Key Findings:
This review strongly acknowledges the essentiality of ALA. Most attention has been given to EPA and DHA with significantly fewer studies on ALA from plants. The authors indicate that this is unfortunate as ALA may have independent, therapeutic properties similar to those of other n-3 fatty acids. It may also be of particular importance for neural development. Results of many of the studies described here indicate that ALA is not only essential, it also has therapeutic properties.
ABSTRACT:
Consumption of omega 3 fatty acids is known to have health benefits. For many years, the importance of the only member of the omega 3 family considered to be essential, alpha-linolenic acid (ALA), has been overlooked. Current research indicates that ALA, along with its longer chain metabolites, may play an important role in many physiological functions. Potential benefits of ALA include cardioprotective effects, modulation of the inflammatory response, and a positive impact on both central nervous system function and behavior. Recommended levels for ALA intake have been set, yet the possible advantages of its consumption are just being revealed. (Authors abstract)
