Nicely researched and written article.
My favorite point you make is:
Your body then converts the ALA into DHA and EPA. But this conversion that your body does is not very efficient, so fish remains the best direct source for EPA and DHA Omega-3.
This has made me focus on fish like salmon, sardines and mackerel for my Omega 3 intake.
Thanks. Yes, I actually had taken a course related to the subject quite a few years ago, but lost all my notes .... there was also a whole section on RNA and DNA which explains some of the reasons why not everyone's body has the same reaction to the same proteins. But that is too complicated to remember :). Thanks for reading.
