Speaker: Dr. John Hoffer, Professor of Medicine, McGill University
Topic: "What is Orthomolecular Medicine? Is it Good? How do I Know?"
Dr Hoffer is an internationally recognized researcher into protein-energy malnutrition and using vitamins for chronic disease - including high-dose vitamin C therapy in cancer. Orthomolecular medicine seeks to maintain health and prevent diseases through nutritional intake and supplements.
He has a distinguished career in clinical medicine. He is a professor at McGill's Faculty of Medicine and an associate professor at McGill's School of Dietetics and Human Nutrition. He is also a senior physician in Internal Medicine and Endocrinology at Montreal's Jewish General Hospital; and project director at its research arm, the Lady Davis Institute for Medical Research. The Hospital and Institute are affiliated to McGill's Faculty of Medicine, all centres of excellence in Canadian health care.
Dr Hoffer earned his MD from McGill University and PhD in Human and Clinical Nutrition from MIT. He trained in internal medicine at McGill and in nutrition and metabolism at Harvard Medical School, MIT and Brandeis University. He is a Fellow of The Royal College of Physicians of Canada, and serves on the Nutrition and Metabolism Committee of the Canadian Institutes for Health Research.

Dr. John Hoffer honoured by Canadian Nutrition Society
The Lady Davis Institute (LDI) of the Jewish General Hospital is proud to congratulate Dr. L. John Hoffer, recipient of the 2012 Khush Jeejeebhoy Award. This award is conferred by the Canadian Nutrition Society (CNS) to Canadians who have made an extraordinary contribution to nutrition research that extends the role and impact of clinical nutrition practice.
As a project director at the LDI, senior physician in internal medicine and endocrinology at the Jewish General Hospital, and Professor of Medicine at McGill University, Dr. Hoffer has devoted his career to studying the impact of malnutrition on disease. An internationally known investigator, he is also a member of the JGH nutritional support team, which consults and organizes the provision of parenteral nutrition therapy for patients who are unable to properly ingest nutrients.
As a researcher, Dr. Hoffer has been a leader in understanding the application of evidence-based nutrition in the clinic. His current research interests include protein and micronutrient deficiencies in hospital settings and the risks and benefits of high dose vitamin C therapy in treating cancer.
Dr. Hoffer will receive the Khush Jeejeebhoy Award and present the plenary lecture at the CNS annual meeting in Vancouver next month.
Rejuve - Vitamin D, 25 May 2013 [cached]
"Earlier studies, both in our hospital and in other centres, demonstrated that the majority of acutely hospitalized patients have subnormal levels of vitamins C and D in their blood," said senior author L. John Hoffer, MD, PhD, an investigator at the Lady Davis Institute for Medical Research and a professor of medicine at McGill University in Montreal, Canada, in a news release.
"About one in five acute-care patients in our hospital have vitamin C levels so low as to be compatible with scurvy, [but] patients are rarely given vitamin supplements."
"Most physicians are simply unaware of the problem," Dr. Hoffer continued.
"The lack of any effect of vitamin D on mood is good evidence we are not dealing with a placebo response," Dr. Hoffer said. "This looks like a true biological effect."
Limitations of this study include small sample size, study dropout, and patient heterogeneity. In addition, 5 of the 32 study participants had already been prescribed a vitamin D supplement by their physician at the time of enrollment, and these patients were automatically assigned to the vitamin C treatment group.
"Our finding definitely requires follow up in larger studies in other centres," Dr. Hoffer concluded.
