Few columns in WDDTY reveal the hypocrisy of the SCAM industry quite so consistently as Rob Verkerk’s. Rob runs the Alliance for Natural Health Europe (ANH-Europe), a SCAM industry lobby group indistinguishable in function and purpose from the lobbying companies used by “big pharma”, but far less scrupulous when it comes to accuracy, because Rob (like many of his contemporaries) not only lobbies for SCAM, he also makes money from SCAM, and makes more money promoting in print the SCAM from which he makes money.
His February 2014 is perfect of its type:
Few Natural-health aficionados would have been unable to miss the media reports about vitamins being a waste of money. They hit every major newspaper, radio and TV station last December.
Yes, it’s a welcome change from the usual credulous nonsense planted by people like Rob Verkerk.
The Times’ science correspondent, Tom Whipple, the journalist that has had his crosshairs focused on this very magazine in separate articles appearing on the 1st October and 2nd November, was the most condemning.
No evidence that Tom Whipple was the most condemning, but to say he has his crosshairs focused on WDDTY is a classic appeal to motives: according to Verkerk, Whipple cannot be trusted because he has an agenda against WDDTY. In fact, the opposite is true: Whipple can be trusted precisely because he has spoken out against the misleading information in WDDTY, rather than either parroting it or ignoring it as most journalists do.
Rob Verkerk, like Lynne McTaggart and all the other contributors to WDDTY, is unable to separate objective scrutiny of false information from suppression of free speech. That’s because they sincerely believe things which are unsupported by scientific evidence, and that’s precisely why any trustworthy health journalist will give overwhelmingly negative coverage to WDDTY.
His piece, in the 17th December edition of the newspaper, declared, “Vitamin pills are a waste of money, experts warn.” The Daily Mail said multivitamins “do nothing to protect us from illness”.
And this is true: for most people eating a healthy balanced diet, supplements are unnecessary. And for those who are not eating a healthy balanced diet, a change of diet is vastly preferable to supplementation.
So who are those experts, and what did they actually reveal or say? The first thing to recognize is that the most damning headlines about vitamin and mineral supplements weren’t generated from any new clinical trials or even analyses of previous trials. They actually came from an opinion piece written as an editorial by a number of scientists and appearing in the same issue of the medical journal Annals of Internal Medicine (AIM) that also included three reviews of past studies. Some of the authors had been engaged in previous studies of high-dose synthetic vitamin supplements.
Apparently Rob Verkerk doesn’t understand the process of scientific consensus building. This article summarised several reviews and other evidence, and drew a conclusion. That’s what science does. It’s interesting, though, that a columnist in WDDTY would try to play the “appeal to authority fallacy” card to undermine a published paper – great swathes of WDDTY would be blank if the editors adopted the view that appeals to authority are not reliable.
But this was a serious, highly credible, well-researched article in a major peer-reviewed journal. That’s why it is so important, and why Verkerk has to spin like crazy to downplay it.
One review, the biggest by far, evaluated 26 studies to see if there was a link between taking typical dosages and forms of multivitamin/ mineral supplements and death from any cause, as well as death from either cancer or heart disease.
Another looked at two studies that evaluated the effects of a multivitamin on reducing cognitive decline in the elderly, and the third investigated whether a multivitamin could reduce cardiovascular events among those who’d already had a heart attack.
Indeed. And the results were underwhelming to say the least.
Any clinicians worth their salt and practising in the field of nutritional medicine, if asked to propose the likely outcomes of the multivitamin interventions evaluated by the three AIM articles, would have said “no chance”. And guess what? That’s just what was found. But this then gave the editorial authors a chance to blast their anti-supplement sentiments through an opinion piece that generated international news headlines.
A physician worth their salt and practising in the field of nutritional medicine, is called a dietician. It’s a protected title, and practitioners are subject to training requirements and statutory regulation. And yes, they would say that the chances of a positive result from precisely the kinds of routine supplementation that makes millions for the SCAM industry in product sales is slim. Multivitamins are, as the article says, probably a complete waste of money. How many shelves in your local pharmacy would that empty?
It’s big business. And the business needs its spin machine – including mouthpieces like Verkerk – to undermine a finding that is in the end neither surprising nor controversial.
The anti-supplement machine is rather well oiled and appears to be wheeled out every couple of years or so, presumably to try to dissuade people from doing too much to manage their own health. Short of banning supplements—something already happening especially within the EU and causing us to lose some of the most efficacious products, which threaten drug sales—this appears to be the favoured strategy among those with this particular agenda.
