Compared with the refined cereal period, the Himalaya 292 diet produced a 33% increase in faecal weight, a lowering of faecal pH (from ~7.24 to ~6.98), a 91% increase in faecal butyrate excretion, a 57% increase in total faecal short-chain fatty acid (SCFA) excretion, and a 33% reduction in faecal p-cresol concentration (a putrefactive metabolite). These changes are interpreted as improved bowel-health indices: greater stool bulk and increased production of beneficial SCFAs (like butyrate), supporting colonic health and favourable gut environment compared with refined cereal or even whole-wheat diets.
