Hello Giorgos
That's very interesting (methionine). Unfortunately, I have yet to see this in my research adventures, but I will keep a lookout for anything that does come out.
As for meat consumption, it did say that low amounts of protein were ok. However, eating zero protein is not good since it increases malnourishment.
It's no wonder the Mediterranian diet is so beneficial, not only for us Greeks but for everyone 💙😀
