Why?Chocolate increases your body’s production of a powerful gas,which causes your blood vessels (血管)to relax and become wider.This,in turn,causes an increase in blood flow and a decrease in blood pressure—like opening a water tap.

I’ve been reading about the health benefits of chocolate for many years,but these studies really got my attention.Somehow,many people believe that if a food tastes good or if it makes you feel good,then it can’t possibly be good for you.Yet,an increasing number of studies show that some of the most delicious foods may also be among the most healthful.“Those were thought to be unhealthy,”a doctor said.“Precisely the opposite of what we now know to be true.” Title:Chocolate to Live for Chocolate improves blood flow to your heart,and 1.
