The saying “the way to maintain health is better than food”, and the saying “medicine and food have the same origin” and “medicine is better than food”, all emphasize that eating the right food is more useful than the elixir. Food not only supplies the body with energy, but also satisfies the spiritual needs. Diet is indeed the most important part of health care. A proper diet can make a person strong and longevity. Improper diet, on the other hand, is one of the major causes of disease and premature aging. Therefore, ancient Chinese health practitioners attach great importance to the diet of moderation, and through long-term life practice, has accumulated a wealth of dietary health methods and experience. The following can be used for health practitioners to learn from: 1, diet in moderation, the body benefits life “diet in moderation” is one of the experiences of the ancient people. Guanzi has pointed out: “diet section, the body is beneficial and life benefit; diet is not, the shape is tired and life loss.” The so-called diet is moderate, means that the diet should be moderate, not arbitrary, to pay attention to the science and method of eating. Specifically, we should pay attention to the amount of diet and eating time. Old Chinese doctors believe that regulating the diet to nourish the spleen and stomach is the main factor of fitness for the elderly. They love to eat local production of grains and cereals, more vegetables, beans, fruits, and less fish and meat to eat. Although there are some individuals who prefer to eat fish and meat, but also meat and vegetarian, never but addicted. Their food experience is: one is not full, two is not salty, three is not sweet, four is not fat, five is not partial food. Some old Chinese medicine to the Qing Dynasty Yuan Mei’s poem as a food guide, that is, “longevity is only because the meal is less, not full really but the disease formula.” Too much is not good for health, but too little food is also detrimental to health. Some people unilaterally think that the less you eat the better, the result of forcing themselves to starve, because the body does not get enough nutrition, 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 be hungry and full and hurt the five organs. 2, eating sometimes, three meals are different as the saying goes: “breakfast to full, lunch to good, dinner to less. A large number of experiments have shown that attention to the three meals a day reasonable arrangements for health and longevity is very beneficial. Insist on eating nutritious breakfast every day is one of the elements to prolong life. Therefore, breakfast must be eaten well. It is important to choose the most reasonable nutritional mix for the body’s needs. At least should include cereals, animal food, dairy and vegetables and fruits four parts. Breakfast should not only pay attention to the quantity, but also to the quality. It is best to eat less carbohydrate-containing foods such as thin rice, sweet bread or fried noodles to avoid increasing the serotonin in the brain. Breakfast should also pay attention to change, not the same, at least should change a major food every week. And, breakfast should not eat food containing a lot of fat and cholesterol, such as doughnuts and bacon, these foods are not only difficult to digest, but also accelerate the rise of cholesterol. Lunch food should pay attention to the variety, pay attention to the meat and vegetarian mix, nutrition all. There must be some foods rich in protein and fat, such as fish, meat, eggs, soy products, etc.; and there should be rice, steamed buns, cornmeal cakes, bean bread and other staple foods; also with some fresh vegetables, so as to keep the body’s blood sugar continues to be held at a high level, to ensure that the afternoon work and study. According to the scientific way of eating, dinner should be light and easy to digest, and the best choice is: noodles, rice porridge, fresh corn, beans, vegetarian filling buns, small dishes, fruit platter and other foods. And, should eat two hours before bedtime, but also pay special attention not to eat meat, and, preferably, eat 80% full. 3, a reasonable mix of the human body’s nutritional requirements are multifaceted, a reasonable mix of diet to ensure that the body needs a variety of nutrients, therefore, to avoid partiality and diet monotony, otherwise it will produce a series of adverse consequences. To prepare a reasonable diet is to choose a variety of food, so that the nutrients contained in a complete and appropriate proportion to meet the needs of the body. Coarse grains, fine grains to match: a reasonable mix of coarse and fine grains can improve the flavor of food, help complement various nutrients, but also to improve the nutritional value of food and the degree of utilization. Side dishes should be diverse, meat and vegetarian: meat, fish, milk, eggs and other foods are rich in high-quality protein, a variety of fresh vegetables and fruits are rich in a variety of vitamins and inorganic salts. The combination of the two can be cooked into a wide variety of delicious dishes, not only rich in nutrition, but also to enhance appetite, conducive to digestion and absorption. Staple food: Staple food refers to food crops containing mainly carbohydrates. The main food can provide the main caloric energy and protein, and the side food can supplement high-quality protein, inorganic salts and vitamins, etc. Dry and thin diet with: staple foods should be used according to the specific situation with dry and thin, so that, one can increase satiety, the second can help digestion and absorption. To adapt to seasonal changes: summer food should be light and refreshing, with an appropriate increase in salt and sour foods to increase appetite and replenish the loss of salt due to sweating. Winter meals can be appropriate to increase the fat content to increase caloric energy. 4, food should be light, avoid too salty light food is less salt. Ancient health practitioners believe that more salty injury life, light food to prolong life. Sun Simiao in the Tang Dynasty put forward a “salty promote life” argument. The Ming dynasty Chen Jiru “health skin language” example of the Dongguang County village in the three elderly brothers, because the place is difficult to get salt, so the main light, are up to 80 years old and very strong body; and the court in the short life, one of the reasons is to eat too much salt. As for why salt is detrimental to life, the ancients believed that salt can condense blood and stagnate gas. For example, soybean milk with a little bit of salty brine will become a lump, the blood of animals encountered salt is also clumped. Therefore, people who eat a lot of salty taste, the face is withered, the veins are stagnant. If you always eat light, naturally refreshing, less disease and longevity. Now it has been confirmed that the diet is too salty and hypertension, stomach cancer and other diseases related to the occurrence. 5, pay attention to dietary hygiene, good habits Food when chewing, do not gobble. Chewing is the first step in digestion, the finer the chewing, the more conducive to digestion and absorption. Do not eat distracted. Eating requires concentration, do not eat while thinking about other things, or reading a book, watching TV, both affect appetite, but also affect the secretion of digestive juices, which can cause stomach problems. Big thirst is not big drink. If you drink too much water at a time, water quickly into the blood, will increase the burden on the heart and kidneys. If you drink a lot of water before meals, but also dilute gastric juices, affecting the digestion of food. Angry not to eat. When eating a pleasant mood, in order to promote the secretion of gastric juice, which helps the digestion of food. If you are angry and forced to eat, it will cause stomach distention and even pain. Eating should be calm and concentrated in order to facilitate the digestion and absorption of the spleen and stomach.
