If you live in North America, you probably donโ€™t get enough potassium. An often overlooked mineral, potassium is an unsung hero, critical for maintaining the bodyโ€™s fluid balance, muscle and nerve function. Potassium controls electrical signaling in the heart and plays an important role in synthesizing proteins and building muscle. Research shows that getting enough potassium relaxes blood vessels, helping to prevent and treat high blood pressure.

Women who are breastfeeding need a little bit more - 5100 mg per day.  For perspective, the average American takes in only 1700 mg daily, and Canadians arenโ€™t far behind.

High dose potassium supplements can disrupt heart rhythms so itโ€™s best to get your potassium from food. Superstars include white beans like cannellini or navy beans, which provide almost 600 mg per half-cup. Potassium-rich vegetables like Swiss chard (480 mg), spinach (400 mg), and beet greens (650 mg) pack a hefty potassium punch per half-cup portion, cooked. Plain yogurt is yet another great option, clocking in at 580 mg per half-cup serving.  Fruits like banana (420 mg) and dried apricots (380 mg per ยผ cup) are also good choices.
