Sina McCullough

Dr. Sina McCullough is the author of Hands Off My Food. She holds a Ph.D. in Nutritional Science and a B.S. in Neurobiology, Physiology, and Behavior, both from the University of California at Davis. She was the Director of R&D for a supplement company and taught Biochemistry and Bioenergetics at UC Davis. Despite her knowledge, she developed an autoimmune disease, which prompted her to launch an investigation into our food supply. What she learned saved her life; she reversed the disease without the use of medication. Now, Dr. McCullough is dedicated to helping others avoid the health challenges she has faced.
