Royal Society of Medicine
‘We know little about the effect of diet on health. That’s why so much is written about it’. That is the title of a post in which I advocate the view put by John Ioannidis that remarkably little is known about the health effects if individual nutrients. That ignorance has given rise to a vast industry selling advice that has little evidence to support it.
The 2016 Conference of the so-called "College of Medicine" had the title "Food, the Forgotten Medicine". This post gives some background information about some of the speakers at this event. I’m sorry it appears to be too ad hominem, but the only way to judge the meeting is via the track record of the speakers.
Quite a lot has been written here about the "College of Medicine". It is the direct successor of the Prince of Wales’ late, unlamented, Foundation for Integrated Health. But unlike the latter, its name is disguises its promotion of quackery. Originally it was going to be called the “College of Integrated Health”, but that wasn’t sufficently deceptive so the name was dropped.

The conference programme (download pdf) is a masterpiece of bait and switch. It is a mixture of very respectable people, and outright quacks. The former are invited to give legitimacy to the latter. The names may not be familiar to those who don’t follow the antics of the magic medicine community, so here is a bit of information about some of them.
The introduction to the meeting was by Michael Dixon and Catherine Zollman, both veterans of the Prince of Wales Foundation, and both devoted enthusiasts for magic medicne. Zollman even believes in the battiest of all forms of magic medicine, homeopathy (download pdf), for which she totally misrepresents the evidence. Zollman works now at the Penny Brohn centre in Bristol. She’s also linked to the "Portland Centre for integrative medicine" which is run by Elizabeth Thompson, another advocate of homeopathy. It came into being after NHS Bristol shut down the Bristol Homeopathic Hospital, on the very good grounds that it doesn’t work.
Now, like most magic medicine it is privatised. The Penny Brohn shop will sell you a wide range of expensive and useless "supplements". For example, Biocare Antioxidant capsules at £37 for 90. Biocare make several unjustified claims for their benefits. Among other unnecessary ingredients, they contain a very small amount of green tea. That’s a favourite of "health food addicts", and it was the subject of a recent paper that contains one of the daftest statistical solecisms I’ve ever encountered
"To protect against type II errors, no corrections were applied for multiple comparisons".
If you don’t understand that, try this paper.
The results are almost certainly false positives, despite the fact that it appeared in Lancet Neurology. It’s yet another example of broken peer review.
It’s been know for decades now that “antioxidant” is no more than a marketing term, There is no evidence of benefit and large doses can be harmful. This obviously doesn’t worry the College of Medicine.
Margaret Rayman was the next speaker. She’s a real nutritionist. Mixing the real with the crackpots is a standard bait and switch tactic.
Eleni Tsiompanou, came next. She runs yet another private "wellness" clinic, which makes all the usual exaggerated claims. She seems to have an obsession with Hippocrates (hint: medicine has moved on since then). Dr Eleni’s Joy Biscuits may or may not taste good, but their health-giving properties are make-believe.
Andrew Weil, from the University of Arizona
gave the keynote address. He’s described as "one of the world’s leading authorities on Nutrition and Health". That description alone is sufficient to show the fantasy land in which the College of Medicine exists. He’s a typical supplement salesman, presumably very rich. There is no excuse for not knowing about him. It was 1988 when Arnold Relman (who was editor of the New England Journal of Medicine) wrote A Trip to Stonesville: Some Notes on Andrew Weil, M.D..
“Like so many of the other gurus of alternative medicine, Weil is not bothered by logical contradictions in his argument, or encumbered by a need to search for objective evidence.”
This blog has mentioned his more recent activities, many times.
Alex Richardson, of Oxford Food and Behaviour Research (a charity, not part of the university) is an enthusiast for omega-3, a favourite of the supplement industry, She has published several papers that show little evidence of effectiveness. That looks entirely honest. On the other hand, their News section contains many links to the notorious supplement industry lobby site, Nutraingredients, one of the least reliable sources of information on the web (I get their newsletter, a constant source of hilarity and raised eyebrows). I find this worrying for someone who claims to be evidence-based. I’m told that her charity is funded largely by the supplement industry (though I can’t find any mention of that on the web site).
Stephen Devries was a new name to me. You can infer what he’s like from the fact that he has been endorsed byt Andrew Weil, and that his address is "Institute for Integrative Cardiology" ("Integrative" is the latest euphemism for quackery). Never trust any talk with a title that contains "The truth about". His was called "The scientific truth about fats and sugars," In a video, he claims that diet has been shown to reduce heart disease by 70%. which gives you a good idea of his ability to assess evidence. But the claim doubtless helps to sell his books.