The pharma shill gambit rides again. What “anti-supplement machine”? When was the last time you saw an advertisement telling you not to buy supplements? When did you last see a campaign to stop shops selling supplements? Who is behind this “anti-supplement machine”? Certainly not “big pharma”, as they own many supplement brands. Whoever it is, they are doing a startlingly inept job: supplements are everywhere, touted by all kinds of credible-looking people using sciencey-sounding words, and they are getting away with it. Nearly a third of the UK population are popping supplements, and according to the evidence they are mainly worthless. That’s not evidence of a well-oiled anti-supplement machine is it?
The statement that this is “presumably to try to dissuade people from doing too much to manage their own health” is an appeal to motives; what Verkerk really means is that promotion of good science (i.e. science talking down the benefit of supplementation) is designed to dissuade people from giving unnecessary money to him, and others like him. The whole point of recent activity around regulatory changes is precisely that people are not managing their own health by taking supplements, they are mainly handing money to charlatans. Hence controls on maximum doses, to provide some control over vitamin megadoseW quacks.
What you don’t read in the papers is what was actually found in the studies. Did you read that a simple multivitamin can lower cancer risk in men by 8 per cent? You probably didn’t read that there were many studies that found positive effects. It’s just when you pool studies that have conflicting results, the very nature of a systematic review of this type, that you run the risk of cancelling out the variable results, even when they may have been due to other factors.
The whole point of a systematic review is that it balances the chance positive findings inevitable in clinical studies, and finds the overall effect to a much greater degree of certainty. As with homeopathy, the number of positive studies is completely irrelevant to the consensus of review studies that there is no credible evidence of effect. The positive studies are not ignored by systematic reviews, they are assessed, weighted according to methodological quality, and factored into the mix.
When the summary finding is no benefit, there’s no point howling about the positive results. The systematic review has already taken account of them. That is, after all, the point.
Also conspicuously absent from the news reports was any discussion of the reasons why most people take a daily multivitamin. They do so because of perceived benefits regarding things like energy levels, athletic performance, mental alertness and immune support.
Really? Where do they get this perception of benefit, given that the reviews find no actual benefit? Ah, wait: it’s a placebo effect caused by people like Verkerk talking up the clinically indefensible products from which he makes such a nice living.
In fact, many of these kinds of relationships have actually been proven scientifically, and have been officially authorized as health claims for use on commercial products EU-wide by the European Food Safety Authority (EFSA), the EU’s highest authority on food safety.And the EFSA is notoriously tough on accepting health claims. They’ve only approved about 250 in total, and most of these are for vitamins and minerals.
Not strictly true, since these approvals often rely on subjective assessments of benefit, but why would this be a problem? If the evidence is there, then the product is licensed and can be sold. If it’s not, then the evidence isn’t there. Verkerk appears to be arguing that because EFSA approves other products of this class, albeit not many, then all products of the class should be sold as if they were covered. Why would that be a good idea?
Another point made in the AIM editorial is that people can get everything they need from their diet.
Well, I agree. But only in theory, or in relation to a tiny section of society who are able to put in huge amounts of effort to source and prepare the best highest-quality foods and eat them consistently, day in, day out.
That is a fantastically implausible claim, and actually it’s the Nirvana fallacy. It is not hard to eat a balanced diet, and if it were then we’d scarcely have survived the harsh evolutionary realities of life. It doesn’t have to be the absolute best (either as defined by dieticians or quack nutritionists), it only has to be good enough.
The idea that a normal diet is substantially deficient in nutrients, is self-evidently bizarre. Vitamins were essentially unknown prior tot he late 18th Century and there is little doubt that the nutritional quality of our diet has improved vastly since then due to refrigeration and other techniques to prevent spoilage.
In practice, many of us fall dismally below optimal levels in one or more nutrients, and population-wide surveys show us that deficiencies in vitamin A (for immunity), vitamin K (for bone health), magnesium (for muscles and energy) and zinc (for immunity) are rampant. Worse than this, many of us carry genetic defects, referred to as ‘single nucleotide polymorphisms’ (SNPs), which mean we benefit from taking above average levels of particular nutrients to compensate. None of this gets a mention of course, despite the fact that this area of nutritional science— nutrigenomics—is one of the most rapidly expanding areas today.
This is a great argument for eating better and a truly terrible argument for buying a product which, according to the evidence, is routinely mis-sold by its proponents.
It seems that newspapers like The Times can only get away with creating headlines out of these issues if they are highly selective about the ‘facts’ and omit doing justice to the commonly accepted principles of standards of journalism and critical, unbiased reporting. I’m confident that most insightful readers will have been able to read past the agenda of the scientists and journalists involved.
You “forgot” to show that they were in the least bit selective. They didn’t toe the vitamin peddlers’ line, but that is a point in their favour rather than against them
Because doctors, unlike vitamin peddlers, care about your health, not their profits.
