The causes of malignant tumor development are the result of the long-term combined effect of many factors, including the factors of living environment, human body’s own immunity, metabolic function and genetic factors, etc. Diet is also one of the factors triggering cancer. But no matter how to say, scientific and balanced diet and healthy lifestyle are necessary to maintain a healthy body. Three types of food are on the cancer “blacklist” 1. Barbecue food: barbecue grease contains many carcinogens When barbecue is held over open fire, the grease from barbecue meat dripping on red charcoal will produce carcinogenic substances – polycyclic aromatic hydrocarbons (PAHs), including benzo(a)pyrene, tetramethylen and more than 400 carcinogenic compounds. These compounds are carcinogenic. Some of these carcinogenic compounds enter the human digestive tract through barbecue, and some enter the human respiratory tract through barbecue fumes, and the accumulation of these carcinogens in the body can induce stomach cancer, intestinal cancer, breast cancer, colon cancer and so on. Barbecue to eat healthy, one is to choose the right way to grill, should choose the oven grill, electric grill. Second, less fatty meat, the production can be baked with meat skin, but should be removed when eating meat skin, burnt must not eat, because the burnt part of the carcinogenic content of the most. 2, puffed food: eat more prone to heavy metal overload Popcorn may be the earliest people eat puffed food, but not many people know that the high-temperature closed cans of lead made of popcorn, out of the pot will contain a lot of lead. Often eat puffed food is very harmful to children, lead will slowly accumulate in the blood and bones, it is difficult to be metabolized naturally out. When the accumulation of harmful heavy metals to a certain amount, it will cause significant damage to the body’s nervous, digestive, hematopoietic and other systems, especially leading to cognitive impairment or reduced thinking ability. 3, fried food: make people sick mind not light for frying food oil used more times, will become what we call “thousand rolled oil”. Thousands of rolled oil contains a large number of trans fatty acids, which can cause great harm to the human body. Such as fatty liver, high blood pressure, cholecystitis, gastric disease, diabetes, obesity, and may even increase the risk of cardiovascular disease and a variety of cancer. Doughnuts are a favorite breakfast for many people, but in order to pursue the taste, some unscrupulous operators will add puffing agents in the doughnuts. If you eat too much food containing this puffing agent, the first and most likely to damage brain tissue, may lead to the development of Alzheimer’s disease. Therefore, these three types of food as little as possible to eat or do not eat.
