Omega-6 fats promoted as heart-healthy

[Guest guest]

Check out this recent " science advisory " published in Circulation:

Journal of the American Heart Association. (via ScienceDaily)

Here are some of the claims:

" Observational studies showed that people who ate the most omega-6

fatty acids usually had the least heart disease. Other studies

examined blood levels of omega-6 in heart patients compared with

healthy people and found that patients with heart disease had lower

levels of omega-6 in their blood. "

" In controlled trials in which researchers randomly assigned people to

consume diets containing high versus low levels of omega-6 and then

recorded the number of heart attacks over several years, those

assigned to the higher omega-6 diets had less heart disease. "

" For example, in the cells that form the lining of blood vessels,

omega-6 PUFA have anti-inflammatory properties, suppressing the

production of adhesion molecules, chemokines and interleukins — all of

which are key mediators of the atherosclerotic process. " Thus, it is

incorrect to view the omega-6 fatty acids as `pro-inflammatory,' "

explained. " Eating less LA will not lower tissue levels of AA

(the usual rationale for reducing LA intakes) because the body tightly

regulates the synthesis of AA from LA. "

have you seen any of these studies? Any comments?
