Recent studies have questioned the need to reduce the intake of saturated fatty acids in the diet and to increase that of polyunsaturated fatty acids. In an article in the British Journal of Nutrition based on a desk study, researchers of Wageningen University, part of Wageningen UR, clarify what is the best intake. A low intake of saturated and trans fatty acids, a minimum intake of 10 grams per day for women and 15 grams per day for men of the polyunsaturated fatty acid linoleic acid and a minimum intake of 250 mg per day of certain fish fatty acids give the best guarantee of a low risk of a heart attack. http://medicalxpress.com/news/2011-06-intake-fatty-acids-heart.html Health Thu, 30 Jun 2011 09:32:27 EST news228645094 The fishing industry usually discards fish livers, but a team of researchers from the University of Almeria (Spain) has confirmed that they are a good source of polyunsaturated fatty acids, which are beneficial to health. Anchovies are one of the fish whose livers contain the highest levels of these substances. http://medicalxpress.com/news/2011-04-fish-livers-beneficial-fatty-acids.html Health Thu, 28 Apr 2011 13:05:30 EST news223214702 Eating more n-3 polyunsaturated fatty acids, commonly known as omega-3 fatty acids, may help carriers of a genetic variant on the perilipin 4 (PLIN4) gene locus lose weight more efficiently. Based on this observation, researchers at the Jean Mayer Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University identified a microRNA (miRNA) which may elucidate the underlying biological mechanism. http://medicalxpress.com/news/2011-04-microrna-gene-diet-interaction-obesity.html Genetics Wed, 20 Apr 2011 17:20:06 EST news222538790 We are all encouraged to eat polyunsaturated fatty acids, as these are "good for us". The (relative) levels of particular classes of polyunsaturated fatty acids have been associated with a plethora of human illnesses. The latest findings of Walter Arnold and his group at the University of Veterinary Medicine, Vienna suggest that changes in fatty acid concentration of inner organs might be largely independent from diet composition.
