Interesting findings of American scientists. During a series of tests they proved that vitamin A has a great impact on the immune system of the child. It is particularly interesting that this substance exerts its positive influence, beginning with fetal age, and continues to act even in adolescence, writes the journal Nature.
Findings are made after conducting research involving laboratory of pregnant mice and their offspring. It turned out if pregnant laboratory mice did not receive vitamin A, it and the offspring could be found serious defects in the lymphoid organs, which normally provide the immune response in all mammals.
As a result, mice with vitamin a deficiency was often ill with infectious diseases. The received information, scientists believe, can be extended to humans, because the mechanisms of the immune system in all animals alike.
