I have one every single day!....and I can tell a difference on the odd day here and there, when I don't have one. Most smoothies sold in restaurants, or food trucks are pure sugar...and not the natural kind. Most people don't realize how many things they think are "healthy" are loaded in added sugar...for example, skim milk. You might as well drink a glass of Kool-aid! As it turns out, if you take the fat out of milk...it tastes like shit! So....what happens...they add sugar! Same goes with most "alternative" milks (almond, cashew, etc.). If you're stuck on "milk like products", the best option is to make coconut milk yourself. Its super easy, and cheap, and tastes great!
