How does potassium lower blood pressure?

potassiumWhen it comes to healthy blood pressure, you need to balance your intake of sodium and potassium. High blood pressure, or hypertension, is when the pressure of blood flow pushes against the veins. High blood pressure can contribute to other major heart events and even stroke. High blood pressure can be symptomless, and if not monitored, it will only reveal itself through a major heart event. This is why it’s important to monitor your blood pressure and take preventative measures to keep it in a normal range.

One way a person can control their blood pressure is through potassium. Potassium is an essential mineral that our bodies require. Research suggests that by taking potassium, you can better manage your blood pressure.

Recommended potassium intake

Potassium is naturally found in the body as well as in many of the foods we eat. Therefore, getting an ample supply of it is quite easy. Potassium is used in the body in many ways, but one function, in particular, is to support heart health.

Because the typical American diet is high in sodium, it can lead to potassium deficiencies. High sodium has been linked to high blood pressure as well. Therefore, to combat the effects of sodium, it’s essential to get adequate amounts of potassium.

The current recommendation for potassium is 4,700 mg a day for those over the age of 14.
As mentioned, potassium can be found in many health foods including leafy greens, fruits, grain products, dairy, and meat.

Potassium-sodium balance effect on blood pressure levels

The American Heart Association (AHA) suggests eating foods that contain potassium is a good way to boost potassium levels and better manage blood pressure. Potassium can flush out excess salt from our diet. Salt has been linked to increased blood pressure. Potassium works to weed out salt through a process that occurs in the kidneys.

The kidneys control fluid within the body. Excess fluid gets pulled into the bladder where urine is formed. Both sodium and potassium are used during this process to bring the fluid into the bladder. A diet high in sodium disrupts the balance between salt and potassium, making this pulling of fluid much more difficult. By increasing potassium intake, balance can be restored again, leading to healthier kidneys and improved blood pressure.
