, "spontaneous" -- that is, unexplained -- behavior change ran reduce the observed differences between experimental and control groups in even carefully designed prospective studies. Enrolled in this 7-year trial were almost 13,000 men at high risk of heart attack, one-half of whom were given "special intervention" to help them stop smoking, reduce their blood pressure, and modify their diets to lower their serum cholesterol.

studied the effects of the saccharin warning label on sales of diet soft drinks.

Most studies of the effects of nutrition education on food intake way also not be directly relevant to the question at hand, since they involve measuring short-term changes in the behavior of specific captive populations exposed to a carefully organized series of lessons for a relatively short period.

Research on consumer education in relation to diet might well profit from a similar emphasis on success, since there is evidence that many people have, in fact, changed what they eat in a direction that most health professionals would consider potentially beneficial. The public is anxious to be given dietary guidelines to avoid cancer, but scientists are anxious not to make promises prematurely.

We need to collect data on a national basis about what people eat and how this varies in relation to such factors as geographical location, lifestyle, social affiliation, and other social factors as well as such convene tionally considered variables as ethnic and socioeconomic groups. The data should be collected in such a manner that they can also be analyzed for information about the history of an individual's lifetime food habits, including changes in those habits.
