To a certain extent, good health lays the foundation for a happy life. An unhealthy body often limits a person's contact with others and greatly reduces his opportunities to get close to nature, so it is easy to form a biased character. You may also find that a frail person has a harder time developing a positive self-image than a healthy person. Don’t only care about your body when you are sick, and don’t think that improving people’s health is only the job of doctors. You, the teenage boys and girls, should improve your physical health by cultivating a healthy lifestyle. There is a famous saying in nutrition: Your body is what you eat. In many people's minds, "eating" seems to be an innate instinct. As long as you have certain financial capabilities, you can eat whatever you want, which will provide sufficient nutrients for the growing body. In fact, otherwise. The principle of "balance and moderation" emphasized in nutrition is often destroyed by our bad eating habits. I don’t know when we started to have a partial eclipse. In food, there are always some things that we try to avoid eating, including fish, meat, eggs, milk, whole grains, vegetables and fruits, and we even prefer to satisfy our hunger with sweet snacks. Over time, varying degrees of malnutrition and disease began to appear. Is it strange? No! Because our bodies are unable to obtain enough nutrients from food to maintain normal growth and development and normal metabolism. There are many kinds of nutrients needed for human growth and development. Currently, 54 kinds have been discovered and confirmed, and the number is still increasing. But in terms of its chemical properties or physiological effects, it can be divided into six categories: protein, fat, carbohydrate, vitamin, mineral and water. Long-term lack of any nutrient in the human body will lead to metabolic disorders in the body, cause malnutrition, and even lead to disease. However, so far, scientists have not found any single food that can provide all the nutrients needed by the human body. More importantly, some nutrients are necessary to maintain normal physiological and biochemical reactions of the human body, but cannot be formed in the human body. , such as most vitamins. They only exist in various foods. Only by combining foods reasonably can the human body be adequately supplied. In this sense, healthy eating habits lie not in "speciality" but in "miscellaneous". For the sake of good health, are you willing to get closer to the foods you have been neglecting? In addition, many of us often skip breakfast and eat a large dinner. This kind of eating habit violates the principle of "moderate amount". Under normal circumstances, the energy a person got from the previous day's dinner has been basically used up after a night of consumption. If you don't replenish energy through breakfast in time, you may be so hungry after the second class in the morning that you can't hear what the teacher is saying at all. In addition, eating irregularly in this way destroys the rules of gastrointestinal motility and secretion of digestive juices, and cannot maintain the normal function of the digestive tract. It is easy to suffer from peptic ulcer at a young age. A "big dinner" doesn't help your health either. Overeating at dinner will not only increase the burden on the gastrointestinal tract and affect sleep at night, but the rising insulin content in the blood can easily convert blood lipids into fat and store it in the abdominal wall. Those students who "don't eat much, but have a belly" may be because they don't have enough breakfast and lunch, but eat too much at dinner. Eating habits that comply with the principle of "balanced and moderate" require us to start with three meals a day, and achieve "eat well in the morning, eat well at lunch, and eat light and light at dinner" without being partial to eclipse. The "eat breakfast well" mentioned here means plenty and plenty of food. To do this, we need to understand some of the most basic nutritional knowledge.

We might as well divide all the foods we have access to into five major categories: The first category, cereals, mainly provides calories, carbohydrates and vitamin B1; The second category, meat, poultry, eggs, fish, milk and dairy products, mainly provides protein, Fat, calcium, phosphorus, iron and vitamins A, B2 and B12. The third category of beans and bean products mainly supplies protein, fat, carbohydrates and B vitamins. The fourth category of vegetables and fruits mainly provides fiber, minerals and vitamins. C and carotene; Category 5 animal oils, vegetable oils, refined sugar and alcohol. Only pure fat, pure carbohydrates and calories are available, also known as pure calorie foods. Among these five categories of food, the first, third and fourth categories of food can be consumed freely, the second category of food should be consumed in moderation, and the fifth category of food should be restricted. And choose different foods from each food group every day. It is important to note that excessive intake of any food or nutrient has no health benefits. Table salt provides the necessary sodium for the human body to perform physiological functions. However, excessive amounts are harmful to health. According to surveys in more than 50 countries and regions, the incidence of hypertension is very high in countries with high salt intake, such as Japan, South Korea, China, Colombia, and Portugal. Therefore, in order to prevent diseases, we need to correct our salt-loving habits starting from our teenage years. In addition, with the improvement of living standards, our chances of eating meat today are much greater than when our parents were children. Without corresponding scientific knowledge, we are likely to eat too much fat while getting rich protein. Nutritionists have found that in addition to obesity, the incidence of atherosclerosis, cardiovascular disease, cerebrovascular disease and tumors is positively correlated with the amount of fat consumed in the body. Don’t think that these diseases are only for middle-aged and elderly people. According to epidemiological studies, the incidence of these three diseases among young people is increasing year by year. If you want to prevent yourself from suffering from the above diseases in middle age, you must start paying attention from now on. From a health perspective, eating meat should be selective. There is a saying in nutrition: four legs are not as good as two legs, and two legs are not as good as no feet. That is, eating pigs, beef and mutton is not as good as eating chicken, and eating chicken is not as good as eating fish. Eating some tofu and soy milk regularly is also a good choice. Vegetables contain a lot of vitamins. Unfortunately, these vitamins are easily destroyed by oxidation during the cooking process. In order to protect the vitamins in vegetables from being destroyed, those that can be eaten raw should be eaten raw; those that cannot be eaten raw should be paid attention to during the cooking process: wash first and then cut, stir-fry over high heat and make soup to serve.
