Vitamin B12, also known as cobalamin, is an essential nutrient for the human body. Its main physiological function is to participate in the manufacture of red blood cells in the bone marrow and prevent pernicious anemia; it prevents the destruction of the brain nerves. The lack of vitamin B12 can cause a lot of harm. Some people say that eating dark vegetables can supplement vitamin B12. Is this true?
What are the risks of vitamin B12 deficiency?
Vitamin B12 is generally known as a hematopoietic vitamin and has a superior effect of skin regeneration. Both of cell regeneration and hematopoiesis are indispensable, and it is an important component for promoting human metabolism.
The symptoms of anemia caused by vitamin B12 deficiency include: indigestion, thin yellow hair, dizziness, lack of energy, vomiting, diarrhea, irregular menstruation of women, and yellowing of eyes and skin. Severe liver dysfunction may also occur, memory loss, decreased resistance, body hematopoietic disorders, and even unbalanced actions, the body has intermittent pain in an uncertain position, sore fingers and toes and so on.
When it is particularly lacking, the growth of intestinal surface tissue, bone marrow cells, and other regenerative and rapid cell growth will be affected, and at the same time, it may also affect the nervous system. However, the mechanism of action is not exactly the same as the deficiency of folic acid. Therefore, in treatment, the two cannot replace each other.
Vitamin B12 and folic acid are commonly referred to as hematopoietic vitamins. Pregnant women, infants and children, the elderly, and people with gastrointestinal diseases may have excessive vitamin B12 consumption, limited intake, or poor absorption and utilization. It is easy to cause the deficiency of vitamin B12 in the body. Therefore, this group of people suffers from anemia and has a high rate of delirium.
Does eating dark vegetables supplement vitamin B12?
Vitamin B12 in nature is mainly synthesized by the bacteria in the rumen and colon of herbivores. Therefore, it is mostly found in animal foods, mainly liver and meat, and dairy products also contain a small amount. Such as animal liver, kidney, beef, pork, chicken, fish, mussels, eggs, milk, cheese, dairy products.
Most vegetable vegetables do not contain vitamin B12, and dark vegetables have no scientific basis for vitamin B12 supplementation. If it is a strict vegetarian who does not eat even egg-milk, it is recommended to eat more beans. The root nodule of some beans contains parasitic microorganisms that can produce a small amount of vitamin B12, and if necessary, can take nutritional supplements.
