If you’re a Canadian 50 or older, you may not have high enough levels of vitamin D in your blood needed to preserve your bone strength, and to protect the health of your immune system.
(A healthy immune system both protects against infections, and doesn’t go rogue and attack your own body, as is the case in autoimmune diseases such as rheumatoid arthritis.)
Why are older Canadians at risk? And what can they do to ensure they’re getting enough of the so-called ‘sunshine vitamin’?
My heartfelt thanks to the interviewees who so generously shared their time and expertise:
- Dr. David Hanley, a professor emeritus in the Departments of Medicine, Community Health Sciences and Oncology, at the University of Calgary’s Cumming School of Medicine.
- Dr. Hassan Vatanparast, a professor in the College of Pharmacy and Nutrition, School of Public Health, at the University of Saskatchewan in Saskatoon.
