New Delhi, 27 Jan (ANI): A new study describes that what we eat are responsible for our gut bacteria which has a significant impact on behavior and brain health. The study presents the most up-to-date understanding of the relationship between the proteins produced by intestinal bacteria and the human central nervous system and explores the various mechanisms through which the microbiome can influence the brain: by stimulating and over-stimulating the immune system, releasing hormones identical to those made by the human body, or through stimulation that sends signals to the brain. The new study describes many ways gut bacteria could impact normal brain activity and development, affect sleep and stress responses, play a role in a variety of diseases, and be modified through diet for therapeutic use.
