Fermented Foods for Gut Health — https://www.umassmed.edu/nutrition/blog/blog-posts/2019/6/fermented-foods-for-gut-health/
I’ve spent some time at the request of a reader to list the top fermented foods for gut health. Many websites have very similar lists. If you’re interested in learning more about what some of these foods are the Healthline article 8 Fermented Foods and Drinks to Boost Digestion and Health is a decent source. https://www.healthline.com/nutrition/8-fermented-foods
But if you really want to learn about fermented foods you’ll never eat because you won’t find a store nearby that carries them read the Wikipedia article https://en.wikipedia.org/wiki/List_of_fermented_foods
Although I think I can get Bánh cuốn at the Vietnamese grocery store.
The take home lesson is simple. Find a few fermented foods you enjoy eating and eat them often. Beet Kvass? No thanks. I’ll stick with yogurt, pickles, and sauerkraut.

This is great info. Thank you so much for posting. I’m going to study it carefully. I do like pickles. But I have never found any packed insult. Also have to think of my blood pressure. I’m probably going to be going with Kiefer and yogurt. But I’m interested in the cheeses. I will have to research that more. What exactly should I look for on the label? Any particular kind of cheese?
