The investigation report on dietary health 1
I. Introduction
In recent years, our government has been paying more and more attention to the promotion of nutritional diet of the residents of the scientific. College students are the pillars of the country, its nutritional improvement and dietary structure of the correct adjustment, directly related to the improvement of college students' physical fitness, but now many college students due to poor knowledge of diet and nutrition or poor dietary attitudes caused by a series of health problems. In order to further explore the problems in the diet of college students, and then optimize the dietary structure, improve dietary habits, pay attention to dietary hygiene, my research group for my campus students to carry out research work in the diet.
Second, the investigation of the relevant description
(a) the purpose of the investigation
Through the understanding of the dietary status of college students, the outstanding problems of further discussion, proposed solutions to enable college students to have a better and more scientific dietary habits.
(II) Survey Methods
We conducted a survey on our students entitled ? College students dietary health questionnaire? Sample survey, issued 100 copies of the questionnaire, 100 copies of the recovery, the efficiency rate of 100%, the survey popularization of each department, can truly reflect the contemporary college students in the dietary health situation.
(C) survey time
October 5 to December 15
(D) the scope of the survey
Chengdu Teachers College Wenjiang campus of freshmen and sophomores
Fourth, the survey questionnaire analysis
(a) dietary habits
(1) Do you binge eat?
21% of the total number of students chose often, 58% of the total number of students chose occasionally, and 21% of the total number of students chose never
Most students chose occasionally. You should not overeat, as the saying goes. If you want to be in good health, you should not eat too much. Overeating can not only destroy the digestion and absorption function of the gastrointestinal tract, causing acute gastroenteritis, acute gastric dilatation and acute pancreatitis, and due to the rise of septum, affecting cardiac activity, but also induced heart disease, etc., and if the rescue is not in time, it will be life-threatening. Therefore, do not eat, drink and overeat at any time. (2) Do you have the habit of drinking water in the morning?
The number of people who chose yes was 65, accounting for 65% of the total, and the number of people who chose no was 35, accounting for 35% of the total.
Most students chose yes. This is a good eating habit. Drink a cup of cool boiled water after getting up in the morning, which is conducive to liver and kidney metabolism and lower blood pressure to prevent myocardial infarction, some people call it ? Resurrection water? Scholars believe that after a few hours of sleep, the digestive tract has been emptied, drink a cup of cool water in the morning, can be quickly absorbed into the blood circulation, dilute the blood, so that the organs of the body for a? The first thing you need to do is to get rid of all the stuff that's in your body.
(3) Do you have the habit of picking your food?
There were 34 people who chose yes, accounting for 34% of the total, and 66 people who chose no, accounting for 66% of the total.
Most of the students are not picky eaters and partiality, such eating habits help the body grow healthily. Because the nutrients that the human body needs are supplied by a variety of foods, there is no one natural food that can contain all the nutrients that the human body needs. Eat a single food; no matter how much to eat, how rich in nutrients, but also can not maintain the health of the human body. Therefore, in the diet, not long-term picky or partiality.
(4) Do you drink water or beverages while dining?
The number of people who chose often was 25, accounting for 25% of the total, the number of people who chose occasionally was 53, accounting for 53% of the total, and the number of people who chose never was 19, accounting for 19% of the total.
Most students chose occasionally. It is best not to drink water or beverages while eating. Because, the human stomach and intestines and other organs, to eat, will reflexively secrete digestive juices, such as teeth in chewing food, oral secretion of saliva, stomach secretion containing gastric acid, pepsin digestive juices, etc., mixed with the food crumbles, so that most of the nutrients in the food, it is digested into the substances that can be easily absorbed by the body. If you drink tea and water before, during or after meals, it is bound to dilute and dilute the saliva and gastric juice, and make the enzyme protease enzyme is weakened, affecting the digestion and absorption, when long will make the body in poor health. Will dilute the digestive juices, is not conducive to 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 during meals.
(5) Do you often eat late-night snacks?
There were 19 people who chose often, accounting for 19% of the total, and 81 people who chose occasionally, accounting for 81% of the total.
