As reported in the American Heart Association's January 26, 2009 online newsletter, Circulation, omega-6 fatty acids typically found in nuts, seeds and vegetable oils have gained an undeserved reputation as being bad for your heart health.
A great deal of discussion in the world of nutrition has given omega-6 fatty acids a bad reputation, which, according to the American Heart Association is unfounded. The debate came about because one of the components of omega-6 fatty acids, called arachidonic acid, is a “building block” for some inflammation-related molecules. This had led to concern that the fatty acids would lead to a greater risk of heart disease.
The committee spent two years assessing more than 24 controlled and observational studies. The studies showed that people with diets high in omega-6 fatty acids experienced a lower incidence of heart disease. The advisory committee suggests that between 5 and 10 percent of our calories come from omega-6 fatty acids. These polyunsaturated fatty acids affect growth and development, and they can help protect arteries from forming plaque when used instead of saturated fats. Recommended daily dose ranges from 12 to 22 grams depending upon age, gender and level of physical activity.
"There has been a lot of talk about this concern," says Dr. Robert H. Eckel, a professor of medicine at the University of Colorado and a past president of the American Heart Association. "I'm glad that the American Heart Association went ahead and looked into the evidence of such a harmful effect, and it just isn't there. This will comfort everyone who likes vegetable oil as part of a healthy diet."
