Starting from last year, the city of Guangzhou initiated a pilot project for students from rural schools in the compulsory education stage in Conghua City and Zengcheng City. However, according to the survey, there are two extremes in the current nutritional problems of students, one is malnutrition, and the other is nutritional imbalance. In physical fitness monitoring, students’ continued obesity rate continues to rise. “At present, overweight and obesity rates in Guangzhou students account for about 15% of all students, and the average obesity rate is 6%. Male obesity is more serious.†said Guangzhou Jinzhong Cheng, director of the School of Primary and Secondary Health Care, in 1985. The obesity rate is less than 1%, and the increase in so many “little fat piers†in 30 years should be paid attention to.
Wu Qiang said that the government has begun to pay attention to the nutritional status of students. Guangzhou will prepare student dietary guides, and ask experts to provide nutritious meals for the students' canteens so that the schools can keep students' stomachs. On the other hand, in order to ensure the safety of school canteens, installing cameras for school kitchens will be included in the “Top Ten Livelihoods in 2014â€, and Guangzhou will install cameras for kitchens in nearly 3,000 schools in the city in three years to allow schools to eat and drink. Health and safety are monitored.
