antagonists directed at counteracting their action hold promise for retarding the nutrient-wasting in various forms of cachexia.

Potential Importance of Phytoestrogens to Human Health Molecular Mechanisms of Action

Some beneficial effects following dietary intervention with soy isoflavones have been observed on the cognitive function aspect of brain health, and the mechanism is likely to be via an oestrogenic action, particularly because ER , in addition to ERa, is expressed in brain. Although other mechanisms may contribute, they remain to be elucidated. Consumption by young healthy male and female subjects (parallel group design) of a high-soy diet (100 mg isoflavones day for 10 weeks) compared to a low-soy diet (0.5 mg isoflavones day) resulted in improved cognitive function, including significantly improved short-term and long-term memory and mental flexibility. These improvements were found in males and females. Consumption by post-menopausal women (parallel group design, placebo controlled) of a dietary supplement (soy extract containing 60 mg isoflavones day for 12 weeks) resulted in improved cognitive function, particularly improved long-term memory.

Treatment of Folate Deficiency

If the deficiency is nutritional it is usually treated in the first instance with dietary supplements. In the past, daily supplements of 5.0mgday_1 have been used but more recent evidence suggests that such high levels would only be appropriate for the immediate treatment of an overt deficiency. More long-term treatment would recommend dietary changes to improve folate intake. In practice, to achieve effective changes is very difficult so the recommendation might be to improve intake through foods fortified with the synthetic form of the vitamin, namely folic acid, or the use of supplements of folic acid. In both of these instances the aim is to achieve a maximum increased intake via folic acid of 400 mgday-1. Long-term ingestion of larger amounts are not recommended because of their ability to mask the diagnosis of vitamin B12 deficiencies (discussed above). Other causes of folate deficiency are treated by removing the cause, e.g., alcohol abuse.

PMS and Dietary Factors

High doses of vitamin B6 have been found to be effective in treating most of the most common symptoms of PMS in several double-blind, placebo-controlled trials. For this reason administration of dietary supplements is a popular therapy for PMS used by many medical practitioners. However, as large doses have been associated with dependency and sensory neuropathy, doses higher than 50 mg per day should be avoided. See also Appetite Psychobiological and Behavioral Aspects. Behavior. Brain and Nervous System. Carbohydrates Regulation of Metabolism. Cofactors Inorganic Organic. Hunger. Magnesium. Phytochemicals Epidemiological Factors.

The Potential Therapeutic Role of Vitamins

The potential therapeutic role of vitamins, such as vitamins D, K, B6, B12, and folate, has been investigated. However, additional studies are required to determine the role, if any, of such vitamins. It may be that some vitamins help protect against the side effects of tumor therapy, whereas some may modify tumor growth. Excessive dietary supplementation in cancer patients should be avoided until further evidence is available on the effects of vitamins on tumor growth.

Other Biological Hazards

Drug Administration (FDA) in efforts to prevent spread of the problem and to better protect public health. These measures included banning use of downer (unable to stand and walk) cattle from human food, holding carcasses of cattle tested for BSE until results are confirmed, prohibiting stunning of cattle with air-injection guns, banning from the food supply specified risk materials (brain, skull, eyes, spinal cord, small intestines, etc.) of cattle over 30 months of age and the small intestine of cattle of all ages, increasing process controls for material obtained with advanced meat recovery systems, banning use of mechanically separated meat in food products, and banning from FDA-regulated foods, dietary supplements, and cosmetics use of the previous materials.

Tocopherols and Cardiovascular Disease Epidemiological Evidence

87245 women, showed a 34 reduction in CHD in women who had consumed vitamin E supplements containing more than 67 mg a-TE daily for more than 2 years. However, there was no significant effect of vitamin E obtained from food sources. The Established Populations for Epidemiolodic Studies of the Elderly (EPESE) trials showed that the use of vitamin E supplements significantly decreased risks for all-cause-mortality and mortality from heart disease. Another prospective study, performed in Canada, reported a consistent inverse association between CVD and vitamin E supplement usage. The Health Professionals Study, conducted on 39 910 men aged 40-75 years, also showed that dietary intakes of vitamin E were not significantly correlated with reduced risk of CHD or death. A protective effect was seen in those who took 67-160 mg supplemental a-TE daily for more than 2 years. In contrast, the Iowa Women's Health Study reported that dietary vitamin E (mainly 7-tocopherol) was inversely associated...

