Les fascistes de la santé déroutés de nouveau

Comme presque toutes les recommendations de 'santé publique', celle de consommer plus de 5 portions de fruits et légumes par jour ne tient pas la route lorsque soumise à une étude sérieuse.

Peu importe, un des 2 auteurs de l'étude a déjà indiqué que les observations de cette étude n'invalidaient pas les recommendations actuelles de consommer plus de 5 portions de fruits et légumes par jour (voir plus bas).

La question à se poser, évidemment: si les résultats ne changent rien aux recommandations des 'authorités de la santé', pourquoi dépenser temps, argent et effort humain pour effectuer l'étude?

Et sur quoi sont basées ces recommendations?

'Five-a-day' has limited impact on cancer risk

Wed Apr 7, 6:01 AM

PARIS (AFP) - Eating lots of fruit and vegetables has only a small effect on warding off cancer,

a study published on Wednesday says, although its authors insist that tucking into the recommended

"five-a-day"is still good for general health.

Doctors led by Paolo Boffetta at the Mount Sinai Medical Center, New York, pored over eight years of

data from a major European investigation into the relationship between cancer risk and food.

The investigation, which is continuing, covers nearly 470,000 volunteers recruited in 10 Western

European countries.

Between 1992 and 2000, more than 30,000 of the participants were diagnosed with cancer.

Boffetta's team found that high consumption of fruit and vegetables gave only modest protection against

cancer.

An increase of 200 grammes (about seven ounces) a day resulted in a three-percent reduction of cancer

risk.

Vegetable consumption by itself also gave a small benefit, although this was restricted to women,

while heavy drinkers who ate a lot of fruit and veggies had a somewhat reduced risk, but only for

cancers linked to alcohol and smoking.

"The bottom line here is that, yes, we did find a protective effect of fruit and vegetable intake

against cancer, but it is a smaller connection than previously thought," Boffetta said in a press release

issued by Mount Sinai.

"Any cancer protective effect of these foods is likely to be modest, at best. However, eating fruits

and vegetables is beneficial for health in general and the results of this study do not justify changing

current recommendations aiming at increasing intake of these foods."

The UN's World Health Organisation (WHO) issued a recommendation in 1990 suggesting that five

servings of fruit and vegetables per day helped prevent cancer and other diseases.

"Worldwide, low intake of fruits and vegetables is estimated to cause about 19 percent of

gastrointestinal cancer, about 31 percent of ischaemic heart disease and 11 percent stroke,"

the WHO says on its website.

Ischaemic heart disease is caused by lack of blood supply to the cardiac muscles, typically as a

result of artery disease, hypertension, smoking or high cholesterol levels.

The new study appears online in the Journal of the National Cancer Institute, published by Britain's

Oxford University Press.
