(l) Teenagers with thermal energy grow fast, have a large amount of activities and need more thermal energy, with an average of about 2,800 calories per day.
(2) Teenagers in protein need more protein than adults, and the quality is also higher than adults. They need about 80-90 grams of protein every day. Teenagers should eat more animal protein, such as eggs, milk, lean meat and animal liver. In addition, animal protein should also be distributed in three meals, not concentrated in one meal, so as not to increase the burden on the gastrointestinal tract.
(3) Vitamins are indispensable substances for human growth and development, especially for teenagers. If you lack vitamins for a long time, it will affect your growth and even lead to vitamin deficiency. If vitamin A is deficient, you will suffer from night blindness.
Symptoms, dry eye; Vitamin b; Lack, will suffer from neuritis, beriberi; Vitamin B2 deficiency. Will suffer from angular stomatitis and glossitis; Vitamin c deficiency can lead to scurvy; Vitamin D deficiency will affect its bone development. To this end, teenagers had better eat 500 grams of fresh vegetables every day.
(4) Inorganic salt teenagers need to have enough elements such as calcium, phosphorus, iron and iodine. Calcium and phosphorus are the main substances that make up bone canals and teeth. Without calcium and phosphorus, the development of bone canal will be hindered, and rickets will occur in severe cases. Iron is an important component of red blood cells. With the growth of the body, the blood volume of teenagers increases gradually and needs more iron. If they lack iron, they are prone to anemia. Iodine is an important component of thyroxine, which can promote metabolism and the development of nerve-bone pathway. Teenagers with insufficient iodine intake will be short stature and mentally retarded.
2. What little knowledge do you have about the health of middle school students?
From primary school to middle school, this is not only a great turning point in one's learning process, but also means the arrival of an important physiological development stage. From the age of twelve or thirteen (girls are one or two years earlier than boys), the human body enters a leap period of growth and development-adolescence. For most people, this is just the beginning of middle school life. During adolescence, various organs of the human body generally accelerate their growth and gradually reach a mature level.
During this period, the growth of height can be increased from 4~6 cm a year to 8~ 10 cm. The body weight increased from 1.5 ~ 2kg per year to 5 ~ 6kg, and the growth rate of internal organs was greatly accelerated. Such as the heart, in adolescence, the body weight can be increased to 10~ 12 times of that at birth. It can be said that the middle school period 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, the study is tense, the activity is large, and more calories are needed.
The calories mainly come from rice, flour, fat and protein, so middle school students should eat three meals first. Eat more fish, lean meat, eggs, milk, bean products and other rich foods in protein. The daily supply of protein is about 80 ~ 90g. Adequate vitamins and minerals should be supplemented. Teenagers' 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, especially for girls who lose a certain amount of blood every time because of menstrual cramps, so iron supplementation is more important. In addition, with the strengthening of thyroid function, more iodine is needed; Both physical development and the gradual maturity of sexual organs need zinc; Maintaining normal metabolism, growth and development is inseparable from the supply of adequate vitamins. Some middle school students have the habit of being partial to food and picky about food. They like to eat this kind, but don't like that kind, or they only eat a few kinds and don't eat anything else, especially vegetables, which will lead to unbalanced nutrition. For example, eating meat instead of vegetables can easily lead to the lack of vitamins and minerals, laying a "time bomb" for suffering from hyperlipidemia and cardiovascular diseases in adulthood. Therefore, it is necessary to develop good eating habits from an early age to ensure a balanced mix of various nutrients.
It is especially important to have a good breakfast. The intense study and activities in the morning require that breakfast must contain enough calories. Some students ate a little in the morning and then hurried to school. After two classes, their stomachs were empty. In the third and fourth class, there will be listlessness and inattention, which will affect normal study. Therefore, we should pay special attention to breakfast, which accounts for 1/3 of the total calories in a day. Some nutritious eggs, milk, peanuts, soybeans and so on. Can be added, when conditions permit, you can add meals to ensure students' energetic study.
Adolescence is the golden age of intellectual and physical investment. Only by keeping the "weather" well can we grow well, be strong, think quickly and grow healthily.
