Eating Bacon Can Kill You

A research division of the World Health Organization announced Monday that bacon, sausage and other processed meats cause cancer and that red meat probably does, too.
The report by the influential group stakes out one of the most aggressive stances against meat taken by a major health organization, and it is expected to face stiff criticism in the United States.
The WHO findings were drafted by a panel of 22 international experts who reviewed decades of research on the link between red meat, processed meats and cancer. The panel reviewed animal experiments, studies of human diet and health, and cell processes that could explain how red meat might cause cancer.
But the panel’s decision was not unanimous, and by raising lethal concerns about a food that anchors countless American meals, it will be controversial.
The $95 billion U.S. beef industry has been preparing for months to mount a response, and some scientists, including some unaffiliated with the meat industry, have questioned whether the evidence is substantial enough to draw the strong conclusions that the WHO panel did.
In reaching its conclusion, the panel sought to quantify the risks, and compared to carcinogens such as cigarettes, the magnitude of the danger appears small, experts said. The WHO panel cited studies suggesting that an additional 3.5 ounces of red meat everyday raises the risk of colorectal cancer by 17 percent; eating an additional 1.8 ounces of processed meat daily raises the risk by 18 percent, according to the research cited.
“For an individual, the risk of developing colorectal cancer because of their consumption of processed meat remains small, but this risk increases with the amount of meat consumed,” says Kurt Straif, an official with the World Health Organization’s International Agency for Research on Cancer, which produced the report. “In view of the large number of people who consume processed meat, the global impact on cancer incidence is of public health importance.”
About 34,000 cancer deaths a year worldwide are attributable to diets high in processed meats, according to figures cited by the panel.
The research into a possible link between eating red meat and cancer has been the subject of scientific debate for decades, with colorectal cancer being a long-standing area of concern. But by concluding that processed meat causes cancer, and that red meat “probably” causes cancer, the WHO findings go well beyond the tentative associations that some other groups have reported.
The American Cancer Society, for example, notes that many studies have found “a link” between eating red meat and heightened risks of colorectal cancer. But it stops short of telling people that the meats cause cancer. Some diets that have lots of vegetables and fruits and lesser amounts of red and processed meats have been associated with a lower risk of colorectal cancer, the American Cancer Society says, but “it’s not exactly clear” which factors of that diet are important.
