Scientists "planted" roundworms on a diet to study thoroughly what happens in the body with a deficiency of vitamin B12. According to them, a similar lack of this vitamin is experienced by a large number of the world's population.
So, according to the results of the study, a lack of vitamin decreases the ability to metabolize branched chain amino acids (also known as BCAAs). This, in turn, leads to toxic accumulation of partially metabolized BCAA by-products, which damage mitochondrial health.
Due to damage to mitochondria, the risk of infection with at least two deadly pathogenic microorganisms increases: Pseudomonas aeruginosa and fecal enterococcus. However, according to Rice University staff, the number of dangerous pathogens to which susceptibility is growing due to a lack of B12 may be even higher. Research in this area will be continued.
As you know, vitamin B12 deficiency can be fraught with other negative consequences, including some types of anemia, death of nerve cells and depression.
The highest concentrations of vitamin B12 are in beef and pork liver, chicken heart, octopus, smoked herring, mussels, mackerel, as well as in other products of animal origin. Most people who are deficient in this vitamin are vegetarians, as it is almost impossible to make up for it with herbal products.
