As people’s living standards continue to improve, their diets and lifestyles have changed accordingly, resulting in new changes in the disease spectrum. In recent years, medical checkups, especially those of white-collar workers, have shown that the incidence of fatty liver, lobular hyperplasia and hyperlipidemia is rapidly increasing, and these three diseases are plaguing our white-collar workers. In order to keep people away from fatty liver as early as possible, how should we arrange our diet scientifically and reasonably in our daily life and develop a good lifestyle? As we all know, the liver is the largest digestive organ of the human body, and the processes of digestion, absorption, oxidation, transformation and secretion of fat are inseparable from the liver. The accumulation of fat in the liver will lead to the formation of fatty liver. Health surveys have shown that the incidence of fatty liver among people engaged in marketing and public relations activities is as high as 60% or more. At the same time, it was found that the higher the benefits, the higher the prevalence of fatty liver among employees of companies that enjoy buffets, and this is all due to the “addiction to mouth”. The number of obese people in our population has exceeded 70 million, and the number of obese people is growing at the level of doubling in five years. Obesity is the most common and definite risk factor for non-alcoholic fatty liver, with a prevalence of 50-75%. The accumulation of fat in the liver is often proportional to body weight, and the incidence of fatty liver is higher in highly obese people. Therefore, appropriate reduction of nutrient intake, especially fat intake, and effective weight control can often lead to improvement of fatty liver. Excess nutrient fatty liver is mainly seen in obese patients and patients recovering from diseases, but also in some normal people who exercise too little. I have often heard that over-nourished obese people are prone to fatty liver disease, but can C people or undernourished people also get fatty liver? Many people think that fatty liver is caused by over-nutrition, but this idea is not comprehensive. Westerners who get fatty liver are mainly obese people. In Eastern countries, thin people can also get fatty liver, which is related to the “frugality gene” in the body of Eastern people. In the era of food scarcity, the existence of the “thrifty gene” in the body helps the body to store energy for consumption when hungry, but in the era of reduced exercise and great abundance of food, the “thrifty gene” is still at work in the body, so that the gene has become the fatty liver, type 2 diabetes, coronary heart disease susceptible. The “frugality gene” is still at work in the body, making it a predisposing factor for fatty liver, type 2 diabetes and coronary heart disease. Inadequate nutrition can also cause fatty liver due to chronic malnutrition, which leads to the mobilization and decomposition of adipose tissue in the body and the rapid increase of fatty acids in the blood, resulting in the accumulation of fat in the liver, as well as the lack of certain proteins and vitamins. Some people suffer from chronic intestinal diseases, long-term anorexia, diet, partial diet, vegetarian diet, malabsorption syndrome and gastrointestinal bypass surgery, resulting in hypoproteinemia, lack of choline and amino acids, when fat mobilization increases and a large amount of fatty acids are released from adipose tissue into the liver, thus causing the accumulation of fat in the liver and the formation of fatty liver. In fact, excessive fat intake is not the only cause of fatty liver, but also alcohol consumption, lack of oxygen, poor nutrition (protein deficiency, starvation, diabetes, etc.) and hepatotoxic substances that reduce apolipoproteins, so that triglycerides can not be transported out of the liver in time, thus depositing in the liver, which can also form fatty liver. Do fatty liver patients need additional vitamin supplements? Vitamins cannot be synthesized in the body, or the amount synthesized is too small to meet the body’s needs, so they must be provided by food or medication. When you have a fatty liver, the absorption and metabolism of vitamins are reduced, which seriously affects the function of all body systems. Therefore, patients with fatty liver should pay attention to multivitamin supplementation through various channels, especially for vitamins that are easily deficient. the B vitamins (including vitamin B1, vitamin B2, vitamin B6, vitamin B12, niacin, pantothenic acid, folic acid, etc.) are closely related to the liver. Deficiency of B vitamins can lead to reduced cellular function and cause metabolic disorders. Increasing the concentration of B vitamins and vitamin C can protect the enzyme system in the liver, increase the resistance of liver cells and promote liver cell regeneration, and prevent liver steatosis. Various beans, fresh fruits and fresh vegetables are rich in vitamin B1 (thiamin); millet, soybeans, dry yeast, bean paste, green leafy vegetables, animal meat, milk, liver and poultry eggs contain more vitamin B2 (riboflavin); beans, fresh green vegetables, animal liver, kidney, meat and yeast contain more vitamin B6 and pantothenic acid and niacin. Vitamin C is most abundant in green leafy vegetables. Vitamin E is highest in vegetable oils, followed by higher levels in legumes, nuts and cereals. All green or yellow vegetables are high in carotenoids, which can be further converted into vitamin A. As people become more aware of self-care, more and more attention is being paid to the prevention and treatment of nutrition-related diseases, and education should be strengthened in community health work in the future. The aesthetics of contemporary society is “C for beauty”, many modern women like to go on a diet, it is said that improper weight loss can also lead to fatty liver? Nowadays, many young women, regardless of whether they