What to know about kefir

Kefir is a cultured milk drink that gets sold as a gut-health hero, which is exactly why its trigger profile surprises people. The long ferment with dozens of bacteria and yeasts builds up histamine and tyramine, so kefir is high in both, and because it starts as milk it is also very high in lactose and carries the same casein and whey dairy proteins. If you tolerate probiotics but still react to kefir with congestion, flushing or gut upset, the fermentation and the dairy are usually why.

Watch for

  • High in histamine because it is a long, mixed-culture ferment, so it can cause flushing, headache or a runny nose even in small glasses
  • High in tyramine from the same fermentation, which matters if you take an MAOI or are prone to fermented-food headaches
  • Very high in lactose, so it commonly triggers bloating, gas and cramps in anyone lactose intolerant
  • Carries casein and whey dairy proteins, a separate issue from the histamine and the lactose
