Abstract
Vitamin D plays an important role in over-all health. Few data exist on vitamin D deficiency related with intake for a Canadian population. The purpose of this study is to assess vitamin D intake and status in healthy young adults of diverse ancestry during the wintertime.
One hundred and seven young healthy adults living in Southern Ontario were recruited during the late winter of 2007. Their serum 25-hydroxyvitamin D [25(OH)D], skin melanin and anthropometric measures were determined. They completed a food frequency questionnaire (FFQ) (twice) and a 7-day food diary. Correlation analyses and t-test were used to validate the FFQ against the 7-day diary and 25(OH)D; one way ANOVA was used to determine ethnic group differences in vitamin D intake and status.
The results indicated that the FFQ used in this study was valid. Vitamin D deficiency [25(OH)D
