Tackling SIBO or dysbiosis often takes care of food intolerances.
If your immune system is at play, digesting foods poorly will make food intolerances worse. We recommend that you try:
Digestive enzymes
Enzymes are necessary to break apart chains of amino acids so proteins are completely digested. Effective digestive enzymes include pepsin, bromelain, proteases, and more.
Immune system support
Certain flavonoids (beneficial plant compounds) have been shown to help block the immune response. They include quercetin, luteolin, apigenin, and lycopene [Source: PubMed].
