Is dark chocolate actually healthy?
In moderate amounts (20–30 g of ≥70% dark chocolate daily), yes — associated with better blood pressure, mood, and vascular function.
Cocoa flavanols improve how well the lining of your blood vessels relaxes and opens (endothelial function), modestly lower blood pressure, and may support cognition. Benefits require high cocoa content (≥70%) and modest portions; sugary milk chocolate does not qualify. The COSMOS trial (2022) suggested cocoa extract reduces cardiovascular death.
