Taking omega-6 supplements, like those from sunflower or corn oil, doesn’t appear to protect against heart disease, according to clinical trial data.

Original Statement

“In randomized, controlled trials, relative risks for coronary disease were ... 0.89 (CI, 0.71 to 1.12) for ω-6 polyunsaturated fatty acid supplementations.”
