During the 20th century, animal foods played an increasingly important role in the diets of Americans. As household incomes increase and families find themselves with more expendable income, consumption of animal products tends to increase in the United States as well as in other countries throughout the world. Generally speaking, proteins from animal products more closely match the amino acid requirements of humans than do plant-derived foods. Currently, foods of animal origin contribute a significant portion of daily calories to the typical American diet. Animal products supply about 60% of dietary protein and 40% of dietary fat. Also, many vitamins, especially water-soluble vitamins, are provided primarily by foods of animal origin. Animal products are the sole source of dietary cholesterol and provide about 70% of dietary saturated fatty acids.
