Busted: Cholesterol Claims

Cholesterol Claims Confound
Cholesterol-battling plant stanol-based Benecol has been busted in the UK for exaggerating TV advert claims even though they were based on UK National Health Service, British Heart Foundation (BHF) and World Health Organization (WHO) data.
A veteran healthy foods consultant called the ruling “stupid” and advised Raiso-owned Benecol’s UK license holder, Johnson & Johnson, to sue the UK agency in question.
The ads for Benecol drinking yoghurt claimed, "two out of three adults have high cholesterol" in the UK, but the Advertising Standards Authority (ASA) said the claim manipulated BHF and other data and,therefore exaggerated the health benefit of the product.”
‘Stupid?’
Despite being approved by the broadcast approver, Clearcast, the ASA also ruled the ad had inappropriately used an EU-approved cholesterol reducing claim by stating Benecol was, “proven to lower cholesterol by up to 10% in just three weeks."
“This attack on a European Food Safety Authority (EFSA)-approved claim has to be one of the most stupid regulatory rulings that I have seen,” opined industry consultant, editor and analyst Julian Mellentin.
The ASA panel who arrived at this decision must be composed of people with zero understanding of the regulation and the science. They should be called to account.”
ASA reasoning
The ASA said the Benecol ad had not been clear enough about what cholesterol levels of 5 mmol/l meant, even if WHO figures showed two thirds of people had raised cholesterol based on this measure. BHF data was similar.
In casting the ad as “misleading” and “exaggerated”, the ASA said some of the data was based on LDL cholesterol and not total cholesterol, and that some dated from five or more years ago.
Further, “While we acknowledged that the NHS Choices article submitted stated that total cholesterol of less than 5 mmol/l was advised for healthy adults, we noted that it did not state that all levels of over 5 mmol/l were considered to be ‘high’, rather than, for example, being considered raised or of moderate risk.”
“In addition, we were concerned that the BHF 2007 report gave blood cholesterol levels for England but that it did not include a UK figure.”
For the claim itself the ASA noted the European Commission backed claim wording flexibility but in this case was, “concerned that although the ad stated ‘LOWER CHOLESTEROL UP TO 10% in 3 weeks’, and ‘PROVEN TO LOWER CHOLESTEROL’, it did not include the required information about high cholesterol being a risk factor in the development of CHD [coronary heart disease].”
“We therefore considered the meaning of the authorised disease risk reduction claim was significantly altered.”
It said the supplementary information was not prominent enough in the ad compared to other information and concluded, “The ad must not be broadcast again in its current form.”
Challenge?
But this logic failed to impress Mellentin.
“The regulator is once again ignoring the fact that a company is using a legally permitted claim, that the wording falls very clearly within the boundaries of what is permitted by the regulation and that the product and the claim have been supported by eminent independent bodies such as the British Heart Foundation and several others.”
“It's time that companies resisted this type of ignorance and regulatory arrogance. If Benecol was my company I'd take the ASA to court where they would be subjected to a humiliation that they richly deserve.”
Benecol cholesterol-lowering claims were approved in many countries before the 2009 EU nutrition and health claim approvals that also included related plant stanols compounds.
That stated: The Panel concludes that for an intake of 1.5 - 2.4 g/d an average reduction of between 7 and 10.5 % can be expected.”

PUFAS Lead to Increased Inflammation

"A high intake of polyunsaturated fat in the diet, ... may lead to inflammatory ... disease, ..."

Dating back to 2007 there have been a dozen posts here on problems with the plant sterol products glutting the market. The most common of these products is the margarine with the claim of reducing heart disease.

Some other data exists showing that these products lead to asthma. Asthma, heart disease and inflammatory bowel disease are all symptoms of reactive inflammation.

I don't count plant sterols or the products made from them as healthy, nor do I consider that the PUFAS (polyunsaturated fatty acids) to be health promoting, except when an actual imbalance exists.

Additionally, the fact that many of these oils are from genetically engineered sources raise even more health concerns.

As the story goes, when making margarine just cooking the oils a little longer gives you the tub...

Healthy fat link to bowel disease
A high intake of polyunsaturated fat in the diet, while good for the heart, may lead to inflammatory bowel disease, say researchers.

Experts believe a high intake of linoleic acid, found in foods like "healthy" margarines, may be implicated in a third of ulcerative colitis cases.

The researchers base their findings, due to be published in Gut, on food diaries from more than 200,000 people.

If the link proves to be causal, some people might want to modify their diet.

