What to know about sauerkraut
Sauerkraut is the clearest example of the gut-health paradox: a food promoted for the microbiome that is actually very high in histamine. Fermenting the cabbage generates histamine and tyramine, and aging it also concentrates salicylates and free glutamate, so sauerkraut can trigger flushing, headache or gut upset in sensitive people. Unlike kimchi it has no chilli and no garlic, so if plain fermented cabbage still bothers you, the histamine, tyramine, salicylate and glutamate from the ferment itself are the likely reasons.
Watch for
- Very high in histamine from fermentation, a frequent cause of flushing, headaches and congestion despite the healthy-food reputation
- High in tyramine, which stacks with the histamine and matters on MAOI diets
- High in salicylates, so it can be a hidden trigger if you react to aspirin or salicylate-rich foods
- Fermentation raises free glutamate, another reason a small forkful can feel like a lot
