It is often assumed for the purpose of calculating vitamin E intakes from food in a-tocopherol equivalents (a-TEs) that 7-tocopherol can substitute for «-tocopherol with an efficiency of 10%. However, functionally 7-tocopherol is not equivalent to a-tocopherol and some caution should be used in applying a-TEs to estimates of a-tocopherol intakes when corn or soybean oils (hydrogenated vegetable oils) represent the major oils present in foods. These oils have high 7-tocopherol contents and if food tables reporting a-TEs are used to estimate dietary a-tocopherol, a-tocopherol intakes are overestimated. a-TEs are no longer recommended in the Food and Nutrition Board of the Institute of Medicine, National Academy of Sciences 2000 DRIs; only milligrams of a-tocopherol
