From 1956 to July 2013, there were 32 observational studies (512420 participants) of fatty acids from dietary intake; 17 observational studies (25721 participants) of fatty acid biomarkers; and 27 randomized, controlled trials (105085 participants) of fatty acid supplementation. Current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats.