Lifestyle intervention

With regard to dietary therapy, a review of 48 randomized controlled trials5 concluded that an average weight loss of 8 can be obtained over 3-12 months with a controlled energy low-calorie diet (LCD) aimed to reduce caloric intake by 500-1000 kcal day (2092-4184kJ day), and that this weight loss effects a decrease in abdominal fat. It also appears that lower-fat diets with energy reduction promote greater weight loss than energy reduction alone. Very low-calorie diets (VLCDs), generally involving the use of protein and dietary supplements, can produce greater initial weight losses that LCDs, but long-term ( 1 year) weight loss appears to be only marginally greater.80 Importantly, unless accompanied by physical activity, weight loss with dietary measures is not associated with an improvement in car-diorespiratory fitness as measured by maximum oxygen consumption.5,15

Equilibrium and Change

When human activities (e.g., farming or building roads) disrupt the ecological niches of other fauna, subsistence changes may bring increased food security but also increased disease prevalence. On the one hand, the massive development projects of the last century have contributed to sharp increases in the incidence of previously endemic diseases. On the other hand, public health promotion of childhood immunization, nutritional supplements, improved water systems, and disease prevention have led slowly to the epidemiological transition of the 20th century, with lowered infant mortality and longer average life expectancy.

Step 1 Asking an answerable structured question

Unless one uses such a structure, it would be easy to waste time discussing and searching for data on the role of diets in preventing atopic disease, the effects of dietary supplements such as fish oil, studies that evaluate only short-term clinical signs, and those that deal with a rag bag of different types of eczema in adults and children. Rzany discusses further examples of framing answerable questions in more detail in Chapter 5.

Introduction of Dietary Therapy

For regular infant formula or breast milk. In some clinics, only phenylalanine-free formula is given for a few days so that blood phenylalanine will quickly decrease to an acceptable level. A prescribed amount of breast milk or standard infant formula, however, should be shortly introduced into the diet. Whole protein is needed to meet phenylalanine requirements and prevent phenylalanine deficiency, which will lead to muscle protein catabolism and inadequate weight gain. For formula-fed infants, both standard infant formulas and PKU medical foods are used in prescribed amounts and are bottle fed. Breast-feeding of an infant with PKU is possible and, as with all infants, should be encouraged whenever possible. Mature breast milk contains approximately 46 mg 100ml-1of phenylalanine compared to approximately 59 mg 100 ml-1 in cows' milk protein-based formula and approximately 88 mg 100 ml-1 in soy-based formulas. Therefore, breast-fed infants may initially have slightly lower plasma...

Impact of Supplementation

Numerous investigators have explored the benefits of energy and or protein supplementation for pregnancy weight gain and other outcomes. However, relatively few trials have randomly assigned these supplements and used control diets. A statistical analysis was conducted of the 10 such studies that met this criterion in 1995. Most, but not all, of these studies were performed in developing countries. A 5-year controlled trial in The Gambia provided daily prenatal dietary supplements (two biscuits) that contained 4250 kJ energy and 22 g protein. This supplement increased pregnancy weight gain and birth weight during the hungry and harvest seasons. There was a significant but very small increase in head circumference and a significant reduction in perinatal mortality.

Historical Development And General

Phosphates exhibit functional properties in a wide variety of foods produced by all segments of the processed food industry. The availability of sodium, potassium, ammonium, calcium, and magnesium phosphates offers food technologists and food scientists formulation flexibility to control taste, nutritional, and other technical properties. The commercial use of food phosphates may be traced to 1864 when the first U.S. patent was granted for a phosphate-containing baking powder (1). The use of emulsifying salts in Europe for production of process cheese products began about 1895 and has been reviewed (2). Principal development in the United States began in 1916 (3). Since World War II new uses have developed in food products, including meats, poultry, seafood, beverages, dairy products, infant foods, cereals, desserts, produce, and nutritional supplements. Various detailed reviews have been published (4-6).

Free Radical Inhibitors Antioxidants

Treatments involve the oral administration of supplementary or excess doses of antioxidant vitamins and other substances believed to have antioxidant effects. The oral administration of cofactors for the action of antioxidants such as the minerals zinc and selenium is frequently included. Antioxidants and their cofactors have been included in nutritional supplements advocated for people with Down syndrome such as Nutravene-D. Risks. The risks of side effects or complications of this therapy are few. However, some vitamins, minerals, and other antioxidants can be given in quantities associated with overdose effects. As with other nutritional supplements, there is little regulation or quality control over the manufacture and marketing of products.

