Here are 5 foods that have more potassium than bananas, plus a list of 20 potassium containing foods to easily add to your meals.

When you think of potassium-rich foods, what’s the first thing that comes to mind? My guess is that it’s bananas. It’s no lie that they pack in potassium, but did you know there are a lot of foods that are actually higher in potassium than a banana? Many people even think that they need to take an electrolyte supplement to stay hydrated and reach their potassium needs, but a balanced diet can easily do the trick! Here’s a list of potassium-rich foods to help you deliciously diversify your intake of this important mineral.

What is Potassium?

First off, what exactly is potassium? It’s an essential mineral, meaning we need to take in sources of potassium through the diet to meet the body’s needs. Potassium is crucial for a number of functions within the body including:

  • blood pressure regulation
  • muscle contractions
  • digestion
  • pH balance
  • nerve transmission
  • kidney function

The Daily Value (DV) for potassium for healthy adults is 4,700mg for adults, but this number can vary for individuals with certain conditions such as diabetes, kidney disease, or osteoporosis.

How Much Potassium Is in a Banana?

For comparison purposes to these other fruits and vegetables, it’s important to know how much potassium is in a banana. One medium banana contains 422mg of potassium. 

What Food has More Potassium than Bananas?

While some people fall short of their potassium requirement, regularly incorporating foods from this list of potassium-rich foods will ensure you are meeting your goals. These 5 foods are great sources of potassium!

  1. Potatoes
  2. Watermelon
  3. Spinach
  4. Beets
  5. Avocados

1. Potassium in Potatoes

One medium potato delivers 610 mg of potassium, or roughly 17% of the daily value (DV). That’s about 40% more potassium than you’ll find in a banana, which only contains 422 mg, or 9% DV.

In addition to potassium, 1 medium potato provides 5 grams of fiber, 4 grams of protein, vitamin C and magnesium. This Warm Potato, Leek, and Lentil Salad with Citrus & Herbs is a delicious way to get in more potassium, and give the potato the recognition it deserves.

2. Potassium in Watermelon
