Cardiovascular disease (CVD) is a group of disorders involving the heart and blood vessels and is the leading cause of death globally1. CVD can result in heart attack, stroke and other serious conditions and more people die from CVDs than any other cause1.

As a health practitioner for over 22 years, I’ve been educating my clients all along that lowering cholesterol does not necessarily prevent mortality from cardiovascular disease and that vegetable oils (including those ‘special’ margarines that are marketed to reduce cholesterol levels) do nothing to reduce the number of deaths from heart attacks or strokes.

I’ve said from the start that a ‘low-fat diet’ per se does not prevent coronary heart disease and that it can be a major contributor to obesity and type II diabetes. In addition, I’ve always maintained that there are far more reliable tests for stroke and heart attack risk than simply ‘measuring cholesterol levels’.

It turns out that my claims have now been proven and they were all proven decades ago – but the research was hidden from the public.

Until now……

‘Study turns the traditional ‘diet-heart’ hypothesis on its head’

Consuming vegetable oils rich in linoleic acid lowers blood cholesterol but does not reduce mortality from heart disease, according to a study published in the BMJ. 

The US researchers analysed decades-old unpublished data from a double-blind randomised controlled trial of more than 9000 people which tested whether replacing saturated fats with vegetable oil (corn oil) reduced cardiovascular deaths through the lowering of blood cholesterol.

Participants in the intervention group did report lower cholesterol levels, but the researchers also found there was a 22% higher risk of death for each 30mg/dL reduction in serum cholesterol levels.

And members of the intervention group also did not have less atherosclerosis or fewer infarcts at autopsy compared with controls.

The researchers conducted a systematic review of four other trials but failed to find any reduction in death from coronary heart disease or other causes through replacing saturated fats with vegetable oils.

They say the collective findings from the trials “do not provide support for the central diet-heart tenet that the serum cholesterol lowering effects of replacing saturated fat with linoleic acid translate to reduced risks of coronary heart disease and death”.

The researchers say the new findings add to growing evidence that “incomplete publication has contributed to overestimation of the benefits of replacing saturated fat with vegetable oils rich in linoleic acid”.

They say it’s possible key results from the trial were not published at the time because they were “clearly at odds with prevailing beliefs”.

“It is interesting to speculate whether complete publication of randomised controlled trial results might have altered key policy decisions promoting replacement of saturated fat with linoleic-rich oils or contributed to a shift in research priorities,” the researchers write.

They suggest attention should now turn towards why high consumption of linoleic acids leads to higher mortality.
