Published last month in the American Journal of Epidemiology, the study found that one in seven young Canadian adults have vitamin C deficiency and one in three has "less than optimal" levels of vitamin C. The study involved 979 Toronto-based participants between the ages of 20 and 29.

 "Our research found that 47 per cent of young Canadian adults have deficient or sub-optimal blood levels of vitamin C, which is associated with adverse health effects," said El-Sohemy, senior researcher of the study.

The deficiency was associated with elevated markers of chronic disease and obesity, including a "significantly" higher waist circumference, body mass index, inflammation and blood pressure.
