The principles of diet and health Diet and health involves many contents, such as diet allocation, cooking and processing, eating hygiene, maintenance before and after eating, diet moderation, diet taboos and food therapy, etc. Some basic principles have been formed in the development of thousands of years, which is the valuable heritage of Chinese medicine. Reasonable allocation People eat a single food can not maintain the health of the body, because some essential nutrients, such as some essential fatty acids, amino acids and certain vitamins, can not be synthesized by other substances in the body, can only be obtained directly from food. In nature, there is no single food that contains all the nutrients required by the human body. Therefore, in order to maintain the health of the human body, it is necessary to consume different foods in combination. In addition, according to the theory of traditional Chinese medicine, attention should be paid to the compatibility of food. Food pairing is divided into two aspects: synergism and collapse. The synergistic aspect is divided into mutual necessity and mutual enablement, and in the fly down aspect is divided into opposite, mutual killing, mutual fear and mutual evil. This knowledge is also very important for our diet. The so-called phase shall, refers to the use of similar food with each other, can play a mutually reinforcing effect, such as lily stewed autumn pear, together with the effect of clearing lung heat, nourishing lung yin. The so-called make, refers to a type of food as the main, another type of food as a supplement, so that the main food to strengthen the efficacy, such as ginger sugar drink, warm and stomach of brown sugar, enhance the efficacy of warming and dispersing cold ginger. The so-called opposite, refers to the combination of two kinds of food, may produce adverse effects, such as persimmon avoid tea, white potatoes avoid eggs. The so-called phase kill, is that a food can reduce the adverse effects of another food. The so-called phase evil, refers to a food can reduce the effectiveness of another food. The so-called phase fear, refers to the adverse effects of a food can be reduced by another food, such as the adverse effects of lentils (can cause diarrhea, rash, etc.) can be reduced by ginger. The five flavors of harmony By five flavors, we mean sour, bitter, sweet, pungent and salty. These five types of food are not only important condiments for human diet, which can promote appetite and help digestion, but also indispensable nutrients for human body. According to Chinese medicine, different flavors have different effects. Such as sour taste has astringent sweat, stop sweat, stop diarrhea, astringent essence, constriction of urine and other effects, like umeboshi, hawthorn, shamrock, pomegranate, etc.; bitter taste has clearing heat, diarrhea, dry damp, lowering gas, detoxification, like orange peel, bitter almond, bitter melon, lily of the valley, etc.; sweet taste that is sweet, has a tonic, and soothing, antispasmodic and other effects, such as brown sugar, cinnamon meat, honey, rice and flour food, etc.; salty taste has a diarrhea, soft, loose knots and nourishing Yin and blood, etc. The role of salt, such as salt, kelp, seaweed, jellyfish, etc.; pungent flavor has a dispersing, moving Qi, blood and other effects, such as ginger, onion, garlic, chili, pepper, etc.. Therefore, in the selection of food, the five flavors must be harmonized, so as to be conducive to health, if the five flavors are too biased, will cause the occurrence of disease. The Yellow Emperor’s Classic of Internal Medicine has clearly pointed out: “careful and five flavors, bone and tendon soft, blood to flow, couples to dense, such as the bone to fine, careful way as the law, long have the life of heaven.” This means that proper harmony of the five tastes is an important condition for good health and longevity. To achieve the harmony of the five flavors, one should be the right strength and light. Second, we must pay attention to the combination of various flavors. Acid, bitter, sweet, pungent, salty complementary, with the right mix, the diet has a variety of different characteristics. Third, when eating, the taste should not be hyper, hyper too much, easy to hurt the five organs, not good for health. For the last point, “Yellow Emperor’s Classic of Internal Medicine” points out: “eat more salty, the pulse condensation bit and change color; eat more bitter, the skin is haggard and hair plucked; eat more pungent, the tendons are urgent and claws withered; eat more acid, it is inside the callus and lips uncovered; eat more sweet. Then bone pain and hair fall, this five flavors of injury.” That is, salty things to eat too much, will make the popular blood in the blood stagnation, and even change color; bitter things to eat too much, can make the skin withered, hair fall off; spicy food to eat too much, will cause the tendons and veins constricted, claws and nails dry not glorious; acid things to eat too much, will make the muscles lose luster, thicken and harden, and even the mouth and lips turned up; eat more sweet food, can make the bones pain, hair fall off. All of the above are cases where the health of