Eat More Linoleic Acid

This form of omega-6 fatty acids may help you live longer.

Every athlete knows that education is a crucial part of performance. Sport and exercise research, insight from top trainers, science, and technology help you to better understand your body so you can craft a healthier lifestyle, workouts, and recovery plan.

In our daily news series, experts address some of the latest fitness research, nutrition, style, and health stories.


THE SCIENCE
A new study from researchers at the University of Eastern Finland shows that men who had the highest levels of linoleic acid in their blood, a biomarker for high intake, were 43 percent less likely to die early than those with the lowest levels of the nutrient.

EXPERT INSIGHT
A form of omega-6 fatty acids, linoleic acid improves glucose and insulin metabolism, prevents liver fat from accumulating, and lowers LDL cholesterol, says study author Jyrki Virtanen, Ph.D., adjunct professor of nutritional epidemiology at UEF’s Institute of Public Health and Clinical Nutrition in Joensuu. The study was conducted on men, but the links between linoleic acid and health are most likely similar in women, he explains.

Increasing your consumption of the nutrient can reduce disease risk factors in a matter of weeks or months, Virtanen says. “However, because you can’t feel if your blood cholesterol profile is off or if you have increased inflammation in your body, you may not feel differently.”

THE BOTTOM LINE

There’s no official guideline, but the National Academies of Engineering, Science, and Medicine suggest men and women aim for 17 and 12 grams of linoleic acid per day, respectively. Get your dose from vegetable oils and unsalted nuts and seeds, Virtanen says, like sunflower oil (10 grams per tablespoon) and pine nuts (eight grams per ounce).
