Dr Jeejeebhoy was guest speaker at the 16th annual Research Day for Dietetic Interns held at Ryerson University, Toronto, in September 2010. This learning event and archived presentation was made possible through the Ontario Dietetic Educators Leadership Forum of Ontario, a Dietitians of Canada Action Group.