the body is affected by the loss of harmony between the five tastes, which emphasizes the importance of harmony between the five tastes from the opposite side. The importance of eating healthy is illustrated by the proverbial “disease enters through the mouth”, and the outbreak of the hepatitis A pandemic in Shanghai in 1988, which is still fresh in people’s minds, is really shocking in terms of the extent of damage and harm. But some people do not take it seriously, “not dry, eat no disease,” the verbal phrase, will ring in people’s ears from time to time. In the vast rural areas, especially in remote places, this is a problem that requires great attention. Household tableware is often contaminated with a variety of bacteria, viruses, parasitic eggs, therefore, tableware to often clean poison. Before disinfection, the tableware should be washed, using hot water or alkali to remove grease and dirt, so that the disinfection effect is better. Commonly used disinfection methods are boiling disinfection, steam disinfection and bleach disinfection. The consumption of grease or grease-rich cakes, cookies, ham, sausages and other foods, in the storage process, due to the role of sunlight, metal containers and microorganisms, will produce a “harsh taste”, which is chemically known as grease rancidity. Oil and grease rancidity will not only cause food tasteless, reduce the nutritional value of the food itself, but also harmful to the human body, after eating will stimulate the mucous membrane of the digestive tract, making people nauseous, vomiting. Some people like to use newspapers to package food, but newspapers, magazines, books printed with ink words, ink contains polychlorinated biphenyls, is a very toxic substance. In addition, old newspapers, books are also covered with a large number of pathogenic bacteria, insect eggs and viruses, used to package food, but also contaminated food, affecting human health. Aflatoxin is currently recognized as a strong carcinogen in the world, long-term intake of food containing more aflatoxin, not only will occur acute and chronic poisoning, liver fiber degeneration, bleeding, necrosis, and can induce liver cancer. The fundamental measure to prevent aflatoxin contamination of food is to prevent mold, if you find peanuts, corn mold, should immediately pick clean. Family vegetable oil if contaminated by aflatoxin, the oil can be boiled, and then add some coarse salt frying pan, so that the detoxification of about 95%. If the rice is moldy, carefully scrubbed a few times, and then slightly add some alkali when steaming rice, can make aflatoxin greatly reduced. Peanuts, if mold is not serious, can be repeatedly scrubbed with water, and then fried with coarse salt, can also make the toxin reduced. Generally speaking, do not eat potatoes after sprouting, this is because potatoes contain lobotropin, which is an alkaloid harmful to humans. Once the potatoes are sprouted, the eyes and roots turn green, and the content of lobotropin rises sharply in the ulcerated area, which, if eaten, can produce nausea, vomiting, abdominal pain, diarrhea, and in severe cases, respiratory distress and coma. If the sprouting is not serious, the eyes of the sprout can be dug clean, and cut off the green part, and then put in cold water to soak for an hour, the toxic lobeliain will be dissolved in the water; cooking, and then add some vinegar, cooked braised rotten to remove the toxin. The diet has a section The Yellow Emperor’s Classic of Internal Medicine says: “diet has a section …… so can form with the gods, and the end of its natural life, degree 100 years is gone.” The Guanzi also says: “If you do not eat and drink with moderation ……, your body will benefit and you will live longer; if you do not eat and drink with moderation ……, your body will be tired and your life will be lost.” The “Thousand Gold Essentials” also says: “Too much food and drink will accumulate, too much thirst and drink will become phlegm.” These all illustrate the importance of diet to the human body. On the contrary, if you do not pay attention to the diet in moderation, how to eat what you want to eat, when you want to drink, when you drink, it will bring great harm to health. The so-called diet is moderate, means that the diet should be moderate, not arbitrary, to pay attention to the science and methods of eating. Specifically, we should pay attention to the amount of diet and eating time. First, the diet should be in the right amount. This means that people should not eat too much, and not too little, to be just right, hunger and full. The body’s digestion, absorption, transmission and storage of food mainly depend on the spleen and stomach to complete, if the diet is excessive, more than the normal amount of food transported by the spleen and stomach, it will produce many diseases. Tao Taoju, a famous Taoist figure and medical scientist in the Northern and Southern Dynasties, wrote this poem: “Why do we need to take big medicine for meals? But in the diet and appetite, the one who has gone very far will be happy.” “This poem advises the world that there is no need to pursue any immortality medicine, but to rely on those things to prolong life and live longer than