I know this is a subject that has probably been fiercely debated, but I had little luck finding what I was looking for with the search tool. I apologize ahead of time if it has been covered ad nauseum.
I make a post-workout shake containing one banana, one boiled red potato, and 30g dextrose (to complement 45g whey protein), all blended together as a liquid in the blender. I know that Berardi and others recommend liquid nourishment and not whole foods post-workout. Does this apply to my shake -- despite being completely blended, is it considered "whole food" and do the carbs in it not provide optimal post-workout nourishment? Would it be more beneficial for me to drink something that is just whey and dextrose/maltodextrin?
Thanks for any guidance.
