KELOWNA, BC, June 1 /CNW/ - In support of the 2nd annual Tan Awareness
Week June 1-8, the Joint Canadian Tanning Association (JCTA) is asking the
Canadian Cancer Society to encourage Canadians to check their vitamin D blood
levels, the same way it encourages skin cancer screening.
The call comes in light of overwhelming evidence that reveals sun
avoidance and overuse of sunscreen has caused widespread vitamin D deficiency
in Canadians. Growing evidence suggests vitamin D deficiency is linked to
several types of cancer.
Tan Awareness Week is an educational campaign designed to encourage
intelligent sun care and sunburn prevention, rather than total sun abstinence.
The initiative was devised to dispel public health misinformation regarding
sun exposure which has contributed to a near-universal deficiency of vitamin D
among Canadians. Often called the "sunshine vitamin", vitamin D is made
primarily when UVB in sunlight reaches the skin.
UVB in sunlight is by far the most natural and abundant source of vitamin
D, and dietary supplements are unnatural surrogates for what human biology
intended: regular UV exposure.
The JCTA's call for vitamin D blood testing is supported by the following:
- The Canadian Cancer Society recognizes "there is growing evidence
vitamin D may reduce the risk of some types of cancer, particularly
colorectal and breast cancers."
- Studies continue to show up to 97 per cent of Canadians are vitamin D
deficient at some point during the year. A University of Toronto
study this year found 83 per cent of Canadian toddlers were vitamin D
- Few Canadians know their vitamin D levels. At least 91 per cent of
Canadian women don't know their vitamin D levels, according to a 2008
IPSOS-Reid survey commissioned by vitamin D advocate Marc Sorenson.
The survey also showed 77 per cent of women are not having a regular
vitamin D blood test, also known as a calcidiol test.
- University of Toronto vitamin D scientist Dr. Reinhold Vieth and
29 other international vitamin D scientists supporting Grassroots
Health's D(*)action campaign calling for vitamin D testing, recommend
vitamin D blood levels of 100-150 nmol/L (40-60 ng/ml).
"We are asking the Canadian Cancer Society to work in conjunction with
the Canadian Dermatology Association during Sun Awareness Week June 8-14 to
encourage and perform a simple blood spot test for vitamin D alongside skin
cancer screenings performed that week," says JCTA Executive Director Steve
Gilroy. "We are concerned overzealous warnings regarding sun exposure and the
use of sunscreen have resulted in the unintended consequence of vitamin D
deficiency. An initiative encouraging vitamin D blood spot testing would go a
long way to reduce this risk."
The JCTA encourages sunscreen use only when sunburn is a possibility.
Aside from preventing sunburn, there is no data to support that daily use of
sunscreen is necessary. "There is no direct data about the effect of
sunscreens on melanoma and basal cell cancers," according to the U.S. Center
for Disease Control. The World Health Organization has issued a similar

The Joint Canadian Tanning Association (JCTA) is a national non-profit
organization created to increase understanding of the professional tanning
industry's scientifically supported position that regular moderate
ultra-violet exposure from sunshine or sunbed in a non-burning fashion is part
of a responsible lifestyle that recognizes both the inherent benefits and the
manageable risks associated with ultraviolet light exposure.