3. Nutrition and health of middle school students
Report on Nutrition and Health of Middle School Students Author: Anonymous article Source: ClickNo.: 1696 Update Time: June 25, 2009 Project Team Leader-Wang Lu Gender-Female Project Type-Small Paper Large Class-Small Class-200706C3 Collaborators-Dani, Jiang Yue, Li, Zhou, Tutor-The project involves related disciplines-Bio-political topics.
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.
Project conditions-we can interview classmates at school and get information; Through on-the-spot investigation, we understand the research purpose of students' nutrition and health problems such as diet-middle school students are in the stage of growth and development, with strong metabolism, and the amount of energy and various nutrients needed is relatively higher than that of adults. And if the nutrition is not balanced, it will affect the normal growth and development.
With the development of economy and the continuous improvement of people's living standards, there are some unhealthy phenomena in middle school students' diet: picky eaters, overeating, partial eclipse, dieting and so on. Through investigation, it is found that students know little about what food to eat and what nutrition to supplement, which leads to malnutrition and reduced learning efficiency.
The main research methods-1,questionnaire method 2, data consulting method 3, and the basic idea of action research method-1combine data investigation with field observation, and the scientific, advanced and practical research of two team members-through understanding the nutrition and health that middle school students need, students can better absorb the needed nutrition. The basic process of the research on healthier study and life-1 ~ 2 weeks of preparation1. Determine topic 2. Divide the work into three groups. The research and implementation of the questionnaire for 2~3 weeks 1. Send and receive questionnaires. Conduct observation, analysis and interviews. Collect information online and ask the teacher to help show the results of the third stage in 3~4 weeks. 8+0. Write the findings and suggestions. 2. Organize the research results, the main contribution of members in the project-complete the project report, complete the project opening report in time and in detail, and enter the research stage as soon as possible. Main person in charge: everyone will carry out the project opening demonstration and strive for the grade opening demonstration. Main person in charge: Wang Lu searched for information to learn more about the project. Principal: Jiang Yue Action Research Method. The main person in charge who knows the situation: Li and Zhou. Principal in charge of forensic statistics: Dani. Conclusion The main person in charge: Everyone completes the whole research experience-a reasonable and nutritious diet is of great significance to the healthy growth and study of teenagers. Maybe you will find various excuses, such as: "I am too busy studying;" Just eat enough; See how strong I am, do I still need it? " In fact, I used to think so, only after I learned about the research study of middle school students' nutrition and health. Actually, it's not. Middle school is the growth and development period of teenagers' bodies. However, due to the pressure and tension of middle school study, we don't pay much attention to our health, but it is very bad. ——Dani This time we are studying the nutrition and health of middle school students.
Middle school students are in adolescence and have special nutritional needs. Adolescence is a vigorous period of human growth and development, and of course it needs extra nutrition. So pay attention to the absorption of nutrients.
Due to intense study and much homework, many middle school students often simply cope with breakfast without paying attention to the reasonable collocation of meals, which leads to physical underdevelopment, fatigue, emaciation, decreased resistance and even some diseases. Food is rich in nutrients, so the absorption of meals is the main source of our energy.
After research, I have gained a lot. In the developmental stage, we should take good care of our nutrition in order to develop healthily. In the fierce competition of modern society, everything is very important. Through investigation and study, we have exercised our practical ability, and the skills of communicating with others have given us a lesson in dealing with interpersonal relationships in advance in the future, and also cultivated our innovative consciousness and spirit.
-Jiangyue Middle School is the most important and favorable period to acquire knowledge, health and physical fitness. 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. Eating a good breakfast is very important, because children have to study for 4~5 hours in a row in the morning, and they also have recess activities, which consume a lot of energy and various nutrients.
If you don't eat breakfast or eat it badly, it will have a negative impact on your study and health. In the last two classes, you will have hypoglycemia reactions such as hunger, dizziness, inattention and palpitation, which unfairly affects your study and harms your health. So, be sure to have a good breakfast. Breakfast energy should account for 30% of the total energy of the whole day.
