Earlier this week, someone sent me a link this article that reports on a recent decision made by the Advertising Standards Authority in the UK regarding two television adverts for the cholesterol-reducing margarine Flora pr.activ.
The television adverts included text and a voiceover informing us that: “No other food lowers cholesterol more”. Two people complained about this, questioning whether this claim was substantiated. In their defence, the people at Flora claimed they had not implied that the product was better at lowering cholesterol than any other food, only that no other food could lower cholesterol more. I’m not sure I quite understand the difference, and it anyhow, the ASA decreed this was a claim to far and subsequently ordered that the adverts should not be broadcast again. You can read the whole adjudication at the ASA website here.
The ASA also took exception to the fact that in neither advert contained the ‘permitted’ claim (according to European regulations) that: “high cholesterol is a risk factor in the development of coronary heart disease”. The Flora people claimed that this was superfluous, because it’s a commonly understood point, and I actually have some sympathy for their position: my experience is that the vast majority of people associate ‘raised cholesterol’ with an increased risk of heart disease.
None of this matters much in my opinion, though, because I think the ASA’s issues with the adverts fail to strike at the heart of the issue. If Unilever (the company that manufactures Flora) was to play by the rules then it could claim that raised cholesterol is a risk factor for heart disease, and that its product reduces cholesterol. What the public will generally take from this is the idea that ‘Flora reduces risk of heart disease’.
Leaving individuals with this impression would be fine if there was any evidence for it. In reality, though, there isn’t. Even if raised cholesterol causes heart disease (I have my doubts about it being as straightforward as this), the fact that something reduced cholesterol does not assure it reduces the risk of heart disease. For example, we have plenty of examples of drugs that have been effective for ‘improving’ cholesterol levelsbut have not reduced and sometimes have even increased heart disease risk.
For the idea that Flora pro.activ is good for heart health to be valid requires us to have studies that show these foodstuffs actually reduce the risk of heart disease. Not one single such study exists in the scientific literature.
But there’s even worse news to come for those who have been taken in by the slick marketing of the cholesterol theory and ‘remedies’ for ‘raised’ cholesterol in the form of foodstuffs enriched with ‘plant sterols’ (like Flora pro.activ) that lower cholesterol by inhibiting its absorption from the gut.
Sterols in food can also make their way from the gut into the bloodstream, and several studies link higher levels of sterols here with enhanced risk of cardiovascular disease [1-6]. This evidence is epidemiological in nature, which means we cannot conclude from it that sterols actually increase the risk of cardiovascular disease (only that the two are associated). However, more incriminating evidence comes of studies in which the effects of sterols have been tested on tissues or animals in the lab, and been found to have adverse effects. You can read an account of some of this evidence in a recent blog post here.
The issue with the Flora adverts, in my opinion, does not relate to claims about their cholesterol-lowering properties. I think the real crime is that there is no evidence that these foodstuffs do any good, and at least some evidence exists that suggests they have genuine potential for harm.

The provenance in past affairs involving the Advertising Standards Authority (ASA) and Unilver as the owners of the brand Flora indicates that complaints brought by concerned consumers rarely get upheld by the ASA. The porcess of delivering a complaint is not at consumer centric.
Some individuals with distinguished insights have tried to make very justified complaints against the claims residing in the advertising of Flora and their complaints have not been upheld. Craig Sams, who co-founded Green and Blacks, who is strong advocate of free trade and a significant proponent of organic practice in agriculture comes to mind as one who pressed forwards a complaint that was not upheld. And the late Barry Groves, the author of ‘Truck and Treat’, the foremost book and thesis that has done so much to indicate grounds for concern against the overconsupmtion of refined and easily digestible carbohydrates in combination with overconsumption of polyunsaturated fats (PUFAs), is another informed complainant whose complaint was likely well constructed and entirely justified.
The great difficulty, as Barry confered in conversation, is that the ASA does not perceive its prupose should involve breaking ranks with associated agencies. They’ll take the advice of the alternate agencies it may have cause to consult as read. This perception dictates that at times the ASA is actually unfit for purpose. Officers and a team at Scotland have demonstrated the potential gains to be had from a back to basics approach in which no propostion or piece of evidence is taken for granted.
Enlightened people could argue, quite rightly, that the FSAs former ‘mutton fat blocks the kitchen wastepipe’ campaign aimed at propagating conscern for consumption of saturated fat and its alleged (and unsubstantiated) involvemnent as a leading cause of heart disease would breach the Advertsising Standards Code of Pratice for having absolotely no basis in fact and being a poor representation of the fiction, even(!). But it would nver do for the ASA to to ignore the advice of the agency (the FSA) whom it would have consulted at the time.
Anyway, the ruling is a knockback of sorts for Unilever, the makers of Flora, and even though the ruling does not script good sense into the case history of compliants, it is progress ois sorts.
I know for certain and without any doubt, that coconut oil, olive oil, eating oily fish and lots of eggs and butter will bring your cholesterol did. It did so with me – it’s recorded by Lancet. Before I used to eat tubs of the “best” kinds of margarines (flora mostly) and my numbers would soar dramatically whenever I lowered my dosages of lipid lowering drugs. What they purport in their advertisement is an outright lie.
Spot on
By now I consider Unilever to be a criminal organization. They know; it’s not the amount of cholesterol but the nature of the cholesterol that matters. But all they want is your money. Your health is your problem. I think they call it ‘marketing’, but I am not sure.
Margarine is poison even without the stereols. You know; too much omega 6 stimulates inflamation. The stereols only make it worse.
I am not a fan of conspiracy theories, but they all work together : government agencies, food industry and retailers. They all want a piece of the action. In the mean time we all get sick.
I don’t expect to see a change there. Only option you have is to educate yourself and act accordingly. Blogs like these – there are others – help. Dr Briffa is one of the good guys 😉
Quite apart from the criminal waste that the ‘low cholesterol’ industry inflicts on the NHS (more than 2bn and rising) and to our health, have you ever tasted these spreads? It’s a crime against our taste buds.
I have heard that ants will ignore Flora!
Is anyone else bothered by the increasing amounts of unfermented soy to be found in food, and animal food? It’s even in chocolate, which for me, makes it easy to avoid. Ditto bread flour, which we also avoid.
I used to suffer with regular migraines, but haven’t had a single one since adopting low carb approach. We don’t have colds, either.
