Anthocyanins -- antioxidant pigments found in fruits and vegetables -- have well-established benefits for our cardiovascular system. The benefits are associated with their ability to influence the expression of chemicals by platelets in the blood, says new data from a randomized, double-blind, placebo-controlled trial.
The new study, published in Nutrition & Metabolism, deepens our understanding of the heart health benefits of anthocyanins, pigments found in many fruit like black raspberries, blueberries, blackberries, and blackcurrants. The water-soluble vacuolar pigments may appear red, purple, or blue depending on the pH. They belong to a parent class of molecules called flavonoids.
"These results are of public health importance because intakes of flavonoids associated with these findings are easily achievable in the habitual diet and make a significant contribution to the knowledge base needed to refine the current, rather general, fruit and vegetable dietary recommendations," wrote researchers from the University of East Anglia and King's College London.
