Metabolism of Anthocyanins and Heart Health

This study aims to find out if consuming a single dose of blueberries, rich in anthocyanins, within an energy dense meal, improves blood vessel function and biomarkers of heart health. The study specifically aims to confirm if differences in how individuals process the bioactive compounds in blueberries, called anthocyanins, has an influence on heart health. The investigators will assess the effects of eating one portion of blueberries on vascular health over a 48hour period, and will track the breakdown compounds within blood and urine, to see if health effects are related to metabolism.
