1. Two Bananas – makes a big dent in your daily RDI of potassium
Potassium plays several vitals roles in our bodies. It is used by every cell you have to generate the electrical charge needed for life processes. Potassium is also involved in regulating blood pressure, steadying your heart rate, and triggering insulin release. In partnership with sodium, potassium also works to control fluid levels in your body.
Despite its importance, many of us don’t get enough potassium on a daily basis. The RDA for potassium in healthy adults is in the range of 3,500-4,700mg per day, your actual needs being determined by lifestyle and other factors. Two average-sized bananas will net you about 900 mg of potassium, which is a solid start but does not get you all the way there. Additional sources of potassium include potatoes (white and sweet), watermelon, spinach, beets, white beans, and tomato sauce.
