Summary

Overconsumption of carbohydrates has been implicated as a cause of significant public health problems including obesity and diabetes. The most effective approach to alter dietary pattern and improve public health is unknown. Gradual and abrupt changes in dietary pattern have been tried in small, uncontrolled trials, but it is not clear which approach is most effective. The primary objective of this study is to evaluate different approaches to changing dietary pattern for altering flavor perception in foods and beverages and for altering preference for flavor.

Detailed description

This comprehensive, well-controlled diet study aims to evaluate and compare different approaches to alter dietary pattern, especially macronutrient profile. The investigators propose a prospective, randomized trial that is designed to overcome the above limitations to test the hypothesis that changing dietary macronutrient profile can change taste perception and food preference. Data from this study will provide information that policy makers, regulators, and the food industry can use to develop successful approaches (gradual or otherwise) for providing healthy diets in the marketplace.
