...it's Chocolate!!!

Researchers from Tufts University and Italy conducted a study on hypertension -- published in the Journal of the American Heart Association, which concluded that a daily dose of dark chocolate, or rather the rich bounty of Flavonoids found therein, can significantly reduce high blood-pressure. It also appears to be helpful in dropping the level of LDL [bad cholesterol] in the blood.

As with everything, "all things in moderation."
