With the development of social 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. People pay more and more attention to diet and health, which has become a difficult problem for modern people. But it is understood that the most important factor that leads to our unhealthy is diet, and the unhealthy diet of middle school students will cause many health problems, so our group chose? Diet and health? This topic investigates the diet and health of junior high school students. Among junior middle school students, 10% students often skip breakfast, and 27% students sometimes skip breakfast. 15% of students, the amount of food for three meals is unreasonable. These are all serious unhealthy eating phenomena. Through these phenomena, we can get the reasons for the problems of junior middle school students' diet and health, let the majority of middle school students realize the relationship between diet and health, and let them know how to eat correctly to be healthy. First of all, skipping breakfast is extremely harmful.
1, the harm to the brain. Although the weight of brain tissue only accounts for 2-3% of human body weight, the blood flow of the brain is about 800 ml per minute, the oxygen consumption is about 45 ml per minute, and the sugar consumption is about 5 grams per hour. Teenagers' brain tissue is in the development stage, and their demand for blood, oxygen and glucose is higher than that of adults. If the blood sugar is too low, there will be obstacles in the conscious activity of the brain, which will inevitably affect the weight and morphological development of the brain in the long run.
2, the harm to the digestive system. Under normal circumstances, the food eaten the night before is emptied from the stomach into the intestine after about six hours. If you don't eat breakfast the next day, your stomach acid and various digestive enzymes will go away? Digestion? Gastric mucosal layer. In the long run, the normal function of cells secreting mucus will be destroyed, which will easily cause digestive system diseases such as gastric ulcer and duodenal ulcer.
3, causing arteriosclerosis is more likely to lead to obesity. Many young students are afraid of gaining weight and skip breakfast. There is no scientific basis for this practice. The human body's demand for heat is standard. If you don't eat breakfast, you will definitely increase your appetite for lunch and dinner. However, the amount of exercise after dinner is generally small, which is more likely to cause fat accumulation and lead to obesity. In addition, not eating breakfast for a long time will also cause cholesterol and lipoprotein to deposit on the inner wall of blood vessels, leading to arteriosclerosis.
4. Make you slow down: Breakfast is the energy source of brain activity. If you don't eat breakfast, your body can't supply enough blood sugar for consumption, and you will feel tired, weak, unable to concentrate, depressed and unresponsive.
5. Is chronic disease possible? Going? Body: skip breakfast and start a day's work hungry. In order to gain power, the body will use thyroid gland, parathyroid gland, pituitary gland and other glands to burn tissues, which will not only cause hyperthyroidism, but also make the body sour and suffer from chronic diseases.
6. Is the stomach possible? Rebellion? Eating breakfast at noon, the stomach is hungry for a long time, which will cause excessive gastric acid secretion and easily lead to gastritis and gastric ulcer.
7. constipation? Come out? In the case of regular meals, the phenomenon of gastrocolon reflex will naturally appear in the human body, which is simply to promote defecation; If you don't eat breakfast as a habit, it may cause gastrocolonic reflex disorder for a long time, which may cause constipation.
8. It will bring you closer to obese people: Once the human body realizes the lack of nutrition, it consumes carbohydrates and protein first, and then fat, so don't think that skipping breakfast will promote the consumption of fat. On the contrary, skipping breakfast will make you eat more for lunch and dinner. Instead of losing weight, you will get fat.
Nutritionists have confirmed that breakfast is the most difficult meal for everyone to turn into fat in a day. Don't eat breakfast every day, just eat more lunch.
Secondly, the ratio of breakfast, lunch and dinner is preferably 3: 4: 3, so that the essence you eat in a day can be consumed at the most vigorous time.
In terms of diet:
2 1% people eat too much fat, grease and dessert;
20% people eat too much dairy products;
13% people eat too much high-protein food;
1.8% people have insufficient vegetable intake;
36% people have insufficient fruit intake;
22% people don't eat enough grain;
There are 1 1% people who are undernourished in their diet;
Only 12% people barely meet the healthy diet pagoda.
To sum up, the dietary status of junior high school students is not optimistic. In addition to investigating their dietary behavior, we also carefully investigated their dietary awareness:
Only about 1∕5 people have a strong concept of healthy eating; More than 1∕2, not enough attention;
Third, on the whole, students' healthy eating concept is relatively weak, so junior high school students must establish correct eating concept and further strengthen the cultivation of correct healthy eating habits. realize
Eat more sour foods in spring, such as foods containing vitamin C, fruits containing organic acids, and sweet and sour dishes. Scientific research has found that these sour foods contain certain substances, which can double the absorption rate of inorganic salts such as calcium, iron and zinc.

