(Newser) – Drinking green tea may help keep blood vessels elastic and healthy, a new study suggests. The flavonoids in green tea that work as antioxidants also produce the relaxing effect, which could also help prevent clots. Participants received the equivalent of three to four cups of the tea each day and showed even more improvement after a week of daily consumption, Time reports.

"Green-tea consumption may have beneficial effects on the arteries, but we should stop short of translating that into a recommendation that everybody should be drinking green tea because it's been proven to reduce heart attacks and strokes," says a past president of the American Heart Association.
