Red meat & cancer & very bad journalism
I am struggling to think of a diet & health story, which has been reported worse than the one dominating the press this week – and there tends to be at least one in the press every day. The newspapers seem to think that “artery-clogging” is an adjective to precede either, or both, of the words “cholesterol” and “fat” – whereas “life-vital” would be more appropriate words.
The story on red meat and cancer has to take the biscuit, however…
The story started to break on 20 February 2011 – we were forewarned that a report from the Scientific Advisory Committee on Nutrition (SACN) was about to be released. “Red meat does increase cancer risk, new report will confirm” screamed the Daily Mail headline. The article opened with the following three sentences:
“Britons should cut their consumption of red and processed meat to reduce the risk of bowel cancer, scientific experts are expected to recommend in a report.”
“The Scientific Advisory Committee on Nutrition (SACN) was asked by the Department of Health to review dietary advice on meat consumption as a source of iron.”
“In a draft report published in June 2009 the committee of independent experts said lower consumption of red and processed meat would probably reduce the risk of colorectal cancer.”
So, SACN was asked to look at meat consumption as a source of iron and are going to conclude instead that lower consumption of red and processed meat would probably reduce the risk of colorectal cancer (bowel cancer)? (All the emphases are mine).
Notice how red meat has become red and processed meat – could these two substances possibly be more different? Real meat (by weight) is the most nutritious food on the planet – offal is best, red meat next best and white meat the next best for essential fats, essential proteins (amino acids), vitamins and minerals. Processed meat should not be ingested by a human being – full stop. Putting these two together is like putting drinking water and coca-cola together or sardines and sugared, breaded fish sticks. This is irresponsible and ignorant in the extreme.
Then notice the word probably – despite the fact that SACN were asked to look at meat and iron – we expect them to recommend that lower consumption will probably … No one reads that caveat – the damage is done in the sensational headline screaming out from every newspaper and on line news tweet on the 20 February.
So, 25 February 2011 arrives and the SACN report is published. All 374 pages of a report called Iron and Health – all about – Iron and Health!
The headline writers obviously don’t read the report – we know the headline already – “red meat causes cancer”.
BBC Breakfast kicks off the day of meat demonisation. Dr Alison Tedstone is the spokesperson from the Department of Health and she doesn’t slip up during the interview in her careful use of the words “red and processed meat.” She specifically says: “Our experts have said that there’s a probable link between red and processed meat and bowel cancer.” Note that probable and red and processed again. Plus note the word link – there is no causation being claimed – so, there might be a link between one terrific food and one evil food and bowel cancer? Um – I wonder which one might be the problem. The fab Susanna Reid starts to ask the right question “Why would red meat?…” and then corrects this to “why would red and processed meat be a particular problem?” Tedstone says that there are a number of “plausible” mechanisms by which “red and processed meat” “might be a problem”, “we don’t exactly know why…” But, despite not knowing why, we are then told to limit our red and processed meat consumption to around 70g per day – approximately 2 slices of meat a day. Boy, those cavemen should have been dropping like flies.
The London Evening Standard was one of the first to run the story: “Eat less meat: Government experts warn Britons.” Experts from the SACN are expected to tell consumers to eat no more than 70g of “red or processed meat” a day. The headline says meat; the first sentence adds “or processed” in straight away. Is that because processed meat is the real killer? Does the sentence not hold if we just talk about meat?
The article goes on: “Some 1,900 cases of bowel cancer could also be prevented through cutting red meat consumption to under 70g per week.” Hang on a minute – how so?! The very next sentence describes the process by which processed meat is chemically altered. The sentence after says: “It is thought this process causes the formation of carcinogens, which can damage cells in the body and allow cancer to develop.” I have little doubt that processing meat causes carcinogens which can damage cells etc. But Ermentrude, out in the field near my house, grazing on fast growing grass in the Welsh rain and occasional sun – surely Mother Nature didn’t put her there to kill me?
The Evening Standard article ends with two telling sentences:
“Last year, experts from the Harvard School of Public Health in the US found that eating processed meats can increase the risk of heart disease and diabetes… However, unprocessed red meats, such as beef, pork or lamb, do not raise the risk, the study found.” So there is a difference between real meat and processed meat – we’ll just leave it to the end to point it out. This is disgraceful reporting.
BBC weren’t content just with TV coverage. They ran a story and tweeted on it in the morning – no doubt as a matter of urgency – I guess we need to know before we choose our lunch? “Eat less red meat to reduce cancer risk” the story instructed. First sentence? You guessed it: “People should cut back on red and processed meat to reduce their risk of getting cancer, the government says.”
