Top 10 Foods Highest in Potassium

Potassium is an essential nutrient used to maintain fluid and electrolyte balance in the body. It also plays a critical role in the transmission of electrical impulses in the heart.

A deficiency in potassium causes fatigue, irritability, and hypertension (high blood pressure). (2) Unless you are on dialysis or have a special condition, an overdose of potassium from natural sources is nearly impossible. Signs of high potassium blood levels include weakness, paralysis, and heart palpitations. (2)

High potassium foods include leafy green vegetables, fish, white beans, avocados, potatoes, acorn squash, milk, mushrooms, bananas, and cooked tomatoes. The current daily value (DV) for potassium is 4700 milligrams (mg), recently raised from 3500mg by the FDA. (1)

Below is a list of high potassium foods ranked by common serving sizes, for more see the lists of high potassium foods by nutrient density, more potassium rich foods, fruits high in potassium, and vegetables high in potassium.

How much potassium do you need each day?

The percent daily value (%DV) and the recommended daily intake (RDI) for adults is 4700mg per day. (2)

Here are the breakdowns of the RDIs by age group:

  • Age 14+: 4700mg
  • 9-13 years old: 4500mg
  • 4-8 years old: 3800mg
  • 1-3 years old: 3000mg

Who is at Risk for Potassium Deficiency?

  • Alcoholics (3)
  • People with a magnesium deficiency - Low magnesium levels increase potassium excretion and further increase the risk of muscle cramps and cardiac arrhythmias. (2)
  • People taking Diuretics - Diuretics like thiazide, which are used to regulate high blood pressure, can increase the amount of potassium excreted in urine. Certain potassium sparing diuretics have the opposite effect and can cause the body to retain too much potassium. If you are taking diuretics talk to your health care provider for more information. (2)

Health Benefits of Potassium

  • Alleviation of High Blood Pressure (Hypertension) and Reduced Risk of Stroke - A diet low in potassium and high in sodium can result in high blood pressure over time. High blood pressure causes damage to the arteries and veins, which can lead to strokes and heart disease. Eating foods high in potassium while limiting foods high in sodium can help reduce blood pressure over time. (2,3)
  • Reduced Risk of Kidney Stones - Adequate potassium levels are necessary for calcium reabsorption from the kidneys. Diets low in potassium lead to higher levels of calcium in the kidney which increase the risk of kidney stones. (2,3)
  • Osteoporosis Protection - Several studies have found a relationship between increased bone density and increased intake of dietary potassium. These studies were true even for post-menopausal women and older men. (2,3)
  • Reduced Risk of Type II Diabetes - Potassium is necessary for insulin secretion, and numerous studies have found a correlation between low potassium levels and higher levels of fasting blood glucose and insulin resistance. (2,3)

What foods are low in potassium?

Foods low in potassium include most refined fats and oils, grains like cornmeal, white rice, and white pasta, some cheeses like soft goat cheese, blueberries, leeks, and napa cabbage. Boiling vegetables in water and discarding the water they are cooked in can help reduce their potassium and electrolyte content. For more, see the article on low potassium foods, and low potassium vegetables.

About Nutrient Targets

Setting targets can provide a guide to healthy eating.

Some of the most popular targets include:
  • Daily Value (%DV) - The daily value (%DV) is a general guideline for consumption that will prevent deficiency of a particular nutrient in most people. The %DV refers to the percentage of an amount that's found in a single serving of a food. It also accounts for absorption factors. It is set by the U.S. FDA.
  • Recommended Dietary Allowance (%RDA) - The RDA sets an average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97.5%) healthy individuals. It's more specific than the daily value, and varies by age and gender. The RDA is set by the US National Institutes of Health.
  • Reference Dietary Intake (%RDI) -The reference dietary intake is similar to the recommended daily allowance, but is specific to age and gender. The RDI for amino acids is set by the U.N. World Health Organization.
  • Adequate Intake (%AI) - This value is primarily used in reference to omega-3 and omega-6 fats. The Adequate Intake is set by the U.S. Institute of Medicine. Because there is less evidence to determine the ideal targets for consumption of these nutrients, the specific amount is considered to be less reliable. Using the term Adequate Intake, rather than one of the other terms, helps to emphasize that the ideal intake of that particular nutrient has not yet been scientifically determined.

See the Guide to Recommended Daily Intakes for more information.
