THE ANTIRACHITIC ACTIVATION OF FOODS AND OF CHOLESTEROL BY ULTRAVIOLET IRRADIATION

THE ANTIRACHITIC ACTIVATION OF FOODS AND OF CHOLESTEROL BY ULTRAVIOLET IRRADIATION As is well known, animals as well as infants can be protected from rickets by means of the ultraviolet radiations from the sun or the mercury vapor or carbon arc lamps. About a year ago I communicated to the American Pediatric Society experimental data which showed that similar results can be brought about in an indirect way—that the ultraviolet rays can endow inactive oils with antirachitic properties, and that rickets can regularly be prevented or cured by feeding such substances to rats.1 Linseed oil and cottonseed oil were cited as examples in which this remarkable metamorphosis had been brought about. Shortly thereafter, similar results were reported by Steenbock and his co-workers.2 Since that time a series of papers has been published from this laboratory showing that refined wheat flour, dry milk, vegetables and other foods can be rendered rickets-protective by short exposures to the radiations from the quartz http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA American Medical Association

Abstract

As is well known, animals as well as infants can be protected from rickets by means of the ultraviolet radiations from the sun or the mercury vapor or carbon arc lamps. About a year ago I communicated to the American Pediatric Society experimental data which showed that similar results can be brought about in an indirect way—that the ultraviolet rays can endow inactive oils with antirachitic properties, and that rickets can regularly be prevented or cured by feeding such substances to rats.1 Linseed oil and cottonseed oil were cited as examples in which this remarkable metamorphosis had been brought about. Shortly thereafter, similar results were reported by Steenbock and his co-workers.2 Since that time a series of papers has been published from this laboratory showing that refined wheat flour, dry milk, vegetables and other foods can be rendered rickets-protective by short exposures to the radiations from the quartz
