We're told water at meals dilutes digestive juices, that a yoghurt is enough to fix the microbiota, and that reflux always means too much acid. The reality is physiological: chewing, vagus nerve, plant diversity, gut mucus, between-meal motility. Ten questions, a few traps, few mantras. Level 1: water at meals, the yoghurt that "rebuilds" the microbiome. Level 2: tool confusions — a generic probiotic versus a documented strain, reflux treated as excess acid when motility is the issue. Level 3: the migrating motor complex between meals, Cajal cells, and plant diversity — thirty plants a week rather than one ferment. To dig deeper: the gut as an electric instrument (Cajal, NTS, digestive jet lag) and the SIBO / SIFO / IBS exploration. Sources: Gastroenterology, Cell, NEJM, Am J Gastroenterol.
