I recently returned from a 2 week vacation and my digestion hasn't been right. Nothing uncomfortable or concerning, but abnormal for me. I was backpacking and camping so my intake of fresh foods was almost zero, and I suspect this threw my gut bacteria out of whack. I think I can just return to my normal foods and things will sort themselves out, but it got me wondering. Will any probiotic work well for a WFPB diet, or will we benefit more from a particular kind? Are some probiotics non-vegan? What are your thoughts on probiotics in general? Are they necessary or beneficial? Do you take them? What kind? I have some probiotics at home but I stopped taking them a couple months ago because it didn't feel necessary and I thought that continuing to take them may do nothing more than upset the natural equilibrium . "I Contain Multitudes" by Ed Yong has been on my reading list for a while now...have any of you read it? Any other good sources of information on the subject?
