Yes, fermented foods can be problematic for people with histamine issues. However, not everyone with an autoimmune illness or chronic illness has histamine intolerance. Improving one's gut health can often help improve histamine tolerance. For someone with histamine intolerance who is working to improve gut health, taking an oral probiotic and rotating the strains regularly can help increase the diversity and quantity of beneficial bacteria in the gut. Working with a medical provider and dietitian who are trained in gut health can be very helpful in the journey of improving histamine intolerance.
