鱼的3重防护作用

Fatty fish guards your heart, brain, and circulatory system, new science shows:

Fixing Jiggy Heartbeats A 12-year Brigham and Women's Hospital study of 4,800 people found that those who ate any fish one to four times a week had a 28 percent lower risk of atrial fibrillation (AF) than those who avoided fish. AF disrupts your heart's rhythm, causing fatigue and shortness of breath.

Blocking Strokes Northwestern University scientists analyzed eight studies, involving 200,575 people, and concluded that eating fatty fish (such as salmon, mackerel, and herring) just once a week cut the risk of clot-caused strokes by 13 percent, though it had no effect on strokes from burst blood vessels.

 Disrupting Atherosclerosis A Harvard study of 727 women found that those who ate fatty fish almost every day--compared with those who ate it only three times a month--had 7 to 10 percent lower blood levels of molecules that bind heart plaque-building cells to artery walls.
