2. Deep-fried food as a traditional Chinese specialty food has been favored by the majority of people, and many of the little fat people in our school are mostly lovers of deep-fried food.
3. Is fried food a healthy food? Why so many little fat on the surface looks very strong, the body is weak to the extreme, a little exercise two laps can not breathe? Analysis of the problem: fried food is a traditional convenience food, the use of fats and oils as a heat exchange medium, so that the fried food in the starch paste, protein denaturation, moisture in the form of steam to escape, so that the food has a crispy special taste.
4. The cooking method of deep-frying can kill bacteria in the food, extend the shelf life of the food, improve the flavor of the food, and enhance the digestibility of the nutrients in the food, so deep-fried food is much loved at home and abroad.
5. However, studies in recent years have shown that the safety of deep-fried foods is a big problem.
6. High-temperature processing of starchy food in the higher content of acrylamide, acrylamide is known to humans may be carcinogenic, its potential harm to human health.
7. Scientific evidence: some products of decomposition and polymerization of oil during high-temperature cooking are toxic to humans.
8. In the process of frying food, when the temperature reaches 250-300 ℃, the same molecule glycerol fatty acids between the fatty acids or different molecules of glycerol ester fatty acid polymerization occurs, so that the viscosity of the oil increase can be generated such as cyclic monomer, dimer, trimer, and multimer and so on.
9. Cyclic monomer can be absorbed by the human body, so the toxicity is strong, the cyclic monomer belonging to the cyclic compounds have been diene cyclic compounds are separated out, according to 20% of the proportion of the mixture of the basic feed fed to the rats, 3 ~ 4d on the death of the proportion of 5% to 10% of the mixture of the measurement of the rats, the emergence of fatty liver and hepatomegaly.
10. Dimer can make animals grow slowly, hepatomegaly, and reproductive dysfunction.
11. Trimer above because the molecule is too large, not easy to be absorbed by the body, so non-toxic.
12. In addition, oil frying marinated fish and meat can form carcinogens nitrosopyrrolidine, long-term consumption will affect human health.
13. Findings: fried food is high in calories, containing high levels of oil and oxidized substances, often eating easy to lead to obesity, is the cause of hyperlipidemia and coronary heart disease risk food, and regardless of the fat in the vitamin A, E and other nutrients in the high temperature is destroyed, greatly reducing the nutritional value of the fat, the single in the deep-fat frying process, which produces a large number of carcinogenic substances.
14. Studies have shown that people who often eat fried food have a much higher incidence of some cancers than those who do not eat or rarely eat fried food.
15. My suggestion: students are growing up, if you want to grow up healthily, I suggest you eat more fresh vegetables, fruits, meat, eggs, and rice and noodles, because these foods contain nutrients necessary for our growth, and they are healthy foods.
