The Effect of Pecans on Biomarkers of Risk for Cardiovascular Disease and Diabetes
Completed · Not applicable
Conditions studied: Cardiovascular Disease Risk, Type 2 Diabetes Risk
In brief
The objective of this randomized, controlled feeding study is to investigate the potential health benefits of a pecan-containing diet. The investigators hypothesize the chronic consumption of pecans will improve an array of biomarkers related to cardiovascular disease and type 2 diabetes risk, including indices of oxidative stress, antioxidant activity, inflammation, endothelial function, and insulin resistance when compared with a control diet that is absent nuts.
