Rumor: Vinegar soaking black beans can lower blood pressure.
Truth: It is not feasible to lower blood pressure by soaking black beans in vinegar.
Vinegar soaking black beans is only a relatively healthy dish, but it is impossible to lower blood pressure by relying solely on one dish or ingredients. If you don’t like jealous soaking black beans, you can not eat them at all.
If you want to help control your blood pressure by diet, you should maintain a healthy diet as a whole, rather than relying on a certain dish or a certain dish.
