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)

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.
