Serving size, prep, and portion notes for 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.
Watch for
High in histamine and a histamine liberator, a well-known migraine and flushing trigger / High in nickel, cocoa is one of the classic foods that flares systemic nickel allergy / High in oxalate, worth portioning on a kidney-stone diet / Contains caffeine, less than coffee but enough to matter for caffeine-sensitive people
