The pyramid of healthy diet is divided into seven layers, and the top level is dessert and butter. Followed by: dairy products, fish or a small amount of red meat, nuts and beans, vegetables and fruits, whole wheat and vegetable oil, the bottom layer has nothing to do with food-long-term and appropriate physical exercise. Analyze the first layer of the pyramid layer by layer: butter and dessert. Whether it is the old pyramid or the latest pyramid proposed by Professor Willett, butter and dessert are listed at the top. It can be seen that this kind of food has almost no other effects except increasing calories and fat, let alone being beneficial to health. If you want to keep a graceful figure, you'd better stay away from the food on this floor; But if you need to do a lot of physical exercise, such as long-distance running and swimming, you can eat a piece of chocolate before exercise to supplement your strength and calories. The second floor: dairy products In the old pyramid, dairy products are on the second floor with meat. Professor Willett put dairy products on the second floor separately because eating too much dairy products will increase the burden on the heart and lead to higher cholesterol, and its side effects are greater than meat. Some people emphasize that dairy products can increase calcium in the body. In fact, dairy products are not the only or the best way to get calcium. Experiments show that the calcium provided by two cups of milk is only equivalent to the calcium supplemented by several mouthfuls of tofu. Of course, you don't have to change the habit of drinking milk every day, but it is more reasonable to drink skim milk as much as possible. The third layer: The meat quality of fish or a small amount of red meat seafood is called "white meat". These meats are rich in protein and various amino acids, and will not be converted into fat, so they can be properly ingested 2 ~ 4 times a week. Excessive intake of other "red meat" foods will lead to an increase in the incidence of cardiovascular diseases, especially animal viscera. It is best not to eat them often. Even for young people, too high cholesterol index will also lay a disaster for the future. Layer 4: Nuts and beans are neglected in the old pyramid, and Professor Willett just thinks they are very important. Many people think that nuts can lead to fat accumulation. In fact, the oil in nuts belongs to vegetable oil, which is cleaner than the oil in animals and contains more vitamins and other nutrients. Bean products contain a variety of trace elements, especially calcium, which is very beneficial to people with osteoporosis and the elderly. The fifth layer: the importance of vegetables and fruits to human health need not be overemphasized. Within the scope allowed by the "stomach", we should eat as many of these two kinds of foods as possible that are most beneficial to our health. Layer 6: Whole wheat food and vegetable oil In the old pyramid, vegetable oil was not included in the edible range. In real life, vegetable oil is an indispensable ingredient in the cooking process. At the same time, vegetable oil is not as high in calories as expected. On the contrary, the trace elements contained in it can provide substances needed by the body, which should be said to have more advantages than disadvantages. The seventh layer: long-term and appropriate physical exercise Professor Willett unexpectedly listed physical exercise as the "foundation" of the pyramid. He believed that a perfect diet structure should be based on a healthy lifestyle. Life lies in exercise. Only by combining exercise with scientific diet can we keep our body in the best condition. [Edit this paragraph] Modern medical research shows that there are no fewer than 1 kinds of nutrients needed by human body, some of which can be synthesized and manufactured by themselves, but there are about 4 kinds that cannot be synthesized and manufactured by themselves. After careful division, seven kinds of nutrients can be summarized: (1) protein and protein are the foundation of all life, and they are constantly synthesized and decomposed in the body, which is an important component of constructing, renewing and repairing tissues and cells. Meat, eggs, milk, fish and beans are the main nutrients for protein. (2) Fat is one of the sources of energy, which assists the absorption of fat-soluble vitamins (A, D, E, K and carotene), protects and fixes internal organs, prevents heat from disappearing, and keeps body temperature. Grease is the main nutrient to provide fat. (3) Vitamins are essential substances to maintain human health, and the required amount is less, but they must be taken from food because they cannot be synthesized in the body or the synthetic amount is insufficient. Vitamins are water-soluble (vitamin B, vitamin C) and fat-soluble (vitamins A, D, E, K, etc.). They are very important for the normal growth and development of human body and the regulation of physiological functions. Vegetables and fruits are the main nutrients to provide vitamins.

Vegetables and fruits are the main nutrients that provide minerals. (6) Water is the main component of body fluids in human body, which is necessary to maintain life, accounting for about 6% of body weight. It has the functions of regulating body temperature, transporting substances, promoting chemical reactions in the body and lubricating. The source of water is mainly the water we use every day to maintain the body's needs. (7) Cellulose: It belongs to carbohydrates. Include cellulose, hemicellulose, lignin, pectin, etc. After ingestion, it will not be digested and absorbed by the human body, forming waste residue. Excretion with stool. It can promote intestinal peristalsis, and at the same time absorb excess fat and cholesterol and excrete them; Effectively prevent cardiovascular diseases and gastrointestinal diseases in adults. . (7) Dietary fiber refers to the components in plants that cannot be digested and absorbed, and is an indispensable factor for maintaining health. It can soften intestinal substances, stimulate gastric wall peristalsis, and assist defecation. And reduce the absorption of cholesterol and glucose in the blood. [For an adolescent, maintaining mental health should do the following: (1) Psychological characteristics are consistent with age. Teenagers' psychological processes such as cognition, emotion and will, as well as their personality characteristics, should conform to the law of age growth. It is not as simple and naive as childhood psychology, nor as mature as adults, but shows the characteristics that teenagers should have, which is the basic condition of mental health. (2) Maintain an optimistic and stable mood. Optimistic and stable mood helps to improve the efficiency of study and work. In difficulties and adversity, maintaining an optimistic mood will enhance self-confidence. Optimistic and stable mood is an important sign of mental health. (3) Love learning. Learning is the leading activity in adolescence, which lays the foundation for entering adulthood and society. Clear the purpose of learning and cultivate interest in learning, you will take learning as a pleasure and take the initiative to learn, so that learning will not become a burden. Not only will it not increase psychological pressure, but it will also be beneficial to mental health. (4) Establish good interpersonal relationships.

In dealing with people, we should treat others equally, respect and understand others, and be ready to help others. We should establish proper friendship with our classmates and find our bosom friends.