Then the Department of Health tweet arrived: “Red meat link to bowel cancer.” Followed by the, now very familiar: “It (SACN) concludes that red and processed meat probably increases the risk of bowel cancer…”
At this point it is important to go to the original source and see what SACN actually said. I haven’t read all 374 pages – I usually start any report with the conflict of interest and then look at the summary. If anything in the summary is not clear – you can always delve deeper.
The conflict of interest is always interesting. In this case we have the chairman, Professor Peter Aggett with the SACN 2008 annual report declared interests as: Astra-Zeneca; Nestec; ILSI (I cover this ‘sugar protecting’ body in my book “The Obesity Epidemic“), Wellcome; Yakult and Cadbury Schweppes. The vice chair, Dr Ann Prentice, has declared interests as: Institute of Brewing & Distilling; Mars; National Association of British & Irish Millers; Optimal performance limited; Tanita; Coca-Cola; The Beverage Institute for health and wellness (yes, really) and Weight Watchers. Professor Sue Fairweather-Tait has declared interests in Coca-Cola, GlaxoSmithKline, British Egg Information Service, Unilever and Totus Medica. Those are the worst.
The headlines of the report are then:
– In a 1998 Department of Health report, the COMA (Committee on Medical Aspects of Food & Nutrition Policy – the predecessor for SACN) “highlighted possible links between red and processed meat and colorectal cancer”. Since red meat is an important source of iron in the human diet, SACN were asked to look at “the possible associated adverse implications of a reduction in meat consumption on other aspects of health, particularly iron consumption.” That was the brief – the possible link between processed meat and bowel cancer had been mentioned 13 years ago.
– The Terms of Reference were (and I quote) “To review the dietary intakes of iron in its various forms and the impact of different dietary patterns on the nutritional and health status of the population and to make proposals.” Hence calling the report “Iron and Health” – ‘cos that’s what it’s about.
– SACN started off the report with a bunch of excuses for why it has taken 13 years to write a report, which is so critical that the BBC needs to tell us (the wrong headline) about it twice before lunch.
– The conclusion of their task was as follows: “The modelling exercise indicates that reducing total red meat consumption (*) of consumers in the upper range of the distribution of intakes, down to 70g/day, would have little effect on the proportion of adults with iron intakes below the LRNI” (Lower Recommended National Intake).
(*) Note – in this paragraph (30) “Red and processed meat” is mentioned three times in as few lines before this summary sentence that seems to change this to “total red meat”. It is clear that red and processed meat is what we’re talking about. The title above para 30 is “The potential impact of reducing red and processed meat consumption on intakes of iron and zinc.”
Paragraph 36 reiterates that there is merely a possibility of a link between red and processed meat and bowel cancer. The logic then goes:
– “red and processed meat is a source of iron”
– “it is not possible to quantify the amount of red and processed meat that may be associated with increased colorectal cancer risk“
– “It may be advisable for adults with relatively high intakes of red and processed meat to consider reducing their intakes”
– “Modelling indicates that this would have little effect on the proportion of adults with iron intakes below the LRNI”
So, we’re not worried about population iron intake if the high red and processed meat consumers cut back.
And that’s what the SACN report was about.
But, never let the science get in the way of a good story…
Red meat is going to kill you!

Hi Zoe, I just found this post of yours as I was seeking some dirt on Dr Alison Tedstone, spokesperson for the Dept of Health whom you mentioned re the red meat and processed meat nonsense back in 2011.
I was looking for this as I have been invited to attend a Royal Society of Medicine conference on convincing people of the value and acuracy of govt dietary guidelines. You and I know very well that these dietary guidelines are ridiculous and harmful to the health of the nation’s people, so I looked at a couple of the contributors to this attempt of scientific justification of the drivvel that is promoted and so far I have found that Prof Ian Mcdonald is paid by Mars and Coca cola, and that you have already pointed out the flimsyness of this Tedstone woman.
So, I wondered about going to this conference and inviting others to attend too, and to ensure that no one in that audience leaves without realising that the speakers are tricksters.
It is going to be held on Thursday 27 March 2014 at the Royal Soc Med at 1 Wimpole St. Here is a link to the event: http://www.rsm.ac.uk/academ/fhe02.php?utm_source=SilverpopMailing&utm_medium=email&utm_campaign=Food%20and%20health%20forum%20-%20Dietary%20-%20past%20dels%20(1)&utm_content=
I will be going, I will pay for my own ticket, and I suggest that everyone reading this comment turns up too.
