Description

Summary

The main objectives of this study are to test the hypotheses that: 1) consumption of beverages sweetened with sucrose will increase risk factors for cardiovascular disease to a greater extent than a naturally-sweetened fruit juice such as orange juice, and 2) chronic psychological stress may augment the adverse metabolic effects of sugar intake. The study intervention consists of 2-week's consumption of 25% of energy as sugar provided either as a sucrose-sweetened beverage or naturally-sweetened orange juice.
