Overview
Brief Summary
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:
- cause foods and drinks with a given amount of sugar to taste sweeter
- cause people to prefer lower levels of sugar in foods and drinks

Outcomes
Primary Outcomes
Change in Sweet Taste Intensity over Five Months
Time Frame: Monthly (for five months)
Subjects rated the sweetness of pudding and beverage samples that varied in sucrose concentration during each study month to determine how perception changes over time with diet manipulations
Change in Pleasantness Over Five Months
Time Frame: Monthly (five month participation duration total)
Subjects rated hedonic value (degree to which the sample was pleasant) for model pudding and beverages that differed in concentration of sucrose once each month over five months to determine how perception changed over time with the diet manipulation
Secondary Outcomes
- Sucrose detection thresholds(Every month (for five months))
- Body mass index(Every month (five months total))
- Diet records(Every month (five month total))
