How does cholesterol rise? What should older people do to avoid high cholesterol?

1. Elevated cholesterol can be caused by genetic defects or secondary factors such as unhealthy lifestyles, liver and kidney disease. Genetic defects:Mutations in the relevant genes reduce LDL catabolism and increase the production of cholesterol ester-rich LDL, leading to elevated cholesterol. Unhealthy lifestyle:Such as high cholesterol diets, diets high in saturated fatty acids, and weight gain due to too little exercise can lead to an increase in cholesterol. Liver and kidney diseases:e.g. cirrhosis of the liver, viral hepatitis, nephrotic syndrome. can affect the catabolism of cholesterol, thus causing an increase in cholesterol. When cholesterol is elevated, you should actively go to the hospital for treatment, pay attention to diet in daily life, and exercise appropriately.

2. Eat more beans and products, weight can drop cholesterol. Beans contain lecithin, rich in vitamins and other minerals, especially suitable for brain workers. Soybean fat contains 85.5% unsaturated fatty acids, of which linolenic acid and linoleic acid are rich. They can reduce cholesterol in the body, especially conducive to the prevention and treatment of cardiovascular and cerebrovascular diseases in middle-aged and elderly brain workers. To reduce cholesterol, first pay attention to diet, choose a light diet, eat less fat and other animal fats, eat more vegetables and fruits. In addition to pay attention to exercise, try not to let the body obese, drink tea properly. If cholesterol is much higher, we can use drugs to reduce it. In short, reducing cholesterol is not achieved by solving the problem on one side. Need a variety of methods used together, need to adhere to long-term.

3. Control the intake of high cholesterol foods:Reducing the intake of high cholesterol foods is the most direct way to control and reduce cholesterol. For example, by controlling the intake of high cholesterol foods such as egg yolk, animal offal, fish roe, animal brain, shrimp, fatty meat, animal oil, cream or butter, shellfish, crab roe, etc., the level of cholesterol in the body can be rapidly reduced. Smoking cessation:Older people should stay away from unhealthy lifestyles in their daily lives, especially avoiding long-term alcohol consumption and smoking, which can reduce the damage of harmful substances to the liver, lungs and other internal organs. Once the liver and lung function is damaged, it will affect the body's metabolic ability, so it is very unfavorable to cholesterol reduction.
