Cocoa powder/Dark chocolate

 Who would have thought chocolate would be among the heart-healthy foods? However, it's worth noting that only chocolates with a high cocoa content are heart-friendly, as cocoa powder is rich in flavonoids, bioactive compounds with anti-inflammatory and antioxidant properties, and also helps release nitric oxide, responsible for vasodilation and consequent blood pressure reduction.

An interesting fact about cocoa is that although the fruit is also rich in potassium and flavonoids, approximately 70% of the cocoa is discarded in traditional production, leaving only the beans used. Cocoa also increases the production of serotonin, responsible for well-being, and is high in magnesium, a mineral that helps combat depression, insomnia, and anxiety.
