What is the happiest thing to eat on the road to health?

Healthy Eating "We should eat green food, not junk food ..." This sentence often haunts my ears. Most people know to eat green food, but what is green food? Green food is pollution-free and high-quality food that meets certain standards. Let me give an example! Everyone likes KFC and McDonald's! But do you know how much energy there is in food? Are they green food? In our sight, children aged 6-8 need about 336 kilojoules per kilogram of body weight every day, and children aged 9- 12 need 273 kilojoules. At our age, about 30 kilograms to 40 kilograms need 8 190 to 10920 kilojoules a day. Let me talk about how much energy our favorite food has. A can of 250g coke we drink can generate 460kJ of heat, and a can of 250g soda can generate 502kJ of energy. A 70g serving of ice cream we eat can produce 544 kilojoules, and 10 serving of 70g French fries can produce 377 kilojoules. A 50-gram hamburger can produce 460 kilojoules of energy. Another noodle with a mass of 240 grams can generate energy of 1000 kilojoules, and a packet of fried instant noodles with a mass of 100 grams can generate heat of 1799 kilojoules. If we consume more energy than the standard every day, the excess energy will become fat and be stored in the body, which is easy to make the body obese; If you don't eat enough, you will be malnourished. They are also green food. I go shopping with my mother, who usually chooses some vegetables with intact leaves. I think many people are the same. That's what I thought at first, and it lasted for a year. One day, my mother and I just read in the newspaper that there is no pesticide pollution in buying vegetables with insect eyes. This surprised us. We ate pesticides for a year. Diet is one of the important factors affecting human health. People have to eat a lot of food all their lives, so we must choose healthy food.
