Re:Chocolate can precipitate migraine so cardiometabolic benefit is doubtful

Migraines are caused (in many if not all) cases by the dilation of blood vessels. Many anti-migraine drugs cause the narrowing of said vessels (and can cause cardiac associated problems).

Therefore Chocolate and wine - which in the case of wine (red) is also known to dilate blood vessels, will cause migraine, but can be beneficial for certain cardiovascular symptoms. Therefore possibly chocolate can act like that as well.

I don't think, in fact, we have enough data and studies to draw final conclusions for either outcomes.
