Raspberry Basil Healthy Smoothie Recipe by Green Blender: This sweet and bright mixture contains heart-healthy walnuts, lycopene-rich tomatoes, and superfood goji berries. The immune system-boosting goji berries (also known as wolf berries!) come from China, Mongolia, and the Himalayas. They contain an antioxidant called zeaxanthin which can help in protecting the eyes from ultraviolet rays. Goji berries contain vitamins A and C as well as iron to help with cell renewal.
