Not Enough Potassium
Your kidneys need a balance of sodium and potassium to keep the right amount of fluid in your blood. So even if you're eating a low-salt diet, you could still have higher blood pressure if you're not also eating enough fruits, veggies, beans, low-fat dairy, or fish. While you may think of bananas as the go-to source, broccoli, water chestnuts, spinach, and other leafy greens are better to get potassium if you're watching your weight.
