Investigation report on diet health, 3000 words, 1
It is understood that the most important factor leading to our unhealthy is diet, and many health problems will appear in the poor diet of middle school students, 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. Slow you 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.
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 your 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 promote 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. Liver, etc. Swedish scientists have shown that excessive consumption of high-fat foods may hinder the regeneration of brain cells, thus affecting the development of memory and thinking.
This classmate's snacks are almost all junk food. Although all the foods we come into contact with in daily life can't be called protein, fat, carbohydrate, vitamins, mineral elements and dietary fiber, whether high-calorie or low-calorie foods are eaten alone or in large quantities, they are harmful to human body. But most people prefer high-calorie, high-fat and high-sugar foods, such as hamburgers, French fries, fried chicken wings and sausages. And few people like to eat tasteless and low-fat food. In this regard, Professor Yang Yuexin, director of the Food Nutrition Evaluation Office of the Institute of Nutrition and Food Safety of China CDC, said? Three highs? Food usually tastes very strong and stimulates people's taste, and once people's taste is stimulated by this delicious food, it will become addictive and it is difficult to resist the temptation of appetite. In addition, according to Professor Yang Zhaoxu? Junk food? Addictive because some fried or processed foods contain many artificial additives, such as spices, pigments, flavoring agents, leavening agents and so on. These chemicals make food irresistible in color, taste and appearance. There are also some unscrupulous traders who add addictive drugs to food, which will affect the central nervous system of the human body and make people dependent, thus making it difficult for consumers to give up these foods.
This kind of greasy food increases the indigestible factors, and often stays in the gastrointestinal tract for a long time, which is the main factor causing constipation, and promotes excessive blood inflow and retention in the gastrointestinal tract, promotes acidification of body fluids, seriously undermines the principle of healthy allocation of life resources, and brings obesity, diabetes, hypertension, hyperlipidemia, heart disease and other rich diseases.
Seven. Countermeasures and suggestions
College students must learn to eat scientifically. In essence, scientific dining needs to solve three problems. The first is the quality of diet, that is, how to choose food; The second is the amount of food, that is, how to eat and drink quantitatively; The third is the arrangement and habits of meal time, when to eat and how to eat.

A healthy diet is an indispensable prerequisite for our healthy growth. However, with the continuous improvement of people's living standards and parents paying more and more attention to their children's nutrition, why are there still overnourished students around us? Chubby? And malnutrition? Small bean sprouts? There are more and more. The reason is that some parents think that nutrition is to give their children more chicken, duck and fish, and children can eat whatever they want and drink whatever they want. Others, on the other hand, think that children can't eat this and that, regardless of their life characteristics. Pupils' period is the peak of life development. In this period, in addition to maintaining the body's metabolism, the nutrients ingested must also be stored in an appropriate amount to ensure the demand for sustainable growth and development. Once this important period is missed, it will cause irreparable losses to physical development and healthy growth. Therefore, this holiday, my parents and I investigated the unhealthy diet of primary school students by consulting materials and asking our classmates and parents around us.
I found that primary school students are partial to food and picky about food. Statistics show that 80% of primary school students don't like vegetables, 50% don't like milk and eggs, 85% don't eat a little fat, 95% like meat, chocolate and puffed food, and 90% only eat 10 kinds of food every day. Taste is the first choice for children, followed by color and shape, and finally. People's eating habits are not innate, but mainly cultivated by their parents from an early age. Nowadays, the primary school students' popular partial eclipse is actually a psychological obstacle, which is rooted in the family. Some parents give their children monotonous food, and when they grow up, they will dislike or even resent those foods that they have never eaten or often eat. Some parents say what is delicious and what is not delicious in front of their children, which also affects their psychological behavior, and gradually children's bad eating habits are formed. So here, I would like to give some suggestions to parents: educate their children on diet through various channels, and change their dietary concepts: change what children like to eat and what children should eat. Parents should set an example. Parents are the children's first teachers. Insist on letting children eat all kinds of nutritious foods every day, and constantly add new foods that children don't like to eat for their children to try. Achieve a balanced nutrition and break the vicious circle of malnutrition and partial eclipse. To put it simply: a handful of vegetables, a handful of beans, an egg with some meat and a glass of milk every day.
