Dean Michael Ornish (born July 16, 1953) is a physician and president and founder of the nonprofit Preventive Medicine Research Institute in Sausalito, California, as well as Clinical Professor of Medicine at the University of California, San Francisco. He is known for his promotion of what he believes to be healthy diets, particularly vegetarianism.
Ornish, a native of Dallas, Texas, is a graduate of Dallas's Hillcrest High School. He holds a Bachelor of Arts summa cum laude in Humanities from the University of Texas at Austin, where he gave the baccalaureate address. He earned his M.D. from the Baylor College of Medicine, was a Clinical Fellow in Medicine at Harvard Medical School, and completed a medical internship and residency at Massachusetts General Hospital (1981–1984).
Ornish is known for his lifestyle-driven approach to the control of coronary artery disease (CAD) and other chronic diseases. He promotes lifestyle changes including a whole foods, plant-based diet, smoking cessation, moderate exercise, stress management techniques including yoga and meditation, and psychosocial support. He has acknowledged his debt to Swami Satchidananda for helping him develop this holistic perspective on preventive health.
This result was demonstrated in a randomized controlled trial known as the Lifestyle Heart Trial, with one-year data published in the Lancet in 1990, and five-year data published in the Journal of the American Medical Association, which recruited test subjects with pre-existing coronary artery disease. Not only did patients assigned to the above regimen fare better with respect to cardiac events than those who followed standard medical advice, their coronary atherosclerosis was somewhat reversed, as evidenced by decreased stenosis (narrowing) of the coronary arteries after one year of treatment. Most patients in the control group, by contrast, had narrower coronary arteries at the end of the trial than the start. Other doctors have claimed similar results with similar methods, for example: Caldwell Esselstyn, and K. Lance Gould.
This landmark discovery was notable because it had seemed physiologically implausible, and it suggested cheaper and safer therapies against cardiovascular disease than invasive procedures such as coronary artery bypass surgery, angioplasty, and stents.
Ornish also directed the first randomized controlled trial demonstrating that comprehensive lifestyle changes may slow, stop, or even reverse the progression of early-state prostate cancer. This study was done in collaboration with the Chairs of Urology at the time at UCSF (Peter Carroll) and Memorial Sloan-Kettering Cancer Center (William Fair).
In 2008, he published research in collaboration with Elizabeth Blackburn showing that comprehensive lifestyle changes affect gene expression in only three months, turning on disease-preventing genes and turning off genes that promote cancer and heart disease and increasing telomerase enzyme that lengthens telomeres, the ends of chromosomes which control ageing.
He is the author of six best-selling books, including Dr. Dean Ornish's Program for Reversing Heart Disease; Eat More, Weigh Less; Love & Survival and his most recent book The Spectrum.
He has been a physician consultant to former President Bill Clinton since 1993, when Ornish was first asked by Hillary Rodham Clinton to consult with the chefs at The White House, Camp David, and Air Force One to cook more healthfully. In 2010, after the former President's cardiac bypass grafts became clogged, Ornish met with him and encouraged him to follow a mostly plant-based diet, because moderate changes in diet were not sufficient to stop the progression of his heart disease, and he agreed. In contrast to Esselstyn, Ornish recommends the consumption of fish oil supplements and does not follow a strict vegetarian diet, allowing for the consumption of occasional animal products.
Ornish has written a monthly column for Newsweek and Reader's Digest magazines and is currently the Medical Editor of The Huffington Post. A one-hour documentary of his work was broadcast on the PBS science series NOVA. In addition to being featured on Bill Moyers' PBS series Healing & The Mind, his work is featured in a documentary film Escape Fire: The Fight to Rescue American Healthcare about transforming the future of healthcare with patient-centered, integrative medicine.
He was interviewed and featured in the mind body medicine documentary, The Connection. Released in 2014.
Awards and honors
Ornish is a member of the boards of directors of the San Francisco Food Bank and the J. Craig Venter Institute. Additionally, he is a member of the boards of directors of the U.S. United Nations High Commission for Refugees and the Quincy Jones Foundation. He is an advisory board member of HealthCorps. He was appointed to The White House Commission on Complementary and Alternative Medicine Policy and elected to the California Academy of Medicine.
He chaired the Google Health Advisory Council from 2007 through 2009.
He has received several awards, including the 1994 Outstanding Young Alumnus Award from the University of Texas, Austin; the University of California, Berkeley, “National Public Health Hero” award; the Jan J. Kellermann Memorial Award for distinguished contribution in the field of cardiovascular disease prevention from the International Academy of Cardiology; a Presidential Citation from the American Psychological Association; the Beckmann Medal from the German Society for Prevention and Rehabilitation of Cardiovascular Diseases; the “Pioneer in Integrative Medicine” award from California Pacific Medical Center; the Stanley Wallach Lectureship Award from the American College of Nutrition; the Golden Plate Award from the American Academy of Achievement; the Linus Pauling Award from the Institute for Functional Medicine; the Glenn Foundation Award for Research in Aging; the Bravewell Collaborative Pioneer of Integrative Medicine award; and the Sheila Kar Health Foundation Humanitarian Award from Cedars-Sinai Medical Center (Los Angeles).
He regularly gives keynote speeches on his findings, and has spoken at the White House, the Google Zeitgeist conference, as well as the Institute of Medicine’s first Summit on Integrative Medicine at the National Academy of Sciences.
Ornish was recognized as “one of the most interesting people of 1996” by People magazine; selected as one of the “TIME 100” in integrative medicine; honored as “one of the 125 most extraordinary University of Texas alumni in the past 125 years;” chosen by LIFE magazine as “one of the fifty most influential members of his generation;” and by Forbes magazine as “one of the seven most powerful teachers in the world.”
Many of Dean Ornish's statements about good nutrition have been disputed in an article in the magazine Scientific American.
