Step 2: bananas

Bananas are also common fruits. But its high medicinal value will always be ignored by people. Bananas are rich in norepinephrine, 5- hydroxytryptamine and dihydroxyphenylethylamine. Its main functions are clearing stomach, treating constipation, clearing away heat and moistening lung, quenching polydipsia, replenishing essence and relieving alcoholism. So bananas have the function of lowering cholesterol.

3. Hawthorn

Hawthorn contains triterpenoids, bioflavonoids and rich vitamin C, which has the functions of dilating blood vessel wall, lowering cholesterol and triglyceride and lowering blood pressure. In addition, it also contains maslinic acid and citric acid, both of which have significant hypolipidemic effects. However, some elderly people eat hawthorn, which will cause stomach discomfort such as acid regurgitation, and should be used with caution as appropriate. Hawthorn has the highest calcium content, which is beneficial to middle-aged and elderly people.

The correlation of three high lipids mainly includes cholesterol and triglyceride. There are two main sources of blood lipids, one is exogenous, that is, the lipid substances in our daily food are digested and absorbed and then enter the blood; The other is endogenous, synthesized by tissues such as liver and fat cells, and released into the blood during the normal metabolism of human body. Cholesterol can be synthesized in almost all tissues except brain tissue and mature red blood cells. The liver is the main place for cholesterol synthesis. In vivo, 70-80% of cholesterol is synthesized by the liver and 65,438+00% by the small intestine.

2. Hyperlipidemia and hypertension

There are many factors that affect the increase of blood pressure, among which peripheral vascular resistance, arterial wall elasticity and blood viscosity are important factors, and these three factors are directly related to hyperlipidemia.

The intima of normal people is smooth and flat, and the increase of blood lipid will gradually deposit yellow atherosclerotic plaque under the intima, which will rupture and bleed for a long time, narrow the lumen and increase the blood flow resistance, thus raising blood pressure; The increase of blood lipid and the deposition of blood lipid in the intima of artery can cause arteriosclerosis, weaken the elasticity of blood vessel wall and increase blood pressure. When the blood lipid rises, the blood viscosity increases, which increases the blood flow resistance, thus increasing the blood pressure.

3. The relationship between hyperlipidemia and hyperglycemia

Many diabetic patients are accompanied by hyperlipidemia, so people usually call diabetes and hyperlipidemia sister diseases, and think hyperlipidemia is the secondary disease of diabetes. According to statistics, about 40% of diabetic patients have lipid metabolism disorder. It is characterized by an increase in triglycerides and a decrease in high density lipoprotein. The reason why diabetes can cause blood lipids to rise is because when insulin is insufficient, the activity of lipase in the body decreases, so it is easy to raise blood lipids. On the other hand, diabetes itself is accompanied by disorder of fat, protein, water and dielectric besides disorder of sugar metabolism.
