Eating fiber doesn’t just boost the microbiota. A team from Stanford has shown how the fatty acids derived from it influence the gene expression of intestinal cells, a process essential to digestive health.
We know their benefits on satiety, blood sugar regulation, the microbiota… But dietary fiber does much more than that. A study from Stanford University of Medicine, published in Naturehighlights hitherto unobserved benefits for… the regulation of our genes. After their consumption, the intestinal microbiota produces short fatty acid chains, which themselves impact gene expression. “ We learned, for the first time, how fiber really works : they change the expression of key genes in the intestine », Says researcher Michael Snyder, professor of genetics at the Stanford University School of Medicine. “ In this study, we directly used human cells to examine how fibers influence gene expression », Specifies the researcher.
We are not strictly talking about genetics, but about epigenetics. “ This refers to all the mechanisms…
