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.
Color may be key to spotting foods that fight free radicals, said Roberta Anding, an American Dietetic Association spokeswoman and a nutritionist at Texas Children’s Hospital in Houston. Daily consumption of berries may have a significant and statistical outcome on inflammatory markers within the body. (Click to Article)
