Childhood was not easy for Frank Davis. He suffered from several childhood diseases, including mumps, measles, and pneumonia. The repercussions of this left his immune system compromised.
As he moved into adulthood, those challenges didn't stop. In his early 40's he suffered through even more diseases like hepatitis (twice), mononucleosis (twice), and pneumonia again. Eventually, he was diagnosed with chronic fatigue syndrome. For an athlete, this was the worst-case scenario. For nine months, he struggled with chronic fatigue syndrome. During this time, he became obsessed with finding a cure. His research led him to a symposium entitled, "Food as your Medicine." He discovered that nearly every disease, illness, cancer, etc., could be linked back to a dietary deficiency. The phrase, "let food be your medicine, and medicine be your food," resonated with him.