a tortoise and a crane. As long as in the diet hobbies, change those most prominent fault, it will bring you peace and happiness. So, what are the “evens” in the food cravings? Overeating is one of them. Over-eating, suddenly eat a lot of food in a short period of time, is bound to increase the burden on the stomach and intestines, so that the food stays in the stomach and intestines, can not be digested in time, thus affecting the absorption and transmission of nutrients, the spleen and stomach function is also damaged due to overload. In fact, the ancients have long recognized this point. For example, the Yellow Emperor’s Classic of Internal Medicine says: “If you eat and drink too much, your intestines and stomach will be injured. The Museum of Science says: “the food more than, the heart more than stuffed, more than loss of years.” The “Donggu Huuyan” more clearly pointed out the specific hazards of eating too much: “People who eat too much have five problems: one is the number of stools, the second is the number of urine, the third is disturbed sleep, the fourth is heavy body is unable to cultivate, the fifth is suffering from food indigestion.” Too much food is not good for health, but too little food is also detrimental to health. Some people one-sidedly think that the less you eat the better, and as a result, forcing themselves to starve, because the body does not get enough nutrients, but weakness. The correct way is to “measure the abdomen by the suffer”, that is, according to their usual meal to decide how much to eat each meal. “Where the way to eat, no hunger and no satiety —- is said to be the program of the five organs”. This no hunger and no satiety, is the principle of eating the right amount of food. Only in this way, so as not to hurt the five organs because of hunger and satiety. Second, the diet should be regular. “From time to time, do not eat”, this is the eating habits of Confucius, that is, until it is time to eat, do not eat something, which is correct. Three meals a day, food sometimes, the spleen and stomach to adapt to this feeding pattern, when the time will be ready to digest food. People who like to eat snacks, when it is time to eat, often no hunger, barely stuffed with some food, but also do not feel any taste, and difficult to digest. The diet should be timed to this point, “Shangshu” has long pointed out that “food is but time”, meaning that people should eat each meal should be more fixed time. This is to ensure that digestion and absorption are carried out normally, and that the spleen and stomach can coordinate their activities, with openings and relaxations. “Chinese medicine believes that, in a day, the body of yin and yang have a change of strength and weakness, daytime Yang, activity, so the amount of food can be a little more; and the evening Yang decay Yin Sheng, that is, to sleep, to eat less appropriate. Therefore, the ancients have “breakfast good, lunch full, dinner less” the famous training. In the Qing Dynasty, Ma Qi’s “Land Immortal Scriptures” mentioned: “Breakfast is light and early, lunch is thick and full, dinner must be little, if you can always do so, no disease until old age”. According to the requirements of modern nutrition, the distribution ratio of the three meals a day should be 3:4:3, that is, if a day to eat 1 kg of food, breakfast and dinner each eat 3 two, noon eat 4 two, so more appropriate. It has been observed that eating 2,000 kcal at breakfast every day has no significant effect on body weight, while putting so many calories at dinner, a person’s weight will increase significantly. This shows that, for the impact of weight, “when to eat is more important than what to eat”. We emphasize “eating on time”, but also can not completely reject “eating on demand”, that is, eat a little when you want to eat, do not want to eat more, then eat less. Like people who work late at night, often do not want to eat at breakfast the next day, hoping to quickly sleep on a good sleep; moody people, often no appetite at mealtime; nap too long people, often do not want to eat at dinner time; are fully focused, busy with work or competition, naturally do not want to stop eating. For them, wait until they have an appetite to eat will be a little better. For this point, China’s famous health scientist Tao Hongjing has long pointed out: “not thirsty strong drink is stomach distension, not hungry strong food is spleen labor.” Meaning, if a person is not thirsty and forced to drink, it will make the stomach full, if not hungry and forced to eat, it will affect the digestion and absorption of the spleen, so that the spleen and stomach function is damaged. The above shows that “eating on demand” is a way of eating to adapt to changes in physiology, psychology and environment. However, it is not absolutely “at will”, snacking without leaving the mouth; nor is it randomly eating without any rules, but adapting to the changing environment outside, adapting to the changing needs inside, and making the eating activities more in line with the inner rules. In short, “eating on demand” and three meals a day, eating habits on time are complementary to each other, complementary to each other. They can be adapted