Review of heart-healthy oil claims

New health claims for oils approved by the Ministry of health in Canada contrary to the evidence, experts say.

Since the 1960s, public health authorities have advised people to avoid saturated fats or animal like butter or lard for vegetable oils, unsaturated cholesterol benefits. This week, researchers presented a new analysis of data from the "Sydney diet heart study", who studied 458 Australia for men aged 30 to 59 on cardiovascular disease for more than three years.

"The group that was random to Omega-6 safflower oil, increased the risk of death from all causes, as well as death from cardiovascular disease and death due to cardiovascular disease, this was despite significant cholesterol lowering," study author Dr. Christopher Ramsden, a clinical investigator with the national institutes of health in the United States in Washington.

He said half the participants consumed linoleic acid – is unsaturated fatty acids Omega-6 – in the form of safflower oil unsaturated margarine oil walkrtam.

Ramsden having speculated more Omega-6 in your diet can enhance oxidative stress and inflammation in the arteries.

The results add to evidence of unsaturated vegetable oils how not all the same, the nutrition Professor Richard basinit, who teaches at the University of Toronto fatty acids.

"People I ran with the ball that bolionsatoratis good for you, and therefore each individual must be good for you. That turns out not to be true, "basinit said.

Health Canada gave the nod for the vegetable oil industry allow companies to develop new health messages on labels, saying that replacing saturated fat with polyunsaturated fats, including Omega-6 vegetable oils help lower cholesterol.

Basinit said the study this week in the British medical journal "suggesting that Omega-6s may increase heart attack risk threshold should be enough to trigger a re-evaluation of the Health Canada approval of claims.

"There is absolutely no evidence to suggest that we should increase more, when we have" American Heart Association "and potential health claim in Canada saying yes, and this is something we should consume more, it's absolutely backwards with the evidence," he said.

"I've got to reassess."

Health Canada has refused a request from the CBC news to talk about the study, saying it will review research.

Basinit said policy makers should wait for better evidence before allowing the claims.

Also challenging the results of the recommendation "American Heart Association" that people get more Omega-6, which the group said it stands in. By contrast, in the United Kingdom, and France, people are advised to decrease Omega-6 intake, said Dr. Artemis Simopoulos, President of the Center for Genetics, nutrition and health in Washington.

The objective should be to consume a balanced intake of Omega-6 fatty acids and Omega-3, and she advised Canadians and Americans.

Simopoulos said, "we should be less than the amount of Omega-6 rich oils such as corn oil, sunflower, safflower, cotton seed oil, including soybean,". "Increasing the amount of Omega-3 fatty acids in our diet, which can be obtained from oils rich in omega-3s like flaxseed oil, canola oil."

Should not leave consumers with a message about the validity of the claim that Omega-6 fatty acids to lower the risk of heart disease, Simopoulos said in a call to approve health claims in Canada.

In the Australian study, the men got about 15 percent of their total calories from Omega-6. In comparison, Canadians currently gets about seven per cent of their consumption of Omega-6 fatty acids, basinit said.

Dr. Dariush mozavarien studies from the Harvard School of public health in Boston food habits and cardiovascular disease. Mozavarien criticized the 40-year-old Australian study, margarine was used to increase the amount of Omega-6s were too high in fat.

"Some of this effect, the damage could be clearly due to the fact that in the 1970s when he was doing this, I didn't know people from the harms of fat."

For consumers, the hidden messages and switch can be confusing. Basinit are advised to read labels carefully, whether in oils, salad dressings, or processed foods. Like simobolo said, flax and canola are safer options, people might want to stay away from corn and safflower oils and sunflower, which usually make up to five per cent of buyers.
