Antioxidants can protect against omega 6 damage -- or promote it
Given omega 6 fatty acid's reputation for promoting cancer -- at least in animal studies -- researchers are examining the role that antioxidants play in blocking the harmful effects of this culprit, found in many cooking oils. After all, antioxidants are supposed to prevent DNA damage. But employing antioxidants could backfire, say researchers. (Source: ScienceDaily Headlines)

Saturated fats and heart disease link 'unproven'
ConclusionIn contrast to current recommendations, this systematic review found no evidence that saturated fat increases the risk of coronary disease, or that polyunsaturated fats have a cardioprotective effect.Similarly, there was no significant association between the levels of total omega-3 or omega-6 polyunsaturated fatty acids and coronary disease. This lack of association was seen in both cohort studies, which looked at dietary intake or circulating levels the in blood, and in randomised controlled trials that had looked at the effect of supplementation. There was also no significant association between total saturate...

You are what you eat: Low-fat diet changes prostate cancer tissue
This study is a follow-up to a 2011 study by Aronson and his team that found that compared to a traditional, high-fat Western diet, a low-fat diet with fish oil supplements eaten for four to six weeks prior to prostate removal slowed the growth of cancer cells in human prostate cancer tissue.
That short-term study also found that the men on the low-fat fish oil diet were able to change the composition of their cell membranes in both the healthy cells and the cancer cells in the prostate. They had increased levels of omega-3 fatty acids from fish oil and decreased levels of the more pro-inflammatory omega-6 fatty aci...

Not All PUFAs Created Equal, Say ResearchersNot All PUFAs Created Equal, Say Researchers

Vegetable Oils Do Not Cause Inflammation
The consumption of vegetable oils which are rich in an essential nutrient called linoleic acid (LA) is not linked to an increased risk of inflammation, according to researchers at the University of Missouri (UM). We have known for years that linoleic acid helps lower cholesterol levels as well as reducing the risk of developing heart disease. However, there have been recent claims that Americans may be consuming too much vegetable oil. A previous study suggested that fish oils reduce inflammation but vegetable oils do not...

Which Fats Really Are Good For Your Heart?
WebMD Medical News
By Kathleen Doheny
Reviewed by Brunilda Nazario, MD
Feb. 6, 2013 — The standard advice about which fats are best for heart health is under debate again.
Triggering it is new research, just published in BMJ, finding that a form of omega-6 fatty acid found in vegetable oils may actually boost heart disease risk. Omega-6 fatty acids are a type of polyunsatured fat, which has generally been considered heart healthy.
The new findings could significantly alter the advice about which type of fats to eat, some experts say. The new research warrants another look at the current recommendations, says a spoke...

Discussing Dietary Fats
Replacing saturated animal fats with polyunsaturated fats rich in omega-6 linoleic acid may not be beneficial for heart patients, researchers have claimed. Linoleic acid is present in high amounts in some commonly used vegetable oils such as corn, sunflower, safflower and soybean. � Swapping saturated fats like butter or lard for polyunsaturated vegetable oils and spreads made from them is a common suggestion for those looking to switch to a heart healthy diet. � Researchers recovered missing data from the Sydney Diet Heart Study in the 1960s...

This study has several strengths. It was a randomised controlled trial, using just one type of oil to increase consumption of polyunsaturated fatty acids.
. The study also has its limitations. The dietary data collected during the original trial does not contain enough information to rule out the possibility that changes in other nutrients could have caused the effect seen.

Could 'healthy' margarine fats be bad for you?
Conclusion
Contrary to received wisdom, this research suggests that not all polyunsaturated fatty acids are good for the heart (the so-called "cardioprotective effect").
This study has several strengths. It was a randomised controlled trial, using just one type of oil to increase consumption of polyunsaturated fatty acids.
However, the study also has its limitations. The dietary data collected during the original trial does not contain enough information to rule out the possibility that changes in other nutrients could have been caused the effect seen.

Wrong fat in pregnancy diet 'may make kids fatter'
Conclusion
This study of 293 mother-child pairs finds that the mother’s blood levels of n-6 PUFA during late pregnancy influence her child’s body fat levels, with higher blood levels equalling higher child fat levels. The researchers say that n-6 PUFA, derived from plant oils are known to have an influence on fat development. Therefore, they say the observed association may suggest ‘prenatal PUFA exposure could be linked to risk of offspring obesity’.
However, though this study has merits, including a representative population sample and carrying out detailed assessment of both the mothers and children, it is diffi...
