1. Limit high-fat foods: Strictly choose foods with low cholesterol content, such as vegetables, bean products, lean meat and jellyfish. In particular, eating more cellulose-rich vegetables can reduce the absorption of cholesterol in the intestine. However, we can't limit the intake of high fat unilaterally, because the intake of some essential fatty acids is beneficial to the body. It is reasonable to eat a diet containing more unsaturated fatty acids (controlling saturated fatty acids) in moderation. Various vegetable oils such as peanut oil, soybean oil and rapeseed oil are rich in polyunsaturated fatty acids, while animal oils such as lard, sheep oil and butter mainly contain saturated fatty acids. All the cholesterol in food comes from animal oils, such as egg yolk, animal viscera, fish eggs and brain. , which contains high cholesterol, should be avoided or used less. \x0d\2。 Change the cooking method: use less oil to cook, and try to steam, cook and cool the pot. Eat less fried food. \x0d\3。 Limit sweets: sugar can be converted into endogenous triglycerides in the liver, which increases the concentration of triglycerides in plasma, so the intake of sweets should be limited. \x0d\4。 Weight loss: For people who are overweight, they should gradually lose weight under the guidance of a doctor, and it is appropriate to lose 1 ~ 2kg per month. The diet principle of losing weight is low fat, low sugar and enough protein. \x0d\5。 Strengthen physical activity and physical exercise: Physical activity can not only increase the consumption of heat energy, but also enhance the metabolism of the body, improve the activity of some enzymes in the body, especially lipoprotein esterase, which is beneficial to the transportation and decomposition of triglycerides, thus reducing blood lipids. \x0d\6。 Quit smoking and drink less: moderate drinking can significantly increase serum high density lipoprotein and reduce serum low density lipoprotein level. Therefore, moderate drinking can reduce the prevalence of coronary heart disease. Excessive drinking or long-term drinking can stimulate the liver to synthesize more endogenous triglycerides, which will increase the concentration of low-density lipoprotein in the blood and cause hypercholesterolemia. Therefore, middle-aged people had better not drink alcohol. The incidence and mortality of coronary heart disease in smokers are 2 ~ 6 times that of non-smokers, and are directly proportional to the number of cigarettes smoked every day.
