How does dark chocolate lower blood pressure

Dark chocolate and high blood pressure

Good news for chocolate lovers: dark chocolate is said to lower blood pressure.
One often reads about the positive effects of dark chocolate. Portuguese researchers have now substantiated this in a small study on 30 healthy participants between the ages of 18 and 27 years.

The subjects were divided into two groups. Both groups received 20 grams of chocolate daily over a period of 30 days: one group with a cocoa content of around 55 percent and the other group with a cocoa content of around 90 percent. Both groups showed positive effects on the vascular system. However, the group that ate the chocolate with the higher cocoa content achieved more pronounced results. The vascular tension decreased more clearly here. This also meant that the blood pressure values ​​were lower - especially the systolic pressure. There was also an improved interaction between the left ventricle and the large body artery, the aorta.
Structural changes in the heart itself, however, could not be detected. On the one hand, this may be due to the short duration of the study, but on the other hand, the participants in the study were all young and healthy.

In previous studies, too, the positive effects of dark chocolate were often reported - especially the flavonoids it contains.

However, hardly any significant reductions in blood pressure were observed in test persons with high blood pressure, which could safely be attributed to the consumption of chocolate.

Therefore, no explicit recommendation for the consumption of chocolate can be given. The potential positive effects are countered by the known negative consequences of increased consumption. Chocolate is very rich in energy and, if consumed excessively, makes it easier to get overweight. Teeth are also damaged by the sugar it contains.

In conclusion, it can be said that it is better to give in to the chocolate in the form of a dark chocolate with a high cocoa content instead of one of the varieties with little cocoa and a lot of sugar. Experience has shown that dark chocolate does not have to be the whole bar to satisfy the Schoko-Jieper. Usually a few bits of the dark pleasure are enough.
