So, I tried researching this but it proved to be quite unsuccessful. I've been on a smoothie kick lately, and I usually drink a huge one for breakfast every day. It's usually made of Sharon's coconut sorbet, fresh banana, frozen strawberries/mangoes/pineapple and a mixture of orange juice and apple juice. What else can I put in my smoothies and what exactly does it do for you/what are its health benefits? I know a lot of you use flax seed oil...but what about soy protein powders or spirulina and the such?
