1. Chemical methods cause cancer: For example, ferrous sulfate can produce black color, and when combined with other odorous substances, it can become stinky tofu. This is quite dangerous. Too much iron is very harmful to the human liver, and the smelly substance may be caused by the decay of protein, so it is possible that it can cause cancer.
2. Rot causes cancer: The reason why stinky tofu is smelly is that it is undeniable that its smell contains protein putrefaction products - amines, which can react with nitrite to form nitrosamines. I believe everyone knows this. Nitrosamines are strong carcinogens; it is recommended that when eating stinky tofu, it is best to eat more fresh vegetables and fruits, because fresh vegetables and fruits are rich in vitamins, especially vitamin C, which can block the production of nitrosamines .
3. Toadstools damage the nervous system: During the fermentation process of stinky tofu, a large amount of base nitrogen will be volatilized. There is a toxin called "Clostridium botulinum" that often multiplies with the production of stinky tofu. Among them, Clostridium botulinum is a deadly bacteria that secretes toxins during the reproduction process and is one of the most toxic proteins. After people eat and absorb this toxin, the nervous system will be damaged and symptoms such as dizziness, difficulty breathing and muscle weakness will occur. Causes gastrointestinal diseases in humans: The fermentation process of stinky tofu is carried out under natural conditions and is easily contaminated by microorganisms. In addition, stinky tofu uses Mucor species in the early stage of fermentation, and is susceptible to contamination by other bacteria in the later stage of fermentation, including pathogenic bacteria. Therefore, don’t eat too much stinky tofu at one time to avoid gastrointestinal diseases.
4. Unhygienic effects on health: Nowadays, most stinky tofu is made from chemical dyes, sour water, sewage, and even excrement. Unscrupulous operators first cut the tofu into pieces and boil it in water, and add black powder. After a few minutes, the tofu is dyed purple-black. After drying, it is soaked in a bucket full of black and smelly water. The black water is made from snails and rancid water. , rotten meat, and dead flies are used as raw materials, and they are fermented and sealed until maggots grow, producing a pungent odor. If it's not smelly enough, add a little fecal water to increase the smell.
5. Mildew can introduce stomach problems: Stinky tofu itself is moldy food. People with poor gastrointestinal problems should try not to eat it, otherwise it will easily cause stomach pain, bloating, abdominal pain and diarrhea.
6. External processing methods cause cancer: the oil for fried stinky tofu is reused and will not be replaced after frying many times. It contains a large amount of carcinogens, so for the sake of health, It is recommended to eat less.
