I can understand the kefir benefits. My guy flora is very sensitive to change, and after a round of antibiotics this winter, I was drinking kefir like it was going out of style. I've found since giving up grains, my tummy is way more happy and doesn't require help. I've given up kefir for coconut and almond milk as smoothie bases.
Why 12 baby carrots in a smoothie? That seems like big source for carbs.
