Sure - I've also been growing more sensitive to the mental / emotional effects of diet. And generally spekaing, according to new scientific studies, it actually seems that the digestive system and bacterial fauna inside the gut are playing a big role in regulating our emotional balance.

But I haven't been writing that much about this topic, as I think that there are other writers out there who are more educated about these things. Personally I've been going more and more to simple diet - food cooked on local raw materials etc. But then, I also feel that constant overdose of sugars and carbohydrates is not good, not even if they are all locally and organically grown. So, nowadays I eat less potatoes and wheat, not because some theory says so, but because that's how I feel when I listen to my bodily sensations and intuitions =)
