High Potassium Foods

Most fruits are high potassium foods. Some however are low in potassium or have small serving sizes and thus provide little potassium. In this table we have included those that have less than 100 mg in a serving of the food. There are some fruits that have between 100 mg and 200 mg in a serving and can be considered intermediate. If less than a full serving of these intermediate fruits is eaten, they can be consumed by someone on a low potassium diet. Generally the high potassium foods should be avoided for those on a restricted diet, although small amounts can be eaten, such as a slice of banana, for example.

Some Common Fruits

Some of the most common fruits are in the low potassium category because of serving size. These include apples, rose-apples, blueberries, grapes, pears and peaches. Also their juices or nectars are low in potassium. They also are low in sodium, which also should be restricted for those who need a low potassium diet.

The sauces and toppings, such as apple sauce or blueberry topping, should be limited to about the same weight as would be present in a serving of the whole fruit. The serving value for a juice or nectar is given in the table. This is generally equivalent to a glass or cup. Juice or nectar can provide an alternate way to get some of the nutrition present in the fruit.

The Table

The serving weight is grams, and the potassium and sodium entries are milligrams. The potassium and sodium values given are for 100 grams of food.

As usual, K is potassium, and Na is sodium.

Except for the amount of potassium per serving and the potassium sodium ratio (which we calculated), the source of data is: USDA National Nutrient Database Standard Reference – Release 22.
