Eating three meals a day is very full, which makes the stomach so full that there is almost no room for contraction, which will not only reduce the peristalsis function of the stomach, but also make the stomach prematurely aging due to long-term overwork. In order to digest too much food, it will also increase the burden of digestion, excretion, breathing and blood circulation system. Long-term overeating will accelerate the aging process and reduce physical fitness; Overnutrition can lead to endocrine disorders and skin diseases.
Overweight not only makes the body often in a state of fatigue, as the saying goes, it also makes the brain nerve in a state of fatigue, and makes the part of the brain nerve responsible for digestive function fully develop, but the nerve responsible for intellectual function can not develop effectively, thus affecting intellectual development.
Because breakfast bears the main part of the calories needed for a day, you can eat up to 89%, and the quality of breakfast should be as good as possible, that is, there should be not only starch food to get sugar, but also some fat and protein.
You can only eat seven minutes full for dinner. If the dishes are rich and of high quality, you should only eat five or six minutes full.
When you are too busy working and hungry, you will easily faint because of the low sugar in your blood. Even if you don't faint, you will not only be physically exhausted, but also have a groggy brain. Of course, it is difficult to engage in mental work. Overeating
Cheap or even free meals, you can't eat too much when you meet your favorite meals; Then there are bets, booing, choking fire, and overeating in order not to admit defeat. Afterwards, people will not only suffer, but also hurt their internal organs. Some even become seriously ill, and others will die because of overeating. These lessons should be carefully remembered, so that unfortunate events will not be repeated, nor will the body and brain be harmed. The ancients said, "When the diet doubles, the intestines and stomach are injured." In fact, if the diet doubles, it will not only hurt the intestines and stomach, but also other parts, and even hurt the function and life of the brain.
in a word, we should always keep a regular and quantitative attitude towards drinking and eating. Quantitative aspects should also leave room for the stomach. Eating three meals a day without breakfast is the result of people adapting to the circadian rhythm formed by the rotation of the earth. In order to have strong physical strength and flexible brain power to finish the morning work, breakfast is indispensable for us. If you don't eat breakfast, you will not only have insufficient physical strength and poor brain power for half a day in the morning (such as poor memory for one day), but also disrupt the normal working order of the whole digestive system, hinder juice excretion and provide environmental conditions for bile to deposit stones because it can't be excreted in time.
getting up early, drinking a cup of warm water and taking some exercise (outdoor exercise is better) are effective measures to solve the problem of not wanting to eat in the morning.
Lunch is to provide nutrition for half a day's work in the afternoon, and the digestion and absorption function of the body is also strong during the day, so the quality of lunch should be as good as possible, that is, there should be protein and fat to meet various needs of the body.
Dinner is not only a supplement to consumption in the afternoon, but also a nutrition for rest in the evening (maintaining basic metabolism) or preparation for entertainment or work. However, because rest and sleep are the main things after dinner, there is not much demand for calories and nutrients, and the quality requirements are not too high. In fact, because dinner is eaten at home and it is a time for family reunion, it is often of high quality and eaten much.
The result of too rich dinner is that you can't sleep at night because the food is still being digested. Too much nutrition can't be consumed, but it turns into fat and accumulates under the skin, which makes people obese. Overnutrition makes people want to eat early, but excessive bile will be deposited in the gallbladder because it can't flow out in time, and gallstones may be formed over time. This is an extremely painful disease.
In fact, some nutritious food eaten in the evening should be moved to the next morning to make breakfast better and more comfortable. Eating fast food often
For bachelors who go out on business or work in other places, eating fast food is indeed economical, convenient and time-saving, and some people eat foreign fast food as a kind of freshness and psychological satisfaction, which is beyond reproach. However, it is not advisable to take bread, sausage and instant noodles as daily meals on the principle of convenience, because it will lead to: incomplete nutrition, especially insufficient intake of minerals, vitamins, fat and protein or monotonous varieties; Excessive intake of preservatives, preservatives and other chemical synthetic substances, some fast food will also add artificial colors or artificial flavors, artificial sweeteners and so on.
In a word, fast food will lead to a serious shortage of nutrients needed by the body and brain, but a lot of unnecessary or even harmful artificial chemicals are ingested, so eating fast food often is not good for the health of the body and brain, or even harmful. Partial eclipse or picky eater
Partial eclipse refers to eating only certain kinds of food, and the scope of picky eaters is narrower than that of partial eclipse, and the mood of being picky about food is stronger. These two methods are not desirable. Ryotaro, the former governor of Tokyo, who has lived over 8 years, has a famous saying: Everything on the table is delicious. This tells us that we can't be partial eclipse, let alone picky eaters.
People who only eat food and meat but don't eat vegetables are more common in contemporary urban children. Such children will have the common manifestations of meat eaters, such as impatience and low intelligence level. Vegetarians who only eat food and vegetables will also be weak because of incomplete nutrition.
For those who are difficult to eat certain or some divine foods due to congenital or acquired factors (such as those who don't eat meat, those who don't eat big oil, etc.), we should try our best to expand the variety of foods on the premise of respecting personal special circumstances, so as to make up for the lack of nutritional components caused by partial eclipse.
in addition, people have a process of adapting to a new food, and they are not told that they can't adapt after eating it once, so they may never adapt in the future. For example, potatoes, tomatoes, fennel, celery, cauliflower and other vegetables, when they first met, many people did not adapt, and almost vomited at the entrance, but now they have become common dishes. Just like some wines and drinks, people don't want to drink them at first, but they will like them after a few drinks.
