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
