Visiting the night market occasionally smells stinky tofu. Looking up, the store posted a message: "Stinky tofu contains vitamin B 12, which can prevent you from being delirious ..." Is it really so magical to eat stinky tofu for health preservation? What are the benefits of vitamin B 12 to human body? Listen to the pharmacist Zhao Shunrong.

Dementia is a progressive degenerative disease of the brain, so that the degeneration of brain cells leads to the decline of other nerve functions, which leads to the decline of memory and the influence of intellectual ability? Symptoms of cognitive dysfunction such as language, calculation ability, judgment and life ability and mental symptoms such as interference behavior, personality change, delusion or hallucination may occur at the same time. The severity of these symptoms will affect a person's ability of daily living.

Malnutrition is related to dementia.

Zhao Shunrong, pharmacist, chairman of the Taiwan Province Provincial Association for Preventive Health Care, said that many recent studies have found that diet is closely related to dementia, including malnutrition, abnormal metabolism, central nervous system diseases, drugs and alcoholism. In the malnourished part, for example, lack of nutrients such as vitamin B 12 and folic acid may also cause dementia. However, the scientific evidence of preventing and improving dementia still deserves further clinical confirmation and expectation.

Stinky tofu contains vitamin B 12 after fermentation.

Vitamin B 12 is water-soluble and the only vitamin containing major minerals. B 12 can only be synthesized by microorganisms. Intestinal microorganisms in human body may provide some vitamin B 12, but killing intestinal bacteria when using antibiotics may reduce the source. Pharmacist Zhao Shunrong reminded that plant foods do not contain vitamin B 12, so long-term vegetarians are in danger of vitamin B 12 deficiency, because vitamin B 12 only exists in animal foods and yeasts, such as eggs, milk, fish, shellfish and meat.

Fermented stinky tofu is not only rich in vitamin B 12, but also can help promote human metabolism and maintain the health of nervous system. In the fermentation process, plant lactic acid bacteria beneficial to gastrointestinal function will also be produced. Although moderate consumption is beneficial to human health, the cooking method is limited to steaming, not high-temperature frying.
