The Effect of Dietary Sugar Consumption on Sweet Taste Perception

The purpose of the study is to determine how reducing the amount of simple sugars in the diet affects sweet taste perception. Healthy adult subjects will be assigned to either follow their usual diet, or to replace sugar calories with fats or starch. The investigators hypothesize that eating less sugar will: 1. cause foods and drinks with a given amount of sugar to taste sweeter 2. cause people to prefer lower levels of sugar in foods and drinks
