According to Megan Byrd, registered dietitian (RDN) and founder of The Oregon Dietitian, "banana is very high in potassium, fiber, and antioxidants, which can reduce risk of risk of developing disease later in life. Bananas can also offer some digestive support due to the fiber and prebiotics founds in the fruit. Pineapple is extremely high in antioxidants as well as vitamin C, which helps iron absorption and provides immune support, too! Although bananas and pineapple provide different health benefits, when combined, they create a true superfood smoothie!"
