Sensitivity notes
Why histamine food checker matters
Histamine is a compound naturally present in many foods, especially aged, fermented, or preserved items. In sensitive individuals, excess histamine can cause headaches, flushing, hives, digestive issues, and other symptoms. Your body normally breaks down histamine, but some people have reduced capacity to do so.
- Focus on fresh foods - histamine builds up as food ages
- Cook and eat meals fresh; avoid leftovers sitting more than 24 hours
- Be cautious with fermented foods, aged cheeses, and cured meats

Serving size, prep, and portion notes for macadamia nuts
Macadamias are the nut most often recommended as the safe one: they are low histamine and among the lowest-FODMAP nuts in a normal serve, which is why gut and histamine protocols reach for them first. The catch is salicylates. Macadamias are high in salicylates, so if you are salicylate sensitive or react to aspirin, the usual safe nut can still set you off. They are also a tree-nut allergen and very high in fat.
Watch for
High in salicylates, the one real catch on an otherwise gentle nut, and the reason it can trigger people who tolerate its FODMAP and histamine profile fine / Low FODMAP in a standard serve and low in histamine, which is exactly why it is the go-to safe nut for IBS and histamine intolerance / Moderate nickel, usually a minor issue but worth noting if you stack it with other nickel-rich foods / A tree-nut allergen and very high in fat, so large portions can also unsettle digestion
