New Study Questions Fat Consumption-Heart Disease Link
March 21, 2014

An in-depth analysis of existing data on the consumption of different types of fats and their effect on coronary health has concluded that the evidence does not support the guidelines that have been drilled into the public's consciousness for several decades. 
In the article, "Association of Dietary, Circulating, and Supplement Fatty Acids with Coronary Risk: A Systematic Review and Meta-analysis," the team of mostly British researchers extracted data about characteristics of studies already done and evaluated those studies' biases. 
For years, medical guidelines have said that high consumption of polyunsaturated fatty acids (vegetable oils, fish such as salmon and trout) instead of saturated fats (dairy, meat) promotes cardiovascular health. 
But the authors of this article conclude that "current evidence does not clearly support cardiovascular guidelines that encourage high consumption of polyunsaturated fatty acids and low consumption of total saturated fats."
