生活百科：吃饭也防癌系列之五——如何通过饮食控制高血压

Never change your diet without first consulting your physician.

STEP 1 Eat less saturated fat 少吃饱和脂肪

Eat less saturated fat. If you are used to eating a diet high in fat, reducing your fat and cholesterol intake will reduce your blood pressure.

STEP 2 Keep your weight under control 控制好体重

Count calories and keep your weight in check. Putting on extra pounds tends to raise blood pressure.

STEP 3 Eat more produce 多吃农产品

Eat more produce. Fruits and vegetables contain potassium, a mineral that appears to lower blood pressure.

STEP 4 Reduce your salt intake 减少盐的摄入量

Reduce your salt intake if your blood pressure responds to salt in your diet. About 58 percent of people with high blood pressure are salt-sensitive.

If you are not sure whether you are salt-sensitive, consult your doctor about trying a low-salt diet to see if your pressure drops.

STEP 5 Drink in moderation 适度饮酒

Drink alcohol in moderation. Although studies have shown that one alcoholic drink a day can lower your blood pressure, drinking excessively will raise it.

Over the course of an average life span, the human heart beats about 2½ billion times without stopping.
