Because lunch serves as a connecting link between the preceding and the following, we should not only supplement the vacancy of less breakfast, large amount of activity and energy consumption in the morning, but also reserve energy for energy consumption in the afternoon. As for dinner, you can’t eat too full. Excess calories will be converted into fat and make people fat. In addition, dinner should not be eaten too late. Six o’clock is the most appropriate!　　So here, I hope students can eat fast food and fried food properly and stay away from junk food on expired stalls and vendors. Wele the new day with healthy body and full spirit!　　This is the end of my speech. Thank you!　　Teachers and students:　　good morning! The topic of today’s speech is “healthy diet, let’s be healthier”.　　Students, the National Student Nutrition Day is ing. Let’s put down our books and take care of our bodies together.　　At about 4 ., with the bell ringing after class, the students walked out of the school gate in groups and rushed to various stalls near the school. The deserted streets became lively. The snack stalls such as fried meat kebabs and omelettes were immediately surrounded by students in school uniforms. Few of the staff of these stalls wear gloves. They are busy collecting money and operating, but the students ignore it. We can see such scenes everywhere.　　As the saying goes, “the body is the capital of revolution”. Yes, good health is very important to everyone, but now there are many kinds of food, all kinds of food factories have sprung up, and all kinds of junk food have followed in the market, including unclean food, expired food, convenience food, fried food, carbonated drinks, and all kinds of sporadic snacks, Even some people spray dichlorvos when curing ham for their own interests, which always endangers our bodies. In addition, with the improvement of living standards, students’ unhealthy eating habits are increasing day by day.　　Finally, we make up a formula to encourage the students:　　Keep your mouth shut and don’t be greedy.　　Drink more boiled water and eat less snacks.　　Exercise regularly and care for your body.　　Pay attention to three meals and a balanced diet.　　That’s the end of my speech.
