Somehow, the differences for me when going Paleo/whole foodism werent/arent really dramatic. Sure, I have less eczema and less dandruff in my face, less bloating, no diarreah but not near cured by my diet at all. Maybe im less depressed or hysterical, cant tell for sure. Supposedly gluten or casein etc are to blame to certain disturbances in people with autistic guts like me. I think the trend of assuring diet can cure your ailments its inflated and untrue. Diet its just part of the healing, but wont cure serious disorders in my opinion.
Im taking vit D 10000 ius per day since more than a month and havent noticed a thing, but I know its good for me since im defficient.
