Most dairy products are among the high potassium foods. They are part of the DASH medical study diet that has been shown to reduce blood pressure, reduce osteoporosis and reduce kidney stone formation.
For the most part, 8 fluid oz of liquid milk or 8 oz of yogurt will provide approximately 400 mg of potassium. If it is fortified with protein, it will provide a bit more potassium. The dried or powdered milk will have a much higher potassium content and a higher content of potassium in the liquid milk can be obtained if the powder is not diluted as much as usually recommended.
Of course, potassium content is not the only consideration when determining whether to include a particular food in our diet. Notice that butter, cheese and ice cream are missing from the table. Butter and cheese are loaded with sodium and have little potassium. Many ice creams have a favorable potassium to sodium ratio, but only a moderate amount of potassium in the usual serving. We'll discuss these foods and some of the other nutritional factors further in the next post.
The weights for the potassium and sodium 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 potassium to sodium ratio (which we calculated), the source of data is: USDA National Nutrient Database Standard Reference – Release 22.
