With the development of society and economy, people's living standards have been greatly improved, and health has become the goal pursued by modern people. However, some health problems are always testing and challenging our bodies. In particular, the health of middle school students, who are regarded as the future of the motherland, has attracted more and more attention. The diet and health of middle school students have become a difficult problem that plagues modern people. However, it is understood that the most important factor that causes us to be unhealthy is our diet. Poor diet among middle school students will cause many health problems. Therefore, our group chose the topic of "Middle School Students' Diet and Health" to investigate the issues related to middle school students' diet and health. It can be concluded that the reasons why middle school students have diet and health problems can help middle school students realize the relationship between diet and health, so that middle school students can understand that eating correctly is healthy. We will conduct surveys through questionnaires, searching for information online, and interviewing students, which are the main ways to obtain information. In addition, we also consulted some books and obtained a small amount of information. According to information found online, for most people, entering middle school also leads to a leap stage of growth and development - adolescence. Good nutrition affects the development of the body and is particularly important. Therefore, preventing the occurrence of nutritional deficiencies requires a scientific and reasonable diet to nip them in the bud. Physical development in adolescence is extremely rapid, coupled with intense study and high activity, so more calories are needed. The calories mainly come from the staple food of rice, noodles, fat and protein, so middle school students should eat three main meals first. Middle school students have strong metabolism, rapid bone growth, and a sharp increase in the number of muscle tissue cells. Special attention must be paid to the supply of calcium, phosphorus, magnesium, and vitamins A and D. The formation of a large number of tissues requires iron, and if the supply is insufficient, anemia may occur, so iron supplementation is more important. It is necessary to abandon the habit of picky eating and food selection. A reasonable mixture of grains and vegetables, and a combination of meat and vegetables can not only complete the nutrients needed by the human body, but also complement each other (that is, the complementary effect of nutrition). In addition to paying attention to the above points in the diet of middle school students, , the characteristics of this period should also be considered: in terms of eating habits, they are prone to uncontrolled eating, overeating, partial eclipse, food taboos, picky eaters, snacking, and dieting and fear of obesity. Therefore, they should be helped to get rid of such unhealthy behaviors. habits. Family meals should be of sufficient quantity and high quality, and the recipes should be diversified. Daily supply of 100-150 grams of meat and eggs, 1 bottle of milk or soy milk, 500-750 grams of grain, and 300-500 grams of vegetables. Pay attention to supplementing various vitamins. Because middle school students use their eyes a lot, a sufficient supply of vitamin A can help protect vision and prevent respiratory infections; vitamin B is related to the body's energy consumption; vitamin C can promote the absorption of iron. Vitamin D preparation supplementation should also be considered during the cold season to improve calcium absorption. To sum up, we have realized the relationship between diet and health: we have obtained the answer to the question of "middle school students' diet and health"; we know how middle school students can eat healthily, and the results of our investigation have reached our level. The purpose of the subject.
