What is the reason why the oven temperature of barbecue at home should not be higher than 200℃?

Many experts point out that one of the nutritional damages caused by cooking methods such as frying and frying is to volatilize iodine in salt, which makes the iodine content in iodized salt different from the iodine content actually ingested by human body. Because the oil temperature required for frying is very high, about 180. Iodine is a lively chemical element, which will volatilize at high temperature. Therefore, after high-temperature frying, the loss rate of iodine in salt can reach 40%-50%. Therefore, if you don't change your cooking habits, even if you vigorously promote iodized salt, people still can't get enough intake. In addition, frying and baking will not only destroy the nutritional components of food, but also produce various harmful substances. The oil temperature of fried and baked foods is high, generally at 180-300.

A series of changes will take place in food at high temperature. Protein foods produce carcinogenic heterocyclic amines, fats produce benzopyrene carcinogens and products of cyclization, polymerization and oxidation of unsaturated fatty acids, and carbohydrate foods produce more acrylamide substances, which are also potential carcinogens. Scientific research has proved that the higher the cooking temperature of food, the more carcinogens it produces, and the more difficult it is for the human body to digest, absorb and metabolize. Low-temperature cooking methods such as steaming, boiling and stewing are most beneficial to human health. Because its processing temperature is around 100, it will not produce harmful substances. Therefore, we should strongly advocate cooking food with steam and avoid using high-temperature cooking methods, which can not only reduce the harm of carcinogens, but also facilitate digestion and absorption. Especially children, the elderly and the infirm, have poor immune function and weak detoxification ability, so special attention should be paid to preventing harmful factors in food.

Many families with ovens can also enjoy barbecues at home. Barbecue is delicious, but it causes cancer. When baked at high temperature, heterocyclic amines and benzopyrene will be produced. When barbecuing at home, the oven temperature should not be lower than 200. Low temperature can greatly reduce the production of carcinogens. Some people are insatiable and live by barbecue. It will cause problems of single nutrition and constipation. When barbecuing, please try baking sweet potatoes, potatoes and lotus roots. There are many carbohydrates, which can be used as both staple food and vegetables. Eating with meat will not only improve the taste, but also improve the nutritional balance, provide a lot of fiber and reduce constipation.
