First, think about the materials used to make food. They are terrible. According to the investigation by the industry and commerce department, the raw materials of those roadside products are simply unqualified. Some people use waste oil to make this material; Some are made of dead pork, and there are even dead flies on them! Do you think people's stomachs are made of iron?
Look again, many "three noes" foods contain "Sudan red", which is a toxic substance that can cause cancer and is strictly forbidden to be used as food. There is usually no manufacturer's address on the packaging of these foods. In order to ensure that the unqualified food they produce will not go bad, a large number of preservatives or artificial colors are added, and even industrial salt is added. After eating, a large number of bacteria enter the human body, causing vomiting and diarrhea. As soon as these things are produced, the monosodium glutamate contained in them seriously exceeds the standard, which is very unfit for eating.
Medical experts say that these junk foods will cause people's memory to decline, which is very unfavorable to the health of teenagers. Long-term consumption will also have a great impact on liver metabolism. Some students have leukemia because of eating roadside products for a long time, and some have acne and spots on their faces. Knowing this, do you dare to eat three foods?
In order not to eat "three-no-food", students should not only have the firm will to resist junk food, but also master some skills to understand "three-no-food": no factory name, no factory address, no production date, generally made of inferior materials, no shelf life and unreliable quality.
Good medicine tastes bitter and is good for illness, but advice when most unpleasant is good for action. Students, for the sake of their own health, I hope everyone will refuse the "three no foods" and mind their own mouths. As long as you can control yourself, you will give your future a blue starry sky!
Thank you!
Healthy eating speech 400 words 2
Teachers and students:
Hello everyone! Today, the topic of our national speech is "Healthy eating starts with me".
The health of every family is closely related to food. With the continuous progress of economy and society, people's diet culture is increasingly diversified, and food hygiene and safety has become a topic of great concern.
Recently, I noticed a situation, that is, every day, we can see shops and vendors near our school selling some three-no food and junk food, while some of our classmates enjoy buying this food with relish. But how many people know that eating them will not only lead to obesity, but also allow a large number of bacteria to invade the human body and cause gastrointestinal inflammation. Therefore, please warn our friends to eat less of this kind of food for their own health.