Prof Tim Spector, of Kings College London, was next. As far as I know he’s a perfectly respectable scientist, albeit one with books to sell, But his talk is now online, and it was a bit like a born-again microbiome enthusiast. He seemed to be too impressed by the PREDIMED study, despite it’s statistical unsoundness, which was pointed out by Ioannidis. Little evidence was presented, though at least he was more sensible than the audience about the uselessness of multivitamin tablets.
Simon Mills talked on “Herbs and spices. Using Mother Nature’s pharmacy to maintain health and cure illness”. He’s a herbalist who has featured here many times. I can recommend especially his video about Hot and Cold herbs as a superb example of fantasy science.
Annie Anderson, is Professor of Public Health Nutrition and
Founder of the Scottish Cancer Prevention Network. She’s a respectable nutritionist and public health person, albeit with their customary disregard of problems of causality.
Patrick Holden is chair of the Sustainable Food Trust. He promotes "organic farming". Much though I dislike the cruelty of factory farms, the "organic" industry is largely a way of making food more expensive with no health benefits.
The Michael Pittilo 2016 Student Essay Prize was awarded after lunch. Pittilo has featured frequently on this blog as a result of his execrable promotion of quackery -see, in particular, A very bad report: gamma minus for the vice-chancellor.
Nutritional advice for patients with cancer. This discussion involved three people.
Professor Robert Thomas, Consultant Oncologist, Addenbrookes and Bedford Hospitals, Dr Clare Shaw, Consultant Dietitian, Royal Marsden Hospital and Dr Catherine Zollman, GP and Clinical Lead, Penny Brohn UK.
Robert Thomas came to my attention when I noticed that he, as a regular cancer consultant had spoken at a meeting of the quack charity, “YestoLife”. When I saw he was scheduled tp speak at another quack conference. After I’d written to him to point out the track records of some of the people at the meeting, he withdrew from one of them. See The exploitation of cancer patients is wicked. Carrot juice for lunch, then die destitute. The influence seems to have been temporary though. He continues to lend respectability to many dodgy meetings. He edits the Cancernet web site. This site lends credence to bizarre treatments like homeopathy and crystal healing. It used to sell hair mineral analysis, a well-known phony diagnostic method the main purpose of which is to sell you expensive “supplements”. They still sell the “Cancer Risk Nutritional Profile”. for £295.00, despite the fact that it provides no proven benefits.
Robert Thomas designed a food "supplement", Pomi-T: capsules that contain Pomegranate, Green tea, Broccoli and Curcumin. Oddly, he seems still to subscribe to the antioxidant myth. Even the supplement industry admits that that’s a lost cause, but that doesn’t stop its use in marketing. The one randomised trial of these pills for prostate cancer was inconclusive. Prostate Cancer UK says "We would not encourage any man with prostate cancer to start taking Pomi-T food supplements on the basis of this research". Nevertheless it’s promoted on Cancernet.co.uk and widely sold. The Pomi-T site boasts about the (inconclusive) trial, but says "Pomi-T® is not a medicinal product".
There was a cookery demonstration by Dale Pinnock "The medicinal chef" The programme does not tell us whether he made is signature dish "the Famous Flu Fighting Soup". Needless to say, there isn’t the slightest reason to believe that his soup has the slightest effect on flu.
In summary, the whole meeting was devoted to exaggerating vastly the effect of particular foods. It also acted as advertising for people with something to sell. Much of it was outright quackery, with a leavening of more respectable people, a standard part of the bait-and-switch methods used by all quacks in their attempts to make themselves sound respectable. I find it impossible to tell how much the participants actually believe what they say, and how much it’s a simple commercial drive.
The thing that really worries me is why someone like Phil Hammond supports this sort of thing by chairing their meetings (as he did for the "College of Medicine’s" direct predecessor, the Prince’s Foundation for Integrated Health. His defence of the NHS has made him something of a hero to me. He assured me that he’d asked people to stick to evidence. In that he clearly failed. I guess they must pay well.
Herbal medicine is, unlike homeopathy, not ridiculous, It is merely Pharmacology, as practised up to circa 1900. Whereas good trials have now shown acupuncture to be sham and homeopathy to be a placebo, there has been very little good research on herbs.
Most herbalism could fairly be described giving to sick patients an unknown dose of a substance with unknown efficacy and unknown safety.
