"We should eat green food instead of 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.

Part II: Health and Diet

We live in an era of advanced technology and abundant food. Supermarkets are full of dazzling snacks, and shops are also full of beautifully packaged food. Red, orange, yellow, green, blue and purple, everything is complete. However, viruses and bacteria followed.

Especially at the school gate, there are stalls everywhere along the road. The contents are disgusting. What veyron, spicy strips, in my opinion, are extremely toxic poisons! Because these are "three noes" products. However, some students like eating very much. No wonder today's children are so weak, so sick and not as strong as before.

I remember it was mentioned in the newspaper before that a child ate junk food sold at the school gate every day. One day at noon, he suddenly felt a stomachache. So, I went to the hospital for examination and actually got acute gastroenteritis.

Also, the breakfast at the school gate is very unsanitary. An hour in the morning is worth two in the evening. Breakfast is very important. But some children like to be perfunctory, just buy something and go to school after eating it. But I'm not one of them. So I will obediently finish all kinds of nutritious breakfast cooked by my mother.

I appeal: friends, eat less snacks and eat more fruits and vegetables. Be responsible for our health!

Part III: Diet and Health

As the saying goes, "Food is the most important thing for the people." In today's society, many restaurants have mushroomed, and various cuisines have flocked, including Fujian cuisine, Sichuan cuisine, Guangdong cuisine, Shandong cuisine, Italian cuisine, French cuisine, Japanese cuisine, Korean cuisine and so on. As we all know, health is the capital of doing anything, and health is closely related to food. Today, let's look at the food on the table.

There are many kinds of food, such as fruits and vegetables, beans, meat, cereals, dairy products, fat and so on. These categories combine to form a food pyramid that affects our health. Therefore, when eating, it is necessary to mix reasonably, with more vegetables and fruits and less meat fat. Cereal is the staple food, beans and dairy products can be appropriately increased, and it should be remembered that eating only eight points full, not picky eaters and anorexia, and not overeating, eating clean food is the most important.

In food, one element plays an important role in people's health-vitamins. Vitamins are divided into A, B, C and D, and different vitamins have different functions. Vitamin A is usually found in red and black foods, such as carrots and black beans. Its main function is to protect eyes, which can be used to protect eyesight and treat night blindness. Vitamin C is usually found in vegetables and fruits, which is beneficial to the treatment of scurvy and skin diseases. There is another story about its discovery: a ship drifted at sea for a few days, and many sailors got scurvy. One of them was seriously ill and abandoned on a desert island. After that, the sailors ate a lot of lemons, but the scurvy disappeared. The news spread from mouth to mouth and from mouth to mouth. Later, scientists found a lot of vitamin C in lemons to treat scurvy. Vitamins B and D also have many functions, so I won't say much here. Of course, we should also pay attention to: some foods should not be mixed together to avoid danger. If shrimp can't be eaten with vitamin C, crabs can't be eaten with persimmons. ...

Now people want to be healthy and eat many supplements, such as velvet antler, ginseng and ganoderma lucidum. I recommend Antarctic krill to you here. It is not shrimp, but it is more nutritious than shrimp. Protein is 2-3 times as large as other animals. It doesn't matter if you catch 30 million tons every year, so it is called "cold lulu".

There are many places in the diet related to health. I hope everyone will pay more attention to it in their daily life. Only by eating a reasonable diet can they have a healthy body.

Chapter 4: Eat healthily with me.

Throughout the ages, whether rich or poor, are inseparable from eating. But how can we eat healthily?

Today, my parents and I went to the supermarket, and we came to the food section. The variety of food here is dazzling, which dazzles me. Nowadays, businesses are making a big fuss about food and launching many novel foods to attract customers' attention. Look, fish and beef join hands to create "farmers and the sea"; The fruits had a party and turned into a "farmer's orchard" ...

Recently, there are great security risks in food: the "poisoned rice" incident in Japan; "Sudan Red" of "KFC"; Melamine in milk powder &; No; ..... So now, we are not at ease with the ordinary food we used to eat every day: drinking milk is afraid of melamine; Eating rice is afraid of poison; Eating vegetables is afraid of pesticides; Eating fruits and drinking drinks are afraid of pigments. ...

The Spring Festival of 20XX is coming, and every household will inevitably visit relatives and friends and have a big meal. If you eat without restraint, then this year will be very hard! Therefore, we should eat more fruits and vegetables and have a safe Spring Festival.

I sat by the window, worried about the night sky, and gently called to the food merchants: "Please produce healthy food and let us eat healthy food!" " "

Oh, when will our diet be safe and healthy?
