Hello again s.s.. Well, I am sensitive to a lot of different molds, and therefore have to avoid fermented/aged foods too. I also cut down on my sugar intake. My allergist said that bakers yeast is different than fungal yeast, and that cutting out that may not help. Cutting down on a lot of carbs does seem to help. I know they slow my system down, and that contributes to more bloating and gas.Also, it is not uncommon for the colon to become sensitive after long-term antibiotic use, as in my case. I was found to be sensitive to benzoic and citric acid as well as dairy whey. They cause bloating and abdominal discomfort in me. I can get cramping and frequent soft-stooling the next day.Food and chemical sensitivities can follow infections of the bowel and cause more bowel irritability. It would not surprise me that fibro-fog may also be connected with those sensitivities. I would think it is much like people who find certain foods/chemicals trigger their migraine headaches.
