Interesting! I frequently have foggy headed mess and I seem to get GI issues flaring up every time I go on a run. I’ve always thought the foggy head was from my medication, but I am vegan so I eat a lot of soy products. So this whole thing just has me wondering…

I ask about tempeh because it’s fermented soy, which many people report does not cause any of the intolerance reactions of regular soy. It would be interesting to compare the two.
