Health news: 'Apple that takes years off your arteries' Rare, ancient breed of English apple could help boost heart health. Evesse apples are a rich source of polyphenols, which increase blood flow and relax the arteries. Just a tumbler full of Evesse juice is the equivalent of eating 30 of the red-fleshed apples, and makes the arteries ten years younger than their actual age. An ingredient made from the apples will be used as a liquid and powder supplement and added to food to help people maintain a healthy circulation. Studies by the Institute of Food Research in Norwich show that this ingredient, also known as Evesse, works on arterial stiffness within 30 minutes, with the relaxing effect lasting for up to eight hours. Evesse is at present available only in a fruit juice called RDA, on sale at Waitrose stores.
