A troubled intestine can send signals to the brain, just as a troubled brain can send signals to the gut. It is also supposed that oligofructose accelerates lipid catabolism [157]. The selection of probiotic strains, prebiotics, and their respective dosages is crucial in obtaining a therapeutic effect, so separate sections are dedicated to this topic.