As the main meal of the day, the main and non-staple foods of lunch should be rich and varied. 15-year-old students are generally required to eat 50 grams of lean meat, 50- 100 grams of bean products and 250 grams of vegetables, and it is best to eat fish 2-3 times a week. The staple food depends on the amount of food eaten. Dinner energy should account for 30%-35% of the total energy of the whole day, which is basically the same as lunch.
-Li Hezhou's research study is of great significance to us. Not only to get credits, but more importantly, we know that cooperative learning is conducive to enhancing the feelings between teammates and has a positive effect on cultivating teams.
I have exercised my ability and cooperation with my classmates. We have learned a lot, not only have a deeper understanding, but also have a certain improvement in various practical activities.
At the same time, we know that unity cannot be ignored. The comprehensive practice course has benefited us a lot, and we all need to do our part to finish the work.
Research study. Yes
4. Tips for healthy eating
It has something to do with diet. Send a few words: eat whole grains, vegetables, colorful soups, seaweed soups, meat, less oil in legs, less oil, less salt and more water. It is very difficult to achieve the above six items. Except for retired people who have time to rest at home (it is very late), people have no time to care about their diet during work. The incubation period of "three highs" (hypertension, hyperlipidemia and hyperglycemia) is just when they are young. It is suggested that you overcome your appetite for food, balance nutrition and eat oil in moderation, especially edible oil. Be sure to eat edible oil (di-sub-oil) containing two essential fatty acids (linoleic acid and α -linolenic acid) in a proper proportion. The edible oil on the market basically contains a single essential fatty acid or the proportion is basically unreasonable. Recently, I saw that Zhalangzi Shuangya edible oil should be a good oil. It is a combination of safflower seed oil and linseed oil, which overcomes the shortcoming of single essential fatty acid in common edible oil.
5. As a middle school student, how to match the diet is healthy?
Hello! As a junior high school student, mental and physical labor are increasing, and the body is also in a stage of rapid development, which requires high nutrition. During this period, if the nutrition supply is insufficient, it will not only affect the normal growth and development of the body, but also lead to emaciation, anemia, fatigue, decreased vision, decreased memory and infection due to decreased resistance. Therefore, the reasonable arrangement of middle school students' diet is very important.
Attention should be paid to when arranging diet:
(1) The heat must be sufficient. Middle school students need more calories than adults, and they should ensure enough staple food every day, generally reaching150-200g per meal. They can eat steamed bread, biscuits, rice, fried dough sticks, cakes, sesame sauce and so on. Non-staple food should also be added. You can eat 500g vegetables,100g meat,100g bean products, milk, eggs and fruits every day.
(2) Ensure sufficient supply of high-quality protein. 50% of protein should come from animal protein or bean products, so as to meet the needs of accelerating growth and intellectual development and improve disease resistance. Foods rich in high-quality protein include lean meat, fish, milk, eggs and bean products.
(3) Calcium, iron, iodine, zinc and other elements should be supplemented. These elements are most needed and most easily lacking by middle school students in adolescence. The human skeleton is mainly composed of calcium and phosphorus. Middle school students need a lot of calcium and phosphorus to supplement in the process of rapid growth. They should choose more vegetables, beans, seafood and milk containing calcium and phosphorus, and drink a glass of milk or soybean milk every day to get more calcium and protein. Adolescence is the most prone to anemia in a person's life, and anemia is mainly caused by iron deficiency. So eat more foods rich in iron and vitamin C, such as lean meat, eggs, liver, fish, vegetables and fruits. The development of gonadal organs reaches its peak in adolescence. Iodine is also an essential trace element for growth and development. Generally, seafood, animal offal and meat are rich in iodine and zinc and can be eaten frequently.
(4) Pay attention to supplementing 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. In addition to the above points, the diet of middle school students should also consider the characteristics of this period:
(1) Teenagers like to act together, imitate each other, and often influence each other in their eating habits. They are prone to overeating, overeating, partial eclipse, taboo, picky eaters, love snacks and dieting, and are afraid of being fat. Therefore, we should help them get rid of these bad habits.
(2) Most middle school students need to board in schools or residential areas, so we should pay attention to the management of collective diet, pay attention to dietary balance, and ensure adequate supply of nutrients.
