Your Call Radio recently had a Show on the Topic: How Diet Affects Our Health. Guests included: Matthew Lederman, physician and co-founder of Exsalus Health and Wellness Center, Los Angeles, California and Dr. Caldwell Esselstyn, director of cardiovascular disease reversal and prevention at the Cleveland Clinic.
