1. Repeated boiling of water and overnight vegetables

Repeated boiling of water will produce nitrite, and overnight vegetables and sauerkraut will also produce nitrite. When eaten, it is converted into carcinogenic nitrite amines in the body.

2. Pickled processed foods

Pickled foods, such as salted fish, pickled vegetables, bacon and ham, may also be produced during the pickling process. Dimethylnitrite will be converted into carcinogenic dimethylnitrite amine in the body after consumption. Long-term consumption of this type of food will increase the risk of gastric cancer, intestinal cancer, and pancreatic cancer.

3. Moldy and spoiled food

Moist and moldy food, such as rice, grains, beans, corn and peanuts, etc., if contaminated by mold, will produce the carcinogen Aspergillus aflatoxin. Aspergillus flavus is the most carcinogenic chemical currently known and is more than 60 times more toxic than arsenic. Aspergillus flavus can easily grow on rice, peanuts, corn and nuts, is difficult to dissolve in water, and is also very heat-resistant. , it is difficult to remove by washing and conditioning.

4. Barbecue and smoked food

Excessive nitrite is produced during the pickling process of barbecue food. Burnt food also contains the strong carcinogen phenylpropylpyrene. This harmful substance is closely related to If the gastric mucosa is in contact, the rate of gastric cancer will be more than 20 times higher than that of those who do not eat barbecue. Smoked food is also pickled, and incomplete combustion during the smoking process produces a large amount of polycyclic aromatic hydrocarbons, which will contaminate the food. Eating barbecue smoked food for a long time is prone to esophageal cancer and gastric cancer.

5. Fried foods

For fried foods such as pancakes, fried dough sticks, stinky tofu, etc., most businesses use oil that is repeated many times, which will produce carcinogens at high temperatures. When fried food is charred, it will produce carcinogens polycyclic aromatic hydrocarbons and benzopyrene. For people who often eat fried food, their internal organs will be damaged, and long-term consumption may cause cancer.
