1.Rational dietary structure: If diet therapy is used properly, most patients can expect to return to normal without the use of lipid-lowering drugs. Diet therapy is also through the reduction of total calories and increase physical activity to reduce weight. The diet for obesity and hyperlipidemia should be based on cereal staples, with carbohydrates accounting for more than 55% of total calories. Increase legumes, with an average daily intake of 30 g. The intake of animal protein should account for 20% of the total daily protein intake, and fat should not exceed 20% of the total calories. Fresh fruits and vegetables should be more than 400 grams/day, mainly dark or green vegetables, and the intake of refined rice and flour should be reduced to coarse grains. Fish contains polyvalent unsaturated fatty acids to prevent atherosclerosis. In addition, oats and black fungus have a more obvious lipid-lowering effect. Therefore, the daily available oats 50 grams, black fungus 5-10 grams, etc.. 2, hyperlipidemia contraindicated food: (1) avoid eating or eat less cholesterol foods: egg yolk, pig brain, pig liver, skin eggs, eel, crab yolk, pork loin, fish roe, cream, cod liver oil and other foods containing high cholesterol. (2) Avoid eating too much sweet food: too much carbohydrate such as sucrose, fructose, but serum cholesterol and triglyceride increase. (3) Avoid partial food: advocate a mixed diet to widely absorb vitamins and trace elements. Such as: green vegetables and meat in vitamin C, B6, B12, zinc pantothenate; beans, cereals and nuts in chromium, manganese; kelp in the iodine, garlic and onions have a very good role in lowering blood lipids and preventing atherosclerosis. (4) avoid eating more beef: over-eating beef can increase the content of serum cholesterol. (5) avoid drinking more coffee: too much coffee will increase serum cholesterol. 3, hyperlipidemia precautions: (1) avoid the number of meals: the longer the fasting time, the greater the possibility of fat accumulation in the body. (2) avoid dinner time too late: dinner time too late, eat original and indigestible food, will promote cholesterol deposition on the arterial wall, promote the occurrence of atherosclerosis. (3) Avoid excessive dinner: the basal metabolism of people in the evening is low, and food is easily digested and absorbed; at the same time, there is less activity and less energy consumption in the evening, and over-eating can be converted into fat. (4) Avoid not limiting the total calories: for an average adult, a daily calorie intake of 1200-1500 kcal is sufficient (more for manual laborers). (5) Do not blindly diet: long-term restriction of diet, the body lack of sugar, glucose into α-phosphoglycerol deficiency. Make the liver and fat in the alpha-phosphate glycerol decline, resulting in reduced triglyceride synthesis, the blood content is also reduced, a long time will cause serious malnutrition.
