How can soy sauce cause liver cancer? Revealing four unfavorable diets that affect liver cancer

Liver cancer is a malignant tumor of the liver. It is a common and frequently occurring disease among surgical diseases. Malignant liver tumors can be divided into two categories: primary and secondary. Primary malignant liver tumors originate from the epithelial or mesenchymal tissue of the liver. The former is called primary liver cancer, which is a highly prevalent and extremely harmful malignant tumor in my country; the latter is called sarcoma, which is relatively rare compared with primary liver cancer.

How could soy sauce cause liver cancer?

Soy sauce is a liquid condiment made from beans, wheat and bran. It is reddish brown in color, has a unique aroma, tastes delicious and helps stimulate appetite. It is a traditional Chinese condiment. It is generally believed that the main raw material of soy sauce is soybeans, and soybeans and their products have anti-cancer effects because they are rich in minerals such as selenium. However, it is worth noting that during the production, storage, transportation and sales of soy sauce, it is often contaminated due to poor sanitary conditions and even carries pathogenic bacteria that cause intestinal infectious diseases. The problem of bulk soy sauce is more obvious.

Experiments have shown that typhoid bacilli can survive in soy sauce for two days, and halophilic bacteria can survive in soy sauce for a long time. In turbid, precipitated, and impure soy sauce, the number of bacteria will be more than 100 times higher than the standard. If such soy sauce is consumed directly without heating and disinfection, it may cause illness.

In addition, researchers have found carcinogens in soy sauce. Epidemiological experts in Taiwan have found that soy sauce consumption is directly related to liver cancer. This is because during the fermentation process of soy sauce, protein decomposes and produces a large amount of amine substances, which will synthesize carcinogenic nitrosamines in the presence of nitrite.

Four unfavorable diets that affect liver cancer

1. Do not eat moldy food

In spring, food is prone to mold. Aflatoxin in moldy food is a liver cancer-causing substance, which takes only 24 weeks to cause cancer. Therefore, food should be properly stored and discarded immediately once it is moldy, especially soybeans, peanuts, sweet potatoes, sugar cane, etc., which should never be eaten. In addition, peanut oil should not be stored for a long time. If it is found to have a rancid smell, it should not be eaten. Otherwise, it will not only taste bad, but more importantly, it will cause cancer.

2. Do not eat or eat less pickled vegetables

Pickled vegetables such as sauerkraut, pickles, and salted fish are refreshing and appetizing. As the weather gets hotter, people lose their appetite and prefer to eat pickled vegetables with rice. However, pickled vegetables contain a large amount of nitrosamines, which have been shown to be related to the occurrence of liver cancer. It is best not to eat them or eat less. And remember, you must pickle them thoroughly before eating.

3. Animal and vegetable oils should not be eaten after they have gone bad

Stale oils all contain the chemical component malondialdehyde, which can generate polymers and react with proteins and DNA in the human body, causing the protein structure to mutate, causing the cells with mutated proteins to lose their normal functions and transform into early cancer cells. In addition, malondialdehyde polymers can hinder the replication of DNA and accelerate the aging process of people. Therefore, animal and vegetable oils should not be stored for too long, and oils that have deteriorated and have a rancid smell should not be eaten. Foods fried with rancid oils not only taste bad, but more importantly, they can cause cancer and shorten people's lifespan.

4. Do not drink or drink less alcohol

Long-term drinking will cause alcohol to digest the gastric mucosa. Once the gastric cells are damaged, the toxic substances in the food will be easily absorbed by the stomach, which can easily cause alcoholic hepatitis, damage the liver's detoxification function, and even cause alcoholic cirrhosis, which is a risk factor for liver cancer. If moldy peanuts are used as a snack, the possibility of inducing liver cancer will be even greater. Dr. Dong recommends that adult men should not drink more than 2 cups of alcohol per day, and women should not drink more than 1 cup.