(3) The family diet 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. When three meals are insufficient, snacks can be supplemented, and meat buns and cakes rich in energy and protein can be supplied, but it is not advisable to eat more snacks, such as candy and melon seeds.
Respondent: Kindness and beauty, follow benevolence and righteousness.
6. Give teenagers a book about life, diet and health.
Adolescence is the golden age of physical and intellectual growth in life.
During this period, all parts and organs of the whole body gradually mature. Growth rate, sexual maturity, learning ability and labor efficiency are closely related to nutritional status.
In order to make teenagers grow up healthily, we should pay attention to the following special requirements in diet: (l) Thermal energy Teenagers grow fast and have a large amount of activities, which requires more thermal energy, with an average of about 2,800 calories a day. (2) Teenagers in protein need more protein than adults, and the quality is also higher than adults. They need about 80-90 grams of protein every day.
Teenagers should eat more animal protein, such as eggs, milk, lean meat and animal liver. In addition, animal protein should also be distributed in three meals, not concentrated in one meal, so as not to increase the burden on the gastrointestinal tract.
(3) Vitamins are indispensable substances for human growth and development, especially for teenagers. If you lack vitamins for a long time, it will affect your growth and even lead to vitamin deficiency.
If vitamin A is deficient, you will suffer from night blindness and dry eye; Vitamin b; Lack, will suffer from neuritis, beriberi; Vitamin b2 deficiency. Will suffer from angular stomatitis and glossitis; Vitamin c deficiency can lead to scurvy; Vitamin D deficiency will affect its bone development.
To this end, teenagers had better eat 500 grams of fresh vegetables every day. (4) Inorganic salt teenagers need to have enough elements such as calcium, phosphorus, iron and iodine.
Calcium and phosphorus are the main substances that make up bone canals and teeth. Without calcium and phosphorus, the development of bone canal will be hindered, and rickets will occur in severe cases. Iron is an important component of red blood cells. With the growth of the body, the blood volume of teenagers increases gradually and needs more iron. If they lack iron, they are prone to anemia.
Iodine is an important component of thyroxine, which can promote metabolism and the development of nerve-bone pathway. Teenagers with insufficient iodine intake will be short stature and mentally retarded.
Whole wheat food (in most diets) The human body needs carbohydrates to provide energy. The best source of carbohydrates is whole wheat, such as oatmeal, coarse bread and brown rice. They contain bran and germ, as well as energy-rich starch.
It takes longer for the human body to digest whole wheat than direct carbohydrates such as white bread, which will keep blood sugar and insulin at a reasonable level and will soon drop. Controlling blood sugar and insulin levels can reduce human hunger and prevent the occurrence of type II diabetes.
Vegetable oil. Americans get 1/3 calories from fat every day on average, so it makes sense to put them in the lower part of the pyramid.
Note that vegetable oil is specifically mentioned here, not all kinds of fats. Healthy unsaturated fats come from olives, soybeans, corn, sunflowers, peanuts and other vegetable oils, as well as fatty fish such as salmon.
These healthy fats can not only improve human cholesterol levels, but also effectively prevent potential sudden cardiac death and myocardial infarction. Vegetables (in large quantities) and fruits (2-3 times a day).
Eating more vegetables and fruits can effectively prevent heart disease and angina pectoris; Prevent all kinds of cancers; Lowering blood pressure; Relieve intestinal diseases called diverticulitis; Prevention and treatment of cataract and glaucoma, these two eye diseases are the main causes of blindness in the elderly over 65 years old. Fish, poultry and eggs (0 ~ 2 times a day).
This is the main source of protein. A large number of studies show that eating fish can reduce the risk of heart disease.
Muscle and turkey are low in saturated fat, and they are also good sources of protein. Eggs have been demonized for a long time because of its high cholesterol content. In fact, eggs are a good breakfast, much better than doughnuts or flour doughnuts.
Nuts and beans with shells (65438+ 0 to 3 times a day). Nuts and beans with shells are the best sources of plant protein, plant fiber, vitamins and minerals.
