New Study Shows Importance of Vitamin B12 in Supporting Nervous System and Cell Growth
A new study has highlighted the crucial role that vitamin B12 plays in our bodies, particularly in supporting the functions of the nervous system. The study, conducted by researchers at the German Society for Nutrition (DGE), found that vitamin B12, also known as cobalamin, is essential for the formation of red blood cells and the DNA, which contains our genetic information.
In addition, vitamin B12 plays a key role in the growth and division of cells, as well as supporting the regeneration and new formation of the sheaths of nerve fibers, which are crucial for the proper functioning of the nervous system. The study also revealed a close link between the metabolism of cobalamin and the vitamin folate, with vitamin B12 converting inactive folate into its active form while reducing levels of the amino acid homocysteine, which is a potential risk factor for cardiovascular disease.
While the importance of vitamin B12 is clear, our bodies are unable to produce it naturally. Therefore, it is essential to obtain enough vitamin B12 through our diets. The DGE recommends a daily intake of four micrograms of vitamin B12 for young people from 13 years and adults. Pregnant and breastfeeding women have a slightly higher requirement, needing 4.5 and 5.5 micrograms per day respectively.
So, which foods are the best sources of vitamin B12? Animal products are the primary sources of cobalamin. Beef, chicken, salmon, and oysters are particularly rich in vitamin B12. Other sources include lamb leg, pork escalope, mackerel, herring, and dairy products like milk and cheese.
For those following a plant-based diet, getting enough vitamin B12 can be more challenging. While some plant foods contain small amounts of vitamin B12, such as certain seaweeds and fermented vegetables, the DGE states that it is not possible to meet the vitamin B12 requirement exclusively through plant-based foods. Vegans and vegetarians are advised to take vitamin B12 supplements to ensure they meet their nutritional needs.
Not getting enough vitamin B12 can lead to deficiency symptoms, which can develop gradually over time. Some common symptoms include fatigue, weakness, anemia, difficulty concentrating, tingling and numbness in the arms and legs, and even damage to the nervous system if left untreated. Therefore, it is crucial to include sufficient vitamin B12 foods in our diets or to supplement when necessary.
In conclusion, vitamin B12 plays a vital role in supporting various processes in our bodies, particularly the functioning of the nervous system and cell growth. While animal products are the best sources of vitamin B12, those following a plant-based diet should consider taking supplements to ensure they meet their nutritional needs. With adequate intake of vitamin B12, we can support our overall health and well-being.]
