Key findings from North AmericanÃ¯Â¿Â½s first conference on the relationship between ultraviolet light from sunlight and vitamin D status suggest many Canadians may not be getting enough vitamin D.
Vitamin D is important for its role in bone health and prevention of bone fractures. In recent years there has been growing evidence that vitamin D may have a protective effect on some types of cancers as well.
Vitamin D is obtained by skin exposure to UVB radiation from sunlight, as well as through diet. In Canada, for most of the winter months, there is insufficient UVB radiation from sunlight to promote vitamin D production in the skin. With regard to diet, research indicates that many Canadians do not meet their needs for vitamin D from foods, especially those over 50 years of age.
In response to these most recent findings, the Canadian Cancer society suggests a little sun can go a long way in producing adequate vitamin D. In fact, a five-minute walk in the morning with no sunscreen may be all we need.
Dietary sources of vitamin D include fatty fish, such as salmon and sardines. Most vitamin D in the diet comes from fortified foods, including milk, margarine and plant-based beverages.
