"Moderate diet" is one of the experiences of the ancients. Guan Zi once pointed out: "A frugal diet is good for health and longevity; If you don't eat well, you will be tired and you will lose your life. " The so-called diet control means that the diet should be moderate, not arbitrary, and pay attention to the science and methods of diet. Specifically, it is necessary to pay attention to the amount of food and the time of eating.

Old Chinese medicine believes that regulating diet and nourishing the spleen and stomach is the main factor for the elderly to keep fit. They like to eat whole grains produced locally, especially vegetables, beans and fruits, and eat less fish and meat. Although some people are partial to fish, they are also mixed with meat and vegetables, and they are never satisfied. Their feeding experience is: one is not full, the other is not salty, the third is not sweet, the fourth is not fat, and the fifth is not partial eclipse. Some old Chinese medicine practitioners regard Yuan Mei's poems in the Qing Dynasty as a guide to diet and nutrition, that is, "longevity is only due to eating less, but not being full is really a cure."

Eating too much is bad for your health, but eating too little is also bad for your health. Some people think that eating less is better. As a result, they forced themselves to starve. They are weak because their bodies can't get enough nutrition. The correct way is to "measure the amount of abdominal pain", that is, to decide how much to eat per meal according to your usual appetite. Where there is food, there is no hunger and satiety-this is called preserving the five internal organs. This is the principle of eating in moderation. Only in this way can the five internal organs not be injured by hunger.

2. Eating Sometimes, three meals are different.

As the saying goes, "Have a full breakfast, a good lunch and less dinner. A large number of experiments show that paying attention to the reasonable arrangement of three meals a day is of great benefit to health and longevity.

Eating nutritious breakfast every day is one of the elements to prolong life. Therefore, we must have a good breakfast. Choose the most reasonable nutrition for your body. It should include at least four parts: grain, animal food, milk and vegetables and fruits. Breakfast should not only pay attention to quantity, but also pay attention to quality. It is best to eat less carbohydrate-rich foods such as porridge, sweet bread or fried noodles to avoid increasing serotonin in the brain. Breakfast should also be changed, not the same, at least one staple food should be changed every week. And breakfast should not eat foods containing a lot of fat and cholesterol, such as fried dough sticks and bacon, which is not only difficult to digest, but also accelerates the rise of cholesterol.

Pay attention to the diversity of lunch food, pay attention to the collocation of meat and vegetables, and be nutritious. There must be some foods rich in protein and fat, such as fish, meat, eggs and bean products. And there must be staple food, such as rice, steamed bread, corn flour cake, tofu and so on. It is also necessary to match some fresh vegetables to keep the blood sugar in the body at a high level and ensure the work and study in the afternoon.

According to the scientific diet, dinner should be light and easy to digest, and it is best to choose noodles, rice porridge, fresh corn, beans, vegetarian buns, side dishes, fruit platters and other foods. And eat two hours before going to bed, pay special attention not to eat meat, and it is best to eat 80% full.

3. Reasonable collocation and impartiality.

The human body has many requirements for nutrition, and a reasonable diet can ensure all kinds of nutrients needed by the body. Therefore, we should avoid the monotony of partial eclipse and diet, otherwise it will have a series of adverse consequences. A reasonable diet is to choose a variety of foods, so that the nutrients contained are complete and the proportion is appropriate to meet the needs of the human body.

Coarse grains should be matched with flour and rice: a reasonable combination of coarse and fine grains can improve the flavor of food, help supplement various nutritional components and improve the nutritional value and utilization rate of food.

The types of non-staple food should be varied, and the combination of meat and vegetables: meat, fish, milk, eggs and other foods are rich in high-quality protein, and all kinds of fresh vegetables and fruits are rich in vitamins and inorganic salts. The combination of the two can cook a variety of delicious dishes, which are not only nutritious, but also stimulate appetite, which is beneficial to digestion and absorption.

The collocation of staple food and non-staple food: staple food refers to food crops mainly based on carbohydrates. The staple food can provide the main heat energy and protein, and the non-staple food can be supplemented with high-quality protein, inorganic salts and vitamins.

Dry and wet diet collocation: the staple food should be dry and wet according to the specific situation, which can increase satiety and help digestion and absorption.

Adapt to seasonal changes: the diet in summer should be light and refreshing, and hydrochloric acid food should be appropriately increased to increase appetite and supplement salt loss caused by sweating. Winter meals can increase oil content appropriately to increase heat energy.

4. The food should be light and avoid being too salty.

A light diet means eating less salt. Ancient health experts believe that salty food is harmful to health, while light food prolongs life. In the Tang Dynasty, Sun Simiao put forward the argument that "more salt leads to longevity". In the Ming Dynasty, Chen Jiru quoted three elder brothers from Dongguang County in Jianpiyu. Because there is little salt in this area, it is mainly light, and they are all over 80 years old and very strong. One of the reasons why people in court live short is that they eat too much salt.

As for why salt damages life, the ancients thought that salt can coagulate blood and stagnate qi. For example, there is salt and brine caking in soybean milk, and salt caking in animal blood. Therefore, people who eat more salty taste have a haggard face and blood vessels are blocked. If you often eat light food, you will naturally feel refreshed, you will live longer and have fewer diseases. It has been proved that overeating is related to diseases such as hypertension and gastric cancer.

5. Pay attention to food hygiene and develop good habits.

Chew your food carefully, don't wolf it down. Chewing is the first step of digestion. The finer you chew, the better it is for digestion and absorption.

Don't be distracted by eating. You need to concentrate on eating. Don't think about other things when eating, or read books and watch TV, which will not only affect appetite, but also affect the secretion of digestive juice, which may cause stomach problems after a long time.

Too thirsty to drink. If you drink too much water at a time, it will quickly enter the blood and increase the burden on the heart and kidneys. If you drink plenty of water before meals, it will dilute the gastric juice and affect the digestion of food.

Don't eat when you are angry. Have a happy mood when eating to promote the secretion of gastric juice and help the digestion of food. If you barely eat in a rage, it will cause your stomach to swell and even pain. Eating should be calm and absorbed, which is beneficial to the digestion and absorption of the spleen and stomach.
