Eating bananas could prevent heart attacks and strokes－吃香蕉可預防心臟病及中風
New research reveals eating bananas every day could help prevent heart attacks and strokes. High in potassium, foods like bananas can stop fatal blockages from occurring and inhibit the hardening and narrowing of arteries.
Researchers at the University of Alabama analyzed mice who were at risk of heart disease. The mice were fed either low, normal or high levels of potassium with the results showing that the arteries of mice fed a low-potassium diet became significantly harder. In contrast, the mice given high potassium had less artery hardening.
The vital mineral － which spuds, broccoli and sprouts are also rich in － was found to aid blood flow to the heart and brain and reduce the risk of clots. Other foods rich in the mineral include parsnips, seeds, fish and poultry.
However, eating too much potassium can cause stomach ache, nausea and diarrhea. Older people may be more at risk because their kidneys may be less able to remove potassium from the blood.
