The Effect of Pecans on Biomarkers of Risk for Cardiovascular Disease and Diabetes: A Controlled Feeding Trial in Overweight/Obese Adults With Central Adiposity
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.
