It sounds like your biggest problem is the leaky gut syndrome from which all the allergies are stemming. It also sounds like you really need the foods you mentioned since there are so many on the diet that you can’t eat. My advice would be to concentrate on healing the leaky gut syndrome more than anything else. If you’re not taking either digestive grape bitters or Swedish bitters plus a high dose of probiotics and kefir, I would start both of them right away.
Swedish Bitters are sold on Amazon:
