Scientists from Tehran and Abadan Universities (Iran), University College Bjerknes (Norway), Imperial College London (UK), Karolinska Institute (Sweden), McMaster University (Canada) stated that saturated fatty acids contained in nuts, soy. The researchers' findings are based on an analysis of 41 scientific papers published from 1991 to 2021, according to Naked science.

The research involved about 120 thousand people aged 18 to 98 years.. Scientists have studied the effects of alpha-linolenic acid (ALA) on health. Factors such as smoking, alcohol consumption and sports were taken into account.

It turns out that regular consumption of foods that contain ALA reduces the risk of death from all causes. Thus, mortality from cardiovascular diseases decreased by 10.8%, and from coronary heart disease - by 11%..

Increasing the dose of alpha-linolenic acid by just one gram (one tablespoon of canola oil or about 14.7 milliliters of walnut oil) reduces the risk of death from cardiovascular disease by 5%.

However, ALA should not be abused.. This acid may cause cancer, researchers say. But this risk is small:

63 additional deaths per 120 thousand people.
