Sodium food sources in the Canadian diet.

The purpose of this study is to provide information on the current sources of dietary sodium in the Canadian food supply to provide a baseline to measure against the effectiveness of strategies to reduce salt consumption. Such strategies are being developed by a Health Canada-led multistakeholder Working Group. Data from the 2004 Canadian Community Health Survey (CCHS) 2.

Dietary reference intakes for vitamin D: justification for a review of the 1997 values.

Recent Institute of Medicine (IOM) reviews of the process for deriving Dietary Reference Intakes (DRIs) suggest that determining the need for a new nutrient review should be evaluated against criteria set a priori. After selecting the criterion of significant new and relevant research, a working group of US and Canadian government scientists used results from a systematic review and 2 conferences on vitamin D and health to evaluate whether significant new and relevant scientific evidence had become available since the 1997 IOM publication of the DRIs for vitamin D. This working group concluded that there appears to be new research meeting the criteria for 4 key DRI questions.