Most students chose occasionally. We'd better eat less late-night snacks, because after eating late-night snacks and then sleep, the food stays in the stomach for a longer period of time, which can promote a large amount of secretion of gastric juice, causing prolonged stimulation of the gastric mucosa, which, over time, leads to gastric mucosal erosion, ulceration, and weakening of the resistance. If the food contains carcinogenic substances, such as deep-fried, barbecued, fried food, long stay in the stomach, it is more likely to cause adverse effects on the gastric mucosa, which in turn leads to gastric cancer.
(6) Do you have the habit of eating breakfast?
There are 67 people who choose to have it, accounting for 67% of the total, 27 people who choose to depend on the situation, accounting for 27% of the total, and 6 people who choose not to have it, accounting for 6% of the total.
Most students chose to eat breakfast occasionally. Every morning is an important stage of human mental and physical labor, very much in need of the brain to get excited as early as possible, and breakfast is to start the brain? switch? Body reserves of glucose after a night's sleep has been consumed, hormone secretion has entered the trough, the brain is difficult to cook without rice, memory function organization had to temporarily enter the frozen state. Breakfast, as if in the snow to send charcoal, can make hormone secretion soon into the climax, and to the ow to feed the brain cells to provide the desire to get the energy, as if thawing the? Power switch? , breakfast is so timely to the brain activity required to connect the current. It can be seen that breakfast is absolutely not perfunctory and arbitrary postponement, not to mention not eating breakfast. Long-term do not eat breakfast will lead to nutritional imbalance, low resistance, long-term do not eat breakfast will not only cause a full day of energy and nutrient intake is insufficient, but also, generally to the morning of the nine or ten o'clock there will be the phenomenon of hunger, resulting in excessive friction of intestinal lining, damage to the intestinal mucosa, leading to digestive disorders caused by malnutrition, so that the whole body of the immune system to reduce the body's resistance will be greatly reduced. Therefore, I hope that students will develop a good habit of eating breakfast every day.
(2) Dietary structure
(1) Do you pay attention to the combination of meat and vegetables
11% of the total number of people who chose meat as the main, 67% of the total number of people who chose vegetarianism as the main, and 28% of the total number of people who chose a relatively balanced
With the popularity of vegetarianism, more and more people choose to live on a vegetarian diet. Long-term consumption of vegetarian food, although it can benefit life and longevity, lower body weight, lower cholesterol levels, reduce the chances of cancer, but it can cause gallstones, affect women's pregnancy, is not conducive to the lowering of high blood pressure in hypertensive people, malnutrition. The most reasonable dietary structure for the proportion of coarse grains and fine grains is 6:4 ;the proportion of vegetables and meat is 6:4. Do not eat too much seasoning: pepper, cinnamon, cloves, cumin and other natural seasonings have a certain mutagenicity and toxicity.
(2) Do you intentionally diet to lose weight
21% of the total chose yes, 58% chose occasionally, and 21% chose no. The girls chose to deliberately diet to lose weight
(3) Do you intentionally diet to lose weight
(4) Do you intentionally diet to lose weight
(5) Do you intentionally diet to lose weight? And among them, 67% of the girls chose that they would deliberately diet
Dieting to lose weight will make you lose physical strength, exercise and nutrients; long time will also cause brain cell death, hair loss, osteoporosis and menstruation stops, as well as inducing gallstones and other serious consequences. Later on you will definitely not be able to stick to it and start eating more, and your weight will eventually rebound and super rebound. Why? Because the body's metabolic rate drops with the amount of food, exercise and nutrients you eat. Your body is smart enough to prepare for the battle and prepare for the famine, like a hibernating bear, and learns to regulate (lower) the metabolic rate to get through the hard times. And so, even when reverting to the same caloric intake as before the weight loss, there will be more body fat stored than in the past, like a fat bear the following fall, because the metabolic rate has dropped.
Especially nowadays, girls will go for the pursuit of a beautiful body, wear fashionable clothes, and deliberately lose weight. Thus, they only eat vegetarian food, and some even eat only vegetables or fruits. This will cause a lack of essential amino acids, fatty acids, fat-soluble vitamins, vitamin B12 and carnitine. The lack of these nutrients will make your skin dry, muscle relaxation, pale, hair loss, slow reaction; at the same time lipid metabolism efficiency decreased, thus further increasing obesity. Lose weight in January, aging three years! The first thing you need to do is to get your hands on a new pair of shoes or boots. This has a negative impact on the digestion of the stomach. The change of meal time and meal quantity will definitely affect the human body's biological clock. Biological Clock and lead to changes in blood glucose. Therefore, we need to strengthen the regularity of eating habits.

