From Dr. Mercola: Previously Missing Trial Data Confirms Harms of Too Much Omega-6
The myth that vegetable oils (rich in omega 6 fats) are healthier for you than saturated animal fats has been a tough one to dismantle. But the truth cannot be quenched forever. According to a BMJ press release:1
“Dietary advice about fats and the risk of heart disease is called into question on bmj.com today as a clinical trial shows that replacing saturated animal fats with omega-6 polyunsaturated vegetable fats is linked to an increased risk of death among patients with heart disease.”
The latest in-depth analysis of the health effects of omega-6 linoleic acid (LA) on coronary heart disease was not possible until now because data from the Sydney Diet Heart Study was missing.
This was a randomized controlled trial conducted from 1966 to 1973. Researchers from the US and Australia recovered the original data, and using modern statistical methods, they were now able to compare the death rates from cardiovascular disease, coronary heart disease, as well as all-cause mortality.2
“Their analysis involved 458 men aged 30-59 years who had recently had a coronary event, such as a heart attack or an episode of angina. Participants were randomly divided into two groups,” BMJ writes.
“The intervention group was instructed to reduce saturated fats (from animal fats, common margarines and shortenings) to less than 10 percent of energy intake and to increase linoleic acid (from safflower oil and safflower oil polyunsaturated margarine) to 15 percent of energy intake. Safflower oil is a concentrated source of omega-6 linoleic acid and provides no omega-3 PUFAs.”
The control group received no particular dietary advice and was allowed to eat whatever they wanted. Both groups kept food diaries for an average of 39 months. The results showed that:
The omega-6 linoleic acid group had a 17 percent higher risk of dying from heart disease during the study period, compared with 11 percent among the control group (those who did not receive any particular dietary advice)
The omega-6 group also had a higher risk of all-cause mortality
I’ve repeatedly stated it’s very important to maintain the proper ratio balance between omega-3 and omega-6, and medical researchers are also starting to realize and stress this importance. Jane Collis, an independent researcher not affiliated with the research commented on the study:3
“Commercial food processing destroys a significant amount of EFAs, along with their oxygenating ability... Polyunsaturated oils are unstable and very quickly become rancid. Oxidized fatty acids are dangerous to our health.
Lipid peroxidation and oxidative stress are important factors in this damage. Further damage is also caused by heating polyunsaturated fats in cooking (particularly frying foods).
Many omega 3 research trials did not consider the omega 3/6 essential fatty acid ratio which is vital to the eicossanoid balance. The correct omega 3/6 ratio is fundamental to holistic health for all. I believe that with simple dietary intervention diabetes complications such as retinopathy and nephropathy, could be ameliorated or prevented. ...
Healthy fertility and reproduction fundamentally rely on good nutrition, including EFAs [essential fatty acids] in plentiful supply. Poor maternal health is a cause for concern and may predict poor health in the next generations.”
