New Evidence Questions Fatty Acid Intake Guidelines
(Ivanhoe Newswire) – A new study from the University of Cambridge raises questions about current guidelines which limit intake of saturated fats and encourage intake of polyunsaturated fats to prevent heart disease.
A meta-analysis of 72 unique studies with more than 600,000 participants from 18 nations found total saturated fatty acid, whether in the bloodstream or in diet, was not linked to coronary disease risk. Also, when analyzing studies that involved consumption of total monounsaturated fatty acids, long-chain omega-3 and omega-6 polyunsaturated fatty acids, and arachidonic acid, there were no substantial associations between intake and cardiovascular risk.
“These are interesting results that potentially stimulate new lines of scientific inquiry and encourage careful reappraisal of our current nutritional guidelines,” lead author Dr. Rajiv Chowdhury was quoted as saying. “Cardiovascular disease, in which the principal manifestation is coronary heart disease, remains the single leading cause of death and disability worldwide. In 2008, more than 17 million people died from a cardiovascular cause globally. With so many affected by this illness, it is critical to have appropriate prevention guidelines which are informed by the best available scientific evidence."
