Doctors Health Press, a division of Lombardi Publishing Corporation, and publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new study finding that levels of linoleic acid, a heart-healthy fatty acid, decrease with age. Low levels of linoleic acid can be a risk factor for heart disease.
As Doctors Health Press e-Bulletin (http://www.doctorshealthpress.com/food-and-nutrition-articles/these-heart-healthy-fatty-acids-drop-as-you-age) notes, fatty acids have a big role to play in keeping the body healthy. Countless studies have shown that omega-3 fatty acids are key nutrients for protecting against heart disease. But when it comes to preserving heart health, linoleic acid is equally important.
As the article “These Heart-Healthy Fatty Acids Drop as You Age” reports, researchers looked at fatty acid levels and how they change as people age. The researchers noted that higher linoleic acid levels have been associated with improved heart disease outcomes. For this reason, the researchers wanted to find out what happens to the body’s ability to utilize fatty acids as it grows older.
As the Doctors Health Press e-Bulletin article outlines, fatty acid profiles from about 160,000 patients (48% from males, 52% from females) were measured by the research team. Here’s what they found:
- Compared to men, women generally had higher trans fat levels
- Saturated (41% of total) and trans fats did not change much by age, whereas monounsaturated fats tended to rise slightly
- Of the two major omega-6 polyunsaturates, arachidonic and linoleic acids, the former was unchanged across decades, whereas the latter decreased by about two percent
- Omega-3s increased by about 1.5% across decades.
- Both omega-3 and linoleic acid stabilized after age 70.
Doctors Health Press e-Bulletin concludes by advising those who are in their 50s or 60s to consider boosting their intake of linoleic acid to help protect their hearts. Linoleic acid can be found in safflower, sunflower, grape seed, and primrose oils