The weather is hot in summer, and bitter food, such as bitter gourd and oily wheat, has the effect of clearing away heat and reducing fire. Proper intake of this kind of food is good for health.
The dry climate and cool weather in autumn are opportunities to nourish lung qi. Spicy food, such as ginger and garlic, can be added to improve immunity and blood circulation.
Cold weather in winter is water, which is a good opportunity to tonify the kidney. Therefore, we should eat more black food with heavy taste, such as fungus, black beans and sesame seeds.
You must have breakfast, which is essential every morning. Try not to eat greasy food, and eat too much greasy food in the morning, such as fried dough sticks, oil cakes, chocolates, hamburgers and so on. It is easy to get sleepy and lose concentration in the morning. The nutrition of fried flour such as fritters will also be lost.
Don't go to bed immediately after supper. This will slowly reduce the oxygen supply to the brain, which will easily lead to heartburn and indigestion and weight gain. You should stand for half an hour to sleep. At this time, you can do housework properly, such as washing dishes and mopping the floor.
Sit without crossing your legs. Because this will make the blood flow in the legs poor and affect your health. Drink more yogurt. Yogurt has more nutrients than milk, which is more helpful for digestion and absorption. It has certain disease prevention and health care functions.
Do not overeat, do not have a partial eclipse, exercise more, and adhere to a reasonable diet every day. Teenagers' physical development is extremely rapid, coupled with intense study and a lot of activities, they need to consume more calories. The calories mainly come from rice, flour, fat and protein, so middle school students should eat three meals first. Middle school students' metabolism is vigorous, bones grow rapidly, and the number of muscle cells rises linearly. Special attention should be paid to the supply of calcium, phosphorus, magnesium and vitamins A and D. Iron is needed for the formation of a large number of tissues, and anemia will occur due to insufficient supply, so iron supplementation is more important. In order to get rid of the habit of being picky about food, reasonable collocation of food, vegetables and meat can not only make the nutrients needed by the human body complete, but also complement each other (that is, the complementary effect of nutrition). Middle school students should not only pay attention to the above points, but also consider the characteristics of this period: in eating habits, it is easy to have behaviors such as uncontrolled eating, overeating, partial eclipse, taboo, picky eaters, eating snacks and dieting, and being afraid of obesity.
Family meals should be of high quality and the menu should be diversified. Daily supply of meat and eggs 100- 150g, milk or soybean milk 1 bottle, 500-750g of grain and 300-500g of vegetables. Pay attention to various vitamins. Because middle school students use more eyes, adequate supply of vitamin A helps to protect their eyesight and prevent respiratory infection. Vitamin B is related to energy consumption. Vitamin c can promote the absorption of iron. In the cold season, vitamin D supplementation should also be considered to improve calcium absorption.
To sum up, we realize the relationship between diet and health: why? Diet and health of middle school students? The answer to the question; Knowing how middle school students eat healthily, the results of our investigation have achieved the purpose of our topic.
Opening report on diet and health 2 1. Question:
Middle school is the most important and favorable period to acquire knowledge, health and physical quality. Good nutrition, proper exercise and reasonable work and rest are three important factors that affect their physical and mental development. In adolescence, the physical development is extremely rapid, the organs are increasing, and the functions of brain, heart, liver and kidney are enhanced. In addition, intense study and a lot of activities also need more calories and nutrition. The results of the national nutrition survey show that more than 95% of primary and secondary school students do not eat breakfast well, and there are some diseases such as poor eyesight, slow growth of height, inattention, emaciation, calcium deficiency and anemia. The physical quality and learning efficiency of students have obviously declined, which seriously affects the normal growth and development of students. It is against this background that we decided on this theme. This group mainly focuses on the breakfast of high school students.
Second, the feasibility study:
Middle school students are the future and hope of the motherland, and healthy body is the capital of revolution. 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 breakfast and exercise reasonably.
Third, the research plan:
Design? Middle school students' nutrition and health? Questionnaires of
Fourth, research methods.
1.
2. Make statistics on the survey results of the questionnaire.
3. Analyze the results of the questionnaire survey.
4. Go online or consult information to learn about nutrition and health.
Fifth, research hypothesis.
We carefully analyzed the current data, and in order to make the research objectives more clear, we made the following assumptions:
1 It is not common for students in our school not to eat and eat snacks on time, accounting for less than 30% of all students.
2. Doing so will lead to nutritional imbalance and affect health.