Beans with shells include black beans, broad beans, edamame and other dry goods. Many nuts are rich in healthy fat. For example, almonds, walnuts, small walnuts, peanuts, hazelnuts and pine nuts can directly show that food is good for the heart.
Dairy products and calcium replacement (65438+ 0 to 2 times a day). In order to prevent and treat osteoporosis, calcium and vitamin D are needed, and dairy products are the traditional source of calcium for Americans.
Besides foods containing saturated fat, such as milk and cheese, there are other healthy ways to get calcium. For example, three cups of whole milk are equivalent to the saturated fat contained in thirteen cooked bacon.
If you like dairy products, stick to skim or low-fat products. If you don't like dairy products, calcium substitute food is the guarantee to ensure the daily calcium demand of human body.
Red meat and cream (use carefully): These foods are placed at the top of the pyramid of healthy eating because they are rich in saturated fat. If you eat red meat every day, such as beef and mutton, trying fish or chicken several times a week can improve your cholesterol level.
Similarly, you can switch from cream to olive oil. Rice, white bread, potatoes, pasta and desserts (with caution): Why are all these staple foods of Americans placed at the top of the pyramid of healthy eating? Because they can cause blood sugar to rise rapidly, leading to weight gain, diabetes, heart disease and other chronic diseases.
Whole-wheat carbohydrates stabilize human blood sugar, at least increase slowly without exceeding the normal level of human body, so that human body can deal with excess blood sugar. Multivitamins: Daily supplementation of multivitamins and minerals is the nutritional reserve of human body.
The food we eat every day sometimes does not provide all the nutrients the human body needs every day. At this time, multivitamins can fill the nutritional gap, even for the most cautious diners. Please choose genuine multivitamins.
Alcohol (moderate): Drinking a little alcohol every day can reduce the risk of heart disease. Moderate amount is very important. Alcohol is a double-edged sword, which has both disadvantages and advantages.
For men, the balance point is to drink 1 2 cups a day, not draft beer cups. For women, one glass a day is enough.
The pyramid of healthy eating summarizes the best dietary information today. It is not a castle in the air, nor is it static. With the development of the times and the deepening and diversification of research, the pyramid of healthy eating will reflect the latest and most important research results with the times.
7. What foods are helpful for the healthy growth of teenagers?
There is also a scientific basis for growing taller.
■ Ensure a balanced diet
We should pay attention to the nutritional balance of our diet. The general principle of children's diet is to match coarse grains with flour and rice, animal protein with plant protein, and choose different vegetables and fruits according to the season to ensure that children get enough vitamins and minerals every day.
Generally speaking, we should consider adding more meat and eggs with high protein content to children's diet.
■ Develop good eating habits
The biggest bad eating habits of children are picky eaters and partial eclipse. Parents should not force their children to eat rudely, but should patiently guide them step by step. As long as you stick to it, you will gradually get rid of the bad eating habits of picky eaters and partial eclipse. If it is anorexia caused by digestive dysfunction, appropriate drugs should be used to regulate and strengthen the digestion and absorption function to prevent malnutrition and affect the growth and development of children.
■ Develop good work and rest habits
Children's adequate sleep time varies with age. Newborn babies need 18~20 hours, two to three months need 16~ 18 hours and five to nine months need 15~ 16 hours. When the baby reaches 1 year, it takes 14~ 15 hours and 9 ~ 13 years. /kloc-children over 0/3 usually sleep for 8 hours.
A good work and rest system is: eat when it is time to eat, study when it is time to study, try to relax when it is time to rest, and sleep when it is time to sleep. Only by forming a relatively fixed work and rest system can children grow and develop, thus growing into tall people.
■ How to grow taller?
Whether the height is satisfactory depends on several factors. First, genetic factors, accounting for 70%, and other conditions, including sports, nutrition, environment and social factors. In order to make children grow taller, parents should pay attention to the following points:
First, don't miss the rapid growth period.
During the development of children and adolescents, when is the height the fastest? Studies have confirmed that the height of most Han children in China is about 12 years for girls and 14 years for boys. More than 90% of the girls are between 1 1- 13 years old and the boys are between 13- 15 years old. In order to make children grow taller, parents should pay special attention to their nutrition and exercise during the rapid growth period.
