Have you ever woken up in the middle of the night with an awful leg cramp or felt faint after a light workout? These may be signs that your body is missing an important mineral: potassium. The good news for those with low potassium levels is that you can find it in many of the foods at your local grocery store. Potassium-rich foods include bananas, dried fruit, leafy greens, chicken, salmon, almonds, and lentils.

What is potassium?

“Potassium is one of seven essential macrominerals humans need to support multiple body processes,” said Amy Lee, MD, and chief medical officer at Lindora Clinic in Southern California.

According to Dr. Lee, the roles of potassium in the body include:

Regulating fluid balance
Maintaining healthy nerve function
Regulating the contraction of muscles
Regulating heart contractions for normal blood pressure

“Potassium is really important for bone health since it helps reduce the amount of calcium lost through the urine,” added Megan Hilbert, a registered dietitian specializing in gut health nutrition at Top Nutrition Coaching.

How much potassium should people have each day?

According to the dietary guidelines from the American Heart Association, the recommended daily intake is around 3,400 milligrams (mg) of potassium for men and around 2,600 mg of potassium for women. This amount of potassium is only suggested for healthy people ages 19 to 50. For example, those with kidney disease can have too much potassium in their blood and should be more careful with their potassium intake.

Always speak with your healthcare provider before changing your diet to ensure it will not negatively affect any medical conditions you may have, such as heart disease, kidney problems, or hypertension.

Potassium-rich breakfast ideas

A breakfast smoothie

“Smoothies are such a great go-to if you’re looking to incorporate more potassium into your diet, because so many fruits and veggies are a great source of potassium,” said Hilber. “A strawberry banana smoothie with some avocado and spinach would be a great choice for a high potassium breakfast or even snack.”

Dr. Lee agreed, “I’d recommend a potassium-packed smoothie with banana, avocado, spinach and honey.” You can also add Greek yogurt and oranges for extra potassium, depending on your preferences.

Yogurt bowls

Add some bananas, almonds, and dried fruit on top of your yogurt for an extra boost of potassium.

Veggie omelet

Make a morning omelet and throw in your favorite potassium-rich veggies like spinach, tomatoes, and mushrooms.

Potassium-rich lunch ideas

Avocado toast

Put some mashed avocado on top of whole-grain toast and add tomatoes, smoked salmon, and any other toppings you enjoy for a hearty and healthy lunch or brunch.

A hearty salad

“Salads are also a great choice since they incorporate lots of fresh produce as well,” Hilber suggests. “A spinach-based salad with sweet potato cubes, avocado, dried apricots, and some pomegranate seeds would contain lots of potassium-rich foods. “

A chicken and veggie wrap

Add some grilled chicken, spinach, tomatoes, carrots, and avocado to a wrap with your favorite veggies and dressing for a lunch packed with potassium.

Lentil curry

“Curry with lots of lentils or beans, fresh vegetables like kale, squash, bell peppers, broccoli, and served with a side of brown rice could be a great choice for a high potassium dinner,” Hilber says.