Current Vegetarian Eating Patterns and Practices

At the same time, vegetarian eating patterns are much more heterogeneous today than in the past. The availability and variety of plant foods, as well as commercially available and tasty meat analogs has greatly increased. Fortified foods today include soy milks fortified with vitamins B12 and D and a highly bioavailable form of calcium, and highly fortified breakfast cereals. These foods and nutrient-containing dietary supplements make it easier for vegans and vegetarians to obtain nutrients that would otherwise be low or lacking.


Without adequate supplementation can also result in many problems. An Angora doe will continue to produce fiber at close to an optimal level even when nutrition is inadequate. At such times, fiber production takes priority over maintenance of body weight or continuation of pregnancy. However, poor nutrition eventually results in production of short (but finer), matted mohair, lower fleece weights, lower reproduction rates, and abortion. An authoritative bulletin 3 contains energy, protein, mineral, and vitamin requirements of Angora goats for a wide range of body weights, different levels of activity, fiber production, growth, and milk production, and different stages of pregnancy. For year-round grazing on Texas rangeland, light, medium, and heavy stocking rates are considered to be one goat per 6.6, 3.3, and 2.2 acres, respectively.1-4-1 Supplementation of Angora goats (e.g., for development of kids, flushing of does, or inadequate forage on the range) and related economics are the...


Biological applications extend into uses for numerous pharmaceuticals, neutraceuticals, nutritional supplements, glandular extracts, and enzymes. Tissue implants, hormones, organs, glands, and tissue meats are considered to possess specific custom or health benefits. Other than heart, tongue, liver, kidney, pancreas thymus (sweetbread), brain, stomach (tripe), and intestines that are used as food, all other noncarcass material, though edible biologically, is generally referenced as by-product tissue.


Much has been referenced recently regarding various neutraceutical effects from a variety of foodstuffs that include those derived from animal by-products. A neutraceutical is vaguely defined. Though not defined as a specific required nutrient, the effects of identified compounds in specific tissues and their alleged benefit to certain health conditions is an expanding market. The majority of the neutraceuticals do not possess FDA approval for specific indications, but are marketed over-the-counter as nutritional supplements. Though the health food shelves are laden with products for nearly all ailments, an exemplary example of the product types are glucosamine hydrochloride and chondroitin sulfate. The supplements are labeled as an aid to the promotion of healthy cartilage and joint support. These supplements are extracts from animal by-product cartilage such as bovine trachea. There are numerous such supplements extracted or processed from animal by-products and made available for...


However, because of a law passed in 1994, the Dietary Supplement Health and Education Act, the Food and Drug Administration (FDA) is more limited in what it can do to regulate the safety, purity, and labeling of supplements than what it does for drugs or even foods. Supplement manufacturers are required to list the ingredients of their products but are not accountable for the validity of those lists. Supplements may contain more or less of the active ingredient than they claim or may contain various impurities. Moreover, manufacturers are not required to list possible side effects of supplements on labels or in promotional materials (see sidebar A Closer Look Supplements and the Law, this page). Finally, we don't yet know the active ingredient or ingredients in many herbal supplements and plant foods, so we have no way of knowing whether the commercially available extracts of those herbs or foods will have the same benefits as the foods themselves....

Specific vitamin requirements in burns patients have not been established, but levels may decline in the hypermetabolic state. As a minimum, the recommended daily allowance should be given following injury. For minor burns of 10-20 body surface area, supplementation with a single multivitamin tablet orally should replace vitamin losses sustained during injury. For larger burns, additional supplementation is advised, especially vitamin C (ascorbic acid), which is of benefit in wound healing and has experimentally been shown to possess free radical scavenging properties that may help to limit tissue damage. A recommended dose is 1 g daily in two divided doses for all patients with major burns children younger than age 3 years should receive half this dose daily. The essential, fat-soluble, vitamin A may also confer some advantages in wound healing and immunomodulation. A dose of 10 000IU daily is recommended for all patients with major burns who are older than the age of 3 years younger...

