### Cocoa and Dark Chocolate
Cocoa flavanols may support endothelial function, but this is not a reason to consume large amounts of sugary chocolate.

Oily fish provides omega-3 fatty acids, which are associated with cardiovascular benefits.

It can be part of a healthy diet, but there is no need to drink a specific number of cups to “open” blood vessels.
Unsweetened green tea is simply one reasonable beverage option.
