The jury is still out in regards to how exactly the carnivore/Lion Diet is aiding people in reducing or eliminating their environmental allergies, but it likely has to do with the healing of the immune system. I would recommend checking out wyndly.com for sublingual drops to help with environmental allergies. It does appear that allergies are caused by an overactive immune system and since the Lion Diet heals the gut (reason for overactive immune system) things “calm down” for numerous people. Many people report finally being able to breathe out both of their nostrils for the first time in their entire life.
