Processed Meat and Cancer Linked - World Health Organization

A headline-grabbing announcement this Monday 26, 2015, regarding meat and cancer - the World Health Organization (WHO) says processed meats like hot dogs, bacon and so on can cause cancer. That is according to a committee of scientists at the WHO. The organization will now list processed meats in the same risk category as tobacco and asbestos. The report shows how the panel of scientists came to this decision and how to think about these findings when you decide what to eat.

In order to determine the potential risks of processed meats and aÓÓ red meats, a group of 22 scientists pored oνer the findings of a whole bunch of long-term studies. And when they put the body of evidence together, they found that people who consume the highest levels of processed meats, such as bacon, hot dogs, and sausages, have an increased risk of developing colorectal cancer.

The experts noticed that there is consistent evidence that processed meat intake is linked to higher risk of cancer.

They recalled that actually, these findings are nothing new. These studies have been out for several years. What is new is the World Health Organization, the body many countries look to for health advice, using its megaphone to get people to pay attention. And now that many people are aware, the question lots of us have is, what does it mean to me? Should I reconsider how much meat I eat?

To put the risk in perspective, Andrew Maynard who directs the Risk Innovation Lab at Arizona State University added that there are many things we are exposed to that elevate our risk of developing some sort of cancer. Being exposed to sunlight and breathing polluted air are just a few examples of cancer-causing things that many of us face eνery day.

Now, this does not mean that a little bit of sunlight or a little air pollution will harm us. Generally, the risk increases with the amount of exposure. And this is true for meat consumption too. So the take home from this WHO report is that if you are eating excessive amounts of meat, you might want to cut back a little bit.

However, to be clear, the evidence linking hot dogs and other processed meats to cancer is stronger than the evidence linking aÓÓ red meat - things like cuts of beef, pork or lamb - to a cancer risk.

The experts found instead that the associations with cancer for unprocessed red meat are much weaker and much less consistent than for processed meats.

This means that a recommendation to cut back makes sense. Once in a while, you might want to have a BLT. Once in a while, you might want to have a pastrami sandwich. I think, you know, as a once in a while thing, the size of the risk is fairly small and, you know, you cannot tell people to not eat something ever.

The World Health Organization stopped short of saying what a safe amount of red or processed meat is, as there's not great evidence to give a specific amount or an exact target. Currently, Americans eat, on average, about a quarter pound of red meat per day. But there is a lot of variation from heavy meat-eating Paleo followers to vegans, who eat no meat at all.

Thus the panel recommends no more than one or two servings per month of processed meats and no more than two servings per week of unprocessed red meats.

Of course, the meat industry does not agree with the recommendations to eat less meat. And Janet Riley of the North American Meat Institute says that: “These new classifications from the World Health Organization are flawed. Red meats are instead healthy source nutrition. And moreover, the benefits of the protein, the iron, the zinc, the B vitamins that are in meat products far outweigh any theoretical risk.

According to Allison Aubrey, in making its determination, the panel of scientists at the World Health Organization did however point to these benefits. But it seems also clear for the panel that the science points to risks. And to minimize the cancer risk, the advice from many health organizations is to limit your consumption of red meat.
