Peter D'Adamo

Peter J. D'Adamo ND (bo 17 July 1956) is a practicing American naturopathic physician noted for his popular book series on the blood type diet. Co-authored by health writer Catherine Whitney, D'Adamo's books suggest that appropriate diet and lifestyle depend on an individual's blood type.

D'Adamo gained a Naturopathic Doctorate (ND) from Bastyr College, Seattle, in 1982, and works as a licensed naturopathic physician at the D'Adamo Clinic, based in Wilton, Connecticut. While studying for his doctorate, he decided to research the scientific basis of the work of his father, James D'Adamo, who authored the first books on the concept of blood group and diet.

In 1990, D'Adamo was awarded 'Physician of the Year' by The American Association of Naturopathic Physicians. He is Adjunct Clinical Professor for both the Southwest College of Naturopathic Medicine, Tempe, Arizona, and the National College of Naturopathic Medicine, Portland, Oregon.
