The role of nutrient intake in disease outcome is often examined in epidemiologic studies.
Most such studies conducted in the United States, however, have not included fortified foods or vitamin supplements.
In the United States, these are important sources of vitamins C and E, but not of bêta-carotene.
In addition, the importance of these nutrient sources varies by race, sex, and age.
Failure to include these sources produces errors in nutrient estimates, notable misclassification of individuals with regard to their total intake, and rankings of intake that bear little or no relationship to blood concentrations of those nutrients.
Implications for statistical analysis are also considered.