“ There is good biological plausibility of why linoleic acid can cause inflamation, and certainly Western diets are often excessive in this kind of fat ”
Dr Anton Emmanual Core

The researchers also found that a diet rich in another type of fat, omega 3 fatty acid found in oily fish such as salmon and herring, reduced the likelihood of developing ulcerative colitis by 77%.

Linoleic acid is a naturally occurring essential fatty acid, present in a variety of foods, including the oils of seeds and nuts, such as sunflower, safflower, soya, corn seeds or walnut oils.

The multinational team working on the EPIC (European Prospective Investigation into Cancer and Nutrition) study say there is a plausible biological mechanism that could explain why linoleic acid is linked with this bowel condition.

Cell membranes

Once in the body, linoleic acid is converted to arachidonic acid, which is a component of the cell membranes in the bowel.

Arachidonic acid can then be converted into various inflammatory chemicals, high levels of which have been found in the bowel tissue of patients with ulcerative colitis.

In all, 126 of the people in the study developed ulcerative colitis after an average period of four years.

After adjusting for other factors likely to influence the results, including smoking, age, total energy intake, and use of aspirin, those whose diets included the most linoleic acid were more than twice as likely to develop the condition as those whose diets contained the least.

Lead researcher Dr Andrew Hart of the University of East Anglia, Norwich, said: "There are no dietary modifications of benefit in patients with ulcerative colitis, although, based on this study's findings, a diet low in linoleic acid may merit investigation."

In the UK, people consume on average about 10g per day of linoleic acid, found in around nine level teaspoons of polyunsaturated margarine or three teaspoons of sunflower oil.

In the study, the people who consumed the most linoleic acid had a daily intake three times this or more.

Biologically plausible

Dr Anton Emmanual, medical director of the digestive disorders charity Core, stressed that the study did not prove that linoleic acid caused bowel disorders, and warned that dietary diaries could be unreliable.

However, he said: "Nevertheless there is good biological plausibility of why linoleic acid can cause inflamation, and certainly Western diets are often excessive in this kind of fat.

"The omega 3 fish oils counteract the harmful effects of lineloic acid it would be helpful to see whether diets high in fish oils reduce colitis.

"Lineloic acid may have small part to play in some patients, but factors such as smoking, bacteria and stress are likely to be at least as important."

Professor Jon Rhodes, of the British Society of Gastroenterology, said the study was interesting, but also stressed it did not prove cause and effect - further tightly controlled studies would be needed to do that.

Dr Elisabeth Weichselbaum, of the British Nutrition Foundation, said the study was interesting.

But added: "The results need to be interpreted with caution.

"People who have very high intakes of omega-6 fats are likely to have a generally different diet from those with low intakes. Therefore, it may as well be possible that there are other factors that could have an effect."

Canola Comments

This update comes via my "Southern Comrade" and fellow health nut. I was throwing words around in my brain about a title for one of his posts. It had to be cleaver because we have this on-upsmanship thing going on.

I thought about a fellow I used to work with 30 years ago who is now a PhD and head of his village corporation in Alaska. He and I share another acquaintance who is an amazing artist and Puffin fan.

Not that any of this makes sense, it all comes back to play on words, so here is a link to more on fat, and 'Puffin PUFAS'.
Canola oil is a too commonly used ingredient in food, especially now that "plant sterols" are plugged into all kinds of things like margarine, vitamins, even aspirin. You'll find it in dog food and even in an ever increasing number of items in the natural food market place.

My suggestion is that you read this following definition of canola oil, understand it is toxic to the liver, it is a trans fat as a result of processing, and consider keeping out of your diet.
"Canola Oil contains 5% saturated fat, 57% oleic acid, 23% omega-6 and 10%-15% omega-3.

This oil was developed from the rape seed, a member of the mustard family. Rape seed is unsuited to human consumption because it contains a very-long-chain fatty acid called erucic acid, which under some circumstances is associated with fibrotic heart lesions. Canola oil was bred to contain little if any erucic acid and has drawn the attention of nutritionists because of its high oleic acid content.

But there are some indications that canola oil presents dangers of its own. It has a high sulphur content and goes rancid easily. Baked goods made with canola oil develop mold very quickly. During the deodorizing process, the omega-3 fatty acids of processed canola oil are transformed into trans fatty acids, similar to those in margarine and possibly more dangerous.

A recent study indicates that "heart healthy" canola oil actually creates a deficiency of vitamin E, a vitamin required for a healthy cardiovascular system. Other studies indicate that even low-erucic-acid canola oil causes heart lesions, particularly when the diet is low in saturated fat."

