@EatingWell User you obviously missed the "if desired" part of the recipe. ANY sweetener (natural preferably) will suffice. Just enjoy the smoothie as is if you have a problem with sugar. Small amounts are fine, this isn't a candy or breakfast bar laden with sweeteners.
As for the recipe, we love the very simple, on-the-go aspect of the smoothie itself. We did find the buttermilk added an necessary tartness. However, as m.d0d83 pointed out, milk subs are perfectly fine as preferences dictate taste. Nicely done!
