What is this special nutritional niche that yogurt occupies? The majority of humans don't eat it and seem to be doing ok.
But there other fermented foods one can eat that are dairy-free, like tempeh, kimchi and miso.
Found also the best representative (to me at least) yogurt at Whole Foods - yes, it's marked "Bulgarian", and it's pretty good :)
I'm also following low-carb/keto diet, so while I like it, I have to be careful with it, though it's much better (cheat) than other things... (like ... pastry)
