Here is a video of Sun, who is 22 months old, drinking a kale smoothie.
I fill up my Vitamix blender with
1/3 c Nutiva hempseeds
1 tbsp of Pacifica Hawaiian Spirulina
1 date pitted
2 c chopped Lacinto Kale
2 tbsp of Health Alliance Lecithin
1 Avocado ( if you don’t have hempseeds)
2 tbsp of hempseed oil (add at the end of blending)
2 strips of raw papaya (or you could use fresh)
1 inch cube of ginger (crucial for digestion)
Fill blender up with water until you have about 2 inches of water from the top. Blend on high for about 1.5 to 2 minutes and you can add ice cubes to cool it down since it tends to get got. A high tech blender is crucial to blend the hempseeds finely.
