Foods that Contain Potassium

About Potassium

Potassium is a mineral and an electrolyte. It aids in cell, organ and tissue function. As an electrolyte, it works with other electrolytes in the body to conduct electricity. Potassium benefits heart function, the contractions of muscles, and aids in digestive function. Research has been linking potassium to certain health benefits. They include bone health and reducing the risk of stroke.

The following are foods that contain potassium. These foods can easily be incorporated into many different eating plans to help add more potassium to the daily diet.

Spinach

Spinach is a potassium-rich food that can easily be consumed raw or cooked. It can be added to salads, casseroles, soups and sandwiches with ease. It can also be eaten independently, sometimes seasoned with lemon juice, pepper, butter or lemon pepper.

One cup of boiled spinach contains almost 35 percent of the RDA (recommended daily allowance) for potassium. It also has significant amounts of nutrients such as vitamin K, vitamin A, folate, manganese, magnesium, vitamin C, vitamin B2 (riboflavin), calcium and iron.

Crimini Mushrooms

Available year-round, five ounces of raw crimini mushrooms contain almost 20 percent of the recommended daily allowance RDA for potassium. These mushrooms are also high in RDA values for selenium, vitamin B2, vitamin B3 (niacin), copper, tryptophan and vitamin B5 (pantothenic acid).

Kale

A cruciferous vegetable, kale is best cooked by steaming it. Cooking it in this method helps protect the properties in kale that help reduce cholesterol levels.

The RDA for one cup of boiled Brussels sprouts is approximately 15 percent. Brussels sprouts are also high in vitamin C, vitamin K, folate and vitamin A. Other nutrients that may be found in Brussels sprouts include manganese, dietary fiber, tryptophan, vitamin B6, vitamin B1 (thiamin), iron, phosphorus, omega-3 fatty acids, protein, vitamin E, magnesium, vitamin B2, vitamin E, calcium and copper.

Broccoli
