1. Purpose and significance of the study: Middle school students are the future and hope of the motherland, and only with healthy bodies can they have revolutionary capital. With the development of economy and the continuous improvement of people's living standards, there are some unhealthy phenomena in the diet of middle school students: picky eaters, overeating, partial eclipse, dieting and so on. , leading to malnutrition and reduced learning efficiency. So nutrition and health are very important for many middle school students. With the help of this topic, I want students to understand the knowledge of nutrition and health, and how to arrange their "three meals a day" and exercise reasonably. ?

Three. The results of the research?

? A reasonable and nutritious diet is of great significance to the healthy growth and study of teenagers. Maybe you will find all kinds of excuses, such as: "I am too busy studying to take care of it;" Just eat enough; See how strong I am. Do I still need it? "In fact, I used to think so. I only learned about the research study of middle school students' nutrition and health. Actually, it's not. Middle school is the growth and development period of teenagers' bodies. However, due to the pressure and tension of middle school study, we don't pay much attention to our health, but it is very bad. In the investigation, I learned a lot: among all staple foods, corn has the highest nutritional value, and it contains a lot of nutritional and health-care substances. Besides carbohydrates, protein, fat and carotene, corn also contains nutrients such as riboflavin and vitamins. These substances are of great benefit in preventing diseases such as heart disease and cancer. Carotene contained in corn is absorbed by human body and converted into vitamin A, which has the function of preventing cancer. Plant cellulose can accelerate the removal of carcinogens and other toxins; Natural vitamin E has the functions of promoting cell division, delaying aging, lowering serum cholesterol, preventing skin lesions, relieving arteriosclerosis and brain function decline, and eating more corn can also enhance people's memory and brain power.

In addition to corn, there are many nutritious fruits and vegetables: lemon can be used for skin care and beauty, disease prevention and treatment, calcium and iron supplementation, seasoning and sterilization; The potassium content of bananas is the highest among all kinds of fruits. Wipe your face and wash your hands with papaya, which can remove protein, oily and accumulated dirt. It is a good skin cleanser ... from the research study of nutrition and health, I not only learned a lot of nutrition knowledge, but also learned to contact with various disciplines, so that we learned to apply what we have learned, broadened our horizons and improved our enthusiasm and creativity. At the same time, it also cultivates our innovative consciousness and ability, information processing ability, cooperative spirit and interpersonal skills, scientific spirit and attitude, and consciousness and responsibility of paying attention to reality and human development. Our research topic in Liyang is the nutrition and health of middle school students. Therefore, we conducted a questionnaire survey among friends around us and learned that the nutritional health status of middle school students is not ideal now. I made a nutrition survey. In fact, nutrition can't cure diseases like what we know as "medical treatment", but it can preserve health and make our life easier. It is not only a science to study how to solve existing problems, but also a more important duty: to tell people how to prevent, how to avoid some troubles caused by diet, and how to improve energy through diet! So pay more attention to your nutrition absorption and healthy development. Middle school students must pay attention to the reasonable collocation of food in order to obtain all kinds of nutrients necessary for human body and avoid eating meat or vegetarian food. Pay attention to the complementary function of protein, and better absorb it. After the survey results came out, we also gained a lot and learned how to develop good eating habits and pay attention to nutrition and health. I learned from the survey that students who skip breakfast have a high anemia rate. According to the investigation of relevant departments, the anemia rate of students who don't eat breakfast is 100%, the anemia rate of students who don't eat breakfast at home is 23.9%, and the anemia rate of students who eat at home is 8.26%. It can be seen that skipping breakfast is easy to lead to anemia and should be paid attention to by the whole society. To sum up, we call on every parent to change the old concept of adequate food and nutrition and replace it with a brand-new modern concept of nutrition, and put it into practice so that our children can grow up healthily. Through investigation, we learned to cooperate, enhanced our communication ability, cultivated our ability to process information, learned to collect and sort out information, and exercised our hands-on operation ability. Chen Xixian, this time, we studied the nutrition and health of middle school students. Middle school students are in adolescence and have special nutritional needs. green
