Blueberry-Flax Recovery Shake

I never thought to put flaxseeds in a smoothie until recently--Flax is to the first part of the 21st century what wheat germ was to the '80s. Of all the plants in the kingdom, flax has the highest level of omega-3, an essential fatty acid (considered essential because the human body cannot produce them). I concocted this smoothie after I had just finished a hard run (thanks Coach Kurt) and it was fairly hot outside. I wanted to make a smoothie that would fall under the "Raw, Vegan" category (though the "rawness" of acai powder is questionable...) full of antioxidants (found in the flaxseed, blueberries and raw Cocoa Powder) After taking the first bite, I thought to myself "wow, there is an elixir in my mixer! -LM
