Blueberries are low in calories, high in fiber and help reduce the risk of chronic disease. Studies show that blueberries can improve heart and brain health, as well. Cashews have a sweet, buttery taste and are an excellent source of several vitamins, minerals and antioxidants. These healthy and delicious ingredients come together in this smoothie with the addition of mint leaves and a squeeze of lime juice. We’re on the cusp of blueberry season in Massachusetts, but feel free to substitute frozen blueberries for fresh. A spoonful of your favorite yogurt or protein powder could be a fun addition to this refreshing beverage.
