Bananas are especially recommended because of their high potassium content. Especially for patients with high blood pressure, it is recommended to eat a banana every day, and some patients even boil banana peels to eat every day, which can lower their blood pressure partly, because foods with high potassium content have a little lowering effect on blood pressure.
