An international group of scientists undertook to answer this question. As a result of a number of studies and experiments, they came to the conclusion that the connection between diet and immunity “flows” through the intestinal microflora.
So, having analyzed the experimental mice, experts found out that the production of by-products of the metabolism of microbes living in the intestine depends on the diet. And this, in turn, affects the immune defense.
Experiments in mice with ulcerative colitis demonstrated that those who received branched-chain liposaccharides fared much better than those who did not receive nutritional treatment.
