Cerebral arteriosclerosis is most often seen in people over the age of 50, more in men than in women, and in women after menopause. Cerebral atherosclerosis is often combined with aortic, coronary, renal and peripheral arterial sclerosis. Hypertension, hyperlipidemia, hyperglycemia, and hyperviscosity are important risk factors for cerebral atherosclerosis. Cerebral atherosclerosis is an important pathological basis for serious diseases such as vascular dementia, epilepsy, Parkinson’s syndrome, and cerebrovascular accidents including subarachnoid hemorrhage, transient ischemic attack (TIA), cerebral infarction, and cerebral hemorrhage. Therefore, the early prevention and treatment of cerebral arteriosclerosis is of great importance. Modern medical treatment for this disease generally takes mostly vasodilatation, lipid-lowering, anti-platelet aggregation, symptomatic drugs and dietary therapy, which have certain efficacy, but the effect of some drugs is still difficult to be sure. Therefore, people suffering from this disease, especially in the regular health care, with appropriate dietary adjustments can slow down the development of cerebral atherosclerosis. When the diet is high in animal fat and cholesterol, a large amount of lipids can be deposited in the walls of blood vessels, and accelerate the occurrence and development of atherosclerosis. Atherosclerosis patient’s diet should pay attention to the following points: 1, eat more vegetarian dishes and less alcohol: vegetarian dishes and fruits contain a lot of vitamin C, potassium and magnesium elements. Vitamin C can regulate cholesterol metabolism and prevent the development of atherosclerosis, while increasing the denseness of blood vessels. Alcohol, especially strong wine, can promote atherosclerosis, on the other hand, can induce a stroke. 2, commonly used vegetable oil less animal fat: vegetable oil contains unsaturated fatty acids, which can promote the reduction of serum cholesterol; while animal fat such as lard, cream, fatty meat, animal offal, egg yolk, etc. contain high cholesterol. 3, light diet but not full: diet to light is appropriate, because salty diet, sodium will enter the blood vessel wall, making it thicken and increase blood pressure. The amount of food should be appropriate, should not be too full, otherwise the body is too fat to increase the burden on the heart. 4, protein seafood can not be less: lack of protein in the diet, the same will occur vascular sclerosis. Protein contains animal protein and legume protein to supply the body with essential amino acids, drinking milk to remove fat is better. Seafood such as kelp, sea fish, etc. are rich in iodine, iron, calcium, selenium, protein and unsaturated fatty acids, recognized as brain nutrients, blood thinner, with the effect of lowering cholesterol and preventing atherosclerosis.
