GMO Food Failures
I specialize in food sensitivities where certain foods and chemicals are tested for a loss of oral tolerance (a fancy way of saying food sensitivity). I’ve seen certain chemicals cause headaches in people. Today I had a patient that determined by a methodical food challenge/washout process that she can eat a non-organic apple only if it is washed very well, otherwise she will get a headache. Although not certain we can assume it is the pesticide residues on the skin of the unwashed apple as many people are reactive to chemicals. (and do not realize it!)
