Red meat has a bad PR problem. Two recent meta-analyses—one published in 2009 and one in 2011—linked red meat consumption to increased colon cancer risk. In May, the American Institute for Cancer Research and the World Cancer Research Fund reaffirmed conclusions from an earlier comprehensive report, saying that the evidence for a relationship between red meat and colon cancer is “convincing.”
And it’s not just cancer; a study published just last week found that adults who consume 4 ounces of red meat per day have a 20 percent increased risk for developing diabetes.
The evidence strongly suggests that it’s a good idea for everyone to reduce their intake of red and processed meats. But from the animals’ perspective, this is not necessarily great news. That’s because many of these studies find that other animal foods—which can easily replace red meat in the diet—don’t carry the same risks. There is no compelling body of evidence to suggest that eating white meat raises cancer risk and, some research suggests that replacing red meat with white meat lowers risk. (This is not to say that white meat is itself protective or has any particular health benefits. It’s probably neutral and therefore lowers risk when it replaces harmful red meat)
People are likely to react to news about the dangers of red and processed meats by replacing these foods with other meats—from fish and chickens—and in the process cause suffering to many, many more animals.
Assuming that one steer provides around 450 pounds of meat, a person eating a pound of beef per week would be responsible for the death of one steer every 8 ½ years or so. Replace that pound of beef a week with a pound of chicken (assuming that the average chicken yields 2 pounds of meat) and the number of animals killed would be about 220 chickens over the same time period. In fact, even if the health-conscious, meat-shunning consumer chose to reduce her meat intake by 75 percent—eating just 4 ounces of meat per week and getting all of it as chicken flesh—she would still be responsible for the death of more than 50 birds over that 8 ½ year period.
And not only do more animals die when people replace red meat with chicken in their diet, but chickens and other birds live and die under conditions that are horrible even by the usual horrible standards of modern farming.
Red and processed meat consumption is a serious public health concern, and people need to know about the importance of reducing these foods in their diets. But publicizing every new study about the hazards of red meat doesn’t promote veganism; it promotes animal suffering. A message about a vegan ethic, on the other hand, is a double win. It helps reduce animal suffering while also encouraging people to eliminate hazardous foods from their diets.
Edited on 3/13/12 : A study just published online in the Archives of Internal Medicine found that all types of red meat are associated with increased risk for cancer and heart disease. Just 3 ounces a day of red meat was associated with a 13% increased risk of dying during the course of the study. The researchers also found that replacing red meat with poultry or low-fat dairy foods decreased risk as much or more than replacing it with legumes. This is another example of how a focus on the health risks of red meat in particular doesn’t necessarily translate to a positive vegan message.