After investigation, many students like to eat? McDonald's? And then what? KFC? . According to statistics, 38% of primary school students admit that they like foreign fast food very much, while 50% prefer it. Generally speaking, 88% of primary school students like foreign fast food, and only 12% don't. The survey also found that 43.6% of children eat it every month? Foreign fast food? , among them? How many times a week? And then what? Almost every day? 6. 1%. Holidays, birthday celebrations and classmates' dinners are all reasons for children to eat foreign fast food. In addition, the younger the children, the higher their love for foreign fast food. 43.0% pupils like foreign fast food very much. Why are students so interested in foreign fast food? Have a soft spot? Want foreign fast food? Does it taste good？ This is the most attractive point of foreign fast food. Younger students pay more attention to toys and gifts given by restaurants. In real life, many parents reward their children with foreign fast food. Parents often like to take their children to eat foreign fast food to celebrate or as a reward for their children when they have a birthday or get good grades in the final exam. A mother said to me: Every holiday or child's birthday, we take him to McDonald's. If the child has fun, we will be happy. ? Although many people know that the nutrition of foreign fast food is unreasonable, they still like to eat it. Therefore, parents should pay attention to: let children have a clear understanding of the nutritional defects of foreign fast food and the possible consequences for their health. Restricting the frequency of eating foreign fast food can make children taste foreign fast food, but it can't be part of their daily diet. They shouldn't eat it often, every day, and they shouldn't eat it while eating. It is enough to go once every six months. Pay attention to the choice of food varieties. Varieties with vegetables, such as vegetable salad and corn cob, should be selected to supplement vitamins, minerals and cellulose. It is not advisable to eat high-calorie fried foods such as French fries and hamburgers. Don't treat eating foreign fast food as a reward for children's good academic performance or other achievements, so as to avoid children's thirst for foreign fast food.
The diet education of primary school students is an important topic, and there is a lot of room for us to explore and explore. Let's work together to improve primary school students' awareness of food safety, so that primary school students can establish a correct concept of diet and cultivate good eating habits together, so that we can thrive.

I. Introduction
In recent years, the government of China has paid more and more attention to promoting scientific and nutritious diet for residents. College students are the pillars of the country, and their nutritional improvement and correct adjustment of dietary structure are directly related to the improvement of college students' physique. However, many college students now have a series of health problems due to their ignorance of dietary nutrition or bad dietary attitudes. In order to further explore the problems existing in college students' diet, and then optimize the diet structure, improve eating habits and pay attention to food hygiene, our research group conducted a survey on the diet of students in our school.
Second, the survey related instructions
The purpose of the investigation
Through the understanding of college students' diet, this paper gradually discusses the outstanding problems and puts forward solutions to make college students have better and more scientific eating habits.
(2) survey methods
We have a lecture about students in our school, the topic is. College students' dietary health questionnaire? In the sampling survey, 100 questionnaires were distributed and 100 questionnaires were collected, and the effective rate was 100%. The survey is very popular in all departments and can truly reflect the situation of contemporary college students' diet health.
(3) Investigation time
654381October 5 to February 5, 65438.
(4) Scope of investigation
Students of Grade One and Grade Two in Wenjiang Campus of Chengdu Normal University
Fourthly, questionnaire analysis.
(1) Eating habits
(1) Are you overeating?
Choose frequent accounts for 2 1% of the total, occasional accounts for 58% of the total, and never accounts for 2 1% of the total.
Most students choose occasionally. As the saying goes, they shouldn't overeat. Don't eat enough if you want to be healthy? There is some truth in this statement. Overeating will not only destroy the digestion and absorption function of gastrointestinal tract, but also cause acute gastroenteritis, acute gastric dilatation and acute pancreatitis. Moreover, due to the rise of diaphragm, it will affect heart activity and induce heart disease. If the rescue is not timely, it will be life-threatening. Therefore, don't eat or overeat at any time.
(2) Did you drink water again in the morning?
There are 65 people who choose part, accounting for 65% of the total, and 35 people who choose no, accounting for 35% of the total.
Most students choose. This is a good eating habit. Drinking a cup of cold boiled water after getting up in the morning is beneficial to liver and kidney metabolism, lowering blood pressure and preventing myocardial infarction. Some people call it? Resurrection water? . Scholars believe that after several hours of sleep, the digestive tract has been emptied. Drinking a cup of cold boiled water in the morning can be quickly absorbed into the blood circulation and dilute the blood, so as to treat various organs in the body at one time? Internal washing? .
(3) Do you have the habit of being picky about food?
34 people chose the part, accounting for 34% of the total, and 66 people chose no, accounting for 66% of the total.
Most students are not picky about food and partial eclipse, so this eating habit is helpful to the healthy growth of the body. Because the nutrients needed by the human body are supplied by various foods, no natural food can contain all the nutrients needed by the human body. Eat only one kind of food; No matter how much you eat and how nutritious you are, you can't keep healthy. Therefore, in diet, you can't be picky eaters or partial eclipse for a long time.
