Problems with nutrition among today s middle school students

Advocate fat-free milk bottled water, and the United States prescribes a healthy food list for teenagers.

China **** News: The Center for Public Interest Science in the United States issued a list of healthy foods for adolescents on the 16th, so that vending machines in schools across the United States will no longer have harmful drinks and foods such as soda, sugar cubes, sweetened fruit juices and granola snacks, so as to protect the health of teenagers.

According to the United States**, the "least healthy foods" listed by the Center for Public Interest Science on the healthy food list are: Coca-Cola, Pepsi, Kit Kat candy bars, Oreo cookies, in addition to some chocolate and whole dairy products.

At the same time, the Science Center recommended the following "healthy foods" to teenagers: unsweetened applesauce, Nestlé fat-free milk, other brands of low-fat and fat-free milk, bottled water, 100 orange juice and raisins.

Surveys show that 15 percent of adolescents between the ages of 6 and 19 in the United States are obese. Therefore, the center believes that adolescents should eat less foods that are high in sugar and fat.

However, there are also some contradictions on the healthy food table of the Center for Science in the Public Interest. For example, they suggested that teenagers replace Coke with 100 orange juice, but when compared, the same serving of 100 orange juice contained 25 more calories than Coke, and the same serving of low-fat milk also had 5 more calories than Coke. It seems that how to protect the health of teenagers is really not an easy task.

There are also some psychological problems.

In a nutshell, there are a few points:

Interpersonal relationships – the pressure of communication with classmates and teachers;

Personal image - the child in adolescence always has an unsatisfactory feeling about his appearance and body shape;

Family relationships – there is a generation gap with parents and the elderly;

Social Relations - The influence of pornography, gambling, drugs, superstition, and Western decadent culture on children;

Online games – young people are exposed to online games before they know the real and the virtual, which will seriously affect their correct understanding of life and society, leading to many tragedies;

Academic performance - in the era of "points are the root of life", the pressure can be imagined;

There are also some more common ones, such as youth beans.

Overnutrition is widespread.

Many students are overweight.

With the rapid development of society, people's living standards have also been greatly improved, and there have been obvious improvements in all aspects of clothing, food, housing and transportation, the most significant of which is the aspect of diet, the most common on the street, the most is restaurants, restaurants, etc., all kinds of food are dazzling. Generally speaking, the probability of malnutrition in recent years will be greatly reduced, but this is not the case, a large number of primary and secondary school students will be malnourished every year, so what is the cause of this? In my opinion, the main causes of malnutrition among primary and secondary school students are as follows.

1. Malnutrition is also caused by long-term insufficient nutritional intake, slight malnutrition will lead to a decrease in the body's immunity, often cold, fever, etc., weakness, yellow muscles and thin muscles. More severe malnutrition will affect the normal development of children, intelligence, height will decline, and even cause rickets. Therefore, malnutrition is very serious for adolescents who are in the period of growth and development, and we should pay great attention to this disease, and timely supplement nutrition to promote the normal development of the body.

2. The main causes of malnutrition among primary and secondary school students are as follows. First, the eating habits are irregular, many primary and secondary school students often think that the morning time is too tight, and they choose not to eat or eat snacks casually in order to sleep a little longer. Most of the students eat at school at noon, and due to various reasons, the school meals are not nutritious enough, and some students will skip lunch for snacks.

When it comes to dinner, it is often too hearty, which will directly induce obesity. Eating an irregular diet for a long time can lead to inadequate nutrient intake. Second, with the improvement of living standards, many primary and secondary school students do not eat on time, but choose to eat instant noodles, takeaway and other high-fat fried food, although this food tastes better, but basically has no nutrition, and is not clean, long-term eating will not only cause malnutrition, but also reduce the body's immunity, cause various diseases.

In short, irregular life and eating habits are the main cause of malnutrition among primary and secondary school students, therefore, parents should urge their children to develop healthy living habits, insist on exercise, strive not to be picky eaters, eat more vegetables and fruits and other foods rich in vitamins and proteins, to prevent malnutrition.

It should be that the food is not of high nutritional value. Primary and secondary school students should try to eat less junk food, eat more green food, eat less takeout, and try to cook at home to eat if possible.

Middle school students are under a lot of pressure to study and stay up late for a long time, so they are malnourished and put their bodies in a sub-healthy state.

It may be because elementary and middle school students do not exercise regularly, or it may be due to poor eating habits of elementary and middle school students.

Lack of weight gain or loss is the first symptom of malnutrition, and in people who have been sick for a long time, the length is lower than normal, and the subcutaneous fat layer gradually decreases or disappears. Significant emaciation is a characteristic of the disease. The order of subcutaneous fat loss is the abdomen first, followed by the chest and back, waist, upper and lower limbs, buttocks, and finally the forehead, neck and cheeks.

Division. It also manifests as dryness, pallor, slack and loss of elasticity. The muscles of the child are often underdeveloped and the muscle tone is low, and sometimes it is strengthened.

Motivation can be stunted. Severely malnourished people have low body temperature, sluggish mental development, and often cry and irritability at first, and then become dull and unable to sleep.

Better, less responsive to the surrounding environment. It is often accompanied by diarrhoea and vomiting. Severe malnutrition is due to a lack of protein in the body, and the serum protein is significantly reduced, resulting in a decrease in serum colloidal osmotic pressure and edema. Malnutrition can also be accompanied by the following manifestations:1Nutritional anemia is caused by a lack of protein and hematopoiesis.

It is mostly caused by nutritional anemia. 2.Multivitamin deficiency. Vitamin A deficiency is common, with B, C, or D deficiency.

Malnutrition may be caused by certain diseases, resulting in long-term insufficient food intake or inadequate food intake, absorption, utilization, and metabolic consumption.

more, all of which can lead to the occurrence of malnutrition. It is more common in digestive system diseases, diarrhea, digestive tract malformations and other diseases, acute and chronic infectious diseases, measles, hepatitis.

Tuberculosis, or parasitic diseases, such as congenital deficiencies and low physiological function, such as multiple births, multiple births, twins, premature births, etc., are more likely to cause malnutrition.

If you are very emaciated and have a very poor physique, it is best to go to the hospital for a diagnosis, find the root cause of malnutrition, and then carry out targeted **.

In terms of daily life, you can enhance nutrition and eat more carbohydrates, vitamins and protein-rich foods.

If you don't have energy when you study, you will be very tired, especially for candidates in the third year of junior high school and senior high school, if you don't have nutrition and health, it will be harmful to your studies.