to people’s dietary needs in different environments, and both aim to make people’s dietary activities more scientific and beneficial to health. Cooking is a good idea because reasonable cooking can make the food color, aroma and taste, not only to increase appetite, but also good for health. For example, when stir-frying vegetables should be quickly stir-fried, to avoid a long time stew, and to cover the pot to prevent the vitamin dissolved in water with the water vapor run away, but also to prevent the heating of the situation, the already easy to oxidize and destroy the vitamin C and then get sufficient oxygen supply and accelerate the oxidation and destruction. In stir-fry, a little vinegar should be added to both season and protect vitamin C less loss, this is because vitamin C is a reducing substance, more stable in acidic environment, but in neutral or alkaline environment, heating, it is easy to oxidize into diketogulonic acid and lose its role, adding vinegar can slow down this oxidation process. In a variety of cooking methods, to steam the least loss of nutrients, followed by fried, followed by frying, stir-fry. The most damaging to nutrients is boiling. Regardless of which method, it is best to achieve high heat and short time. In short, to master the cooking fire just right. In terms of staple foods, cook rice, porridge, beans, do not put alkali, because alkali tends to accelerate the destruction of vitamin C and vitamin B. Chinese nutrition also advocates that in the process of food preparation, attention should be paid to the reconciliation of yin and yang, hot and cold; for the elderly diet also advocates warm, cooked and soft, against the sticky, hard, raw and cold. The so-called reconciliation of yin and yang in the production, refers to the Yang food, you need to add green vegetables, green bamboo shoots, cabbage root, young rutabaga, fresh fruit juice and a variety of melon sweet moist products, so as to neutralize or soften the warm Yang food pungent too dry; and in the Yin food to add pepper, pepper, fennel, dry ginger, cinnamon and other pungent seasonings, can be reconciled or restrain the Yin nourishing products nourishing too greasy bias. The so-called production of the reconciliation of hot and cold, refers to the cold side of the body, cooking, it is appropriate to add more ginger, pepper, onion, garlic and other seasoning; hot side of the body, should be less seasoned with pungent and dry items, and must pay attention to the production of light, cold food, such as vegetables, fruits, melons. The elderly should pay more attention when cooking because of the weakness of the spleen and stomach. The “New Book for the Elderly” says: “The food of the elderly should be warm, cooked and soft, not sticky, hard and cold”. Therefore, cooking rice, as well as making fish, meat, melon, vegetables and so on, must be cooked and rotten side food. It should also be noted that meals should be light rather than salty, which is also a principle to pay attention to in cooking. Salt is an indispensable necessity in our lives, its role in the human body is to season, the second is to provide the body with sodium and chloride to maintain normal physiological metabolic functions. But salt can not eat more, many surveys show that eating too much salt, hypertension, coronary heart disease, cerebral hemorrhage and even cancer incidence are significantly higher. In general, the maximum amount of salt per person per day from food should not exceed 10 grams. However, there are special times, such as the summer season, when people sweat a lot and lose too much salt in their bodies, they should always pay attention to replenish the lost salt. The four seasons should be contraindicated “Drinking food is about to say:” spring temperature, it is appropriate to eat wheat to cool; summer heat, it is appropriate to eat peas to cold; autumn dry, it is appropriate to eat hemp to moisten its dry; winter cold, it is appropriate to eat millet to heat to cure its cold. This passage illustrates that, because the four climatic changes have a great impact on the physiology and pathology of the human body, people should choose different diets in different seasons. In the “Zhouli Tianguan”, it is also said that “in spring, it is appropriate to eat acid to astringent, in summer, it is appropriate to eat bitter to hard, in autumn, it is appropriate to eat pungent to dispersing, in winter, it is appropriate to eat salty to and soft.” This kind of time to choose the taste of the advocate is still popular with the masses. In the spring, everything revives, Yang Qi rises, and the Yang Qi of the human body also rises, at this time should be nourished Yang, in the diet to choose some food that can help Yang, such as onion, coriander, black bean, etc., so that the internal heat gathered in winter emanates. In the diet varieties, should also be changed from the winter creamy and thick taste to clear and warm bland. The general variety of vegetables in winter is less, the human body is often insufficient vitamin intake, therefore, in the spring dietary deployment, should be more fresh vegetables, such as winter green vegetables spring bamboo shoots, spinach, celery, swiss chard, etc.; in