What's your blood type?
The key to biochemical individuality.

Jenny has her father's blue eyes and her mother's straight hair. She will grow to five feet, five inches tall. But Jenny's height won't tell her how well she'll be able to digest and absorb one food over another. Her blue eyes can't tell her what disease susceptibilities she may need to watch out for. And her hair texture won't tell her the best ways to keep her body energetic, healthy and strong as she ages. There is one simple and inexpensive genetic biomarker that will tell Jenny all these things and more: her Blood Type.


Hello and welcome to official website of Dr. Peter D'Adamo and home of the original nutrigenomic diet.

In the News:
Personalized Medicine Shift

Dr. D'Adamo's Teaching Shift offers expert guidance, materials and followup services at reasonable cost.


Dr. D'Adamo supervises a teaching shift in personalized medicine through the University of Bridgeport College of Naturopathic Medicine. The shift typically consists of five student clinicians and one resident physician, supervised by Dr. D'Adamo. Because it is a teaching shift, visit costs are considerably lower than seeing Dr. D'Adamo as a private patient. Patients also benefit from the added depth of communication and information that accompanies the teaching experience.

The shift blends time-honored natural healing techniques with state-of-the-art diagnostics and proprietary software personally written by Dr. D'Adamo to develop a genetically tailored diet specific for each patient.
