Does Blending Fruit Destroy the Fiber?

Does blending fruit destroy the fiber? Scott Tindal is joined by Fuelin dietitian Megan Foley to take apart two claims doing the rounds online, starting with the viral warning against blending bananas with blueberries, which came from a trial of eight men that never once put the two in the same glass.
