Yes, it is speculative, but based on sound logic I hope. I'm really asking whether my speculations have any basis in experience for anyone else.
In terms of protein digestion, I've deduced this based on the following:
- That the problem appears when I eat proteins
- That there is a sliding scale depending on how hard to digest the protein is, e.g. fish easiest, beef hardest
- That the problem is worse when I eat larger portions of protein
- That the problem can be alleviated by boosting stomach acid, which suggests it's digestion related
- That I have problems with other indigestibles, e.g fruit skins, and the symptoms are similar
I've basically self-diagnosed myself with a kind of SIBO of the Stomach (although SIBO itself might also be a problem), and i'm trying to validate it now with a few experiments.
I'll defiinitely lay off probiotics, and I've also stopped all lacto-ferments, including cheese just in case.
I did a rough and ready experiment last week that did seem to back up my theory, involving alcohol (although I'll have to add a 'don't try this at home' warning).
I'd read on some brewers websites that lactobacillus can't survive more than a 20% concentration of alcohol, so to replicate this in the stomach I measured out 100ml of gin and drank it before bed for 2 nights in a row. It worked, and my digestion improved a lot for a few days, but has now reverted to it's previous state a week later. It's clearly not a good long term strategy but it does seem to back up the theory.
Anyway, thanks for the advice, and wish you all the best with your own efforts.
