Potassium is a mineral that is found in most fruits and vegetables. It is also found in some other foods. You may have been told to eat foods with more potassium, but it is sometimes hard to get enough. Adults need about 4,700 mg of potassium daily. Our need for potassium is even higher with certain medicines (such as diuretics) and with higher intake of salt (sodium chloride).

Milk and milk products have high amounts of potassium (370-412 mg per serving). This includes foods like yogurt, milk-based puddings and custards. We suggest low fat dairy choices.

Whole fruits and vegetables are the best way to add large amounts of potassium to your diet. They are usually lower calorie than other foods and provide antioxidants and other nutrients that we need in our diets.

Whole grain and bran breads and cereals contain some potassium, about 140 mg per serving, but are not very “high potassium” foods.

Meats, fish, poultry, peanuts, peanut butter, and eggs are moderate to high sources of potassium. These foods are also good sources of protein, which is needed for normal body function. But unlike fruits and vegetables, these foods cannot usually be consumed in large quantities. A registered dietitian can help you determine your protein needs.
