For a small percentage of people, cocoa can be a migraine trigger. It’s not the cocoa itself, but the tyramine and phenylethylamine it contains—neuroactive compounds that can dilate blood vessels in some sensitive individuals. If you’ve noticed that a chocolate binge is followed by a throbbing headache, you’re not imagining it. Keep a food diary for a week and see if your cocoa consumption lines up with those pain days. Your brain might be trying to tell you something.
Oxalates and Kidney Stones
Here’s a deeper cut: cocoa powder is very high in oxalates, which can bind with calcium in your body to form kidney stones. Two tablespoons of raw cocoa have about 150-200 milligrams of oxalates, and the daily limit for people prone to stones is around 100. If you’ve ever had a kidney stone—and trust me, you’d remember—you might want to limit your cocoa intake or pair it with calcium-rich foods like milk or yogurt. The calcium helps bind oxalates in the gut rather than the kidneys.
