Banana Cocoa Smoothie

This sweet breakfast treat is rich in potassium (from the bananas), calcium (from the soymilk), and magnesium (from the cocoa), three minerals that strengthen brain function and reduce anxiety and fatigue. In addition, the isoflavones in the soymilk may help prevent cancer and heart disease. Prefreeze peeled bananas in resealable plastic bags, and break into chunks before blending into smoothies that are thick and rich, not watery.
