People ask us if we need enzymes on a raw food diet... I answer that question as well as if oxalates are in green juice, what you should spend on Vitamix and more! Take some kind of digestive or systemic enzymes empty stomach. You should also take some sort of digestive enzymes along with raw food diets. Though raw foods are loaded with enzymes however, our digestive system is not able to digest raw food. So, it is suggested to take outside enzymes for proper digestion. Green juice contain lots of oxalates. So, it is recommended to stop taking lots of green juice. If we take lots of green juice, our calcium and mineral percentage in our body will be perfect, but oxalate level will shoot up. So, take moderate quantity of green juice.