are overweight, envy the slim figure, desperately pursuing “bony beauty”, deliberately eat little or no staple food, or even eat only fruit, vitamin tablets, etc., a direct consequence of this is malnutrition, protein, calories and other serious deficiencies. Protein is not enough, the fat-carrying apolipoprotein is also seriously inadequate, the metabolism of the liver is disturbed, liver cells are malnourished, fatty degeneration, there will be some fat bubbles in the liver cells, so that the liver enlarges and develops into fatty liver and even liver fibrosis and sclerosis. By over-restricting the diet, the body cannot get enough energy, and in order to make up for the lack of glucose in the body, it will mobilize the fat and protein stored in other parts of the body and convert them into energy. In the process of energy conversion, a large amount of fatty acids will enter the liver, leading to fat deposits. It is certainly good for overweight people to lose weight, but some people blindly pursue the speed of weight loss, do not pay attention to scientific weight loss methods, do not know that weight loss too fast to the liver damage is very big, so it is recommended that obese women should lose weight gradually under the guidance of a nutritionist. We have those foods in our daily diet can prevent fatty liver? It is advisable to eat more cucumber, radish, winter melon, yam, konjac, spinach, cabbage, sweet potato, asparagus, onion, garlic, bitter melon, pumpkin, carrot, cabbage, eggplant, lotus root, rhizome, tomato, water chestnut, wild rice, lettuce and other fresh vegetables are rich in vitamins, fiber, inorganic salts and trace elements, which can play a hunger, lower blood fat, lower blood sugar, weight loss and prevention of fatty liver; it is advisable to eat more mushrooms, straw mushrooms, shiitake mushrooms, flat mushrooms. Straw mushrooms, shiitake mushrooms, flat mushrooms and other mushroom food is high protein, low fat, rich in natural vitamin health food, has a unique health care effect, such as lowering blood lipids, lowering blood pressure, anti-virus, anti-tumor, so this type of food can help prevent fatty liver; should eat more soybeans, peas, black soybeans, mung beans and other beans and their products soy milk, tofu, soy flour, is a good source of human protein, which accounts for polyunsaturated fatty acids 60%, and rich in phospholipids, vitamins, trace elements and other beneficial ingredients; it is advisable to eat more kelp, eels, fish, oysters, pearls, clams, snails and other aquatic products can reduce serum triglycerides and cholesterol levels, and promote the elimination of fatty deposits in the liver; it is advisable to eat more sea fish, kelp, nori, can reduce blood lipids, inhibit platelet aggregation, thus contributing to the prevention and treatment of atherosclerosis, coronary heart disease and fatty liver. Staple foods should be combined with grains and cereals such as oats and corn, oats are rich in linoleic acid and rich in saponins, can reduce serum cholesterol, triglycerides. Corn is rich in calcium, selenium, lecithin and vitamin E, which have the effect of lowering serum cholesterol. In summary, the fatty liver patients friends in the diet nutrition should be a reasonable arrangement of diet, scientific weight loss. 1, carbohydrate intake to moderate: energy supply should not be too high, to maintain normal weight is appropriate. Carbohydrates are mainly provided by cereals and grains, reduce sugar and sweets, try not to use refined sugar, honey, sugary juices and drinks, fruit preserves, etc., to avoid eating too much carbohydrate and converted into fat. 2, control fat and cholesterol intake: no more than 40 grams of fat and no more than 300 mg of cholesterol throughout the day (an egg contains about 250 mg of cholesterol), for foods containing high cholesterol such as eggs The cholesterol content of foods such as eggs, animal offal, fish roe, squid, cuttlefish, etc. should be appropriately restricted. Cooking should be based on vegetable oils, preferably olive oil, olive oil is known as “green health care cooking oil”. 3, try to eat high-quality protein: can supply lean meat, fish, shrimp, skim milk, soybean products, etc.. The high protein diet can avoid protein loss in the body, which is conducive to the repair and regeneration of liver cells and prevent further damage to liver cells. 4, more vitamins, minerals and dietary fiber: adequate vitamins and minerals can ensure that the body is in the best condition, eat more fresh vegetables and fruits. Food fiber can reduce the absorption of energy and increase the feeling of satiety, block the hepatic and intestinal circulation of cholesterol and reduce its reabsorption.5. Special nutritional treatment for obese fatty liver patients: Overweight people should advocate weight loss, and progressive weight loss is the most effective. There are three concepts of weight loss, ineffective weight loss: less than 0.45 kg per month; effective weight loss: more than 1.2 kg per week; harmful weight loss: more than 1.5 kg per week and more than 5 kg per month. Patients who are overweight should strictly limit the intake of pure sugary foods. In addition, a low-salt diet should be maintained to reduce water retention in the body, and a daily supply of 1 to 2 g of salt is appropriate during weight loss. In general, the best way to prevent and control fatty liver is to adjust the diet, increase exercise and develop a healthy lifestyle. 4+1 diet is developed by Shanghai Nutrition Association according to the diet of Chinese people, which means 400 grams of rice and other staple foods, 300 grams of vegetables and fruits, 200 grams of dairy products, 100 grams of poultry and eggs, and a small amount of seasonings such as oil, salt, sauce and vinegar per day. However, for patients with severe fatty liver, especially those with abnormal liver function and steatohepatitis, drug therapy must be considered.
