     On Tuesday,,a new study published in the American Heart Association's journal Circulation:Heart

Failure revealed that women who ate five or more dishes of baked fish had a thirty percent lower risk of

heart failure in comparison to women who ate less than one dish a month.

     Researchers examined the diets of 84,493 women,,whose ages ranged from 50 to 79.The women who had eaten lots of baked fish like salmon (鲑鱼),,were more healthy than those who mostly ate tuna (金枪鱼)or white fish.Eating baked fish also appeared to provide a protection against high blood pressure.The

study also found that those women who ate more baked fish were likely to have a lower weight,,exercise more and eat more fruits and vegetables in comparison to those who ate fried fish.

     Researchers noted that past research had discovered the fatty acids (脂肪酸)in fish probably

decreased the risk of high blood pressure by improving blood pressure along with heart and blood

functioning.This study showed the link between eating fish and heart failure risk but it was not designed to

show cause and effect.

     This study also showed that just by eating one dish of fried fish a week led to a 49% greater risk of

heart failure,,and eating fried fish led to lower fiber (纤维)intake and higher calorie (卡路里)intake.

     The American Heart Association suggested eating a minimum of two dishes of fish especailly fatty fish

each week.
