What to know about peanut butter
Peanut butter's biggest hidden trigger is nickel: peanuts are legumes and rank high on the nickel scale, which makes peanut butter a frequent flare food for people with systemic nickel allergy, showing up as eczema, itching or gut upset. On top of that it carries moderate oxalate, a mild histamine-liberating effect and some lectins, so it stacks several small loads at once. None of this is the same as a true peanut allergy, which is a separate and potentially serious IgE reaction: if you have that, the nickel grading is irrelevant and you must avoid peanuts entirely.
Watch for
- High in nickel, a common trigger for systemic nickel allergy (eczema, itching, digestive upset) because peanuts are legumes
- Moderate oxalate, worth noting if you are prone to kidney stones or follow a low-oxalate diet
- Mild histamine liberator and moderate in lectins, so it adds to the overall load even though neither is severe on its own
- Separate from all of this, a true IgE peanut allergy is an anaphylaxis risk and means strict avoidance, not moderation
