IT IS TIME EPIDEMIOLOGY TAKES A FEW STEPS BACK

The ink of the latest report from the World Cancer Research Fund and American Institute for Cancer Research urging us that in order to stay healthy we should maintain a body mass index as close to 18 as possible isn’t even dry yet, that a new study is now telling us that actually cancers are not associated with being somewhat overweight and higher weights are associated with better survivals when we get sick. How can we possibly trust any of the advice these so called scientists give us about our personal health? How can governments continue to rely on epidemiological studies to legislate? Isn’t it time epidemiology takes a few steps back and performs what it was meant to perform – studies of infectious diseases?

Clean your plate: a few extra pounds won't kill you

Weight helps to beat some illnesses, study finds
SHARON KIRKEY, CanWest News Service
Deaths studied were grouped into three major categories: cardiovascular disease, cancer and all other causes.
For each cause, the team estimated excess deaths in each category of body mass index, or BMI. A BMI of 25 to less than 30 is considered overweight; a BMI of 30 and over is obese.
Someone who is 5 feet, 10 inches tall and weighs 174 to 208 pounds would be considered overweight, according to their BMI. More than that, and they're obese.
Obesity - but not overweight - was strongly associated with an increased risk of dying from coronary heart disease, stroke or other forms of cardiovascular disease, accounting for 112,159 excess deaths in the United States in 2004.
The team estimates that obesity is associated "with somewhere between nine and 13 per cent of all cardiovascular mortality," said lead author Katherine Flegal, senior research scientist at the Centres for Disease Control in Hyattsville, Md.
Overall, the team found no association between obesity and cancer deaths when all cancers, including lung cancer, were grouped together.
"We're not trying to say overweight is protective," Flegal said, but there is some evidence higher weights are associated with better survival when you get sick.


We have in the past referred you to Sandy Szwarc’s , BSN, RN, CCP blog, who in her own words performs ‘’ Critical examinations of studies and news on food, weight, health and healthcare that mainstream media misses. ‘’ . She has analyzed the latest report from the World Cancer Research Fund and American Institute for Cancer Research that appeared this week in the news everywhere. Chances are you won’t read her analysis anywhere in the mainstream media so we invite you to read it at: http://junkfoodscience.blogspot.com/2007/11/jfs-exclusive-whats-evidence-cancers.html
