Joel “I tried a mostly raw fruitarian diet for a few months (until I wasted away), and then a low FODMAP diet for a few years. These approaches benefited me in some ways, but seemed to damage me in others; I could not resolve the digestive discomfort.”
Rebekah “I am an overcomer of over ten autoimmune diseases, chronic lyme disease, chronic c-diff, multiple mood disorders, IBS, IBD, diverticulitis, and more. I love nature, holistic medicine, music, and elephants”