How odd, then, to visit the Royal Society of Medicine to be greeted thus.
Just look at the words!
“Traditional Chinese Medicine (TCM) has developed over thousands of years”
That’s partly true
“and provides a comprehensive and systematic understanding of the natural world and the treatment of the human body.”
and that is total nonsense. TCM provides no understanding and virtually none of it is known to be useful for treating anything.
|Another poster at the RSM exhibition provides some of the explanation.
What on earth, one wonders, do they mean by “making efforts to modernise TCM “? So far, the idea of modernising TCM doesn’t seem to include any great effort to find out if it works.
Much of the promotion of TCM seems to be not so much ‘ancient wisdom’, but modern nationalist propaganda by the Chinese government.
The history is fascinating, but you won’t learn it from the posters on display at the exhibition.
“The Daoguang emperor though it [acupuncture] was a barrier to medical progress and removed it from the curriculum of the Imperial Medical Institute,”
“By the start of the twentieth century, acupuncture was extinct in the West and dormant in the East. It might have fallen out of favour permanently, but it suddenly experienced a revival in 1949 as a direct result of the communist revolution and the establishment of the People’s Republic of China. Chairman Mao Tse-tung engineered a resurgence in traditional Chinese medicine, which included not just acupuncture but also Chinese herbal medicine and other therapies ”
“His motivation was partly ideological, inasmuch as he wanted to reinforce a sense of national pride in Chinese medicine. However he was also driven by necessity. He had promised to deliver affordable healthcare .. . . ”
“Mao did not care whether traditional Chinese medicine worked, as long as he could keep the masses contented. In fact, his personal physician, Zhisui Li, wrote a memoir entitled ‘The Private Life of Chairman Mao’, in which he quoted Mao as saying”
“Even though I believe we should promote Chinese medicine, I personally do not believe in it. I don’t take Chinese medicine.” “Singh & Ernst Trick or Treatmant, page 46.
Or, as put more succinctly by Shapiro
“You would never know that TCM was fashioned in the twentieth century, as we shall see, from a ragbag of therapies in post-revolutionary China.”
Why is the Royal Society of Medicine allowing such mendacious posters? As it happens, I and a friend were visiting the RSM to see their Academic Dean, with a view to finding out why the RSM had failed to take any public position on alternative medicine. The answer appeared to be money, and that was the answer to why the TCM exhibition was being held on their premises too. The Dean no more believed in TCM than we did, but, well, they need the income. He pointed out (looking suitably sheepish) that the address given for the exhibition was not the RSM, but Number 1 Wimpole Street (that, of course, is also the address of the RSM).
Ah, so that’s OK then.
It has to be said that the RSM isn’t alone in its spineless attitude. Both the British Medical Association (BMA) and the Royal College of General Practitioners (RCGP) have failed to make any clear condemnation of mystical medicine. This is in stark contrast to just about every relevant scientific society (here is a summary).
It is a mystery to me why much of medicine should still be dominated by a mindset that seems to have lagged 200 years behind every other science. Perhaps medicine is just too complicated.
UCL Hospitals’ skeleton in the cupboard
Make no mistake, University College London Hospital is top class. The UCLH Trust. runs seven hospitals All but one of them are excellent. But in 2002 the Royal London Homeopathic Hospital was acquired as part of the UCLH group, to the intense embarrassment of UCL scientists.
Let’s start with the good bit. Usually I don’t like anecdotes, so just think of this as a vote of thanks, not evidence.
A personal history of UCH
I owe UCLH a lot personally. On December 13th 1984, my wife had
a subarachnoid haemorrhage when she was seven months pregnant. After misdiagnosis at St Peter’s Hospital, Chertsey, she was moved to UCH and diagnosed very quickly. The next day she had neurosurgery to pin an aneurysm at the Maida Vale Neurosurgical Hospital, part of the UCLH group (it no longer exists). The surgeon, Alan Crockard, came out of theatre after five hours, looking rather tired and said “it was adhered to the optic chiasma on one side and about a millilmetre from the pituitary on the other. It was a bit tricky but I think we got it”.
