The long read: Decades worth of research proves that chemicals used to make bacon do cause cancer. So how did the meat industry convince us it was safe?
There was a little cafe I used to go to that did the best bacon sandwiches. They came in a soft and pillowy white bap. The bacon, thick-cut from a local butcher, was midway between crispy and chewy. Ketchup and HP sauce were served in miniature jars with the sandwich, so you could dab on the exact amount you liked. That was all there was to it: just bread and bacon and sauce. Eating one of these sandwiches, as I did every few weeks, with a cup of strong coffee, felt like an uncomplicated pleasure.
And then, all of a sudden, the bacon sandwich stopped being quite so comforting. For a few weeks in October 2015, half the people I knew were talking about the news that eating bacon was now a proven cause of cancer. You couldnt miss the story: it was splashed large in every newspaper and all over the web. As one journalist wrote in Wired, Perhaps no two words together are more likely to set the internet aflame than BACON and CANCER. The BBC website announced, matter-of-factly, that Processed meats do cause cancer, while the Sun went with Banger out of Order and Killer in the Kitchen.
The source of the story was an announcement from the World Health Organization that processed meats were now classified as a group 1 carcinogen, meaning scientists were certain that there was sufficient evidence that they caused cancer, particularly colon cancer. The warning applied not just to British bacon but to Italian salami, Spanish chorizo, German bratwurst and myriad other foods.
Health scares are ten-a-penny, but this one was very hard to ignore. The WHO announcement came on advice from 22 cancer experts from 10 countries, who reviewed more than 400 studies on processed meat covering epidemiological data from hundreds of thousands of people. It was now possible to say that eat less processed meat, much like eat more vegetables, had become one of the very few absolutely incontrovertible pieces of evidence-based diet advice not simply another high-profile nutrition fad. As every news report highlighted, processed meat was now in a group of 120 proven carcinogens, alongside alcohol, asbestos and tobacco leading to a great many headlines blaring that bacon was as deadly as smoking.
The WHO advised that consuming 50g of processed meat a day equivalent to just a couple of rashers of bacon or one hotdog would raise the risk of getting bowel cancer by 18% over a lifetime. (Eating larger amounts raises your risk more.) Learning that your own risk of cancer has increased from something like 5% to something like 6% may not be frightening enough to put you off bacon sandwiches for ever. But learning that consumption of processed meat causes an additional 34,000 worldwide cancer deaths a year is much more chilling. According to Cancer Research UK, if no one ate processed or red meat in Britain, there would be 8,800 fewer cases of cancer. (That is four times the number of people killed annually on Britains roads.)
The news felt especially shocking because both ham and bacon are quintessentially British foods. Nearly a quarter of the adult population in Britain eats a ham sandwich for lunch on any given day, according to data from 2012 gathered by researchers Luke Yates and Alan Warde. To many consumers, bacon is not just a food; it is a repository of childhood memories, a totem of home. Surveys indicate that the smell of frying bacon is one of our favourite scents in the UK, along with cut grass and fresh bread. To be told that bacon had given millions of people cancer was a bit like finding out your granny had been secretly sprinkling arsenic on your morning toast.
Vegetarians might point out that the bacon sandwich should never have been seen as comforting. It is certainly no comfort for the pigs, most of whom are kept in squalid, cramped conditions. But for the rest of us, it was alarming to be told that these beloved foods might be contributing to thousands of needless human deaths. In the weeks following news of the WHO report, sales of bacon and sausages fell dramatically. British supermarkets reported a 3m drop in sales in just a fortnight. (It was very detrimental, said Kirsty Adams, the product developer for meat at Marks and Spencer.)
But just when it looked as if this may be #Bacongeddon (one of many agonised bacon-related hashtags trending in October 2015), a second wave of stories flooded in. Their message was: panic over. For one thing, the analogy between bacon and smoking was misleading. Smoking tobacco and eating processed meat are both dangerous, but not on the same scale. To put it in context, around 86% of lung cancers are linked to smoking, whereas it seems that just 21% of bowel cancers can be attributed to eating processed or red meat. A few weeks after publishing the report, the WHO issued a clarification insisting it was not telling consumers to stop eating processed meat.
Meanwhile, the meat industry was busily insisting that there was nothing to see here. The North American Meat Institute, an industry lobby group, called the report dramatic and alarmist overreach. A whole tranche of articles insisted in a commonsense tone that it would be premature and foolish to ditch our meaty fry-ups just because of a little cancer scare.
Nearly three years on, it feels like business as usual for processed meats. Many of us seem to have got over our initial sense of alarm. Sales of bacon in the UK are buoyant, having risen 5% in the two years up to mid-2016. When I interviewed a product developer for Sainsburys supermarket last year, she said that one of the quickest ways to get British consumers to try a new product now was to add chorizo to it.
And yet the evidence linking bacon to cancer is stronger than ever. In January, a new large-scale study using data from 262,195 British women suggested that consuming just 9g of bacon a day less than a rasher could significantly raise the risk of developing breast cancer later in life. The studys lead author, Jill Pell from the Institute of Health and Wellbeing at Glasgow University, told me that while it can be counterproductive to push for total abstinence, the scientific evidence suggests it would be misleading for health authorities to set any safe dose for processed meat other than zero.
The real scandal of bacon, however, is that it didnt have to be anything like so damaging to our health. The part of the story we havent been told including by the WHO is that there were always other ways to manufacture these products that would make them significantly less carcinogenic. The fact that this is so little known is tribute to the power of the meat industry, which has for the past 40 years been engaged in a campaign of cover-ups and misdirection to rival the dirty tricks of Big Tobacco.
How do you choose a pack of bacon in a shop, assuming you are a meat eater? First, you opt for either the crispy fat of streaky or the leanness of back. Then you decide between smoked or unsmoked each version has its passionate defenders (I am of the unsmoked persuasion). Maybe you seek out a packet made from free-range or organic meat, or maybe your budget is squeezed and you search for any bacon on special offer. Either way, before you put the pack in your basket, you have one last look, to check if the meat is pink enough.
Since we eat with our eyes, the main way we judge the quality of cured meats is pinkness. Yet it is this very colour that we should be suspicious of, as the French journalist Guillaume Coudray explains in a book published in France last year called Cochonneries, a word that means both piggeries and rubbish or junk food. The subtitle is How Charcuterie Became a Poison. Cochonneries reads like a crime novel, in which the processed meat industry is the perpetrator and ordinary consumers are the victims.
The pinkness of bacon or cooked ham, or salami is a sign that it has been treated with chemicals, more specifically with nitrates and nitrites. It is the use of these chemicals that is widely believed to be the reason why processed meat is much more carcinogenic than unprocessed meat. Coudray argues that we should speak not of processed meat but nitro-meat.
