Great news for dark chocolate fans. British scientists have found that cocoa lowers blood pressure and protects the heart.
If you cannot imagine your life without sweets, then choose dark chocolate as your favorite snack. The fact is that cocoa beans contain flavanols, which improve heart health by lowering blood pressure. They achieve this effect by making the walls of blood vessels more elastic. This makes it easier for the blood to circulate throughout the body.

But the much more popular milk chocolate is not suitable for this, because it has too high a sugar content, but the share of cocoa beans is only 25%. For comparison, in dark chocolate, this figure can reach 90%. Researchers at the University of Surrey found that people who supplemented with chocolate had lower blood pressure and stronger blood vessels within three hours.
Cough is better treated with chocolate
The tablets they ate contained as much flavanol as one would find in 500 grams of dark chocolate. Of course, it is not very reasonable to consume so many of these sweets, so you should be content with a smaller amount, or drink cocoa in its pure form. It is impossible to deny that cocoa has a positive effect on the cardiovascular system. In Russia, more than 40% of adults suffer from high blood pressure or hypertension, which increases the risk of heart attacks and strokes. (READ MORE)
