B vitamins – benefit or harm?
- B vitamins have an important role in metabolism – they are involved in energy production, are involved in tissue respiration. This is a common effect of B vitamins, and each vitamin separately has its own special effects on the body.
- For example, vitamin B1, or thiamine is involved in energy metabolism, i.e. with the help of the body receives the energy from carbohydrates, fats and proteins.
- Vitamin B6 or pyridoxine is involved in carbohydrate metabolism and in the synthesis of hemoglobin regulates the activity of the nervous system involved in the regeneration of erythrocytes.
- Vitamin B12 is cyanocobalamin or affects the development of the nervous system, and affects the production of erythrocytes.
- In addition, the B vitamins protect the walls of blood vessels. This is due to the fact that they are able to reduce the content of homocysteine in the blood
Homocysteine is a product of the amino acid methionine. Forming in the body, it begins to destroy the walls of blood vessels, resulting in formation of the vessel wall breaks, which the body begins to “plug up” with fat. This “treatment” leads to atherosclerosis, narrowing or completely occluded vessel lumen. This may result in rupture of blood vessels, heart attack, stroke.
- B vitamins on homocysteine rescue vessels, or turning it back into methionine (under the influence of vitamin B12) or the next product of processing (under the influence of vitamin B6).
But this beneficial effect vitamins have a healthy body. But a person with diabetes these vitamins have a negative impact. Previously it was thought that diabetes these vitamins are useful and they are always administered in the treatment of diabetes.
But recent studies have shown the following.
According to Australian scientists in people with diabetes, the use of vitamins B6 and B12 increases the risk of strokes and heart attacks.
American scientists in their studies revealed a negative effect of B vitamins on the kidneys.
The kidneys of patients with diabetes can not cope with deducing from the body of vitamins, vitamins accumulate in the body and reach toxic levels.
Therefore, scientists do not recommend the use of B vitamins in patients with diabetes.
