. Talk about hygiene and health

1). Talk about hygiene and health

In fact, health is everywhere must pay attention to, in the roadside, on the street, in the alleys, in those stalls vendors stalls, often do some oil cake, stinky tofu and other food, you can never go to buy, who knows what they are made of these things, eat easy to get sick, and even cause diarrhea, dizziness and other symptoms. Wash your hands before and after meals, this is also hygienic behavior.

When it comes to health, some people may say, "Eating more food is also healthy!" In fact, health does not lie in eating more food, you also need to exercise often, drink more water, eat quantitatively every day, sleep on time and so on, so as to be healthy. In the newspaper I saw too much fruit, vegetables, more vitamins, this is very good for the body.

Hygiene and health are closely linked. Lack of hygiene not only makes the body susceptible to disease, sometimes even your precious eyes will be attacked. When you have touched money, moldy books and other things, you can never rub your eyes, otherwise, the bacteria on your hands will run into your eyes, which will make you suffer from trachoma, leading to vision loss.

In order to have a healthy body, we usually have to develop good hygiene habits. Good hygiene habits are not abstract concepts, but rather manifested in a little bit of life. For example, to maintain personal hygiene, clothing should be changed, bathing, nail clipping; wash your hands before and after meals; often clean the environment; and participate in appropriate physical exercise to enhance the body's immunity.

(2) Hot pot should not put too much food, so as not to overcook the food and lose the flavor and nutrition of the dish. (3) food must be cooked and eaten, so as not to be infected with parasitic eggs or bacteria. 9, overeating injures the body in daily life, some people like large pieces of meat, a large glass of wine to enjoy, until the hiccups, drunk, unaware of the hidden disaster has been in which. Overeating, more than the spleen and stomach normal digestion of the amount of food, first of all, is to produce a feeling of fullness, easy to produce indigestion; secondly, a large number of long-term intake of high-protein foods, will make the blood ammonia, and more than the liver, the kidney's ability to deal with ammonia. Produce ammonia poisoning; more serious is a large accumulation of ammonia in the blood will enter the brain tissue with the blood flow, poisoning the central nervous system, light day drowsy and confused, heavy is overeating after sudden death. Scientific diet is a good breakfast food, full of food at noon, dinner food less, avoid overeating. 10, beware of refrigerator storage food poisoning refrigerator as a refrigeration food storage household equipment, bring a lot of daily life, but the refrigerator is not a safe deposit box. Generally speaking, the temperature of the refrigerator freezer is minus 15 ~ 18 ℃, room temperature is only 2 ~ 8 ℃, low temperature on most pathogenic bacteria have an inhibitory effect, but on the cold-loving and cold-resistant bacteria role is not great. Some bacteria can still grow and reproduce below zero. It can be seen that the refrigerator can not inhibit all the bacteria, refrigerator storage food can also be spoiled. 11, raw and cooked food and knife board to separate raw and cooked food separately refers to the production, packaging and storage of raw and cooked food tools. Such as cutting boards, knives and other utensils should be separated and clearly marked, raw and cooked food can not be stored in the same refrigerator or food cabinet.

Or wrongly believe that the frying pan used every day, no need to clean, in fact, this is very harmful to health, especially in the processing of protein- and fat-rich dishes, the formation of carcinogenic substances containing pot scum, often eaten in trace amounts of carcinogens, will be accumulated in the body to leave behind hidden dangers. Therefore, frying should do a good job of a dish on the cleaning of a frying pan, can not be afraid of trouble and buried the root of the trouble. In addition, often used many times cooked oil, high-temperature heating will decompose a large number of heterocyclic amines, polycyclic aromatic hydrocarbons and other intense carcinogens, so after many high-temperature heating of cooking oil should be discarded. 14, why emphasize the need to eat vegetables and fruits every day vegetables and fruits can provide the body with a lot of vitamin C, and vitamin C can not be stored in the body