Concluding Remarks

Omega-3 fatty acids have long been recognized as beneficial foodstuff, but their actions are complex and thus poorly understood. There is now a resurgence of interest in omega-3 fatty acids, particularly DHA, among basic scientists and clinicians. DHA is being used in a variety of forms, from dietary supplements to novel drug conjugates, to benefit an extensive and varied series of conditions, including normal vision and neurologic development, heart disease, autoimmune disease, and cancer. The emerging literature suggests a diversity of mechanisms of action for DHA modulation of eicosanoid hormone production, generation of free radicals, regulation of gene expression, and the fundamental actions of DHA on membrane structure and function. It is the current state of the art, however, that the physiological and even cellular processes affected by DHA are not clearly connected to a single action of DHA, and thus there is urgent need for the interdisciplinary research that will link the...

Vitamin C

No single bacterial genus or species is known that will carry out all of the reactions needed to synthesize vitamin C, but there are two (Erwinia species and Corynebacterium genus) that, between them, can perform all but one of the required steps. In 1985 a gene from one of these genus (Corynebacterium) was introduced into the second organism (Erwinia herbicola), resulting in a new bacterial form. This engineered organism can be used to produce a precursor to vitamin C that is converted via one chemical reaction into this essential vitamin. The engineering of many other microorganisms is being used to replace complex chemical reactions. For example, amino acids, needed for dietary supplements, are produced on a large scale using genetically modified microorganisms, as are antibiotics.

Amino Acids

Amino acids have a great variety of current and potential uses as food, pharmaceuticals, and animal feed. Their main application field is food, where about 50 of the product is applied (4). They can be used as nutritional supplements, flavor enhancers, sweeteners, and in pre-and postoperative nutrition therapy (5). This section will discuss using ME to produce some of these amino acids. Recent progress in this field can be divided into three categories (6) (1) modification of central metabolic pathways, (2) modification of biosynthetic pathways, and (3) modification of transport systems. Figures 5.1, 5.2, and 5.3 summarize some of the examples discussed below.


In developing countries, cereal grains and some legumes are the primary and least expensive sources of calcium, iron, and zinc however, their intake does not satisfy the mineral requirements of the populations of these countries (Table 1.3) (Guzman-Maldonado et al., 2000). Numerous studies have led to the conclusion that phytic acid and tannins may bind proteins and some essential dietary minerals (calcium, iron, and zinc), thus making them unavailable or only partially available for absorption (Bliss, 1999 Guzman-Maldonado et al., 2000). Zinc is essential for normal growth, appetite, and the immune function, being an essential component of more than 100 enzymes involving digestion, metabolism, and wound healing (Bliss, 1999 Guzman-Maldonado et al., 2000). While iron deficiency has long been considered a major nutritional problem, zinc deficiency has only recently been recognized as a public health problem (Guzman-Maldonado et al., 2000).

Fish Minerals

Fish is a highly valuable source of most oligoele-ments. Fatty fish provides a notable contribution to iron supply, similar to that of meat, whereas shellfish have higher concentrations of most dietary minerals. In particular, crustaceans and bivalve molluscs supply zinc, manganese, and copper concentrations well above those of finfish. Worth mentioning is the extraordinary dietary supply of iodine in all kinds of finfish and shellfish however, this depends on the concentration present in feed, particularly in planktonic organisms. In summary, 100 g of fish affords low levels of sodium and medium-to-high levels of all the remaining dietary minerals. In fact, it can contribute 50-100 of the total daily requirements of magnesium, phosphorus, iron, copper, selenium, and iodine. A Mediterranean diet, rich in fatty fish and all kinds of shellfish, can lead to an overall balanced mineral supply, which may well reach over 20 of daily requirements of phosphorus, iron, selenium, and iodine....


Larkin et al. 11 noted low natural variation in hightannin tropical leguminous tree species. He further suggested that there would be a limited ability to alter tannin content through natural selection. He suggested that transgenics would be the best method of lowering tannin content in these species. Poppi et al. 12 suggested that proper grazing management and the use of nutritional supplements would be as effective as high-tech manipulation of lignin and carbohydrate content in tropical shrub species.

Diet And Nutrition

Supplementary minerals and vitamins can be supplied naturally as components of a mink's diet, or added in synthetic form. Minerals such as calcium and phosphorus, for example, can be derived either from bone-in products, such as whole fish, or by adding dicalcium phosphate to the feed. Most of the vitamin requirements, meanwhile, can be met by using so-called ''protective feeds.'' One of the most popular of these is liver, usually from beef cattle or chickens, and many farmers include liver in amounts of 5 or even 10 of the diet as a safety measure.


