Many people want to know why potassium lowers blood pressure. Usually, they focus on reducing the amount of salt they eat, but this is not the only way to make your heart healthier.
It is important to increase your potassium intake, as it will help your body’s systems function better. Your kidneys require a balance of sodium and potassium, which work together to move sodium out of your cells and into your urine.
Several studies have demonstrated that higher potassium intake decreases systolic and diastolic blood pressure. However, there are several limitations to these studies.
For example, the researchers found no effect with an increase in potassium intake during the first week of a study, and no difference was seen in the second or third week of the study. The researchers concluded that high-potassium diets may not be enough to control hypertension.
The most important question is how much potassium a person should consume. Some studies indicate that potassium can lower blood pressure by about 5 mm Hg, and that higher intakes are associated with lower hypertension.
But other studies have shown that the effects of high-potassium diets were more significant. And, although these studies have been conducted on human subjects, they have not been replicated in animal models. Therefore, more research is necessary in human studies.