(4) How often do you replace your regular meals with instant noodles
Those who chose often accounted for 51% of the total, those who chose occasionally accounted for 16% of the total, those who chose rarely accounted for 25% of the total, and those who chose never accounted for 18% of the total. Boys, in particular, eat convenience foods as part of their regular meals.
Instant noodles are a favorite food of many college students, it can be used as a snack, snack, and as a regular meal, and easy to eat, it seems to be very us. Especially a lot of men, not as many as women for the body of the concerns, but also on the diet of sloppy, instant noodles is their "favorite", often in the dormitory put on a few packs. Most varieties of instant noodles are fried in oil, and the oil is oxidized into oxidized lipids. It accumulates in the blood vessels or other organs, the formation of aging phenomenon, accelerate the speed of aging, cause atherosclerosis, easy to lead to cerebral hemorrhage, heart disease, kidney disease and other diseases. If long-term used to replace the staple food, without adding any other food, it is easy to lead to human nutritional deficiencies, extremely unfavorable to health.
Investigation report on dietary health 2
With the ever-changing technological changes, our lives have greatly improved. And in daily life, the most important thing is? Eat? , eating is also food. Indeed, food is essential in our lives. Recently, the food we eat has become better and better, but how much of the delicious food is unhealthy? And how many people skip three meals a day because of junk food? With these two questions, I do a survey of our high school students.
First, according to the survey, 10% of the people do not eat breakfast, 27% of the people occasionally eat a breakfast, 40% of the people on the roadside store or breakfast store to buy some 0.5 yuan -2 yuan of food as breakfast to eat, and these foods are the so-called junk food. Thirteen percent of the people buy buckets of instant noodles at small stores as breakfast. From a nutritional point of view, instant noodles are single-nutritional and long-term consumption is not conducive to the growth and development of children and will bring harm to health. Data show that 60% of people who consume instant noodles for a long time are malnourished, 54% suffer from iron deficiency anemia, 23% suffer from riboflavin deficiency, 16% suffer from zinc deficiency, and 2% suffer from various eye diseases due to vitamin A deficiency. In addition, people who like to eat instant noodles, the occurrence of sores on the corners of the mouth, dry stools, dry skin and other symptoms are more people. The barrel of instant noodles to the human body is more harmful, loaded with instant noodles barrel is made of disposable styrofoam, seriously jeopardizing people's health. Experts pointed out that these disposable foaming plastic tableware not only in serious pollution of the environment, but also with boiling water, if the temperature reaches 65 degrees Celsius or more, its harmful substances will penetrate into the food, thus causing damage to the human liver, kidneys, reproductive system, central nervous system. As the saying goes? Eat well in the morning, eat enough in the afternoon, and eat less in the evening? Breakfast is not eaten will lead to memory decline, emotional depression mental inattention and so on.
Second, barbecue and other fried food is also their favorite, every evening when the village of the busy place barbecue car around will be crowded with people. Barbecue with a unique flavor to win the favor of teenagers, but the barbecue has a large number of parasites, if not thoroughly cooked in the turning grill, can not kill the eggs, the eggs into the body, attached to the intestinal wall, and then will enter the bloodstream, with the flow of blood, the eggs will be in the human brain or other parts of the body to slowly grow and multiply.
Fried food is also bad:
(1) Hygiene is not up to standard.
(2) It can lead to obesity.
(3) Can produce harmful toxic substances.
(4) Nutrients are severely damaged.
(5) Serious excess of aluminum.
(6) Easily cause disease. Therefore, we have to stay away from barbecue fried food. Third, the physical development of young people's nutrition and green health food is closely related to the physical development of young people are exuberant growth and development, food nutrition is to promote healthy development of the material basis, we not only want to reasonably match the meals to meet their nutritional needs, but also to correct their bad eating habits, to completely let them away from unhealthy food, to form a good habit of eating breakfast, eat more cereals, the supply of sufficient Energy. Ensure the intake of fish, meat, eggs, milk, beans and vegetables and fruits. Avoid overeating, picky eating and blind dieting, eat less snacks, and develop good dietary hygiene habits.
