Talking about health 1). Talking about hygiene and health In fact, hygiene must be paid attention to everywhere. On the roadside, in the street, in the alley, in the stalls of those vendors, you must never buy some food such as oil cakes and stinky tofu. Who knows what they are made of? They are easy to get sick and even cause diarrhea, dizziness and other symptoms. Washing hands before and after meals is also a hygienic behavior.
Speaking of health, some people may say, "If you eat too much, you will be healthy!" In fact, health does not lie in eating more. You should exercise regularly, drink plenty of water, eat on time every day, go to bed on time and so on, so as to be healthy. I read in the newspaper that eating too many fruits and vegetables and eating more vitamins is good for your health.
Hygiene and health are closely related. Bad hygiene habits not only make your body easy to get sick, but sometimes even your precious eyes will be attacked.
When you come into contact with money, expired books and other items, never rub your eyes, otherwise the bacteria on your hands will enter your eyes, causing trachoma and reducing your vision. In order to have a healthy body, we should develop good hygiene habits in peacetime.
Good hygiene habits are not abstract concepts, but are manifested as small things in life. For example, keep yourself clean and tidy, change clothes frequently, take a bath frequently, and cut your nails frequently; Wash your hands before and after meals; Clean the environment frequently; Take part in physical exercise properly to enhance immunity.
(2) Eat healthy food and pay attention to eating hot pot. In cold weather, people like to eat hot pot, but we should pay attention to the following hygiene habits: (1) Food should not be overheated, and overheated food can easily burn oral mucosa, esophagus and gastric mucosa, and induce diseases of esophagus or stomach. (2) Don't leave too much food in the hot pot, so as not to cook the food for too long and lose the flavor and nutrition of the dishes.
(3) Food must be cooked before eating, so as to avoid infection with parasite eggs or bacteria. 9, overeating hurts the body In daily life, some people like to enjoy large pieces of meat and large glasses of wine until they are full of food and drink, but they don't know that hidden dangers are already in it.
Overeating exceeds the normal digestion of the spleen and stomach. First of all, it produces a feeling of fullness and is easy to indigestion; Secondly, when a large number of high-protein foods are ingested for a long time, blood ammonia will increase greatly, exceeding the ability of liver and kidney to process ammonia. Produce ammonia poisoning; More seriously, a large amount of ammonia accumulated in the blood will enter the brain tissue with the blood flow, poisoning the central nervous system, ranging from being groggy and unconscious all day, to sudden death after overeating.
A scientific diet is to eat well at breakfast, eat well at noon and eat less at dinner to avoid overeating. 10, beware of food poisoning in the refrigerator. As a household equipment for refrigerating food, refrigerator brings a lot of convenience to people's daily life, but refrigerator is not a safe.
Generally speaking, the temperature of the freezer is-15~ 18℃, while the normal greenhouse is only 2~8℃. Low temperature can inhibit most pathogenic bacteria, but it has little effect on psychrophilic bacteria and psychrophilic bacteria. Some bacteria can grow and reproduce below zero.
So the refrigerator can't inhibit all bacteria, and the food stored in the refrigerator will go bad. 1 1. Raw and cooked food and knives should be separated. Raw and cooked food refers to the tools for making, holding and storing raw and cooked food.
Such as chopping boards, knives and other appliances should be placed separately and marked clearly. Raw and cooked food should not be stored in the same refrigerator or cupboard. Cooked food is easy to be polluted, causing intestinal diseases and parasitic diseases, which is harmful to the body.
12. What does a balanced diet mean? Food should be varied and light, with coarse grain flour and rice. Eat less fat and sweets and more vegetables and fruits. 13. Clean the wok in time to keep healthy. Some people don't clean the wok in time after cooking to save trouble, and then fry the next dish, or mistakenly think that the wok is used every day without cleaning. In fact, it is very harmful to health, especially when processing protein and fatty dishes, it will form a pot scale containing carcinogens, and eating a small amount of carcinogens often will leave hidden dangers in the body.
