Overview
About dark chocolate
Dark chocolate has real upsides, since its cocoa flavanols make it anti-inflammatory, but that same cocoa is high in histamine, a histamine liberator, high in nickel and high in oxalate, with a moderate dose of caffeine.
That is why a couple of squares can bring on a migraine, flushing or a nickel-type skin flare in sensitive people even though it is one of the better-for-you sweets.

FAQ
Common questions about dark chocolate
Why does dark chocolate trigger migraines?
It hits two migraine levers at once: it is high in histamine and a histamine liberator, and it also carries caffeine. For people whose headaches are tied to histamine or vasoactive foods, even a small amount of dark chocolate can be enough.
Is dark chocolate high in nickel?
Yes. Cocoa is one of the highest-nickel foods, so dark chocolate is a common flare food in systemic nickel allergy syndrome. The higher the cocoa percentage, the more nickel and oxalate it tends to carry.
Is dark chocolate better than milk chocolate for food triggers?
It depends on your trigger. Dark chocolate has far less dairy and is anti-inflammatory rather than pro-inflammatory, so it is better for a dairy or inflammation issue. But it is higher in oxalate, caffeine and cocoa-driven histamine, so milk chocolate can actually feel milder for a histamine or oxalate problem.
