Eat Your Blueberries Men

Researchers from Wednesday's American Journal of Clinical Nutrition investigated the impact of blueberry flavonoid intake in healthy men and found that they acutely improve vascular function in a time-dependent manner. These benefits may be linked to the actions of circulating phenolic metabolites on neutrophil NADPH oxidase activity. The researchers assessed polyphenol absorption and metabolism at 1, 2, 4, and 6 hours after consumption of blueberry containing 766, 1278, and 1791 mg total blueberry polyphenols or a macronutrient- and micronutrient-matched control drink (0 mg total blueberry polyphenols). Significant increases were observed at 1–2 and 6 hours after consumption of blueberry polyphenols.
