Why are studies such as the Framingham Heart Study and the National Health and Nutrition Examination Survey (NHANES) important, and what have we learned from such studies?
The Framingham study was important as an epidemiologic investigation. In the 1940s we did not know enough about diet and heart disease to formulate hypotheses and do intervention studies. This study provided first convincing evidence that what a person eats is related to his/her risk for heart disease.
NHANES is a large ongoing epidemiologic study to simultaneously monitor nutrition and health in the U.S. population. Through NHANES we are learning more about many factors—especially nutrition—that are important for fostering good health and long life in the U.S. population.
