ADVICE

Make Avocado Your Go-To Potassium Food

Eat avocados as a primary potassium source instead of starchy fruits or tubers.
One avocado ≈700 mg potassium, zero starch and net carbs, plus healthy fats and magnesium that slow digestion and aid absorption.

INSIGHT

Wild Salmon Packs Exceptional Potassium

Wild salmon is an unusually high-potassium animal food with 970 mg in about half a fillet.
It provides potassium with zero carbs, plus magnesium and omega-3s, making it doubly beneficial for electrolyte balance.

ADVICE

Cook Greens To Preserve Potassium

Prefer sautéing or steaming leafy greens to preserve potassium rather than boiling them.
Swiss chard, beet greens, and cooked spinach provide very high potassium (up to 1,300 mg per cup) and low carbs when prepared this way.

Most people are told to eat bananas when looking for potassium-rich foods to add to their diet. If you want to boost your potassium intake, bananas, potatoes, plantains, beans, and sweet potatoes aren’t always the best options. Although these foods contain potassium, they also contain a significant amount of sugar.

One avocado contains 700 mg of potassium, zero starch, and zero net carbs. Avocados are also a potent source of healthy fats and magnesium.

Leafy greens such as Swiss chard and spinach are high in potassium but also high in oxalates. Consuming leafy greens with calcium can help reduce the effects of oxalates.
