Potassium and Your Blood Pressure

Potassium and blood pressure

If you have high blood pressure (hypertension) you’ll be happy to hear that there are several lifestyle changes you can make to help reduce and control your blood pressure.

In terms of changing what you eat and drink, the main focus is on reducing sodium (salt). But, did you know that potassium plays an important role in reducing blood pressure too? Potassium is an important nutrient that helps the cells in your body to function normally. Nerves and muscles can’t work without it and it helps control blood pressure.

Like two sides of a coin, sodium tends to raise blood pressure, while potassium tends to lower it. On average, Canadians eat too much sodium (more than double the recommended amount) and not enough potassium. High sodium levels are often the result of eating too many highly processed foods that have added salt or other high sodium ingredients like soup base, processed meats and soy sauce.

How to Eat More Potassium-Rich Foods

Start by filling half your plate with fruits and veggies. While leafy greens, squash and root vegetables are great sources of potassium, you also can’t go wrong by simply eating more of the vegetables and fruit you enjoy.

A few tips:

  • Double up on veggies the next time you make sandwiches, soups or stir-fries.
  • Get into the habit of having salad or a plate of cut veggies and dip with your supper.
  • Try making fruit-based desserts like baked apples with nuts and raisins or pumpkin custard, instead of having cakes, squares or ice cream.

Add these Potassium-Rich Foods to Your Meals

  • Vegetables like sweet potatoes, tomato paste and chard
  • Fruit like bananas, apricots and kiwi
  • Grain products like wheat and oat bran, whole grain pasta or oats
  • Milk products like plain milk and yogurt
  • Soy products like fortified soy beverage, roasted soy beans or textured soy protein
  • Bean and lentils like refried beans, baked beans or split red lentils
  • Nuts and seeds like sunflower seeds, peanut butter and almonds
  • Fish and lean meat like salmon, chicken thighs or pork loin

Eating more potassium-rich foods is just one part of healthy eating that can help reduce your blood pressure. For a more detailed eating plan check out the DASH Diet (Dietary Approaches to Stop Hypertension). It’s a well balanced approach that aligns with Canada’s Food Guide and has been proven to reduce blood pressure.

Speak with your doctor or dietitian before deciding to eat more potassium-rich foods. If your kidneys are not working properly, or you are taking certain medications, potassium can build up in your blood and cause health problems.
