Three investigation reports on diet health

The purpose of diet health education is to improve students' diet structure, improve their concept of healthy diet, strengthen their physique, reduce diseases caused by wrong diet, and lay a solid foundation for students to learn scientific knowledge. The following is a survey report on diet health that I carefully arranged for you, hoping to help you!

Investigation report on dietary health 1

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 and drink 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 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.

Investigation Report on Dietary Health (Ⅱ)

With the rapid development of science and technology, our life has been greatly improved. And in daily life, what is the most important thing? Eat? What you eat is food. Indeed, food is indispensable in our life. Recently, the food we eat is getting better and better, but how much of the delicious food is unhealthy? How many people skip eating three meals a day because of junk food? With these two questions, I made a survey of the students in our senior high school.

1. According to the survey, 10% people don't eat breakfast, 27% people eat breakfast occasionally, and 40% people buy some 0.5 yuan -2 yuan food for breakfast in roadside shops or breakfast shops, and these foods are so-called junk food. 13% people buy bottled instant noodles for breakfast in small shops. From the nutritional point of view, instant noodles are single in nutrition, and long-term consumption is not conducive to children's growth and development, and will bring harm to health. The data show that 60% of people who eat instant noodles for a long time are malnourished, 54% are iron-deficiency anemia, 23% are riboflavin deficient, 16% are zinc deficient, and 2% suffer from various eye diseases due to vitamin A deficiency. In addition, people who like to eat instant noodles often have symptoms such as sores, dry stools and dry skin. The convenience of the barrel is more harmful to human body, and the barrel used for instant noodles is disposable foamed plastic, which seriously harms people's health. Experts pointed out that these disposable foamed plastic tableware not only seriously pollute the environment, but also cause damage to people's liver, kidney, reproductive system and central nervous system if the temperature reaches above 65 degrees Celsius when brewed with boiling water. As the saying goes? Eat well early, eat well at noon and eat less at night? . Skipping breakfast can lead to memory loss, depression and inattention.

Second, fried food such as barbecue is also their favorite. Every evening, the busy places in the village will be crowded with people around the barbecue car. Barbecue has won the favor of teenagers with its unique taste, but there are a lot of parasites in barbecue. If it is not cooked thoroughly when baking, it won't kill the egg. Eggs enter the body, attach to the intestinal wall, and then enter the blood. With the flow of blood, eggs will slowly grow and reproduce in the human brain or other parts of the body.

Fried food is not good either;

(1) Hygiene is not up to standard.

(2) It will lead to obesity.

(3) It will produce harmful and toxic substances.

(4) The nutrients are severely damaged.

(5) The aluminum content seriously exceeds the standard.

(6) It is easy to cause diseases. Therefore, we should stay away from barbecue fried food. Third, the nutrition needed by teenagers' physical development is closely related to green and healthy food. Teenagers are growing sturdily, and food nutrition is the material basis for promoting healthy development. Not only should they reasonably match their diet to meet their nutritional needs, but they should also correct their bad eating habits, so that they can completely stay away from unhealthy food, form a good habit of eating breakfast, eat more cereal and supply enough energy. Ensure the intake of fish, meat, eggs, milk, beans, vegetables and fruits. Avoid overeating, picky eaters and blind dieting, eat less snacks and develop good eating hygiene habits.

Investigation report on diet health (3)

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. 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.
