The Link Between Potassium and Blood Pressure

Dietary potassium is crucial to controlling your blood pressure levels. The presence of excess sodium in your body can raise your blood pressure. Increasing your potassium intake can help you eliminate more sodium through urine, which helps lower your blood pressure levels.

If you have high blood pressure, the American Heart Association (AHA) recommends consuming about 4,700 mg or 4.7 grams of potassium every day.

Foods Rich in Potassium That You Should Add to Your Diet

This refreshing summer fruit has about 112 mg of potassium in a 100-gram serving. Having 2 cups of watermelon (300 grams) can give you 7% of the daily recommended dietary allowance (RDA). Watermelon has just over 90% of water content and is low in carbohydrates. It is also high in vitamin A and magnesium content.

  • Banana

Banana is a fruit that is well-known for its potassium content. A medium-sized banana (about 100 grams) has around 358 mg or 7.6% of the daily RDA of potassium.

With 215 mg or 4.6% RDA of potassium per 100 milliliters, coconut water is a great alternative for sports drinks after a workout as it is rich in electrolytes. Along with being heart-healthy, coconut water is also diabetes-friendly.

Orange juice, grapefruit juice and lemon juice have about 200 mg, 162 mg and 103 mg of potassium per 100 grams respectively, i.e. they are fruits high in potassium. Frozen citrus juice concentrates usually contain 3x more potassium than their fresh variants.

Other Health Benefits of Potassium Rich Food

  • Protects Against Bone Loss

Potassium helps keep your bones healthy by preventing osteoporosis (brittle and weak bones). It preserves and improves bone density by preventing the loss of calcium from your bones.

  • Prevents the Formation of Kidney Stones

Potassium salts like potassium citrate can help lower the risk of kidney stones by reducing the amount of calcium in your urine and blood. Potassium citrate encourages the reabsorption of calcium by your kidney and protects against bone resorption (the breakdown of bone tissue which releases calcium into your blood and urine).

  • Helps Ease Muscle Cramps

Potassium plays a vital role in nerve and muscle function. One of the symptoms of low blood potassium levels is painful muscle contractions and cramps. Potassium transmits signals between your brain and muscles, which helps control the contraction and relaxation of your muscles. When the potassium levels in your blood are too low, your brain is unable to send these signals, which can lead to prolonged muscle contractions and cramping. 

  • Maintains Fluid Balance in Your Body

Potassium is an electrolyte that helps regulate the amount of water in your body and the concentration of other electrolytes like sodium in your blood. It can help eliminate excess sodium present in your body through urine, which prevents fluid retention or oedema.
