True, it was a painful winter. We were stuck in a cocoon of cold (some of us still are) with limited daylight to lift our winter-weary spirits. So maybe we shouldn’t be surprised that vitamin D has emerged as a central point of controversy. In a country with little, if any, opportunity to synthesize the vitamin in fall and winter, the seasons with the least amount of sunlight, we should know just how much of the sunshine supplement we really need.
Enter the latest debate about vitamin D, sparked by a series of advertisements in newspapers across the country (including this one) claiming that none of us are getting anywhere near the amount our bodies require if we adhere to Health Canada’s recommended intakes. Osteoporosis experts are being inundated with calls from confused patients. Dietitians of Canada has expressed its concern in a letter to Health Canada. And Canadians are wondering what to make of the bold assertion that Health Canada was wrong and that we actually need more – a whole lot more – vitamin D to ward off disease.
