Vatanparast H, et al. - Researchers utilized nationally representative nutrition data from the Canadian Community Health Survey Cycle 2.2 (CCHS 2004) and CCHS Nutrition in 2015 to study patterns in dietary and total usual consumption of vitamin D among Canadians aged ≥ 1 year. They found a significant reduction in the usual consumption of vitamin D from food by 1 μg/d only in vitamin D supplement nonusers from 2004 to 2015. During this time period, a significant rise in the prevalence of vitamin D supplement use and percentage contribution of vitamin D from supplemental sources was noted (5.0% and 14.9%, respectively). A significant increment in the total usual consumption of vitamin D (food plus supplement) from 15.1 ± 0.3 μg/d in 2004 to 31.5 ± 1.8 μg/d in 2015 was reported in vitamin D supplement users. Overall, findings revealed an increase in the prevalence of vitamin D supplement use and the percentage contribution of vitamin D from supplemental sources over an 11-year period in the Canadian population.
