2. Blueberries
You also may want to incorporate blueberries into your breakfast menu if you’re trying to eat a low potassium diet. That’s because blueberries have just 60 mg of potassium in one half a cup serving. That means that you can add blueberries to all kinds of other foods that are low in potassium and get the flavor from them without having to go over your potassium limits set by your doctor.
Cereal is a terrific breakfast food for those who are trying to stick to a low potassium diet, as long as you choose the right cereal. But the good news is, you can add some flavor to that low potassium cereal by adding ½ a cup of blueberries to it and you will still be barely over the 100 mg of potassium mark – particularly if you use the cereals that are suggested here.
