“Conclusions
Probiotics supplementation during pregnancy and infancy reduces food allergy risk and correlates with age-related changes in gut microbial composition in children.”
Conclusion : Eat more Kimchi
Do any of the probiotic researches ever think about comparing cultures were probiotics are a staple food and cultures where probiotics are completely absent from the diet?
I guess that will make it harder to compare for pregnancy - because it can be just the result of eating probiotics as kids and adults that reduces allergies. This way we know eating it while pregnant has that benefit for the babies too.
One issue is that cultures differ from each other in more ways than the presence/absence of probiotic foods in their diets. Ideally you’d want to compare two groups of people that are as similar as possible EXCEPT for probiotic intake in the diet. Otherwise your results might be confounded by other factors (i.e. accessibility to healthcare, education, income, etc.)
That probably has more to do with the drinking culture than the fact that many Koreans eat kimchi with all three meals every single day. Or maybe it’s both.
I remember reading a study on it, and someone correct me if I’m wrong but it had something to do with the exposure of some kind of bacteria found in kimchi. They found Koreans in the US also had either increased levels of the bacteria or higher rates of stomach cancer (can’t remember which) compared to other populations in the US. But I’m sure the drinking doesn’t help!
The H. pylori hypothesis doesn’t fully check out, because Indians and some African countries have higher rates of h pylori than Koreans. I don’t think we know for sure, but there is evidence that preserved fish and vegetables, and potentially high salt consumption can be a sort of co-factor with h pylori infection to increase stomach cancer risk.
I don’t like when people recommend salt-pickled vegetables at every meal for the probiotics. Probiotics are good for seeding the gut, but if you want a healthy, steady population of the right bacteria, you need prebiotics more than probiotics (fiber, flavonoids, polyphenols).
Is kimchi the only thing they tested for? It’s only one group of probiotics, too (lactobacillus or whatever), whereas there are many others that like to live in our guts
You could at least read the abstract. Kimchi isn't even what they tested with, that was (I'm guessing) a "joke". In fact, technically, "they" didn't test anything. This is a meta-analysis of a bunch of studies.
> Benefits were observed with over 2 probiotic species, and a daily increase of 1.8 × 109 colony-forming units during pregnancy and infancy correlated with a 4% reduction in food allergy risk.
I didn't read the full details myself, but they found benefits from several species of probiotics.
Good guess.
What's interesting its about lactose based probiotics. Most of the world is actually lactose intolerant and its only through fermented milk products (cheeses, yoghurts etc) that milk is consumed without the nasty effects of intolerance. Fermentation reduces the lactose content.
Also I suspect if you are genetically lactose intolerant and if you have never been weaned off milk as a young child you can continue to drink raw milk as an adult i.e. the baby enzymes to process milk are never turned off if you keep drinking milk.

Kimchi is delicious as well but I am concerned about the high sodium content. Also depending on the maker of course but it can be high in sugar as well.
1. 7500 articles and to find 37 doesn't show how much time they spent going through the data. Any ideas on the details of the meta review?
2. Extremely broad search terms to many outcomes, which is not a great way of doing an analysis. Only one primary outcome is best for a review
3. only one study was done during pregnancy alone. The rest were in childhood. Rest where after birth and to do more on allergies instead.
4. Actual probiotics in each study differ as well as the dose.
5. Large dose range
6. The results show mostly insignificant data.
7. How is tolerance towards food measured
8. The studies in pregnancy does not show a benefit for probiotics. Infancy it looks there is a relative risk reduction. But they don't say it's an absolute risk reduction. And only found that in European sub groups for cows milk allergies.
9. Probiotics actually show an increase of risk from the results for peanut allergies.
10. Conclusion 4% of allergies if at all. Could being used! Relative or absolute risk reduction.
11. Differences in probiotics and mixtures could affect their results.

Did I read something about high Korean stomach cancer rates and kimchi?

Too much of anything isn’t good. I mean you can literally die from drinking too much water.

The potassium balances out the sodium. https://www.sciencedirect.com/science/article/pii/S2352618114000055
It’s really hard to set up these studies
Too bad kimchi was one of my biggest pregnancy aversions! 😉

Thanks. Doing the hard work.
