2. From the nutritional point of view, food cooked at high temperature will lose more nutrition, protein and vitamins in ingredients will be destroyed, and the nutritional value will be reduced. In addition, barbecue is mainly meat, and a lot of heavy spices are often brushed. Beer or drinks will be served with meals. Salt, sugar and calories are easy to exceed the standard after meals.
3. From the perspective of food safety, high-temperature baked food will produce "advanced glycation end products", which will reduce cell elasticity and increase the risk of heart disease.
In meat food, fat will produce polycyclic aromatic hydrocarbons such as benzopyrene at 300℃, which is a strong carcinogen and may cause liver cancer, lung cancer, stomach cancer, bladder cancer and skin cancer. Protein will produce heterocyclic amines at 200℃, which are carcinogenic and mutagenic, and are related to intestinal cancer, breast cancer and prostate cancer. Starch food will produce acrylamide above 120℃, and the more brittle it is, the more it will be.

Matters needing attention in eating barbecue
1, remove oil and coke.
When barbecuing, the fatter the meat, the more carcinogens are produced. Eat less fat, choose more chicken, fish, shrimp and lean meat, and wipe off the grease on the food surface with oil-absorbing paper or kitchen paper before eating. In addition, there are often many carcinogens on burnt parts and smoked bamboo sticks, which should be wiped clean with paper towels before eating.
2, the nutritional mix should be rich
One of the most important fruits and vegetables can't be less. Eat with raw green leafy vegetables wrapped in barbecue, or mix a cold dish with purple cabbage, broccoli and cauliflower. Then eat some fruits properly after meals and take in antioxidant and anticancer components such as vitamin C as much as possible.
In addition, eat some garlic, in which allicin has different degrees of inhibition or killing effect on a variety of pathogenic microorganisms and tumors; Eating coarse grains containing dietary fiber can promote the discharge of carcinogens; Drink some green tea. The anticancer effect of tea polyphenols can also reduce the harm of barbecue.
Step 3 sit against the wind
Open fire barbecue is more likely to produce carcinogens, which can be baked by electricity or natural gas stove. Try to stay away from the barbecue. If you can't avoid it, you'd better sit in the upwind direction, which can reduce the chance of contact with lampblack. Take a bath and wash clothes as soon as possible after eating barbecue to reduce the harm of "second-hand" oil smoke.
