I have celiac but that's the least of my problems. I and several family members cannot tolerate starches. starches from fruit and vegetables seem to be ok if balanced with protein. Yet even on this diet in the fall I have confusion, memory loss, speech problems etc. Is this associated with yeast overgrowth. I know I'm sensitive to yeast but I don't have rashes or skin itching except for the base of my scalp which is also worse in the fall. I thought this was psoriasis.
