Island Green Smoothie – Recipe of the Week

By: Stacy Kennedy, MPH, RD, CSO, LDN; Reboot Nutritionist

Even if it’s not warm and sunny where you are, this tart tropical treat is a refreshing breath of fresh air. This delicious smoothie is packed with important plant based nutrients like potassium and fiber.  A plant-based diet that includes potassium rich foods has been shown to help reduce blood pressure and replenish necessary electrolytes that can be lost through sweat on a hot day or with exercise.

Look for a ripe mango for a sweeter flavor.  Ripe banana and avocado will also lend better flavor, texture and nutrients to your smoothie.
