red meat and cancer risk study provokes industry reaction
|

large european study supports previous findings that suggests red and processed meat consumption increases the risk of colorectal cancer, fuelling immediate reaction from meat industry that claims the study fails to "prove cause and effect", reports lindsey partos. the eu wide research that spanned ten countries and tracked nearly half a million consumers concluded colorectal risk increases by 49 per cent per 100 grams of daily consumed red meat, to cover pork, beef, veal, and lamb. by contrast, their findings suggest that high fish intake may reduce the risk, although "existing evidence is less convincing," write the researchers. this latest study builds on accumulating research, first published in 1990, that indicate the link, although with nearly 500,000 participants, this is one of the largest cohorts of men and women to examine the relationship between diet and cancer. "the absolute risk of developing colorectal cancer within ten years for a study subject aged 50 years was 1.71 per cent for the highest category of red meat intake and 1.28 per cent for the lowest category," report the researchers based in academic institutions across europe, from lyon in france to german cancer research center in heidelberg. these figures, write the study authors, take account of the influence of different factors such as gender, body weight, alcohol comsumption, physical exercise or smoking on the disease risk. defending its industry, the american meat institute foundation immediately rejected the study and its findings, accusing the study of being epidemiological, " which means it does not prove cause," the industry body said in a statement yesterday. the group claims the study's relative risk of 1.71 should be viewed with 'sceptism' , and quotes the epidemiologist ernst wynder who, in the american journal of epidemiology in 1986, said relative risks under 3.0 are suspect. "we should not rush to judgment about a causative implication when in fact the word 'association' ought to be used," said wynder. the most important fact is that the larger body of evidence has shown processed meats are a healthy part of a balanced diet, added the american meat institute foundation yesterday. but researchers working on the european prospective investigation into cancer and nutrition (epic) claim the analysis is based on 1.329 cases of rectal and colon cancer that have been newly diagnosed among participants since the study begun. "study subjects who had eaten a lot of what is called "red" meat, or such meat products, were diagnosed with colorectal cancer more often than persons who ate only little of it," they report in the 15 june issue of the journal of the national cancer institute . people who eat diets rich in meat also tend to eat less fibre and less fish, they add. those who ate a lot of fish were found to have a significantly lower colorectal cancer risk compared to those with a low fish consumption. the consumption of poultry played no role for colorectal cancer incidence, they write. looking into the reasons behind their findings, the scientists propose different explanations: recent studies suggest that the intake of iron contained in meat may contribute to risk elevation, because iron can promote the formation of harmful nitroso compounds in the body. on average, red meat or meat products have a higher iron content than poultry, which may explain why consumption of the latter may not have influenced colorectal cancer risk in this study. the protective effect of fish consumption may be caused by specific long chain, polyunsaturated omega-3 fatty acids.

cutting back meat consumption is the new darling cause of pop stars. but if necessary environmental and health goals are to be achieved, the whole supply chain needs to be strumming along in tune. john mccartney, yoko ono and moby stepped out together on the ‘green carpet’ in june to launch the uk’s meat-free mondays campaign. over in belgium, the city of ghent has declared that public officials and school kids are to take a one-day holiday from meat eating each week.

diet and cancer are directly linked, with alcohol and red and processed meats posing particular risks, according to the world cancer research fund's (wcrf) study released this week. a panel of world-renowned scientists looked at 7,000 studies published since the 1960s. entitled food, nutrition, physical activity, and the prevention of cancer, the report includes 10 recommendations on how to prevent cancer.

new research supports previous findings that suggest a diet high in red meat could be a risk factor for cancer. high consumption of red and processed meats - but not fat or cholesterol -could raise the risk of pancreatic cancer, claim researchers at the cancer research center of hawaii. tracking 190,000 consumers over seven years through a multiethnic cohort study, the scientists say participants in the highest quintile of processed meat intake had a 68 per cent increased risk of pancreatic cancer compared with those in the lowest quintile.

a federal judge has dismissed a lawsuit filed last july against several hotdog makers by vegan advocacy group cancer project that claimed hotdogs should carry a cancer warning label. the cancer project, an affiliate of the physicians committee for responsible medicine, said it was acting on behalf of three new jersey residents and filed a class-action consumer fraud lawsuit, arguing that hotdogs should carry the following label: “warning: consuming hot dogs and other processed meats increases the risk of cancer\", after several studies linked the consumption of processed meat with higher cancer risk.

reduction of meat and dairy intake on climate change grounds would pose nutritional concerns for some nutrients but better public health advice on alternative sources and fortification could bridge the gap, write nutritional and climate experts from the uk. the food system is a major contributor to greenhouse gas emissions, with food supply thought to account for some 19 per cent of the uk’s emissions.

the big 'cs' got the meat industry in trouble last week - cancer and credibility. in the face of a major scientific study linking a 30 per cent increased risk of cancer with processed meat products, industry associations reacted quite strongly against the findings - when they would have been wiser to have just kept their mouths shut. the scientific review of 7,000 studies was completed for the world cancer research fund (wcrf) and the american institute for cancer research, very credible organisations.
