Vitamin B12, the mysterious power that protects the brain.

With an ageing population, dementia has become a global public health concern. In China, the prevalence of Alzheimer's disease is increasing year by year, which has brought a heavy burden to families and society. How to prevent dementia in daily life has become a common concern. Recently, an authoritative study found that eating foods rich in vitamin B12 can reduce the risk of dementia. In this article, we'll reveal how vitamin B12 supports our brain health.

1. The importance of vitamin B12.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is essential for human health. It is the basic raw material for the synthesis of DNA and RNA, participates in the production of nerve myelin, and has a protective effect on the nervous system. At the same time, vitamin B12 is also involved in a variety of physiological functions such as red blood cell production and maintaining intestinal health.

2. The relationship between vitamin B12 and the risk of dementia.

A recent study published in the Journal of the American Medical Association (JAMA) found a strong relationship between vitamin B12 intake and dementia risk. The study, which followed more than 2,000 older adults for 10 years, showed that participants who did not consume enough vitamin B12 had a significantly higher risk of dementia.

Studies believe that the role of vitamin B12 in reducing the risk of dementia is mainly reflected in the following aspects:

1.Protects nerve cells: Vitamin B12 can maintain the normal function of nerve cells, reduce neuroinflammatory responses, and delay neurodegeneration.

2.Promotes nerve regeneration: Vitamin B12 promotes the production of nerve myelin, which helps in the repair and regeneration of damaged neurons.

3.Improves cognitive function: Vitamin B12 is involved in the synthesis and metabolism of neurotransmitters, which helps improve cognitive function and prevent dementia.

3. How to get vitamin B12 through diet

Vitamin B12 is mainly found in animal foods, especially meat, seafood and eggs. Here is a list of foods rich in vitamin B12::

1.Lean beef: Contains about 25 mcg of vitamin B12.

2.Lean pork: Contains about 19 mcg of vitamin B12.

3.Fish: Deep-sea fish such as salmon, tuna, mackerel, etc., are rich in vitamin B12, containing more than 20 micrograms per 100 grams of fish meat.

4.Eggs: Eggs contain about 50 mcg of vitamin B12.

5.Dairy products: Dairy products such as milk, yogurt, and cheese also contain a certain amount of vitamin B12.

6.Mushrooms: Some mushrooms such as shiitake mushrooms and fungus contain small amounts of vitamin B12.

It is recommended that everyone diversify their daily diet and consume foods rich in vitamin B12 in moderation to protect brain health.

4. Precautions.

While vitamin B12 has a positive effect on the prevention of dementia, excessive intake may also lead to adverse effects. In general, adults need to consume 25 mcg to 10 mcg of vitamin B12. The following groups of people should pay special attention when consuming vitamin B12:

1.Patients with diseases such as hyperthyroidism and abnormal oxalate metabolism should consume vitamin B12 in moderation under the guidance of a doctor.

2.Patients who have been taking antacid drugs, anticonvulsant drugs and other drugs for a long time should pay attention to monitoring vitamin B12 levels to prevent deficiency.

3.Special populations such as the elderly and vegetarians should pay attention to vitamin B12 intake to prevent deficiency.

In conclusion, maintaining a balanced diet with moderate intake of foods rich in vitamin B12 can help reduce the risk of dementia. At the same time, paying attention to one's own physical condition and seeking medical treatment for related diseases in time is also an important measure to prevent dementia.
