16．A recent study has shown that eating a small amount of dark chocolate every day could be good for your health．Scientists have found that a regular 2ounces can help lower blood pressure and reduce the risk of having a heart attack or stroke（中风）without any weight gain．But take care before you reach for a large bar．The effects are canceled out if more than 30calories are taken into your body each day，the researchers warn．It's already known that a chemical called polyphenol（多酚），found in chocolate，can help reduce blood pressure，and blood pressure lowered in this way can reduce the risk of death from a stroke by 8percent and from a heart attack by 5percent，scientists declare．And it can also reduce the risk or death in general by 4percent．
A daily diet with a little chocolate has the same effect with some special diets designed to lower blood pressure，according to one researcher．"Although all the degree of the blood pressure reduction is small，the effects are quite obvious，"the researchers said．
However，Sara Stanner，a nutritionist at the British Heart Foundation，is quite cautious．"This study suggests that small quantities of small chocolate might have good effects on blood pressure．However，it is important to remember that chocolate is also high in fat and calories．So eating much is not good for your heart．""Polyphenols are also found in fruits and vegetables，which can be taken in without the risks associated with overintake，"she added．
But the German study shows that the fat content does not cancel out the good effects-at least where small amounts are concerned．
