A few cups of green tea each day may help prevent heart disease, Greek researchers found. Green tea improves both blood flow and the ability of arteries to relax.
When volunteers were given green tea, they experienced almost immediate benefits.
Other studies have shown that black tea also has benefits for cardiovascular health. However, green tea might be even better because it had higher quantities of beneficial compounds called flavonoids, some of which are lost in the oxidation process that black tea undergoes.
Flavonoids are also found in cocoa, tomatoes and grapes.
