The so-called reasonable diet includes two aspects: the first is that the dietary measures taken should not only achieve the purpose of lowering blood lipids, but also enable the patient to obtain sufficient nutrient supply in order to ensure good health. The one-sided approach of mainly vegetarian diet or “three no’s” (no meat, no eggs, no fish) is never desirable. The second is that dietary treatment should vary according to the type of hyperlipidemia, but also from person to person, not to be rigidly applied, not to mention the hearsay. The following is an introduction to the principles of dietary treatment for different types of hyperlipidemia: (1) Hypercholesterolemia The main point of dietary treatment for patients with only increased blood cholesterol and normal triglyceride content is to limit food cholesterol to a total intake of less than 200 mg per day. Patients should avoid or reduce the consumption of foods with high cholesterol, such as animal brains, spinal cords, offal, egg yolk (250-300mg of cholesterol per egg yolk), shellfish (such as mussels, snails, etc.) and mollusks (such as squid, cuttlefish and roe). On the other hand, patients should consume moderate amounts of nutrients that are not too high in cholesterol, such as lean pork, beef, duck, chicken, fish and milk. These foods are not high in cholesterol, for example, each bottle of milk contains only 30mg, and several other foods contain only about 100mg of cholesterol per 100g, so there is no need to overly avoid them, but of course, do not eat too much. The second is to limit animal fat and increase vegetable oil appropriately. Calculations show that if cooking without animal oil, each patient can eat vegetable oil (soybean oil, corn oil, vegetable oil, etc.) 500-750g per month is more ideal. Although vegetarian oil is good, but should not eat too much, otherwise it will also bring adverse effects. Third, eat more vegetables, fruits and vegetables to increase the intake of fiber. Fourth, eat more foods that have cholesterol-lowering effects, such as soybeans and their products, onions, garlic, goldenrod (grass head), shiitake mushrooms, fungus, etc. Some of these foods also have an anticoagulant effect, which is also good for the prevention of thrombosis and coronary heart disease. (2) Hypertriglyceridemia For patients who only have elevated blood triglyceride levels but normal cholesterol levels, the key points of dietary treatment are different from the above. The key is to restrict the amount of food eaten, reduce body weight, and achieve and maintain a weight in the standard range. The standard weight can be calculated by the following formula: Men: height (cm) – 105 (kg) Women: height (cm) – 107.5 (kg) The next point is to limit sweets. Such patients are particularly sensitive to sugar, and eating sugar can increase their triglyceride levels even more. Therefore, white sugar, brown sugar, fruit sugar, honey, and foods and drugs containing sugar should be eaten sparingly or not at all. Third, prohibit alcohol, which can increase the triglyceride content of such patients. Fourth, increase protein appropriately, especially soy protein. Fifth, appropriate cholesterol restriction, less than 300mg per day, allowing patients to eat 3 eggs per week, other cholesterol-containing foods can also be appropriate, as long as the total intake is not higher than the above threshold. Sixth, appropriately restrict fat, especially animal fat. (3) Mixed hyperlipidemia Patients with this type have elevated blood cholesterol and triglyceride levels, and the key point of dietary treatment is to combine the above two types. The main point of dietary treatment is to combine the above two types of hyperlipidemia, i.e. to limit cholesterol and animal fat, to control food intake to reduce body weight, to avoid eating sweets, to stop drinking alcohol, and to treat hyperlipidemia: (1) Hypercholesterolemia In patients with only elevated blood cholesterol and normal triglyceride levels, the main point of dietary treatment is to limit food cholesterol to less than 200 mg per day. spinal cord, offal, egg yolk (each egg yolk contains 250-300mg of cholesterol), shellfish (e.g. mussels, snails, etc.) and mollusks (e.g. squid, cuttlefish, roe, etc.). On the other hand patients should consume moderate amounts of nutrients that are not too high in cholesterol, such as lean pork, beef, duck, chicken, fish and dairy. These foods are not high in cholesterol, for example, each bottle of milk contains only 30mg, and several other foods contain only about 100mg of cholesterol per 100g, so there is no need to overly avoid them, but of course, do not eat too much.

(3) Mixed hyperlipidemia Patients with this type have elevated blood cholesterol and triglyceride levels, and the key point of dietary treatment is to combine the above two types. That is, appropriate restriction of cholesterol and animal fat, control of food consumption to reduce body weight, avoidance of sweets, abstinence from alcohol, appropriate increase of vegetable oils, beans and their products, and more vegetables, fruits and certain foods with lipid-lowering effects.
