John E. Lewis, Ph.D.
John E. Lewis, Ph.D. is past full-time and current Voluntary Associate Professor in the Department of Psychiatry and Behavioral Sciences at the University of Miami Miller School of Medicine and the Founder and President of Dr Lewis Nutrition™. He is a Diplomate, Faculty Member, and Advisor of the Medical Wellness Association. He has been the principal investigator of over 30 different studies in his research career. During that time, he either directly raised or indirectly supported raising over $23 million in grants, gifts, and contracts for research studies and clinical trials and educational programs for medical students. Much of his research has focused on evaluating the effects of nutrition, dietary supplementation, exercise, and medical devices on various aspects of human health and disease. He and his colleagues have been continually searching for ways to help people achieve and maintain health through natural treatments that align with our physiology.
In addition to his research, Dr. Lewis has been an invited national and international lecturer and guest speaker at conferences and as a guest on television shows, where he discusses not only the findings of his research, but to provide guidance and recommendations as an expert in the field of health and wellness. In addition, he has over 180 peer-reviewed publications in scientific journals, where his work has first appeared in print, including in some of the leading scientific journals, such as AIDS and Behavior, American Journal of Clinical Nutrition, American Journal of Public Health, Journal of the International AIDS Society, Journal of Strength and Conditioning Research, Nutrition and Cancer: An International Journal, Sports Medicine, Stroke, The Journal of Alternative and Complementary Medicine, and The Gerontologist. He has also mentored many different students, from undergraduates to post-doctoral trainees, in not only how to conduct clinical research but to apply the principles of health promotion into daily practice. A primary stimulus for the origin of Dr Lewis Nutrition™ occurred when Dr. Lewis ran his landmark study on how an aloe polysaccharide multi-nutrient complex improved cognitive and immune functioning after 12 months in persons with moderate to severe Alzheimer’s disease, leading to the creation of the dietary supplement, Daily Brain Care. Between 5 and 6 million Americans (approximately 40 million worldwide) suffer from Alzheimer’s disease today, and the Alzheimer’s Association predicts that number to more than double by 2030. It is the 6th leading cause of death of Americans and has no known conventional medical treatment, prevention, or cure. The current combined paid-for-care (formal) and unpaid care (informal caregiving) costs associated with Alzheimer’s are estimated to be over $500 billion per year, and the five FDA-approved drugs for dementia do little to improve the victim’s condition. Thus, Daily Brain Care shows more efficacy as a dietary supplement than what are considered to be the best evidence-based medications. His seminal publication from the study in the Journal of Alzheimer’s Disease, not only spurred him to leave academics and pursue a science-based business career, but also enabled him to be selected for a widely-acclaimed TEDxMiami talk about how dietary supplementation can improve brain health.
Dr. Lewis also embodies the model of health and wellness by eating a whole-food, plant-based diet for over 25 years, taking certain key dietary supplements, and through a rigorous, daily exercise training program.
John has a passion for educating others about the value of nutrition, exercise, and health, and he will continue to study the application of clinical nutrition for the benefit of mankind.
