It is said in Neijing Zangfu Law: "Poison attacks evil, five grains nourish, five fruits help, five livestock benefit, five vegetables supplement, and the smell is combined to replenish essence." It is suggested that in addition to using drugs to eliminate evil, cereals, meat, fruits, vegetables and other foods must be used to replenish qi, nourish the body and enhance the disease resistance, so as to ensure good health.

Five grains include cereals and beans, five fruits include fruits, five livestock include livestock, and five grains include vegetables. Chinese medicine believes that these kinds of food should be eaten reasonably to be perfect.

"Five grains for nourishment" mainly means that cereals and beans are the basis of our people's health. Rice and wheat are the staple foods of our people, and 80% of the calories and 50% of the protein needed by the human body are supplied by cereals. Whole grain food is an important source of B vitamins and also provides some inorganic salts. Protein contained in beans is of high quality, and its amino acid composition basically meets human needs, among which lysine is more. Similar to cheese element, it has high nutritional value. Soybean contains unsaturated fatty acids, especially linolenic acid. The phospholipid content is about 1.64%. Generally speaking, cereals contain the most starch, followed by protein. The main supply of the body is sugar; Beans contain the most protein. Followed by fat, protein is the main supplier of the body. Although both grains and beans contain plant protein, their nutritional values are not exactly the same. Almost all amino acids lacking in cereal protein are lysine, while those lacking in legume protein are methionine. If you eat together often, you can compensate each other and improve the nutritional value.

In addition, beans and bean products can also provide dietary fiber and B vitamins. Vitamin e and zinc, molybdenum, selenium and other trace elements.

"Five animals are beneficial" is beneficial. Five animals are animal food with high nutritional value, which not only contains high energy, excellent protein, rich lipid substances, sufficient and balanced B vitamins and trace elements, but also tastes good. Strong satiety and high usability. Engels said that it is of great significance for human evolution, physical strength and intelligence, especially the development of intelligence to change from eating only plant food to eating both plant food and animal food. He said, "If we didn't eat meat, people wouldn't have developed to this point." At present. The average person in China only consumes 3,500 grams of meat every year, which can't meet the needs of the human body. According to the theory of traditional Chinese medicine, livestock and poultry meat food is called "flesh and blood". Its nourishing effect is indeed greater than that of vegetation.

According to Japanese medical reports, due to the lack of vitamin B 12, iron, protein and other nutrients and poor nutritional status, babies born to vegetarian mothers often suffer from brain damage to a certain extent.

Of course, as we all know, eating too much meat is not appropriate. Strong wine and fat will aggravate hyperlipidemia, hypertension and diabetes, and also promote rectal cancer and breast cancer. Therefore, eating meat in moderation is expensive. It is generally believed that the amount of meat is about one tenth of the amount of grain, and it is appropriate to eat 50 ~100g a day.

"Five dishes are stuffing", and "stuffing" means complementary and complete. Vegetables are an important source of several vitamins (vitamin A, vitamin D2, vitamin C, vitamin K, etc.). ) and inorganic salts (potassium, magnesium, calcium, iron, molybdenum, copper, manganese, etc. ) is also the source of cellulose, hemicellulose, pectin, lignin and some special enzymes, chlorophyll, pigment, aromatic volatile oil and so on. It is indispensable to the body. In terms of vegetable requirements, we should include fresh green, yellow and red vegetables, so that the nutrients will be more perfect. Crude dietary fiber is not digested by the secretion of human gastrointestinal tract, but it can promote the secretion of digestive juice and gastrointestinal peristalsis, help consumption and excretion, increase stool volume and improve stool habits.
