Dried mulberries are a great source of protein, vitamin C and K, fiber, and iron. Best of all, they’re available in health food stores everywhere! Enjoy them as a great snack all by themselves or add them to your favorite trail mix. If you live in a warm climate and are lucky enough to have mulberry trees nearby, you can enjoy the fruit fresh off the tree. Not as tasty as the fruit, even the leaves contain protein, fiber, and nutrients.