animal food, should eat less fatty meat and other high-fat food. Chinese medicine also advocates: “when the spring, food taste should be reduced acid benefit sweet, to nourish the spleen, drinking wine should not be too much, rice flour dough cake should not eat more, resulting in injury to the spleen and stomach, difficult to digest.” These are worth our attention. In summer, when it is hot and rainy, summer heat and dampness tend to take advantage of the deficiency, people tend to have a reduced appetite and weakened digestion, and most people are averse to fatty and greasy foods. Therefore, in the dietary arrangement, we should pay attention to the color, aroma and taste of food, and try our best to arouse the appetite so that the body can get a comprehensive and sufficient nutrition. According to Chinese medicine, in summer, Yang Qi is strong and Yin Qi is weak, so it is advisable to eat less pungent and sweet dry food to avoid excessive harm to Yin, and to eat more sweet and sour moist products, such as mung beans, watermelon and umeboshi. The “Yi body set” pointed out: “summer heart and kidney failure, although the great heat should not eat cold Amoy ice and snow, dense ice, cold powder, cold porridge”, otherwise drinking cold will make the abdomen cold, resulting in abdominal pain, vomiting, under the profit and other gastrointestinal disorders, this is especially important for the elderly and frail people, in addition, summer food is very easy to spoil, therefore, summer must pay attention to Food hygiene, do not drink raw water, raw fruits and vegetables must be washed. In autumn, the temperature is cool, dry, with the summer heat receding, people from the summer heat of sleepy, appetite gradually increased, plus a variety of melons and fruits on the market in large quantities, should pay special attention to “autumn melon bad belly”. After the autumn, whether it is watermelon or melon, vegetable melon, can not be wantonly eaten more, otherwise it will damage the spleen and stomach of Yang Qi. Because of the dry climate, in the diet, we should pay attention to less dry food, such as chili peppers, raw onions, etc. should be noted, it is appropriate to eat sesame, glutinous rice, rice, honey, loquat, sugar cane, pineapple, dairy products and other moist food. The Ming Dynasty Li Ting believes that: “cover the morning eating porridge, pushing the old to new, diaphragm nourishing the stomach, the production of fluids, people a day fresh, the complement is not small”, which is advocated in the autumn morning to drink more porridge. In winter, the climate is cold, although it is appropriate to eat hot food, but dry and hot things should not be eaten too much, so as not to make the internal Yang Qi depression and heat. The taste of the meal can be appropriately thick and heavy, with certain lipids. Because there are fewer green leafy vegetables, attention should be paid to the intake of a certain amount of yellow green vegetables, such as carrots, rape, spinach and mung bean sprouts, etc., to avoid vitamin A, vitamin B2 and vitamin C deficiency. In order to defend against wind and cold, you can use more spicy foods in condiments, such as chili, pepper, onion, ginger, garlic, etc. In addition, stewed meat, boiled fish, hot pot can also eat a little more. Winter avoid sticky, hard, cold food, such as Yin, easy to hurt the spleen and stomach of Yang. For people who are weak and old, winter is the best time for dietary supplements. This refers to the differences in diet due to people’s age, physique and occupation. First, the dietary requirements of different ages. The fetal period is the period from conception to delivery, in order to make the fetus congenitally nutritious, it is extremely important to strengthen the dietary nutrition of pregnant women during this period. The overall dietary requirements are delicious and light, nutritious, should not eat too much cold, hot, spicy and greasy food. Specifically, in the early stage of pregnancy, it is advisable to have a small but fine diet, with fresh vegetables and fruits, and avoid eating fishy and spicy stimulating products, so as not to aggravate the pregnancy reaction. In the fourth to seventh months of pregnancy, pregnant women should eat foods rich in protein, calcium and phosphorus. Such as phosphorus in soy, chicken, lamb, calcium in egg yolk, dairy, shrimp, and fish rich in protein. In late pregnancy, pregnant women should eat more high-quality protein and pay attention to the consumption of animal and vegetable proteins together. The neonatal period is the period from the first birth to the full moon. It is important to breastfeed at this time. Breast milk not only contains the nutrients that children need, but also contains more antibodies. Infancy is the period from full term to 1 year of age. This period of feeding, the best breast milk; if you can not feed milk, milk or milk powder substitute, and the need to add supplementary food, such as vegetable water, egg yolk, fruit puree, minced meat, etc.. Early childhood, refers to the period from 1 to 3 weeks of age, food should be fine, rotten, soft, neither give the child to eat greasy food, and do not eat irritating food. Supplementary