The main pathological changes of atherosclerosis are lipid deposition and atherosclerotic plaque on the intima of artery, and platelet aggregation leads to thrombosis, which makes the surface of intima of blood vessel not smooth and lumen narrow. Therefore, the diet should choose: (1) Eat more fish: Unsaturated fatty acids contained in fish oil (especially deep-sea cold-water fish) can resist platelet aggregation, reduce vasoconstriction, prevent oxygen free radicals from damaging cells, reduce blood lipids and increase high-density lipoprotein.

(2) Eat more garlic: Garlic contains antioxidants, which can prevent arteriosclerosis.

(3) Eat some nuts: walnuts, almonds, etc. It contains antioxidants, vitamin E and elemental selenium, which helps to protect the blood vessel wall. Eat nuts in moderation, not too much.

(4) Increase vegetables and fruits in the diet: it contains more vitamin C and carotene.

(5) Moderate drinking: Excessive drinking is harmful to people, which can increase blood pressure, relapse heart disease, aggravate arrhythmia and even cause sudden death. If you have drinking habits, keeping less than 2 glasses of red wine every day is beneficial to prevent arteriosclerosis. If you don't have the habit of drinking, you'd better keep the original habit.

Patients with arteriosclerosis should not eat too much animal fat and dairy products, nor should they drink too much.
