Just the last six months or so I've seen educated people posting in my feeds about how fiber might just be included in foods that are beneficial, with fiber itself not being so.
Well, not that it matters for me since I have Crohn's and can't really eat fiber at all.
- if not fed right, these bacteria may consume gut mucus, causing inflammation
- when fed right, they actually improve digestion efficiency
thus, in theory, proper diet can get you from chronic diseased [with the usual western medicine prescriptions] to healthier+more energetic