Therefore, people should enjoy every kind of food given to us by nature, and try their best to taste every hot food or cold food carefully prepared by chefs or housewives for us.
Sixteen Appropriate Health Preservations says, "Everything should be at room temperature". That is, we should say warm food. However, some people like to eat hot food or even hot food, which is not good for health. Overheated or scalded food will damage the mucous membranes in the mouth, esophagus and stomach, which also destroys the tissue structure that protects these parts. If this continues, it will be harmful to the health of these parts. Some old Chinese medicine practitioners pointed out that the incidence of esophageal cancer and gastric cancer is closely related to eating hot food and scalding food. In addition, hot food and scalding food are also easy to hurt qi, that is, lung qi, which is not good for health.
Another tendency is to eat cold rice, eat cold food and cold rice, eat more cold dishes, and drink cold beer, soda, etc. These things not only hurt the stomach and spleen, but also hurt the kidneys over time. Injury to the stomach causes flatulence, acid swallowing and upset, injury to the spleen causes loss of appetite, indigestion and weakness of limbs, and injury to the kidney causes chills, sore waist, tiredness and laziness, and so on. These symptoms will affect brain function and hinder intellectual activities because of upsetting people and general discomfort. Eating salty, spicy, sour and sweet < P > Salt plays an important role in keeping body fluids slightly alkaline, improving food taste and making people powerful, but we should not overeat salty taste. Eating too much salt can lead to hypertension, cardiovascular disease and kidney disease, which will affect brain function. Needless to say, when salt enters the body, due to the osmotic pressure, the water in intracellular fluid will seep out, and the cells will be tight because of lack of water, and the tight cells will lose their vitality. Drinking a lot of water due to excessive salt and thirst will increase blood pressure, increase the burden on the heart and kidneys, and the tightly bound cells will absorb water due to the change of osmotic pressure, and make the cells relax due to bulging, thus losing their normal functions.
As for spicy food, occasionally eating a little will adjust the taste, promote appetite, drive away cold and dampness by promoting blood circulation, sterilize, warm the middle warmer and help yang, but if you eat a lot often, it will be bad for your health and intellectual activities. Especially in northern China, because it is not as humid and turbid as Sichuan, Hubei, Hunan, Anhui and other provinces, northerners should not overeat peppers, and raw onions and garlic should not be eaten in large quantities often, otherwise it will easily lead to heat and phlegm, and it will easily make people impatient and furious. Writers and scientists who are quick-witted, politicians who are broad-minded and have both ability and political integrity are not spicy food lovers, which also shows that overeating spicy food is unfavorable to intellectual activities.
Chinese medicine says that pungent (spicy) energy consumes gas and hurts gas. Because most mental workers have less physical activity and exercise, their physique is poor, and physical weakness and shortness of breath are more common. Therefore, mental workers should not overeat spicy food.
Vinegar is a kind of food that is very beneficial to people. Adding some vinegar in the diet has many good effects on stimulating appetite, regulating pH in the body, reducing the hobby of salt and prolonging life. Chinese medicine says that acid entering the liver shows that vinegar has the function of protecting liver. There is vinegar vapor indoors when a cold is prevalent in winter, which can also prevent colds. But vinegar should not be eaten in excess. Because too much will hurt teeth, stimulate gastric mucosa, hinder the absorption of calcium in the body, and so on.
In addition to the harm of white sugar to the health of the body and brain, sweet potatoes, various fruits, dried persimmons, dates and other foods with high sugar content should not be eaten in excess, otherwise it will damage the spleen and stomach (using less to strengthen the spleen and stomach, but using more will hurt the spleen and stomach), causing people to swallow acid and stomach discomfort (that is, heartburn and sour water).
in short, spicy, salty, sweet and sour, a small amount of it is good for the body and brain. But if you eat too much and eat a lot for a long time, it will be counterproductive. This is also a reflection of the philosophical truth that extremes meet. Smoking
In recent years, there have been many studies on the harm of smoking at home and abroad. For example, pregnant women smoking or passive smoking can cause fetal malformation or hypoplasia, or weak limbs. Because carbon monoxide in smoke has asphyxiating effect, it may also cause dystocia and stillbirth. Fetuses or young children develop in a smoky environment and their intelligence level is also low.
Smoking in adults can trigger many diseases, especially the occurrence of liver cancer is most closely related to smoking. Adults like smoking when thinking. It is not that cigarettes can promote thinking, but only a subconscious activity, just like non-smokers have to fiddle with things when thinking. Carbon monoxide in cigarettes has asphyxiating effect, which prevents oxygen from combining with hemoglobin and can only damage intelligence. After poisoning, some patients become mentally retarded and close to vegetative state, which can best explain the harmful effect of carbon monoxide on intelligence.
It should also be noted that although the brain is a big energy consumer, it needs a variety of nutrients and oxygen supply in complex brain activities, but the more heat energy is supplied, the better, and the more other nutrients are not the better.
However, some people have a lot of inappropriate understanding of nutrition, so that they eat a lot of foods with high protein, high fat and high calorie, and even abuse supplements, and form a daily routine. As a result, new health problems are caused by excessive supplementation and overnutrition, which also needs attention.
