Dietary Lipids as Primary Modulators of Carotenoid Absorption in Vegetables

Not Applicable

Completed

• Conditions: Absorption of Carotenoids From Vegetables

• Registration Number: NCT01006174
• Lead Sponsor: Purdue University

Brief Summary

The purpose of this research study is to determine how dietary fats and oils influence the absorption of beneficial plant pigments (carotenoids) from vegetables. The study will examine changes in blood carotenoids in response to eating a salad with different fats/oils.
