Higher Intake of Alpha-Linolenic Acid May Decrease Risk of Death From Cardiovascular Disease

Alpha-linolenic acid (ALA) is a type of omega-3 fatty acid found in plants. It is found in flaxseed, canola, soy, and perilla oils, walnuts, pumpkins, and tofu. According to a new study, high intake of ALA may be associated with a lower risk of death from cardiovascular disease and coronary heart disease.

For their study, the researchers used data from 41 clinical studies that included 1,197,564 participants. In each study, ALA intake was evaluated, and all incidences of mortality were recorded.

The researchers found that high intake of ALA was associated with an 8% lower risk of death from cardiovascular disease and an 11% lower risk of death from coronary heart disease. It was also associated with a 10% lower risk of death from any cause.

Specifically, an increase of one tablespoon of canola oil or half an ounce of walnut oil daily was associated with a 5% lower risk of death from cardiovascular disease.

The study was conducted by researchers from Tehran University of Medical Sciences. The study was published online ahead of print on October 14, 2021 in the journal BMJ.
