The women of Okinawa, Japan (who also happen to be the world's longest living ladies) enjoy a purple sweet potato they call imo every day for breakfast, lunch and dinner. Rich in beta-carotene and boasting 150% more antioxidants than blueberries, sweet potatoes are also super high in heart-healthy vitamin A. They’re also packed with vitamin C to keep your immune system strong, especially during cold and flu season. If you can't find imo specifically, our orange sweet potatoes pack a similarly healthful wallop.
How to use them: Substitute sweet potatoes for regular potatoes. Bake them or mash them, but avoid dousing them in sugar or syrups to keep their rich nutritional value intact. You can also microwave or steam them with as little water as possible to retain the maximum amount of nutrients. Try an Oz-approved sweet-potato recipe tonight!
