How To Try the Low-Histamine Diet

5. Foods to Avoid: Fermented Foods

Fermented foods are among the highest in histamines. Avoid soy sauce and miso, sauerkraut, pickles, kefir, and buttermilk, as these all contain high levels of histamine. Microorganisms convert histidine into histamine during the fermentation process, so these foods should be avoided by people with histamine intolerance or sensitivity.

Alcoholic beverages fall within the same category. In addition to beer, wine, and cocktails, avoid vinegar and kombucha, as these drastically increase the body's level of histamine.
