What to know about hazelnut
Hazelnuts are one of the highest-nickel tree nuts, which is the main reason they trigger people even when other snacks feel fine. They are moderate on FODMAPs (from galacto-oligosaccharides) and only mildly histamine-raising, so a small handful is usually tolerated, but chocolate hazelnut spreads, gianduja and praline concentrate them and are a common flare culprit. As a major tree-nut allergen they also hide inside a lot of baked goods.
Watch for
- High in nickel, the strongest trigger here, which matters if you have systemic nickel allergy: chocolate-hazelnut spreads and pralines pack a lot of hazelnut into one serving
- Moderate FODMAP load from galacto-oligosaccharides, so a few nuts are fine for most but a jar of spread or a bag of them can bloat a sensitive gut
- Mildly histamine-active, and roasting or long storage tends to push that higher
- A major tree-nut allergen that hides in praline, gianduja, nut flours and many desserts