foods should be added from liquid to semi-liquid, to solid, from less to more, from fine to coarse. Childhood, refers to the period from 3 years old to 12 years old, in the diet, the nutritional value can be higher, more refined, so that it is fully digested, absorbed and utilized; in addition, the amount of food should be restrained. Adolescents grow rapidly and have a strong metabolism, so they must take in nutrition comprehensively and reasonably, and pay special attention to protein and caloric supplements. For this reason, you should ensure adequate meal size and consume the right amount of fat. The diet commonly used by healthy middle-aged people, generally in addition to the normal calorie diet, is to consider giving a high-calorie, high-protein diet respectively in the case of increased labor. The so-called normal-calorie diet is generally considered to require about 1 gram of protein per kilogram of body weight per day, 0.5 to 1.0 grams of fat, about 400 to 600 grams of sugar per day, and various other minerals and vitamins, mainly supplemented by side foods. The diet of the elderly must ensure the content of calcium, iron and zinc, each person needs 0.6 grams, 12 mg and 15 mg per day, respectively. When people reach old age, the metabolic process in their bodies is mainly catabolic, so they need to replenish these consumptions in time, especially the consumption of tissue protein, which is calculated at 1 gram per kilogram of body weight per day. In addition, the elderly should pay attention to the mixed consumption of rice, flour and mixed grains, and should try to mix them in one meal to improve the utilization value of protein in staple foods. Second, the dietary requirements of different body types. For yin deficiency body, should eat more yin food, such as sesame, glutinous rice, honey, dairy products, sugar cane, vegetables, fruits, tofu, fish and other light food, for onion, ginger, garlic, pepper and other pungent products should be eaten less. Yang deficiency of the body, should eat more warm Yang food, such as mutton, dog meat, deer meat, etc. In the summer three volts, each volt can be eaten with seeds porridge or mutton with seeds soup once, with the heaven and earth Yang Wang time, in order to strengthen the Yang of the body. For people with Qi deficiency, they should pay attention to Qi supplementation in their diet, and they can always eat the medicinal food “ginseng and lotus meat soup”; japonica rice, glutinous rice, millet, yellow rice, barley, yam and jujube, all of which have Qi supplementation effects, and they should also eat more of them. For people with blood deficiency, they should eat more mulberry, lychee, pine nuts, black fungus, turtle, goat liver, sea cucumber and other foods, because they have the function of nourishing blood. For those who have a strong Yang constitution, they should avoid spicy and dry foods such as chili, ginger, onion, garlic, etc. For beef, dog meat, chicken, venison and other warm Yang foods, they should eat less. You can eat more fruits, vegetables and bitter melon. Because wine is pungent and hot upward, alcohol should be abstained from. For those who have the constitution of blood stasis, they should eat more foods that have the effect of activating blood and dispelling blood stasis, such as peach kernel, rape, cicada, black soybean, etc.; wine needs to be drunk for a long time, and vinegar can be eaten more often, because both have the effect of activating blood. The body of phlegm and dampness, should eat more food with spleen and dampness, phlegm dispel phlegm, such as white radish, seaweed, jellyfish, onions, lentils, white fruit, adzuki beans, etc., for fat, sweet and thick products, should not eat more. The qi-depressed physique can drink a small amount of alcohol to move the blood and improve the mood, and plainly should eat more food that can move the qi, such as Buddha’s hand, orange, citrus peel, buckwheat, fennel vegetables, citron, ham, etc. Third, the dietary requirements of different occupations. Physical workers, first of all, to ensure the supply of sufficient calories, because heat is a guarantee that physical workers can carry out normal work. For this reason, attention must be paid to the reasonable cooking and matching of meals, increasing meal patterns, improving appetite and increasing meal size to meet the workers’ needs for calories and various nutrients. In addition, more nutritious side dishes as well as vegetables and fruits should be eaten. Brain workers, brain consumption of energy accounted for 20% of the total consumption of the whole body, therefore, the brain needs a lot of nutrition. Research has confirmed that walnuts, sesame seeds, goldenseal, honey, peanuts, soybean products, pine nuts, chestnuts, etc. have a good effect of brain health and brain, can eat more. In addition, vegetables and fruits are the main source of calcium, phosphorus, iron and carotene, riboflavin, vitamin C. Therefore, brain workers should also eat more of them. As the general brain workers are less active, the consumption of fat and sugar is not large, so should not eat more food containing too much sugar and fat, otherwise it will cause too much body fat, body obesity.
