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.

Today, in the Montreal Gazette, Dr. L. John Hoffer, a professor of medicine at McGill University and an internist and clinical nutrition support specialist at the Jewish General Hospital, has written a response to this claim. Dr. Hoffer notes that many of the articles on the study in question have broad omissions, and that they may needlessly frighten individuals who are trying to cope with cancer treatments.
Hoffer principally finds fault with the study, which appeared in Cancer Research, because it did not involve ascorbic acid, but rather dehydroascorbic acid. Ascorbic acid is the form of vitamin C that is found in supplements. The dehydroascorbic acid in the study was mixed with cells in a concentraction that does not exist in nature.
The fact is that many more studies have found just the opposite of this recent study,--namely, that vitamin C in combination with chemotherapeutic drugs actually aids in the destruction of cancer cells and protects noncancerous cells. Hoffer also points out that in another recent study, vitamin C increased the benefit of chemotherapy, while the addition of dehydroascorbic acid decreased it.

"About one in five acute-care patients in our hospital have vitamin C levels so low as to be compatible with scurvy," said lead researcher, Dr. John Hoffer, professor of medicine at McGill University, Canada.
"Patients are rarely given vitamin supplements. Most physicians are simply unaware of the problem. Subclinical deficiencies of vitamin C and D have each been linked to psychological abnormalities, so we examined that aspect in our clinical trial," added Dr. Hoffer.
"The lack of any effect of vitamin D on mood is good evidence we are not dealing with a placebo response," said Dr. Hoffer.
