As opposed to the popular belief that fats are harmful, they are actually essential macronutrients that help the human body derive energy to function. ALA or Alpha-linolenic acid is an essential omega-3 fatty acid found in several plant-based foods. It is necessary for normal human growth and development. According to the American Heart Association, ALA is best found in soyabean, canola oil, walnuts, flaxseeds and pumpkin seeds.
A recent study published in the BMJ, a weekly peer-reviewed medical trade journal, found that diets with higher levels of ALA had associations with overall lower mortality risk.
The research is a systematic review and meta-analysis of 41 different studies. The meta-analysis looked at all-cause mortality, cardiovascular disease mortality, coronary heart disease mortality and cancer mortality. The researchers also observed both dietary intake of ALA and blood levels of ALA.

The study concluded that high ALA intake was associated with a lower risk of death from all causes. It was also associated with lower mortality risk from cardiovascular disease and coronary heart disease.
Researchers particularly noted that an increase of 1 gram intake of ALA per day was associated with a 5% lower risk of cardiovascular disease mortality. And while the results indicate potential benefits of ALA intake, it also states a need for continued research regarding recommended levels of ALA intake.