(4) Drink or drink while eating?
There are 25 people who often choose, accounting for 25% of the total, 53 people who occasionally choose, accounting for 53% of the total, and 19 people who never choose, accounting for 19% of the total.
Most students choose occasionally. It is best not to drink water or drinks when eating. Because, when eating, people's gastrointestinal organs will secrete digestive juice conditioned reflex, such as saliva secreted by the mouth when teeth chew food, digestive juice secreted by the stomach containing gastric acid and pepsin, etc. , mixed with food scraps. In this way, most nutrients in food are digested into substances that are easily absorbed by the human body. If you drink tea before, during and after meals, it will dilute saliva and gastric juice, weaken the activity of protease, affect digestion and absorption, and be unhealthy for a long time. It will dilute the digestive juice, which is not good for food. In addition, drinking too much water after meals will increase the burden on the kidneys and heart. Therefore, it is not advisable to drink water when eating.
(5) Do you often eat midnight snack?
Often choose 19 people, accounting for 19% of the total number, and occasionally choose 8 1 person, accounting for 8 1% of the total number.
Most students choose occasionally. We'd better eat less midnight snack, because food stays in the stomach for a long time after dinner, which can promote the secretion of gastric juice and stimulate the gastric mucosa for a long time. Over time, it will lead to gastric mucosal erosion, ulcer and weakened resistance. If the food contains carcinogens, such as fried, roasted, fried and other foods, it is more likely to have adverse effects on gastric mucosa and lead to gastric cancer if it stays in the stomach for a long time.
(6) Do you have the habit of eating breakfast?
There are 67 people who choose the part, accounting for 67% of the total, 27 people who choose according to the situation, accounting for 27% of the total, and 6 people who choose not to choose, accounting for 6% of the total.
Most students choose to have breakfast occasionally. Every morning is an important stage of mental and physical labor, which requires the brain to get excited as soon as possible, and breakfast is to start the brain? Switch? . After a night's deep sleep, the stored glucose in the body has been exhausted, and hormone secretion has entered a trough. The brain has no rice to cook, and the memory function tissue has to temporarily enter a frozen state. Breakfast is like giving charcoal in the snow, which can make hormone secretion reach a climax quickly and provide hungry brain cells with eager energy, just like thawing? Power switch? In this way, breakfast connects the brain with the current needed for activities in time. It can be seen that breakfast must not be perfunctory and postponed at will, and it is even more important not to eat breakfast. Long-term skipping breakfast will lead to unbalanced nutrition and low resistance. Not eating breakfast for a long time will not only lead to insufficient energy and nutrition intake for a whole day, but also lead to hunger at 90 o'clock in the morning, which will cause excessive friction on the inner wall of the intestine, damage the intestinal mucosa, lead to diseases and malnutrition of the digestive system, reduce the whole body immunity and greatly reduce the body resistance. Therefore, I hope students can develop the good habit of eating breakfast every day.
(2) Dietary structure
(1) Do you pay attention to the collocation of meat and vegetables?
165438+ 0% of the total, 67% of the total and 28% of the total.
With the popularity of vegetarianism, more and more people choose to live on vegetarianism. Drinking vegetarian food for a long time can prolong life, lose weight, reduce cholesterol content and reduce the chance of cancer, but it will cause gallstones and affect women's pregnancy, which is not conducive to hypertension and malnutrition. The most reasonable dietary structure is that the ratio of coarse grains to flour and rice is 6: 4; The ratio of vegetables to meat is 6: 4. Don't eat too many condiments: natural condiments such as pepper, cinnamon, clove and fennel are mutagenic and toxic to some extent.
(2) Do you deliberately go on a diet because of losing weight?
Those who choose the meeting account for 2 1% of the total, those who choose occasionally account for 58% of the total, and those who choose not account for 2 1% of the total. Among them, 67% of girls choose to go on a diet deliberately.
Dieting to lose weight will reduce your physical strength, exercise and nutrients; It will also cause brain cell death, hair loss, osteoporosis, long-term cessation of menstruation, and induce gallstones. In the end, you definitely can't keep going, start eating more, and your weight will eventually rebound. Why? Because the metabolic rate of the human body will decrease with the decrease of diet, exercise and nutrients. Your body is very smart, so you should be prepared for famine. Like a hibernating bear, learn to adjust (reduce) the metabolic rate and tide over the difficulties. Therefore, even if we return to the same calorie intake before losing weight, the body fat storage will be more than in the past, just like the fat bear next autumn, because the metabolic rate has dropped.
