Does taking omega 3 fatty acids from plants improve health ?

Yes.

“Alpha linolenic acid (ALA) and linoleic acid is a essential polyunsaturated fatty acids commonly extracted from plants”

These fatty acids are found in “soybean, nuts, canola oils, flaxseed, and other plant foods”.

A recent study published in BMJ shows that these dietary fatty acids are good for overall health and reduces risk of death. The study found benefits in terms of reducing strokes and heart problems but paradoxically these fatty acids slightly increased the risk of death from cancer .

A word of caution applies to all ‘food and disease’ association reports. Almost every week there are reports of studies exploring associations between “various food/drink” with “various diseases”. Some of them are conflicting and sometimes confusing with a positive study followed by a negative study. So take all food related studies with a pinch of salt !
