What was the meat industry’s response to leading cancer charities’ recommendation to stop eating processed meat, like bacon, ham, hot dogs, sausage, and lunchmeat? The industry acknowledges that the most recent international cancer prevention guidelines now urge people to avoid processed meat.
“It is evident that…such a statement represents ‘a clear and present danger’ for the meat industry,” reads one response in the journal Meat Science. Processed meat, it continues, is “a social necessity.” (How could anyone live without bologna?) The challenge for the meat industry, the response outlines, is to find a way to maintain the consumption of these convenience products while somehow not damaging public health.
We’re still not sure what in processed meat is so carcinogenic, but the most probable educated guess for explaining the damaging effect of processed meats involves heme iron, along with nitrosamine and free radical formation, ultimately resulting in carcinogenic DNA damage. To reduce the nitrosamines, they could remove the nitrites, something the industry has been considering for decades because of the long-known toxic effects they cause. The industry adds them to keep the meat pink. There are, evidently, other coloring additives available. Nevertheless, it’s going to be hard to get industry to change “in view of the positive effects” of these substances as preservatives and in achieving a “desirable flavour and red colour developing ingredients.” No one wants green eggs and ham.
It’s like salt reduction in meat products. The meat industry would like to reduce it, but “[o]ne of the biggest barriers to salt replacement is cost as salt is one of the cheapest food ingredients available.” A number of taste enhancers can be injected into the meat to help compensate for the salt reduction, but some leave a bitter after-taste. To address that, industry can also inject a patented bitter-blocking chemical that can prevent taste nerve stimulation at the same time. This “bitter blocker is only the first of what will become a stream of products that are produced due to the convergence of food technology and biotechnology.”
The meat industry could always try adding non-meat materials to the meat, such as fiber or resistant starch from beans that have protective effects against cancer. After all, in the United States, dietary fiber is under-consumed by most adults, “indicating that fiber fortification in meat products could have health benefits.” But, of course, the meat industry’s own products are one of the reasons the American diet is so deficient in fiber in the first place.
The industry is all in favor of reformulating their products to cause less cancer, but “[o]bviously any optimization has to achieve a healthier product without affecting quality, particularly hedonic aspects.”
“It is important to realise that nutritional and technological quality [in the meat industry] are inversely correlated. Currently, improvement in one will lead to deterioration of the other.” Indeed, the meat industry knows that consumption of lard is not the best thing in the world—what with heart disease being our number-one killer—but those downsides “are in sharp contrast to their technological qualities that make them indispensable in the manufacture of meat products.” Otherwise, you just don’t get the same “lard consistency.” The pig’s fat doesn’t get hard enough, and, as a result, “a fatty smear upon cutting or slicing can be observed on the cutting surface of the knife.” Less heart disease versus absence of that fatty smear? I suppose you have to weigh the pros and cons…
According to the World Health Organization’s IARC, processed meat is now a Group 1 carcinogen—the highest designation. How is it that schools still feed it to our children?
