Salted fish produces dimethyl nitrite, which can be converted into carcinogen dimethyl ammonium nitrite in the body.
Fish sauce, shrimp paste, salted eggs, pickles, sausages, ham and smoked pork also contain more nitrite carcinogens and should be eaten as little as possible.
2. Moldy food
Rice, wheat, beans, corn, peanuts and other food crops will produce strong carcinogen aflatoxin when they are wet or contaminated by mold.
Therefore, when preserving these foods, we must pay attention to the storage environment, and don't be reluctant to dispose of them because of preservation after discovering that the food is moldy.
3. Sunflower seeds
Sunflower grows fast, easily absorbs heavy metals such as lead, cadmium and nickel in the soil, can effectively reduce heavy metal pollution and purify the environment, and is the best landscape green manure crop.
But for the human body, eating these heavy metals is harmful to the body, and eating sunflower seeds will consume a lot of bile.
It makes the human body's fat metabolism disorder, leading to the accumulation of a large amount of fat in the liver, which will seriously affect the function of liver cells.
4. BBQ food
Barbecue food is cooked at high temperature, and meat processed at high temperature will produce heterocyclic amines and benzopyrene, which are carcinogens.
Therefore, roast beef, roast duck, roast mutton, roast goose, roast suckling pig, kebabs and other barbecue foods should not be eaten more.
5. Fried food
Polycyclic aromatic hydrocarbons will be produced after frying. After coffee beans are burnt, the content of benzopyrene increases by 20 times.
Oil cake, stinky tofu, fried taro horn, fried dough sticks, etc. Most of them use repeated oil, which will produce a carcinogenic decomposition product at high temperature.
6. Expanded food
Popcorn may be the earliest puffed food that people eat, but not many people know that popcorn made by high-temperature sealed lead cans will contain a lot of lead after being taken out of the pot.
Puffed food contains heavy metals. First of all, when processing such foods, additives such as fillers are usually added. Second, food passes through metal pipes during processing.
Metal pipes usually contain lead and tin alloys. At high temperature, these lead are easy to volatilize, and the volatilized lead will pollute the puffed food.