|After a week in intensive care, under heavy sedation, Margaret’s blood pressure was not low enough and they decided to deliver the baby. At about 4 pm on a snowy Christmas Eve, a team of neurosurgeons and a team of obstetricians gathered and soon after, Andrew Stuart Colquhoun emerged in a small incubator to be whisked off in an ambulance to the Special Care Baby Unit at UCH (run, at that time, by Osmund Reynolds).. Christmas day was spent in the hospital, with Margaret’s mother. Andrew weighed 1.4 kg at birth, but by Christmas day he had pulled out his ventilator himself, and was doing fine. He was so tiny that it was a couple of days before I dared to hold him. The Unit had racks of doll-sized clothes, knitted by volunteers.||

Once Margaret was well enough, she was given a side room in a neurosurgical ward with a cot for Andrew by her bed, an arrangement that gave the neurosurgical nurses some fun. They were in UCLH continuously until 27th April before Margaret had recovered enough to go home, [Full photo album here]
Now they are both fine.and Andrew is 6′ 7″ (200.5 cm)..
It is episodes like this that make one very proud of the NHS. Heaven knows what it would have cost in the USA.

But now the the less desirable side of UCLH
Herbs and homeopaths at UCLH
|Recently I was sent the UCLH Annual Review 2007 – 2008. There was a lot of good stuff in it and worth a read despite there being too much hyperbole and too many pictures of men in dark suits. But buried among all the high tech stuff, what do we find but an advertisement for 1900-style pharmacology in the form of the herbal clinic at the Royal London Homeopathic Hospital, accompanied by a load of utterly inaccurate information from the TV botanist, David Bellamy.
Take, for example, the claim about Devil’s Claw for osteoarthritis. Even alternative medicine advocates said “The authors concluded that there are insufficient high-quality trials to determine the safety and efficacy of Devil’s Claw (Harpagophytum procumbens) in the treatment of osteoarthritis, and that definitive trials are needed.”
Reading between the lines, I’d guess that the opening of this clinic has a subtext. It is well known that funding for homeopathy has dried up (partly as a result of our letter to NHS Trusts that appeared in the
There have been problems before with the herbal activities at the RLHH before (see Conflicts of Interest at the Homeopathic Hospital). It appeared that the Khans, who run the Marigold homeopathic podiatry clinic (no, seriously, it is real) were largely prescribing a herbal product that was made by their own company. without even the hospital trust, never mind the patients, being made aware of it. In normal medicine this would be regarded as a rather serious offence, but as far as I know, nothing was ever done about it.
The ethics of alternative medicine are truly one of life’s great mysteries.
Reading further in the annual review, we come to the page about the RLHH. The homeopathy side must really have run down because it seems to have diversified into selling cosmetics and groceries. That sounds like desperation.
Good heavens, they sell “chemical-free sun cream”. One wonders what it can be made of, if not chemicals. This is the language of low-grade advertising agencies, not what one expects from an NHS hospital trust.
|But next to this there is a much more interesting item. Just look at the last sentence.
I wonder if this could possibly have anything to do with the fact that Michael Baum and I visited the Trust headquarters in August 2006 to propose that the RLHH might be turned into a centre of supportive and palliative care?
It would be nice to think so. But it seems they haven’t gone nearly far enough yet. If all they do is replace the waning homeopathy
We know they are under pressure from their royal patrons, but that, in a constitutional monarchy, is simply not acceptable.
Michael Baum is a cancer surgeon who has taken a particular interest in palliative and supportive care. He is someone whose views should be taken seriously. He is also the author of the magnificent “An open letter to the Prince of Wales: with respect, your highness, you’ve got it wrong” Here is a quotation from that letter. The UCLH Trust should bear it in mind.
|The power of my authority comes with a knowledge built on 40 years of study and 25 years of active involvement in cancer research. I’m sensitive to the danger of abusing this power and, as a last resort, I know that the General Medical Council (GMC) is watching over my shoulder to ensure I respect a code of conduct with a duty of care that respects patients’ dignity and privacy and reminds me that my personal beliefs should not prejudice my advice.
Your power and authority rest on an accident of birth. Furthermore, your public utterances are worthy of four pages, whereas, if lucky, I might warrant one. I don’t begrudge you that authority and we probably share many opinions about art and architecture, but I do beg you to exercise your power with extreme caution when advising patients with life threatening diseases to embrace unproven therapies. There is no equivalent of the GMC for the monarchy, so it is left either to sensational journalism or, more rarely, to the quiet voice of loyal subjects such as myself to warn you that you may have overstepped the mark. It is in the nature of your world to be surrounded by sycophants (including members of the medical establishment hungry for their mention in the Queen’s birthday honours list) who constantly reinforce what they assume are your prejudices. Sir, they patronise you! Allow me this chastisement.