I did do this last year when cereal grains were being promoted. I was challenging enough that all attendees realised that there is not one opinion and indeed grains are responsible for a lot of serious ill health! One of the speakers totally agreed with me!!
Anyway, there it is, I hope you come too and we can do some more good.
All the best ~ Afifah
Hi Afifah – I’ve put it in my diary and will see if it’s possible to attend. There’s a chance I may be in Scotland that week. Doesn’t it look like you’ll spend the whole of the day banging your head on the chair in front?!
Good find anyway – I’ll tweet it and let the club know – bit pricey though eh?
Very best wishes – Zoe

Hi Dan – you and me both! Studies like this don’t seem to know ‘good’ meat from bad. The real foodie definition of good meat is any unadulterated cuts from grass grazed animals – whether offal, chops, steak, whatever – it’s the life of the animal that matters.
In studies such as this one they tend to take any plain meat (beef, pork, lamb – which I assume to include plain cold cuts/offal) and call this unprocessed. Even if it’s chicken that has never seen daylight or ruminants that have been stuffed with grains that they can’t digest – they assume this meat to be unprocessed. They will consider burgers, sausages, packaged meats with dextrose/preservatives etc to be processed meats.
Hope this helps!
I’m having a hard time differentiating between processed meat and red meat. You mention red meat is beef, pork, or lamb. What would be processed meat? Would that be cold cuts? Anything else? And what would be offal?
Just wanted to stick up for “processed meat.”
Let’s not judge cuisine by risk percentages. Esp. not guesstimated risk percentages.
France Italy Spain etc have 2000 of glorious sausage making tradition. This wonderful world of amazing variety (European sausages) on the one side, versus +/- 0.06437 (~42.03 >**) etc on the other side.
Let’s vote for the sausage!
To be sure of my iron intake, I will continue to munch on a steak or much loved liver & bacon thank you. Fortunately I have years ago dumped the falsely vitamin/iron loaded and manufactured breakfast cereal from Mr Kellogs and his friends!
It’s quite appalling what the populous if fed as the real true info on food!
Unfortunately like politics, religion, conflict and so many other aspect of life.
I seem to remember a year or so ago hearing a report from the continent where (I think it may have been Italy) “processed meat” (not red) was linked to bowel cancer! So this is not new info but a re-run of old info with a Christmastime Santa Red twist!
Yes folks it must be Christmas time – not much news to report so must dish up a re-run!
Seen any good films lately on the good old telly – that are not re-runs!!
Maybe I am just becoming septic or even a sceptic!!!
Best wishes for a marvellous and healthy 2012 form Rob & Gerri xx
Unfortunately, I can’t be there, although I’d love to be – it looks like a great line up. I hope it all goes well. Hopefully I’ll make it to the next one….
Hi Brian – thanks so much for your lovely comment – and for the notes on the milk blog. I need to update that one – it should be try raw milk first, then other animals’ milk, then – as you say – the rice/almond options – almonds being even more natural than rice. The soy is the one to totally avoid and the WAFP (http://www.westonaprice.org/) information on soy is excellent – soy alert for others who haven’t discovered WAPF yet.
Are you coming to the conference in London Sat 26th March?
Very best wishes – Zoe
Zoe, thanks for driving a stake through this particular pork-pie. As usual, partial news reporting and bad science conspire to keep us all in the dark. Glad to see someone dissecting this nonsense so thoroughly.
Having recently become interested in the work of the Weston A. Price Foundation, Nina Planck, Paul Chek and others, I’ve been looking for someone based in the UK who’s an authority on “real food”.
I think I’ve just found you!
It’s not the red meat, maybe not even the processed meat that will kill one. It’s the blatant manipulation of facts, selective interpretation of scientific data, and feeding of bull to the public that sticks in one’s craw, which is “probably” more likely to cause one to choke and die – rather than any colorectal cancer or iron-deficiency risk! This kind of hysterical reporting is beyond wicked, and makes me wonder whether the journalists reporting on it are either on a sugar rush, or have lost all their objective, investigative faculties, or are on someone’s payroll. Thanks Zoe – keep exposing the insidious health rot, and vested interests, so often found hiding behind science! Makes me ashamed [at times] to be a health professional.

Thank you, oh thank you Zoe! I heard the TV headlines (and switched off) – read the newspaper headlines (and walked right past the newspaper stands) – because I knew it had to be utter rubbish. Now you have confirmed it. Liver, bacon and kidneys for dinner tomorrow night! :-)
