By contrast the finding that well-trained muscles protect against depression by a mechanism involving breaking down kynurenine peripherally and thus preventing it from entering the brain is both new and in my opinion very exciting. After the fact it makes sense, but I would not have predicted it.
Incidentally, kynurenic acid in the brain is also implicated in schizophrenia, which makes me wonder if this will have explanation value beyond depression as well.
I find this an unexpected and delightful discovery.
