Ny fødevareskræmmekampagne: Forarbejdet kød påstås at medføre cancer

Challenge: Not a single epidemiological study credibly links meat-eating with cancer

Don’t believe me? Show me one. I’ll debunk it before your eyes.

Consider this excerpt from a November 2007 column I wrote for FOXNews.com about a report from the American Institute for Cancer Research claiming that processed meat caused cancer.

Consider the data presented for processed meat, which the AICR report claims to be too dangerous to eat.

Of the 17 study results concerning processed meat and colon cancer comparing high consumption to low consumption 15 are way below, and one is at the 100 percent-risk threshold. Thirteen studies aren’t statistically significant. Not only is the lone study claiming a risk above 100 percent (a reported 250 percent increase in risk) barely statistically significant, it has a margin of error four times the size of the reported risk.

Of the seven studies reporting a cancer risk per serving of processed meat, all reported risks are substantially below the 100 percent threshold. Four results are clearly not statistically significant and two are borderline insignificant.

On the basis of these dubious statistical results, the AICR report concludes that “processed meat is a convincing cause of colorectal cancer.” This is an appalling and unsupported conclusion.

Nothing has changed since this column,except perhaps that more junky studies have been published.

  1. I går var der på TV en udsendelse om pommes frites og den kræftfremkaldende akrylamid som stegningen frembringer. En hel lang udsendelse af med alle de sædvanlige halve sandheder og hele usandheder. Fik mennesker kræft af stadset? Nej – det vidste de ikke, men dyr gjorde, og så ikke et eneste ord om de mængder der skulle til at give dyr kræft, og slet ikke et noget om hvor mange pommes friter man skulle æde, for at få det.

    Sædvanlig rød livsglædedestruerende propaganda. Ikke andet. – og nu også bøffen! Vor herre i skuret. Hvornår går det op for de troende, at livet er farligt men dejligt, og at den værste fare i særklasse har vist sig at være socialisme.
