Have a reference for this? Seems implausible, bacterial fermentation of any sugar in the intestines should result in distress, i.e. the same symptoms a lactose intolerant person would have upon drinking milk.
- ncmncm 5y agoFermentation is not the principal pathway by which bacteria process sugar. In particular, sugar is a key raw material for growth, when available. LMGTFY: https://duckduckgo.com/?q=bacteria+sugar+pathway https://duckduckgo.com/?q=bacteria+sugar+pathway
- phonypc 5y agoUhh... sure. If you don't want to call it fermentation that's ok. Though I don't imagine human gut bacteria are respirating, or some other more exotic form of metabolism. Point is, the products of bacterial metabolism of sugar in the human gut tend to cause issues, as in lactose intolerance, or the more rare sucrose intolerance. Hence my request for a citation on fibre delaying absorption of fructose so that "bacteria get most of it".
- ncmncm 5y ago"Raw material for growth" means actually using the carbons to make the molecules that the daughter cells are made out of. So, not fermenting, and not respiring either. I am only passing on what Robert Lustig, who is in a position to know, reports. You would have to ask him.
- phonypc 5y agoHow do you imagine the carbon makes it from the sugar and into the components of new/larger cells? Magic? It has to be metabolized first. In the gut, mostly through fermentation.
