Is Asparagus High or Low in Potassium?

Unlike many vegetables, asparagus is low in potassium. It's also highly nutritious, so it is an excellent dietary addition for those with kidney issues or potassium sensitivity.

How Much Potassium Does Asparagus Have?

One cup of boiled asparagus contains around 200 mg of potassium; foods containing this amount or less are considered low potassium. So, most people following a low-potassium diet should be able to add a little asparagus without experiencing any ill effects.

  • Are Nuts High in Potassium?

Canned asparagus, however, contains a little more, with a serving containing around 400 mg of potassium.

Canned asparagus also contains more sodium, as the canning process adds salt and leaches other minerals.

Is Asparagus Healthy?

Asparagus is one of the most nutritious vegetables. It's rich in folic acid, which supports the formation of healthy red blood cells and is a particularly important nutrient during pregnancy.

It's also low in calories, and just one cup contains 4 g of protein and 4.4 grams of fiber.

Can You Get Too Much Potassium from Asparagus?

It would be almost impossible to get too much potassium purely by eating asparagus. However, people on a low-potassium diet should check the potassium content of every food in their meals to come to a total.

If you love asparagus but are worried about its potassium content, soak it in cold water for two hours and then cook it with plenty of water; this leaches some of the potassium out.