Investigation report on diet and health 3
With the social and economic development, people's living standards have been greatly improved, and health has become the goal of modern people. But some health problems are always testing and challenging our body, more and more attention to diet and health issues have become a problem plagued by modern people. However, it is understood that the most important factor leading to our unhealthy is diet, the poor diet of secondary school students will appear many health problems, for this reason our group chose? Diet and health? We investigated the issues related to diet and health among junior high school students. Among junior high school students, 10% of them often do not eat breakfast, 27% of them sometimes do not eat; 15% of them do not eat a reasonable amount of food in three meals. These are serious dietary unhealthy phenomena, through these phenomena, we can derive the causes of diet and health problems of junior high school students, so that the majority of secondary school students recognize the relationship between diet and health, so that he (she) know the correct diet to be healthy. First, first of all, not eating breakfast is extremely harmful.
1, the harm to the brain. Although the weight of brain tissue accounts for only 2-3% of a person's body weight, but the brain's blood flow is about 800 milliliters per minute, oxygen consumption is about 45 milliliters per minute, and sugar consumption is about 5 grams per hour. Teenagers' brain tissue is in the developmental stage, and the demand for blood, oxygen and glucose is higher than that of adults. If the blood sugar is too low, the brain conscious activity will be impaired, long-term, is bound to affect the weight of the brain and morphological development.
2, the harm to the digestive system. Under normal circumstances, the first night to eat food after six small or so from the stomach to empty into the intestinal tract. The next day if you do not eat breakfast, stomach acid and various digestive enzymes in the stomach will go? digest? the mucous membrane layer of the stomach. In the long run, the normal function of the cell secretion of mucus will be damaged, it is easy to cause gastric ulcers and duodenal ulcers and other digestive system diseases.
3, causing atherosclerosis and more likely to lead to obesity. There are many young students are afraid of fat and do not eat breakfast. This practice has no scientific reason. The human body on the calorie demand is a standard, do not eat breakfast, is bound to increase the amount of food in the dinner. After dinner is generally less exercise, more likely to cause fat accumulation and lead to obesity. In addition, long-term not eating breakfast will also make cholesterol, lipoprotein deposits in the inner wall of the blood vessels, resulting in vascular sclerosis.
4, make you slow: breakfast is the source of energy for brain activity, if you do not eat breakfast, the body can not supply enough blood sugar for consumption, you will feel tired, fatigue, brain power can not concentrate, mental retardation, slow reaction.
5, chronic diseases may? The first thing that you need to do is to get a good deal on your own. Body: do not eat breakfast, hungry to start the day's work, the body in order to get power, will use the thyroid, parathyroid, pituitary gland and other glands, to burn tissue, in addition to causing glandular hyperactivity, but also make the body acidic, suffering from chronic diseases.
6, the stomach and intestines may want to? The first time I saw this is when I was a kid, and I was a kid, and I was a kid.
7, constipation? The first thing you need to do is to get out of the cage. : In the case of three regular meals, the body will naturally produce gastrointestinal reflex phenomenon, simply to promote defecation; if you do not eat breakfast into the habit, long-term may cause gastrointestinal reflex dysfunction, and then produce constipation.
8, will make you closer to the obese: the human body once the realization of nutritional deficiencies, the first consumption of carbohydrates and proteins, the last consumption of fat, so do not think that do not eat breakfast will contribute to the consumption of fat. On the contrary, do not eat breakfast, but also make lunch and dinner to eat more, slimming is not but more fat.
Nutritionists have confirmed that breakfast is the least likely to be converted into a fat meal for everyone in the day. If you don't eat breakfast every day, you will only eat more for lunch.
Secondly, the ratio of breakfast, lunch and dinner should be 3:4:3, so that the essence of what you eat in a day can be consumed in the most energetic time.
