Over a decade ago I read Candace Pert's Molecules of Emotion, but didn't connect the dots: what we ingest (food as much as pharma) affects emotions. One year ago I embarked on a diet to lose a few pounds and chose the paleo 'diet' ... not a diet in the contemporary sense of the word any longer. Now a way of eating. In my n=1 experience, it's astonishing how much food and its nutritional attributes have affected my emotional and mental state. Going from thpughts of suicide, chronic low level depression, minor self mutilation (decades of nail biting--chewing the nail & cuticle until bleeding; scratching dry skin until bleeding; attacking acne with a vengeance) ... to a ridiculously positive mood :-) beautiful nails and skin, and a love of life I've never experienced before. Ever. Do I attribute this to giving up wheat, dairy, soy, sugar, etc., and adding omega 3 fat, characteristic of eschewing a modern diet? Yes. I'd tried pharma, tried specific supplements, tried professional counselling, tried everything short of voodoo. I whole heartedly believe there's a brain/mind-body connection between the gut and the brain, and there's nothing to lose for someone to alter dietary habits for a few months to see if he/she may benefit. A doctor wouldn't hesitate to recommend a drug to 'see if it helps' ... why not altering the diet to 'see if it helps'? Goodness knows, there's no side effects from Not Eating French Fries. I know this is 100% anecdotal and not empirically tested, but I feel compelled to let other people know there's a way to feel wonderful without drugs.