Especially nowadays, girls will deliberately lose weight because they pursue a beautiful figure and dress in fashion. So they only eat vegetarian food, and some people even eat only vegetables or fruits. This will lead to the lack of essential amino acids, fatty acids, fat-soluble vitamins, vitamin B 12, carnitine and so on. The lack of these nutrients will make your skin dry, your muscles slack, your face pale, your hair fall off and your reaction slow. At the same time, the efficiency of lipid metabolism decreases, which further aggravates obesity. ? Lose weight for a month, aging for three years! ? It's really true!
(3) Do you regularly ration three meals a day?
Of the total, 65,438+09% is fixed quantitative, 20% is fixed quantitative, 65,438+09% is fixed quantitative and 42% is fixed quantitative.
Few students eat regularly and quantitatively, and most of them choose the time and number of meals at will, which has a bad influence on the digestion of gastric function. Changes in eating time and appetite will inevitably affect the human body? Biological clock? Regularity, leading to changes in blood sugar. Therefore, we need to strengthen regular and quantitative eating habits.
General meal arrangement and calorie distribution
Breakfast, lunch and dinner.
7: 307: 3012: 0012: 3018: 0018: 30.
The ratio/%of daily total heat is 25 ~ 304030 ~ 35.
(4) Do you often use instant noodles instead of dinner?
Frequently choose 5 1% of the total, occasionally choose 16% of the total, rarely choose 25% of the total, and never choose 18% of the total. Boys, in particular, regard convenience food as a part of dinner.
Instant noodles are a kind of food that many college students like. It can be used as snacks, snacks and dinner. It is very convenient to eat and seems to be very popular with us. Especially many boys, they are not as worried about their bodies as women, and they are also very careless about their diet. Instant noodles are their "favorite" and they often put several bags in the bedroom. Most varieties of instant noodles are fried, and the oil is oxidized into oxidized lipid. It accumulates in blood vessels or other organs, forming aging phenomenon, accelerating people's aging speed, causing arteriosclerosis, and easily leading to diseases such as cerebral hemorrhage, heart disease and kidney disease. If it is used to replace staple food for a long time without adding any other food, it will easily lead to nutritional deficiency of human body, which is extremely unfavorable to health.
(3) Food hygiene
(1) Do you bring your own tableware when you eat?
8% of the total are frequent, 42% are occasional and 50% are never.
Most students don't bring their own tableware when they eat. However, your own tableware can make you feel at ease, make food hygiene safer, and make you feel at ease. In this way, it is possible to choose to use disposable tableware when eating, which will cause environmental pollution and the destruction and waste of resources. Eating with tableware can not only make personal food hygiene more reliable, but also protect the environment and save resources.
Do you wash your hands before meals?
Frequent selection accounts for 40% of the total, occasionally accounts for 50% of the total, and never accounts for 10% of the total. Don't wash your hands before eating. Usually, those bacteria and dirty things will follow into your body, causing stomach pain and serious roundworms.
(3) What do you think of roadside stalls?
Choice? Everyone can eat it. No problem. 365438+ 0% of the total, select? Like roadside stalls, often eat? 65438+ 03% of the total, choose? Feel unsanitary and seldom eat? 46% of the total, choose? Strongly opposed to roadside stalls? 10% of the total.
Food such as roadside barbecue contains a lot of carcinogens such as bacteria and nitrite. Some roadside stalls use expired raw materials, even raw water, and some inedible chemical raw materials such as chemical pigments and saccharin. Students with poor resistance can lead to bacillary dysentery and enteritis, and the consequences are more serious, such as heavy metal poisoning.
A Case Study of verb (abbreviation of verb)
(1) Statement of the case
Xiao Wang is a fat boy student. Because of his relatively superior family conditions, he gave little consideration to food consumption. He likes fried food, sweets, hamburgers and high-sugar drinks, and often has meals outside of dinner, especially supper. His snacks are almost the same as his normal meals. He seldom chooses vegetarian dishes for dinner. Every meal of breakfast, lunch and dinner must have meat and staple food. Because of mood, stress and other factors, he often overeats. Because of his strong desire for food, he paid little attention to food hygiene. Although he is fat, he still likes sports. After exercise, he will feel exhausted, so he often eats immediately and eats much more than usual.
(B) Case analysis
(1) In terms of diet structure, his dinner diet structure is too simple, characterized by high calories and high fat. This can easily lead to excess calories but malnutrition, and in severe cases obesity and a series of complications, such as diabetes and fat.
