Whats the point of fermented foods?

What good are fermented foods if the only species they usually provide are lactobaccilli. Lactobaccilli species only provide relief from extreme conditions or diseases such as diarrhea, crohns, ibd, ibs. But do they really restore the gut flora. I'd imagine that consuming fermented foods may even lead to SIBO even if someone's immune system is functioning normally. I'm not even sure how the bacteria would reach the colon. The journey through the GI tract is an extremely long one and I would imagine that probably half of the bacteria wouldn't survive the gastric acid in the stomach. Probiotics themselves seem useless too. There's one particular probiotic known as Prescript Assist that claims to have Soil Based Organisms and it contains bacteria that closely resemble our natural flora but I still don't know how that would reach the colon without expelling its contents in the small intestine. The only treatment with promising results seems to be fecal transplants.

You do make some valid points but if were adding species that our guts are not accustomed to what good is it? Is it really restoring the flora?

"personally i avoid them myself"...i should clarify that it is fermented 'veggies' that i currently avoid. i do eat fermented dairy such as, yoghurt, kefir yoghurt, sour cream...because i like the taste (not a big fan of the taste of cheese tho).

Sure that MIGHT work but whats the point when lactobacillus and most other bacteria found in probiotics and fermented foods hardly make up the bacterial population in the colon?

"I would imagine that probably half of the bacteria wouldn't survive the gastric acid in the stomach."

Good thing there are probably on the order of 10^7 bacteria per mL in fermented foods. Even if 90% are destroyed you still have 10^6 bacteria per mL entering the intestine. If you kill off 99.99% of the probiotic dose, you still have 1000 bacteria per mL surviving, more than enough to "infect" you. Worth pointing out that the infective dose for pathogenic GI bugs is around 10^3-10^5 bacteria, that's also a mere 1000 bacteria.

As for the concern over SIBO… SIBO occurs not because the small intestine is dosed with probiotics or pathogens, but rather because the immune system is not functioning properly and creates an environment where SIBO can occur.

"What's the point of fermented foods?"

  • aren't they suppose to keep/store longer?
  • some are a good source of Vitamin K2?
  • some people like the taste & use as a condiment.

personally i avoid them myself, did try for a while, & as we most things i try for the first time, probably went way overboard. i think i may be susceptible to high histamine levels & from what i have read, fermented foods are either high in histamine or histidine, &/or have the effect of raising histamine in the body.

My own unscientific personal theory is that the fermented foods help in the healing process and gut health. This allows the other more natural good bacteria to grow and do the job.

Try taking some potato starch raw with yogurt or kefir, this will help get it to the colon - maybe.
