The National Institute of Medical Sciences and Nutrition Salvador Zubirán, (INCMNSZ) is one of the National Institutes of the Mexican Ministry of Public Health that provides third level medical care for adults.

It opened its doors on October 12th, 1946 under the name of “Hospital for Nutrition Diseases”. However, in 1978, when it further developed its medical care to other fields and in recognition of its founder, the name of the hospital was changed to “National Institute of Nutrition Salvador Zubirán”. The name was preserved until June 2000, when the term “Medical Sciences” was also incorporated in its name in order to emphasize the nature of the Institution as a center of expertise dedicated to the comprehensive development of medicine.
