Health tips 1, often eat midnight snack, you will get stomach cancer. ? The life span of gastric mucosal epithelial cells is very short, and they need to be regenerated every 2-3 days. This process of regeneration and repair is usually carried out at night when the gastrointestinal tract is resting. If you often eat at night, the gastrointestinal tract can't get the necessary rest, and the repair of its mucosa can't be carried out smoothly. ? Secondly, when sleeping at night, the supper you eat stays in your stomach for a long time, which can promote the secretion of gastric juice and stimulate the gastric mucosa. Over time, it is easy to lead to gastric mucosal erosion and ulcer, and the resistance is weakened. If there are carcinogens in food, for example, you often eat some fried, grilled and fried; Waxed food, which stays in the stomach for a long time, is more likely to have adverse effects on the gastric mucosa, which in turn leads to gastric cancer. ? Eating supper regularly is not only easy to induce gastric cancer, but also easy to cause arsenic-rich diseases such as obesity and diabetes. The amount of food eaten at dinner should also be properly controlled. 2, lack of sleep will become stupid. ? You must sleep for eight hours every day, and you will not get old if you have the habit of taking a nap. ? Sleep time varies from person to person. Generally speaking, everyone sleeps eight hours a day on average. The latest research shows that when people don't get enough sleep, they will accumulate so-called "sleep debt". Even if they sleep less than an hour every day for eight consecutive days, you will still feel as sleepy as staying up late. Stanford University Sleep Research Expert: The accumulated huge sleep debt will weaken people's intelligence and motor function, make people slow down, make mistakes in mathematical calculations, forget things, and make you "stupid". ? People who have the habit of taking a nap are younger. An hour in the middle of the afternoon is equivalent to sleeping for three hours at night. If you sleep eight hours a day on average. Five hours' sleep at night and an hour's nap is enough. ? You can only eat four eggs a week. ? Eating too much is bad for your health. ? Some frail patients recovering from serious illness and pregnant women eat a lot of eggs to strengthen their physique. But the effect is often not obvious, and even side effects, such as abdominal distension, dizziness, limb weakness, and even coma in severe cases. Modern medicine calls these symptoms "protein poisoning syndrome". ? People who are weak, patients who have recovered from a serious illness, and parturients will all cause gastrointestinal digestive dysfunction for various reasons. If you eat a lot of eggs at this time, it will increase the burden on the digestive system. When eggs are eaten too much, the content of protein in the body is too high, which leads to abnormal decomposition of the intestine and produces a large amount of ammonia. Once dissolved in blood, ammonia is harmful to human body. Sometimes, the undigested protein will rot in the intestine and produce hydroxyl, phenol, indole and so on. , which will lead to "protein poisoning syndrome". According to protein's digestion and absorption function, it is enough to eat 2 ~ 3 eggs a day. ? It is a wrong idea to eat fruit after meals. You should eat fruit before meals. ? Digestive environment and digestive time? The acid-base environment determines the digestion speed of food. For example, protein must be in a strong acid state, starch must be in an alkaline state, and fat must be in a neutral acidic environment. In addition, the emptying time of starchy food is about 2 to 3 hours; The emptying time of food in protein is about 4 hours; The emptying time of fatty food is about 6 to 8 hours. If the fruit is ingested alone, it will not stay in the stomach for more than 1 hour, and then it will enter the small intestine for absorption. Therefore, if you eat fruit after a meal, the digestion of the fruit will be delayed until the end, and the sugar contained will ferment, causing food corruption, abdominal distension, burping, acid vomiting, bad breath and other phenomena, and interfering with the absorption of nutrients. ? Eating fruit before meals won't hurt your stomach? The determination of food pH depends not on tongue and taste, nor on the color change of chemical test paper, but on the type and content of minerals contained. After the fruit is absorbed by the human body, the organic acids contained in it are decomposed, leaving minerals that are alkaline and can help maintain the acid-base balance of the human body. 5. It's better not to drink green tea when the girls have their period. ? Green tea plays a very important role in human health, but even the best food has certain dietary taboos. For menstrual women, drinking green tea is not only bad for their health, but also may bring some trouble to their health. ? Menstrual women face a lot of blood loss, and iron, an important element in hemoglobin synthesis, is also lost with blood. According to the research, in addition to the normal iron loss of human body, women will lose 18-2 1 mg of iron in each menstrual period. Therefore, we often encourage women to supplement some iron-rich foods at this time, such as black fungus and pig liver, so as not to cause iron deficiency anemia. However, if you drink green tea during menstruation, these efforts will be in vain. Because green tea contains more tannic acid, it will combine with iron molecules in food to form a large number of sediments, which will hinder the absorption of iron molecules by intestinal mucosa. Studies have shown that the stronger the green tea is, the greater the obstacle to iron absorption, especially after drinking tea. ? Therefore, women and people with anemia, it is best to drink less strong tea. ? Secondly, women often have symptoms of constipation during menstruation. According to research, this is related to the secretion of luteinizing hormone. Too much tannic acid in green tea will also aggravate constipation symptoms, because tannic acid has astringent effect, which can slow down intestinal peristalsis, and then lead to stool retention in the intestine. ? Thirdly, during the menstrual period, women are often accompanied by different degrees of mental stress, headache, breast pain and other reactions due to changes in neuroendocrine regulation function. In order to avoid these reactions, we should control our emotions and not get too excited. However, caffeine, theophylline and other substances in tea have an exciting effect, which will aggravate menstrual reactions such as dysmenorrhea, headache and backache. ? 6. Drink soy milk without eggs and sugar? Dietary taboo is an important concept in Chinese medicine, because any food has cold, hot, warm and cool properties, and they will interact with each other. With a good match, the effect can be doubled; Improper collocation will reduce the absorption of food nutrients and even cause toxic reactions. ? Soymilk is sweet, and contains many nutrients such as plant protein, fat, carbohydrate, vitamins and minerals. Drinking alone has a strong nourishing effect. However, there is a special substance called trypsin, which, when combined with ovalbumin in egg white, will cause the loss of nutrients and reduce its nutritional value. ? Cooking eggs with sugar will make amino acids in protein of eggs form a combination of fructosyl lysine. This substance is not easily absorbed by the human body and will have a negative impact on health. ? 7. Don't eat tomatoes on an empty stomach. ? Tomatoes contain a lot of soluble components such as colloid, polysaccharide and lung phenol. These substances will react with gastric acid to form insoluble "stones", thus blocking the pylorus, the outlet of the stomach, increasing the internal pressure of the stomach, causing acute gastric dilatation, abdominal pain, vomiting and even hemorrhagic shock. ? 8, don't eat three hours before going to bed, it will be fat. ? It is best not to eat anything for three hours before going to bed. When we sleep, our intestines and stomach will also rest, so sleeping immediately after meals will have an impact on digestion and absorption. Sleep when there is no activity, and you don't need too many calories the next morning, so those foods will be stored and become fat on your body! ? When you sleep at night, your body only secretes insulin. The task of insulin is to lower blood sugar and promote fat accumulation. Therefore, it is a healthy eating habit to have dinner early, or eat some simple snacks and go to bed after complete digestion. ? & lt/B& gt；
