What foods have the lowest potassium levels?

The foods with the lowest potassium include fats, such as olive, sesame, canola and sunflower oil; rice noodles; spices, such as ginger, dill weed, mace and thyme; and vegetables, such as arugula and onions, according to the USDA. Low-potassium fruits include grapes, peppers and cranberries.

Eggs as well as some cheeses, such as Cheddar and Swiss, are low in potassium. Cereals and breads are often low in potassium as well. Pork is a low-potassium meat. Draining canned vegetables prior to use removes excess potassium. Soaking vegetables for two hours as well as peeling the skins can further reduce potassium content.
