Is Coffee Safe for SIBO?
Black coffee itself is low in FODMAPs and can actually benefit methane-dominant SIBO by stimulating gut motility. However, coffee increases stomach acid production and gut motility, which can worsen diarrhea in hydrogen-dominant SIBO. The main risk comes from additives — regular milk, cream, sugar, and flavored syrups.
