Winter squashes such as acorn squash and butternut squash are high in potassium, a mineral your body needs to support cardiovascular, bone, and kidney health. The RealAge Optimum dose of this mineral is 3,000 milligrams per day. Add cubed or mashed squash to soups, stews, casseroles, and stir-frys for extra flavor and nutrition.

One cup of cubed squash contains almost 900 milligrams of potassium. Winter squash varieties include acorn, spaghetti, butternut, turnip, hubbard, banana, and carnival. These potassium-rich gourds can be baked, boiled, or steamed until the flesh is tender. Serve up squash as a side dish by pureeing butternut squash with a bit of olive oil, lime juice, and nutmeg. Or, serve it up as the main course by making a savory soup out of butternut squash, carrots, apples, sweet potatoes, olive oil, chives, and spices. Other good sources of potassium include dried peaches and apricots, potatoes, bananas, watermelon, tomato paste, and yogurt.
