Objective:
To explore the effectiveness of healthy school canteen intervention on nutritional literacy, food consumption, as well as attitude towards school canteen.
Methods:
A primary school in Taizhou City was selected as the intervention school, and another comparable primary school was selected as the control one. A total of 320 students (163 in the intervention group and 157 in the control group) received a comprehensive intervention based on the construction of a healthy school canteen in the school,incluling healthy dining environment,food impravement,chef training,nutrition and health education, while the control group did not receive any intervention. Questionnaires survey was administered to both groups before and after the intervention.
Results:
Before the intervention, no significant differences were found in the total scores of skills and nutrition literacy, frequency of food intake, behaviors and attitudes related to canteen construction between the two groups( P >0.05). Daily intake of vegetables, dairy products, fish/poultry/eggs/lean meat increased by 19.63, 15.95 and 19.63 percentage point respectively ( χ 2=15.25,9.14,13.93, P <0.01). The proportion of students reporting have read related intervention materials in the intervention group(95.71%) was higher than the control group(84.71%) ( χ 2= 11.04, P < 0.01 ). The students in favor of low salt, low oil and low sugar dishes in the intervention group (74.85%) was higher than in the control group(48.41%) ( χ 2=23.73, P <0.01).
Conclusion
Based on the comprehensive intervention of nutrition and health canteens can improve students nutrition literacy and dietary structure. It is recommended to adopt the form of "home school linkage" to carry out the construction of large sample, multi regional and long term nutrition and health canteens.

The global production and consumption of sugar-sweetened beverages (SSBs) has been on the rise in recent decades. The intake of SSBs has been increasing in China, and it is more prevalent among children and adolescents. As research continues to intensify, more and more studies have shown that, in addition to the increased risks of dental caries and obesity reported by the World Health Organization (WHO), SSBs intake can also increase risks of chronic diseases such as diabetes, cardiovascular disease, gout, and cancer, and early death, adding to the burden of disease. Due to the health risks associated with the overconsumption of SSBs, many countries around the world have taken measures to control the intake. The main measures currently in place are taxation of SSBs, restrictions on marketing and sales of SSBs, front-of-package labeling and reducing availability of SSBs in schools. In China, the main measures currently in place are to control the sales of beverages in schools, with Shenzhen taking the lead in implementing health warning labeling to alcoholic beverages and carbonated beverages, extending the measures to reduce SSBs intake beyond school grounds.

Background Excessive intake of sugar-sweetened beverages (SSBs) is harmful to health. In recent decades, the consumption of SSBs by Chinese residents has increased rapidly, increasing the risk of death and burden of disease. Objective To analyze the knowledge level and influencing factors of SSBs for Chinese residents aged 18-64 years in 2021. Methods A multi-stage cluster random sampling approach was used to conduct a questionnaire survey among residents aged 18-64 years in 302 survey sites across the country in 2021, and
