Recommendations on Dietary Fats May Be Misguided.

Over 39 months, men instructed to reduce saturated fats to less than 10% of intake and to increase omega-6 linoleic acid, a polyunsaturated fat, to 15% of intake had a higher risk of dying from all causes, as well as from cardiovascular and coronary heart disease, compared with men who received no dietary advice. The study involved 458 men aged 30 to 59 years who had recently had a coronary event. The BMJ findings, based on recovered data from the Sydney Diet Heart Study, suggest that the American Heart Association guidelines on omega-6 polyunsaturated fatty acids may be misguided.
