Clinical Research -- What Should the Public Believe?

Abstract
Americans have become increasingly avid for news of clinical research that they feel will improve their health or extend their lives. This is particularly true of research about diet or lifestyle. To many Americans, as Fitzgerald points out elsewhere in this issue of the Journal, good health is largely a matter of living right1. They believe that they can ward off many if not most diseases and disability simply by knowing what foods to eat, what supplements to consume, and what leisure activities to pursue. This belief is fed by the new emphasis on preventive medicine as a solution . . .
