As the saying goes, "illness enters through the mouth," and the relationship between diet and disease has long been confirmed in medical research. Many of the things we eat every day are precisely overlooked carcinogens. If we are not careful, toxins accumulate over time, and the severe consequences are often unpredictable.
Tea scale. Some people believe that tea scale is formed by the long-term deposition of tea water and is harmless to the body, so they rarely clean it. This is actually wrong. Tea scale contains various harmful metals and some carcinogenic substances, such as cadmium, lead, mercury, arsenic, and nitrites, which can lead to lesions in organs such as the kidneys, liver, and stomach.
The rotten part of fruit. After fruit rots, microorganisms produce various harmful substances during their metabolism, especially with accelerated fungal growth. Some fungi are carcinogenic and can spread from the rotten part to the unrotten part through the fruit juice. Therefore, even if the rotten part is removed, the remaining fruit is still not edible.Moldy rice, peanuts, and corn. The aflatoxin they contain is currently recognized worldwide as a strong carcinogen that can easily cause liver and esophageal cancer. Some people think that washing it several times or high-temperature disinfection can remove the toxic substances. In fact, once aflatoxin contaminates food, it is very difficult to completely remove it.Monosodium glutamate (MSG) in alkaline foods. MSG turns into disodium glutamate when it encounters alkaline foods, losing its umami flavor; when heated to 120°C, it becomes the carcinogen sodium pyroglutamate. Therefore, MSG should not be added to foods containing soda or alkali; when making soups and dishes, MSG should be added before the dish is finished to avoid prolonged cooking.
Burnt fish and meat. When the fat in fish and meat burns incompletely, it produces a large amount of V-methyl derivatives, which is a carcinogen whose strength exceeds that of aflatoxin. Therefore, attention should be paid to the heat when cooking fish and meat. Once burnt, do not eat it.Rotten cabbage. Both rotten and improperly pickled cabbage contain carcinogenic nitrites.Barbecued food. All barbecued foods are prone to a substance with extremely strong carcinogenic ability—benzopyrene, which is the same substance produced by the repeated use of oil in fried foods.Fruits wiped with toilet paper or towels. The disinfection of many types of toilet paper is incomplete, carrying Escherichia coli, pathogenic pyogenic bacteria, fungi, hepatitis B virus, etc. The fillers and powder residues left on tableware and fruits can also affect health.