Not Balanced

I was visiting a friend recently and happen to notice two tubs of that margarine on her counter claiming to reduce cholesterol.

I've spoken against the use of these plant sterol products in classes I teach, in articles I've written, and in posts here at Natural Health News.

I always advise the use of unsalted butter (organic or BST free when ever possible) blended with high quality olive oil not sold in plastic.

Additionally I suggest the use of coconut oil.

The plant sterol mania coupled with the mis-information about cholesterol leaves out mention of the negative nutrition associated with the two oils relied on as some sort of miracle cure.

This morning a blog visitor mentioned a site that has some information that supports my theory on the use of canola and soy oil.

I am particularly moved by the supporting data this site offers, and here is a quote -

From The Journal of Nutrition. "Being a scientific journal it is a little difficult to read, but in summary, the content states that feeding two generations of rats with Canola oil as opposed to Soybean oil actually reduced the lifespan of the second generation of rats by about 20%! It also reduced the lifespan of the first generation, but by a smaller amount.

Erucic acid is the toxic component of Canola Oil, and the Australian Governement's website has the following very interesting article about the negative effects of erucic acid: http://www.foodstandards.gov.au/_srcfiles/Erucic acid monograph.pdf. In summary, the researchers found that just one dose of erucic acid was enough to cause the buildup of fatty deposits in the heart muscles of rats!

For access to more information

Here's hoping you do more investigation and learn what I've been trying to educate people about for a good decade or longer.

And move on past those tubs of chemicals and any thing else you find that contains "plant sterols". They just aren't for your best health.

The recipe I've used since I owned a first edition of "Laurel's Kitchen" is simply one half cup high quality extra virgin olive oil not sold in plastic and 1 stick of organic or BST free unsalted butter. Soften the butter and blend in the olive oil.

and VOILA - now you have your own "spread". And this one promotes health! Keep refrigerated but know that it is always spreadable.

Laurel's recipe has a few added ingredients but I dropped those years ago. If you like a little salt please use ONLY farmed Celtic salt or Tao salt. That trendy pink salt just has too much fluoride for health.

UPDATE: A reader objected to my comment on Pink Salt. I chose not to publish her comment because it contained a commercial site link.

You may find out more about the fluoride in Pink Himalayan salt here -
http://naturalhealthnews.blogspot.com/2008/01/salt-may-be-health-scam.html
and I will remind readers that farmed salt is not a product that contains excessive amounts of this dangerous element. Fluoride IS cumulative and it damages the pineal gland, other organs, teeth, bone, and body function, no matter the source.

A downside to using "plant sterols"

UPDATE: 12.08: A leading expert in the science of fats and oils, along with some researchers at Harvard, report that cholesterol-cutting spreads cause heart disease.

Ads for these so-called butter substitutes proclaim they promote heart health. But they are made from the world's deadliest fats! According to the Harvard study, consuming just 2 to 3 grams daily—the amount found in 3 to 6 cookies—increases the risk of heart disease by a whopping 21%!

Plant Sterols reduce concentrations of carotenoids
The Netherlands—An observed reduction in serum carotenoid concentrations during 18 months of consumption, according to a study published in the British Journal of Clinical Nutrition.

Natural Health News has several posts regarding the push on products containing "plant sterols", including aspirin, vitamins, and a variety of drinks for cholesterol lowering.

Our argument against these products is that they generally contain genetically modified (GMO) corn and soy oils.

The GMO ingredients alone is certainly risky enough, but soy and corn oils pose many other problems, such as the amount of herbicides and other chemicals used in the Big Ag approach to growing food.

Now it is found that the use of these products have a deleterious effect on the amount of the important anti-oxidant carotenoids (think yellow-orange-red foods and the vitamin A family) available (physiologically) for your health.

So my guess is that Promise and the rest of those brands hawking "plant sterol functional foods" better go back to the drawing table.
Functional foods enriched with plant sterol or stanol esters may lower serum concentrations of fat-soluble carotenoids.

The double blind, placebo-controlled human intervention trial lasted 18 months, and cross referenced to concentrations of lutein and zeaxanthin (carotenoids).

Forty-seven subjects were randomly assigned to one of the three treatment groups: margarine without added plant sterols or stanols, plant sterol-enriched margarine, or plant stanol-enriched margarine.

Changes in lipid-adjusted serum lutein/zeaxanthine concentrations between baseline and study end differed significantly between the three groups (P=0.001). No differences were found in the MPOD between the three treatment groups, despite the differences in both absolute and cholesterol-standardized serum lutein/zeaxanthine concentrations.
