Last week, Bananas were the Prenovate community's most popular food. You've probably spent a lifetime hearing how healthy bananas are, but did you know that their sterling reputation is based on their high potassium content? If you have chronic kidney disease and your doctor has told you to limit your potassium, you might want to switch out bananas for Grapes* to satisfy your sweet tooth. Check the grades for your favorite food with Prenovate's Food-Grading Engine.

*Grapes also have a lower glycemic index than bananas, which could make them a better choice for someone who has CKD along with diabetes.*
