Low-Histamine Diet and Supplements – What to Eat and Avoid with Histamine Intolerance
Histamine intolerance is becoming increasingly recognized, especially among people struggling with diffuse symptoms such as headaches, digestive issues, skin reactions, or fatigue. For many, the solution lies in adjusting the diet and supporting the body with the right supplements. Here we go through what to eat – and what to avoid – as well as how to optimize gut health and benefit from a low-histamine diet.
Which Foods Contain the Most Histamine – and Which Are Safe?
Histamine occurs naturally in many foods, but some contain significantly more than others.
Foods high in histamine (avoid or minimize):
Aged cheeses
Cured meats and smoked meat
Wine, beer, and other alcohol
Fermented foods (sauerkraut, kombucha, soy sauce, miso)
Fish and seafood that are not completely fresh
Tomato, eggplant, and spinach
Foods often safer for histamine intolerance:
Fresh meat and fresh fish (chilled quickly after slaughter/catch)
Eggs
Gluten-free grains (rice, quinoa, oats)
Cooked vegetables such as zucchini, cucumber, cauliflower, carrot
Pears, apples, blueberries, and other low-histamine fruits
Olive oil and coconut oil
How Fermented Foods, Alcohol, and Aged Products Affect Histamine Levels
Fermentation, storage, and ripening processes increase histamine content in foods. That’s why otherwise “healthy” foods like sauerkraut, kefir, and wine can be problematic for those with histamine intolerance. Alcohol also adds a double burden – it often contains histamine and inhibits the body’s ability to break it down.
Supplements That May Help with Histamine Intolerance
In addition to diet, certain nutrients and supplements can provide support:
DAO enzyme – helps the body break down histamine in the gut.
Vitamin C – acts as a natural antihistamine and can reduce histamine release.
Quercetin – a plant flavonoid that stabilizes mast cells and reduces histamine release.
Magnesium – supports normal nerve and muscle function and reduces stress load that can trigger histamine reactions.
Vitamin B6 – needed for DAO production and thus effective histamine breakdown.
The Connection Between Gut Health and Histamine Intolerance
An imbalanced gut flora or leaky gut can worsen histamine intolerance. Some bacterial strains produce histamine, while others help break it down. By strengthening your microbiome, you can reduce symptoms:
Choose probiotics with low-histamine strains (e.g., Lactobacillus rhamnosus GG and Bifidobacterium longum).
Avoid probiotics that increase histamine (e.g., certain strains of Lactobacillus casei).
Eat prebiotic foods (cooked and cooled potatoes, green banana, Jerusalem artichoke) to support a balanced gut flora.

A low-histamine diet can be an effective tool for those struggling with histamine intolerance. By avoiding histamine-rich foods, choosing fresh alternatives, supporting the body with DAO and other nutrients, and strengthening gut health, you can significantly reduce symptoms.
Remember: Everyone reacts differently to histamine, so keeping a food diary and adjusting your diet to your own body is highly recommended.
