In recent years, the incidence of liver cancer is increasing and has become a serious threat to human health. Generally speaking, the occurrence of liver cancer is related to daily diet. Long-term consumption of food that has been preserved for too long or moldy is likely to induce liver cancer, so be sure not to eat food that is moldy! If you smell moldy rice, or find that milk has become sour, or think that cooking oil is contaminated with mold, throw them away! Because after the moldy food, microbial metabolism will produce a very toxic strong carcinogenic substances – aflatoxin, it is a very toxic substances, into the human body after the main damage to the human liver tissue. As the detoxification organ of the human body, the liver is responsible for the decomposition and transformation of toxic substances in the human body, and when there are too many toxins for the liver to decompose, they will remain in the liver. Too many toxic substances accumulate in the liver will inevitably harm liver cells, and over time, liver cells will die. Many people think that only the rotten part of a moldy apple is infected by mold, so as long as this part is cut off, the remaining part is still good and can continue to eat. This is actually not true. Once the food begins to mold, the part that has not completely deteriorated has also entered the process of microbial metabolism, has produced a large number of bacteria and toxins invisible to the naked eye. If we eat it, there is a high probability of acute poisoning. Fever, abdominal pain, vomiting, anorexia and other physical discomfort will have to torment us for at least three to five days, and in serious cases, even toxic liver disease manifestations will occur in a few months, jaundice, liver enlargement, pain in the liver area, splenomegaly, ascites, swelling of the lower limbs and abnormal liver function, and may also appear heart enlargement, pulmonary edema, and even cramps and coma. Therefore, in life we must pay attention to the preservation of food, do not eat food that has been preserved for too long or spoiled, although “thrifty” is a virtue, but it brings our body is a fatal injury! For food that has been moldy, we should also treat it differently. Do not eat food that is obviously moldy, especially peanuts, corn, melon seeds, walnuts and so on. Even if you occasionally eat a nut with moldy taste, you should immediately spit it out and rinse your mouth carefully, because aflatoxin can accumulate in the human body, do not mind the trouble to swallow it! When buying nuts, peanuts, grains, etc., try to choose the small package, unless there are many people in the family. Try not to leave it too long, smell it first when you eat it, and throw it away as soon as you find that it doesn’t taste right. For mildly moldy food, you can take some measures to remove the poison. Vegetable oil that has been left for a long time may produce a small amount of aflatoxin, so do not look at supermarket specials and buy a bucket of three or five to stock up. Do not eat the oil raw, you can wait for the oil to heat up and add some salt, because the iodide in the salt can remove some of the toxicity of aflatoxin. When storing oil and other foods, keep them cold, ventilated, dry and out of direct sunlight, and do not use plastic bags for food. If the rice at home is found to have a slight moldy smell, then it must be fully rubbed and rinsed before steaming, because aflatoxin is mostly present on the surface of the seeds, and scrubbing can remove a large amount of toxins from the surface of the grain. Cooking rice in a pressure cooker is also better for removing toxins from rice. A recent research results show that substances such as chlorophyll in green vegetables can effectively reduce the toxicity of carcinogenic aflatoxin and reduce the absorption of aflatoxin by the body. Researchers point out that spinach, broccoli, cabbage and other greens are rich in chlorophyll and chlorophyllic acid. We must pay more attention in life, not to eat long-standing moldy food, so as to avoid the harm of aflatoxin to the human body and reduce the risk of liver cancer!
