Scientists from Japan, studying the effect of fatty acids on the human body, have established a relationship between the intake of these substances into the bloodstream of a pregnant woman and the development of the brain of an unborn child. The results are published in the publication "Stem Cells".
Omega-3 and Omega-6 are not synthesized in the body of mammals and come only from food. Performing important functions (delivery of oxygen to the tissue, protection of cell membranes and energy deposition), acids are indispensable.
The source of omega-6 acids is vegetable oils. Omega-3 acids are predominantly found in marine fish, the presence of which in the diet is important for the normal course of pregnancy, reducing the level of post-natal depression and brain development in a child in the first year of life.
To study the effect of the lack of omega-3 and the imbalance of fatty acids on the body, a group of scientists from Japan, led by Professor Noriko Osumi, conducted an experiment in which pregnant rodent laboratory females received food with a predominant content of omega-6, but low Omega-3 levels. This altered fatty acid ratio is common in people’s diets. For the purity of the experiment, the second group of pregnant females, scientists fed a balanced.
The researchers found that the brains of rats whose mothers received mostly Omega-6 were much smaller than the brains of the young whose mothers ate balanced. The rat pups from the experimental group had certain abnormalities in emotional behavior. So, despite the fact that after birth, the rodents received proper nutrition, they had anxiety at a more mature age.
After studying the metabolism of the developing brain of rodents, scientists were able to say that it is the metabolites of omega acids that are an important foundation for the growth of stem cells.
Rats that received predominantly omega-6 during pregnancy, stem cells had a higher rate of development, which increased the production of omega-6 oxide, which stimulates the early aging of neurons.
The authors of the scientific work believe that the results clearly demonstrate that an excess of omega-6 acids with a lack of omega-3 causes abnormal brain development.
