Des menteries de scientifiques

Le windsor star sort les grandes nouvelles ce matin. "Vos livres en trop pourrait ne pas vous tuer!" Et ça étonne! Je l'ai appris sur le site d'un entraineur dont la newsletter va dans mes pourriels chaque semaine mais dont le titre m'a aujourd'hui attirée. Je peux comprendre le pauvre d'être outré par la nouvelle, lui qui jeûne un jour sur deux pour garder sa ligne et qui a fait de son obsession une carrière pour pouvoir mieux contaminer, euh aider, les autres. Selon lui les scientifiques qui ont fait cette études vous veulent du mal et essaient de justifier leur propre obésité.
Pendant ce temps, dans ce monde qui tourne rondement, Posh Spice doit reprendre du poids pour survivre a sa tournée avec les Spice Girls.

Mais maigrissez comme les filles sur les revues. C'est bon pour vous... Ouais.

Je rappelle à toutes que plusieurs spécialistes de la question croient que les maladies traditionellement liées à l'obésité avec lesquelles ont terrorise des populations entières découlent en fait des régimes.

Mais faites dont un bon régime pour être en santé comme les filles de la télévision...

Ah, je suis fatiguée, je laisse la place aux méchants scientifiques qui inventent des histoires pour que vous alliez illico vous empifrer chez Tim Horton pour que vous mourriez jeunes. Je parie qu'il sont de mèche avec Al Qaeda ou le KGB... De toute façon, si cette étude à autant de biais et de problèmes méthodologiques que toute celles qui prouve que chaque livre au dessus de l'anorexie vous rapproche de satan, bof...

Attention:

Extra pounds may not be killing you

Being overweight doesn't destine people to an early death, a major new study has found.

U.S. researchers who analyzed 2.3 million adult deaths found the overweight are not at increased risk of dying from cardiovascular disease or cancer -- including obesity-related cancers such as tumours of the breast, colon or pancreas.

And, carrying 20 to 25 extra pounds appears to lower the risk of dying prematurely from virtually all other causes compared to normal-weight people.

This varied group appears to include respiratory diseases such as bronchitis and emphysema, pneumonia, tuberculosis and other infectious diseases, blood poisoning, liver disease, falls, suicide, Alzheimer and Parkinson, though scientists haven't analyzed each individual disease.

The exception were kidney disease and diabetes, two of the fastest growing diseases in Canada.

The net result? Overweight "was associated with significantly decreased all-cause mortality overall," scientists from the U.S. Centers for Disease Control and Prevention write in this week's, Journal of the American Medical Association.

The modestly overweight -- but not truly obese -- may be better able to recover from infections or medical procedures, and more likely to survive certain diseases due to the "greater nutritional reserves or higher lean body mass" associated with higher weights, the researchers write.

Last week, the World Cancer Research Fund said one of the single most important things people can do to avoid cancer is to stay as thin as possible within the "healthy" weight range.

A second massive study released Tuesday -- this one involving 1.2 million British women aged 50 to 64 -- found that while obesity causes an estimated four per cent of all cancers in post-menopausal women, just one per cent of cancers were attributed to being overweight, though the risk was higher for some cancers than others, including endometrial and esophageal cancer.

WHERE FAT IS

But a Canadian expert on weight and health says what matters more than the total amount of excess fat is where that fat is located. The study is based on the body mass index, a measure of weight to height. "We know that many of the health problems related to obesity are not reflected in the body mass index -- they're related to abdominal obesity," says Dr. Arya Sharma, scientific director of the Canadian Obesity Network.

The study's lead author says their analyses show that the estimated numbers of excess deaths would be similar whether BMI, waist, waist-to-hip ratio or some other fat measure was used.

But overweight is a loose definition, Sharma says. "If you're eating a healthy diet and you're physically active and you have no problems related to that excess weight, well then don't worry about it."
