origin:
The Chinese Student Nutrition Promotion Association established in 1989 under the auspices of nutritionist Yu Ruomu, combined with WHO's strategic goal of health care for all in 2000, formulated a nutrition work plan for students from 1991 to 2000. The plan was named "Guarding the Seedling System Project," which determined that May 20th each year is China's student nutrition day. Its purpose is to extensively and in depth publicize the importance of nutrition during the student's time, and vigorously popularize nutrition knowledge.
On May 20, 1989, the Ministry of Health and the Ministry of Education jointly launched the "Chinese Students' Nutrition Day". It has been more than a dozen years ago.
Since 1990, the Chinese Student Nutrition Promotion Association has organized student nutrition promotion activities on May 20 each year. Over the past few years, this publicity campaign has been welcomed by teachers and students, parents, and the active participation and support of many nutrition experts. In some places, a regular “Student Nutrition Day†has been formed. In order to make the student's nutrition publicity work more extensive, deeper, and long-lasting, and to promote the institutionalization of student nutrition advocacy work, in May 2001, the Ministry of Education and the Ministry of Health jointly promulgated the document (Wei Wei Controlled Hair [2001] No. 120). The document stipulated "Chinese student nutrition day".
Current student nutrition status survey:
At present, the nutritional status of Chinese students is not optimistic. Although dietary calorie supply basically meets standards, the supply of protein is low, the proportion of high quality protein is small, and nutrients such as calcium, zinc, iron, and vitamin A are obviously insufficient. Due to the low utilization rate of iron in the diet, the prevalence of iron-deficiency anemia in people under 20 years of age in China is 6-29%. The three meals a day for elementary and middle school students in the city are generally sloppy for breakfast, lunch for Chinese food, and rich dinners. In fact, breakfast should be rich. The proportion of plant-derived iron in the diet of students is too high, and the quality of iron is poor and absorption is low. The intake of calcium by students is only 40.6% of the relevant standards, which is related to the low consumption of dairy products and beans in the diet of students. It is worth mentioning that at present, secondary school students have a heavy academic burden and do not pay attention to their diets, resulting in poorer nutritional status than primary school students. Urban students have a high level of living and students have a partial eclipse. They eat high-calorie chocolates and biscuits, and lack physical exercise and physical activity. However, children in rural areas do not have a partial eclipse and the amount of activities is relatively large. Therefore, the general nutritional status of urban children is inferior to that of rural children.
Due to poor eating habits, students in primary and secondary schools are increasingly picky eaters, anorexia, and partial eclipses. Many students develop habits of eating snacks and not eating staple foods, leading to an increase in malnutrition among students. Coupled with the great pressure of study and spirit, it is easy to suffer from diseases such as anemia.
In addition, because many students and parents lack proper nutrition knowledge and students take one-sided intake of high-fat and high-protein foods, and the lack of exercise, the incidence of obesity in adolescents in China is increasing year by year, and in some places as high as 15,3%. The bad eating habits and lifestyles of teenagers have laid a “time bomb†for chronic diseases such as cardiovascular and cerebrovascular diseases, hypertension, diabetes, and hepatobiliary diseases.
The need for healthy nutrition:
The pros and cons of nutritional status and nutritional components are important factors affecting the quality of a nation’s population. It is directly related to the physical and intellectual development of adolescents. Jiang Jianping, director of the National Student Drinking Milk Program Expert Committee, believes that due to malnutrition caused by the lack of certain nutrients, it has not disappeared naturally following economic development. According to him, there are statistics showing that, regardless of the urban and rural areas, the average daily intake of calcium in primary and secondary school students is obviously insufficient, only reaching 40% to 50% of the supply standard.
In particular, the nutritional status of rural children is even more worrying. The rates of low body weight and growth retardation of rural children under 5 years of age are 23.9% and 29.5%, respectively, directly affecting the healthy growth of children and adolescents. At the same time, the prevalence of obesity among urban primary school students has risen rapidly. For example, in 2001, Beijing was as high as 15% to 17%, which was 10% higher than the national average. Obesity has become a prominent issue. Due to the insufficient amount of physical exercise among primary and secondary school students, the index of physical fitness of students in 2000 decreased compared with that in 1995.
Guo Wei, deputy director of the Chinese Society of Nutrition and Health Promotion, said that the average height of 11- to 14-year-olds in China is 2-3 cm shorter than that of their peers in Japan. The body lacks vitamins and trace elements such as calcium, iron, zinc and malnutrition. According to statistics, the malnutrition of children in the western region is more serious than that of the eastern part. The proportion of children whose body height and weight are not up to standard is 20%, and the proportion of growth retardation is as high as 30%. Experts believe that vigorously promoting popularization of nutrition science and food hygiene knowledge and eliminating "nutrient blindness" has become a top priority in China's urban and rural areas.
Hand Protection mainly is many kind of work glove.
From the point of safety production, the hand is the area where the human body is injured. So it is particularly important to choose and use safe working gloves to prevent hand injuries.
Many of the chemical adversaries are deadly. Therefore, the permeability, penetration and degradation of the protective gloves determine their protective properties.