On the diet:
21% of the people intake of fat, oil, desserts in excess;
20% of the people intake of dairy products in excess;
13% of the people intake of high-protein food in excess;
18% of the people intake of vegetables is not enough;
36% of the people intake of fruits in insufficient;
22% of the people don't consume enough cereals;
11% don't have enough nutrients in their diet;
and only 12% barely meet a healthy dietary pagoda.
In summary, the dietary situation of junior high school students is not optimistic. In addition to investigating their dietary behaviors, we also meticulously investigated their dietary awareness:
Only about 1∕5 of them have a strong concept of healthy diet;
and more than 1∕2 of them don't pay enough attention to it;
C. Overall, the students' concepts of healthy diets are relatively thin Do
Spring more acidic foods, such as foods containing vitamin C and organic acid fruits, as well as sugar and vinegar and sour and spicy dishes. Scientific research has found that these sour foods contain a certain substance that can exponentially improve the absorption of inorganic salts such as calcium, iron and zinc.
Eat more acidic foods in the spring, such as foods containing vitamin C and organic acid fruits, as well as sweet and sour vinegar and spicy dishes. Scientific research has found that these acidic foods contain a certain substance that can multiply the absorption rate of inorganic salts such as calcium, iron and zinc.
In summer, the weather is hot, and bitter foods, such as bitter melon and oatmeal, have the effect of clearing heat, moderate intake of such food is beneficial to the body.
In the fall, the climate is dry, the weather turns cool, is the time to nourish the lungs, can be added to the diet of spicy foods, such as ginger, garlic, etc., can improve immunity, can enhance blood circulation.
The cold weather in winter, is water, is a good opportunity to nourish the kidneys, therefore, at this time, you should eat more flavored black food, such as fungus, black beans, sesame seeds and so on.
Breakfast must be eaten, which is essential every morning. Try not to eat greasy food, too much greasy food in the morning, such as doughnuts, oil cake, chocolate, hamburgers, etc., the morning is easy to be sleepy, poor concentration, after deep-fried flour, such as doughnuts, which will also lose the nutrients.
Do not go to bed immediately after meals. This will slowly reduce the oxygen supply to the brain, easy to cause heartburn and indigestion, but also fat, you should stand half an hour in bed, this time you can do appropriate chores, such as: dishwashing, mopping, etc.
Sitting without stilts. Because this will make the leg blood flow is not smooth, affecting the health of the body. Drink more sour milk, which has more nutrients than milk, more helpful for digestion and absorption. It has a certain function of disease prevention and health care
Don't overeat, don't eat, exercise more, and stick to a reasonable meal every day. Adolescent physical development is extremely rapid, coupled with intense study, activity, so you need to intake more calories. Calories mainly come from staple food rice, noodles and fat, protein, so secondary school students should first eat three meals. Secondary school students metabolism is vigorous, bone growth fast, the number of muscle tissue cells straight up, to pay special attention to calcium, phosphorus, magnesium and vitamin A, D supply. The formation of a large number of tissues need iron, insufficient supply can occur anemia, so iron supplementation is more important. To abandon the habit of picking and choosing food, a reasonable mix of food and vegetables, meat and vegetables, not only can make the body needs a full range of nutrients, each other complementary (i.e., nutritional complementary role) in addition to pay attention to the above points of the diet of secondary school students should also take into account the characteristics of the period: in the dietary habits, it is easy to eat uncontrolled, overeating, eating, avoiding, picky, snacking, and dieting and fear of fat and so on. They should be helped to change such bad habits.
Family meals should be enough quality, the menu should be diversified, the daily supply of meat and eggs meat 100-150 grams, 1 bottle of milk or soymilk, 500-750 grams of grain, vegetables for 300-500 attention to replenish a variety of vitamins. Because high school students use their eyes a lot, vitamin A supply is sufficient to help protect eyesight, but also to prevent respiratory infections; vitamin B is related to the body's energy consumption; vitamin C can promote the absorption of iron. The cold season should also consider vitamin D supplementation to improve the absorption of calcium.
In summary, we recognize the relationship between diet and health: to get the answer to the question of why does it appear? Diet and health of secondary school students? The answer to the question; know how to diet for secondary school students to be healthy, the results of our investigation has reached the purpose of our topic.
