Thanks, Kristine. It's frustrating that many aren't aware how powerful an effect healthy eating and lifestyle can have on well being. Yes, we know it can improve metabolic health, and along with improved metabolic health comes a variety of benefits with improved mental health being at the top of the list. I'll check out Dr. Chris Palmer's recent work.

ETA: Pre-ordered his book to be available in November, Brain Energy. Just from the description, the pharmacology portions of it seem to fit hand-in-glove with Dr. David Healy's books, Shipwreck of the Singular and The Decapitation of Care, but it's much more from a lifestyle-change emphasized perspective.
