Omega-3 Supplements Fail in Preventing CVD

Consuming n-3 fatty acids daily did not reduce cardiovascular morbidity or mortality in an Italian study of over 12,000 patients with risk factors but no history of a heart attack. Half were randomly assigned to 1 gram of n-3 fatty acid supplements, the other a half received a placebo of olive oil. While this study did not account for dietary variability from person to person, it does underscore that providing a supplement without a known dietary need may not be beneficial.

PositiveTip: Choose to consume a diet that provides sufficient n-3 fatty acids from natural sources.