Second, we should pay attention to nutritional supplements.
Nutrition is the key to children's physical growth. The energy, protein and amino acids needed for normal growth of the body must be provided by food, mainly meat, eggs, beans and beans. Bone formation also requires sufficient calcium, phosphorus and trace amounts of manganese and iron. Insufficient calcium intake and vitamin D deficiency will lead to insufficient bone mineralization, vitamin A deficiency will make bones shorter and thicker, and vitamin C deficiency will make bone cells brittle and affect bone growth.
At present, the average family should have a comprehensive and adequate nutrition and a balanced diet. Parents should be careful not to let their children develop the habit of partial eclipse, let alone let their children eat too many snacks, which will affect the intake of important nutrients.
Third, don't neglect physical exercise.
Physical exercise can strengthen the metabolic process of human body, accelerate blood circulation, promote the secretion of growth hormone, accelerate the growth of bone tissue, and be beneficial to human body length. The following kinds of exercises have a certain effect on height growth, so try them.

8. What is the common sense of food safety?
(1) Develop good eating habits. Don't wolf down your food; Don't do other things at the same time while eating, not to mention chasing each other; Eat three meals a day regularly and don't overeat.
(2) Develop the habit of washing hands before eating. People's hands do this and that every day, touching all kinds of things. Will be infected with germs, viruses, parasitic eggs. Wash your hands carefully with soap before eating to reduce the possibility of "illness from the mouth".
(3) Wash raw fruits and vegetables. Fruits and vegetables will not only be infected with germs, viruses and parasite eggs, but also remain pesticides and insecticides. If it is not cleaned, it may not only infect diseases, but also lead to pesticide poisoning.
(4) Don't eat wild vegetables and wild fruits casually. There are many kinds of wild vegetables and wild fruits, some of which contain toxins harmful to human body. It is difficult for inexperienced people to distinguish clearly. Only by not eating wild vegetables and fruits casually can we avoid poisoning and ensure safety.
(5) Don't eat rotten food. When food rots and deteriorates, it will have a sour and bitter taste; It gives off a special smell, which is caused by the reproduction of bacteria. Eating these foods will cause food poisoning.
(6) Don't buy or eat the inferior food and drinks of street vendors at will. These inferior foods and drinks are often unqualified, and eating and drinking will be harmful to health.
(7) When buying food and drinks in the store, pay special attention to whether the production date and shelf life are marked, and don't buy expired food and drinks. Don't eat or drink expired food and drinks.
(8) Do not drink raw water. Whether the water is clean or not is difficult for the naked eye to tell. Clear and transparent water may also contain germs and viruses, and drinking boiled water is the safest.
Extended data
Common sense of tourism food hygiene
(1) Pay attention to drinking water hygiene.
Generally speaking, you can't drink raw water. Boiled water and sterilized tap water are the most ideal drinking water for the journey, followed by mountain spring and deep well water. Rivers, ponds and lakes cannot be drunk raw. When there is no qualified water to drink, you can use melons and fruits instead of water.
(2) melons and fruits must be washed or peeled before they can be eaten.
You must peel the fruit when you eat it. Melons and fruits are not only polluted by pesticides, but also by germs or parasites during picking and selling.
(3) Treat every meal with caution and never go hungry.
High-end restaurants can generally eat safely, food stalls can be eaten selectively, and stalls or vendors (carts) should not eat. Although there are a lot of hungry situations during the trip, the food of the street vendors can't be touched. If you are hungry, you are playing with your life.
(4) Learn to identify whether the hygiene of restaurants is qualified.
The general standards of qualification should be: having a hygiene license, clean water source, disinfection equipment, fresh food raw materials, no mosquitoes and flies, dust-proof equipment, clean surrounding environment, no contact between the payee and food, and keeping a considerable distance between money and food.
(5) eating and drinking in vehicles, ships or planes.
When riding, because there is no exercise condition, the digestion process of food is prolonged and the speed is slow. If you don't control your diet, it will inevitably increase the burden on the gastrointestinal tract and cause gastrointestinal discomfort.