A strict PKU diet supplies 80-90 of its prescribed protein via a phenylalanine-free medical food. Most of the nitrogen in medical foods is supplied via essential amino acids. Meals that supply most of the protein as L-amino acids result in more rapid absorption and oxidation than observed after consumption of whole-protein meals. L-amino acids also may not be as efficiently absorbed as whole protein. Owing to these reasons, protein requirements for patients with PKU are considered to be greater than those given in the WHO guidelines and recommended daily intakes (RDIs). Normal growth and protein status has been observed in infants consuming at least 3 g protein kg-1 day-1. Long-term inadequate protein intake will result in impaired growth in infants and children, low plasma prealbumin concentrations, radiological bone changes (osteopenia), and reduced phenylala-nine tolerance. Because phenylalanine is an essential amino acid, it is crucial to prevent its deficiency. Phenylalanine...


The dietary supplements Asian ginseng (Panax ginseng) and North American ginseng (Panax quinquefolius) are widely used. The latter ginseng is more expensive. A HPLC-evaporative light scattering detection (ELSD) method was used for the identification of both ginsengs. Ginsenoside RF of Asian ginseng and 24 (R)-pseudoginsenoside F11 of North American ginseng can be identified at levels of 32-50 ng.47 HPLC-ELSD is a sensitive method for the identification of the origin of ginsengs. The same markers were used in the study of Chan T.W.D. et al. for the differentiation and authentification of Panax ginseng and Pananx quinquefolius.48 Ginsenosides are separated using HPLC with electrospray mass spectrometry detection. Identification is based on positiveion ionization of the characteristic molecular ions and thermal degradation products. The method is reliable and detection limit is in the nanogram range.


Vitamins and current discussion about their role in health have led them to believe in high vitamin consumption, sometimes 100 times the recommended dietary levels. Fortunately, no substantial increase of toxicity effects is associated with excessive vitamin ingestion. But toxicity can readily be induced from large concentrations of vitamin supplements or by the misuse of specific foods.


Acetylcholine is metabolized from choline and acetyl coenzyme A by choline acetyltransferase. Choline is available in food such as egg yolks, or by breakdown of phosphatidylcholine, more commonly known as lecithin, which is used as an emulsifier in foods such as chocolate. Choline is the rate-limiting step in the production of acetylcholine, such that insufficiency of choline in the diet can lead to deficits in acetylcholine, whereas dietary supplements can increase the production of acetylcholine. Acetylcholine is broken down in the synaptic cleft by acetylcholinesterase thus, acet-ylcholinesterase inhibitors, such as physostigmine or tetrahydroaminoaridine, have the effect of increasing the availability of acetylcholine in the synapse. There are two types of cholinergic receptors nicotinic (found in striated muscle and in the central nervous system) and muscarinic (found in smooth muscles and in the central nervous system).

Vitamin Addition

Use of SO2 may lead to additional reductions in levels of thiamine (13). Saccharomyces sp. has been shown to synthesize all required vitamins, with the exception of biotin. However, vitamin supplementation has been demonstrated to be stimulatory (17). Thus, it is usually desirable to add a mixed vitamin supplement with the nitrogen additions.


Grape tyrosinase is readily and rapidly inactivated by addition of SO2 to the juice must. However, sulfur dioxide addition also inactivates thiamine. If additions of more than 50 mg L SO2 occur, thiamine (in the form of nutritional supplements) should be added to the fermenter.

Folate Folic Acid

Comes from randomized controlled trials, notably the Medical Research Council (UK) trial on NTD recurrence and the Hungarian trial on NTD occurrence (i.e., first-time NTDs). These and other intervention studies are summarized in Table 1. Following earlier research, the Medical Research Council trial published in 1991 conclusively established the efficacy of folic acid in preventing NTD recurrence. This trial used a research design to investigate the effects of both folic acid and a combination of other vitamins. The recurrence rate in the groups that received folic acid (1.0 ) was significantly lower than that in the groups that did not take folic acid (3.5 ), giving a 71 protective effect. Thus, 29 of NTDs were not prevented by folic acid, at least not at the very high pharmacological dose of 4 mg daily used in the trial. The multivitamin combination without folic acid had no protective effect. The main observational studies that have examined the effect of periconceptional use of...

Other modalities

Probiotic agents, which are dietary supplements of living commensal micro-organisms of low or no pathogenicity, have been proposed as potential therapy for a number of clinical indications.62 A few small trials of therapy in adults with acute enteric infections have been reported, although the results appear conflicting.
