Stinky tofu is the most famous snack in Changsha and a must-try for many tourists. Its deliciousness is described as crispy without being burnt, tender without being greasy, with an initial pungent smell that reveals a rich, alluring aroma upon closer inspection. While stinky tofu is delicious, how can you eat it in a healthy and nutritious way?
Every 100 grams of stinky tofu contains about 10 micrograms of Vitamin B12. Vitamin B12 can help slow down the aging process of the brain, thus preventing Alzheimer's disease.
The protein content in stinky tofu is as high as 15%-20%. After fermentation, most of it is converted into amino acids, which are more easily digested and absorbed by the human body, making it a good source of protein for vegetarians.
In addition, eating stinky tofu with chili is beneficial to your health. Studies have shown that after entering the human body, chili can increase gastrointestinal motility, thereby promoting metabolism and ensuring smooth bowel movements, leaving you feeling refreshed.
During the fermentation process, stinky tofu produces a type of "plant-based lactic acid bacteria." Live "plant-based lactic acid bacteria" can regulate intestinal function and has a certain regulatory effect on constipation and diarrhea.
Although stinky tofu is delicious, it should not be eaten in excess. This is because during the fermentation of soy products, substances such as methylamine, putrescine, and tryptamine, as well as hydrogen sulfide, are produced. When these amines are stored for a long time, they can react with nitrites to form nitrosamines, which are carcinogens harmful to health.
Furthermore, the fermentation process of stinky tofu requires very strict control of temperature and humidity. If not controlled properly, it can easily be contaminated by harmful bacteria. In milder cases, this can cause gastrointestinal diseases, while in severe cases, it can lead to the massive growth of Clostridium botulinum, producing a toxic substance—botulinum toxin. Cases of stinky tofu poisoning reported in the past were caused by this toxin.
Finally, it should be reminded that stinky tofu is a fried food, so people with diabetes, high blood lipids, and high blood pressure should consume it with caution and in moderation.
