Yeah, I'm not familiar with Valter Longo, but that diet does pretty well match up with what I'm trying to do. I might be a little high on the protein, when I'm making seitan regularly...it's roughly equivalent to meat in protein content, and as with most things I enjoy I tend to eat a lot of it when I cook it. I'll have to do some more reading about what the science says about vegetable proteins like seitan and tofu.
