ED: Can't reply because of rate-limiting. So;
It breaks down a bit differently. Foods which are gluten-free are quite different in several ways. There are a lot of unhealthy things I avoid while also avoiding gluten.
I think that short carbs influence the dopaminergic system which intestinal health influences the serotonergic system. Both are feel-good hormones. I suffer from chronic depression which seems to mean permanently reduced levels of one or both of these. I'm an 80s kid, meaning my formative years happened during a time which was crazy on many levels. I don't have diabetes, fortunately. Aside from chronic depression I'm in very good health.
Take this as you will.
