In January 2023, at the International Green Week in Berlin, children were listening to the nutritionist's introduction of the nutritional composition of food. Li Qiang, a reporter of our newspaper, is a training and education on diet knowledge and good eating habits, which helps to improve teenagers' diet behavior, nutritional status and health literacy. In the process of promoting food education, many countries have issued some targeted policies and measures and carried out various activities with different characteristics to effectively improve the health awareness, concept and quality of adolescents and children, so as to benefit them for a lifetime. Germany - "What are the characteristics of organic vegetables", a project of "public kitchen" implemented in primary and secondary schools across the country? Please look at this box of carrots. Each one is different in shape and color. It is completely different from the neatly packed carrots in supermarkets. "In front of the BioCompany booth of the" Berlin International Green Week "organic food enterprise held in Germany, a group of primary school students are listening carefully to the staff's explanation. The annual "Berlin International Green Week" is a world-renowned agricultural and food exhibition, attracting 400000 visitors from more than 70 countries and regions around the world every year. In addition to buyers, sellers and professional visitors, the crowds of children at the "Berlin International Green Week" were particularly attractive.

"Just 'change the classroom' and experience hands-on teaching" - exhibitors will provide more than 700 extracurricular activities for local schools in Germany each year, covering topics related to agriculture and food industry, health and gardening. With the support of the German government, each student can enjoy this "extracurricular teaching" only by paying 4 euros.
