My favorite smoothie includes a small beet. If you want to feel totally cleansed inside, beet is the magic bullet. Although I have been using ground flax seed as extra fiber, it pales in comparison with a beet. Furthermore, beets are so sweet, they add mounds of succulent sweetness in a natural way.
Typical Beet Smoothie recipe:
1 small beet
1 cup water
2 Tbsp ground flax seeds
1/3 cup apple juice
1/2 cup frozen blueberries
2 kale leaves or any leafy green of choice
either a handful of cranberries, pomegranate seeds or another fruit, like mango.
Blend all ingredients in a blender and enjoy.
Your life will never be the same!
