What is cholesterol?

Cholesterol is also an important indicator of clinical biochemical examination. Under normal circumstances, the cholesterol synthesized in the liver and taken from food will be converted into steroid hormones or become a component of cell membranes, and the cholesterol concentration in the blood will remain constant. When the liver is seriously diseased, the cholesterol concentration will decrease. In patients with jaundice obstruction and nephrotic syndrome, the cholesterol concentration tends to increase.

Cholesterol has a wide range of physiological effects in the body, but when it is excessive, it will lead to hypercholesterolemia, which has an adverse effect on the body. Modern research has found that atherosclerosis, venous thrombosis and cholelithiasis are closely related to hypercholesterolemia. If it is simply high cholesterol, dietary adjustment is the best way. If it is accompanied by high blood pressure, it is best to monitor blood pressure. As long as it is confirmed by a doctor as high blood pressure, antihypertensive drugs are needed. Hypercholesterolemia is a very important cause of atherosclerosis, so please pay attention.

What foods are suitable for people with high cholesterol?

1. Apple

Because it is rich in pectin, cellulose and vitamin C, it has a very good lipid-lowering effect. If you eat two apples a day for a month, the low-density lipoprotein cholesterol (harmful to the cardiovascular system) in the blood of most people will decrease, while the high-density lipoprotein cholesterol level that is beneficial to the cardiovascular system will increase.

2. Carrots

Rich in calcium pectate, it reacts chemically with bile acid and is excreted from the stool. The body must use the cholesterol in the blood to produce bile acid, thereby lowering the cholesterol level in the blood.

3. Corn

It is rich in calcium, phosphorus, selenium, lecithin, vitamin E, etc., and has the effect of lowering serum cholesterol.

4. Oysters

It is rich in zinc and taurine, especially taurine which can promote the decomposition of cholesterol and help lower blood lipid levels.

5. Almonds

People with normal or slightly high cholesterol levels can replace low-nutrient-density foods in their diet with almonds to lower blood cholesterol and maintain heart health.

6. Kelp

It is rich in taurine, which can lower blood pressure and cholesterol in bile; it contains dietary fiber alginate, which can also inhibit the absorption of cholesterol and promote excretion.
