A study showed that high intake of alpha linolenic acid (ALA) found mainly in nuts, seeds, and plant oils is associated with a lower risk of death from all causes and specifically from diseases of the heart and blood vessels. Study was carried out on around 120,000 participants aged between 18 and 98 years who were monitored for between two and 32 years, and they accounted for factors such as age, weight, smoking status, alcohol consumption,and physical activity. After thoroughly assessing each study for bias, the researchers found that a high intake of ALA was associated with a 10%, 8%, and 11% lower risk of mortality from all causes, cardiovascular disease, and coronary heart disease,respectively. This is equivalent to 113 fewer deaths per 10,000 person years for all causes, 33 fewer cardiovascular disease deaths,and 23 fewer coronary heart disease deaths. A higher intake of ALA, however, was associated with a slightly higher risk of cancer mortality, equivalent to 63 extra cancer deaths for the highest compared with lowest levels of ALA intake.A dose-response effect was found for dietary ALA intake and cardiovascular disease mortality, such that a 1g per day increase in ALA intake was associated with a 5% lower risk of cardiovascular disease mortality. Higher blood levels of ALA were also associated with lower risks of mortality. As such, they say their study adds to evidence of the potential health benefits of polyunsaturated fatty acids.Further studies should examine the association between ALA and a wider range of causes ofdeath to provide a more comprehensive assessment of the potential health effects of ALA as well as to examine whether specific foods rich in ALA are differentially associated with mortality from cancer and other causes.
