What are the benefits of alpha-linolenic acid (ALA)?
What is ALA?
Alpha-linolenic acid (ALA) (see Learning Lab for glossary) is one of the fats that makes up Omega 3 polyunsaturated fatty acid, and is found in plant oils such as flaxseed, pumpkin seeds and walnut oils. Seed oils are the richest source of ALA. Some studies have shown ALA may help to maintain normal cholesterol levels.
Alpha-linolenic acid has undergone numerous clinical trials demonstrating its efficacy at helping to maintain normal cholesterol levels. Because our bodies are unable to produce ALA, it needs to be taken through food or supplementation.
A number of clinical trials have shown the ability for alpha linolenic acid to maintain healthy cholesterol levels. ALA has been compared in a 2004 clinical trial1 to the average American diet as well as to Omega 6.
In 2002 a study2 looked at Rapeseed oil (high in Omega 6) and Olive oil (high in Omega 9) as well as Camelina oil (high in ALA Omega 3) and found the Camelina oil performed favourably.
A 2006 trial3 compared alpha-linolenic acid to EPA & DHA from fish oil and looked at the effects on cholesterol levels of each.
And a large study4 in 2003 looked at the daily consumption of 1575 patients, who were invited to detail their intake of ALA, and then who's plaque build-up in the arteries was measured. The amount of fish consumed did not make a different to plaque build-up in the arteries. Alpha linolenic acid on the other hand, was proven to maintain healthy cholesterol levels.
