Like your blog, some good ideas / angles. I've found most of the stuff on nutritional psychology comes from Australia, including a guy called Jurrian Pleissman, and also this
Hypoglycemic Health Association of Australia
I used to think that Hypoglycemia was a kind of hypochondriacs thing, but it turns out that this was me for 34 years - eating a lot of refined sugar and getting low blood sugar, with the depressions and body clock disruption. The questionnaire on this website really opened my eyes.
Obviously the primal/paleo community agree with this, but generally in the UK at least, medical treatment for depression pays no attention and I think its a massive issue - causing a lot of unhappiness.
