In Canada we get a lot of stories in the news about obesity in the US and sometimes I thing that we look at ourselves as immune to the obesity issue. Of course that is not at all true and bad habits in the US are the same as the bad habits in Canada. While many people look at the magic BMI number of 30 as the divider of obese or not (I of course hate the whole BMI numbering) I found this article in the Calgary Herald newspaper here in Canada.

According to the 2004 Canadian Community Health Survey, 2.7 per cent of the population had “class III” obesity, meaning a BMI of 40 or more. But Padwal and others believe the prevalence of extreme obesity is now closer to four or five per cent, or about 1.5 million Canadians who are severely obese. Read the rest of this entry »

Looking to make a change and lose some weight? I have reviewed the top diet on the internet and you can go and read over 200 comments people have made about why this diet has worked well for them, as well as some of the problems.

The four-year study out of Creighton University in Nebraska found that women who regularly took vitamin D3 had a 60 per cent reduction in cancer infections compared to a group taking placebos.

The study followed 1,179 healthy, women 55 years and older from rural eastern Nebraska between 2000 and 2005. Participants were randomly assigned to receive 1400-1500 mg of calcium alone, or supplemental calcium plus 1,100 IU vitamin D3, or placebo.

The researchers studied only vitamin D3, which comes from animal sources and seems to be more active than vitamin D2, which is derived from plant sources.

Among the 288 women taking placebo, 20 developed breast, colon, lung or another form of cancer. Among the 445 women taking just calcium, 17 developed cancer. But among the largest group — the 446 women taking vitamin D daily — just 13 developed cancer.

“What we found is that a vitamin D supplement decreased the cancer incidence in postmenopausal women by about 60 per cent,” lead investigator Joan Lappe, an associate professor of both medicine and nursing at Creighton University

This is not the first time that researchers have noted the health benefits of vitamin D. In February, two studies found that the vitamin was linked to lower rates of breast cancer and colorectal cancer. The “sunshine vitamin,” as it’s sometimes called, has also been shown to kill some cancer cells in laboratory experiments.

“There’s a lot of evidence out there that populations in first world countries are deficient in vitamin D and if you give them more, we can prevent cancers and other diseases that have been reported to be prevented with vitamin D,” said Lappe.

Humans can absorb vitamin D when ultraviolet rays from the sun trigger vitamin D synthesis in our skin. But because of our short summers in Canada and our latitude, most Canadians don’t get anywhere near enough of it all year long.

Because of the growing body of evidence about vitamin D, for the first time, the Canadian Cancer Society is recommending a specific amount of supplementation for Canadians to consider taking. The Society is now recommending that:

-Adults living in Canada should consider taking vitamin D supplementation of 1,000 international units (IU) a day during the fall and winter.

-Adults at higher risk of having lower vitamin D levels should consider taking vitamin D supplementation of 1,000 IU/day all year round. This includes people who are older; with dark skin; who don’t go outside often, and who wear clothing that covers most of their skin.
At this time, the Canadian Cancer Society does not have a recommendation for vitamin D supplementation for children.

“The evidence is still growing in this area, but we want to give guidance to Canadians about this emerging area of cancer prevention based on what we know now,” said Heather Logan, director of Cancer Control Policy with the Canadian Cancer Society.

“We’re recommending 1,000 IUs daily because the current evidence suggests this amount will help reduce cancer risk with the least potential for harm,” said Logan.

“As we find out more we will update our recommendation.”

Logan cautions Canadians about relying too much on getting vitamin D through exposure to sunlight.

“It’s not a good idea to rely solely on the sun to obtain vitamin D,” said Logan. “For some people, it’s possible that just a few minutes of unprotected sun exposure every day could increase skin cancer risk.”
