Anyway, rather than getting into a big discussion and ending up with me quoting pages from the book "The Mediterranean Prescription," I recommend that you read the link that I provided in my previous post, and then read the book itself if you want more info. The book is written by a doctor (Angelo Acquista), and it contains many pages dealing with the difference in the various fats and omegas, and the best way to maximize the benefits while avoiding the negatives.
[Edit:] I notice from your latest post that you're into bodybuilding. I don't know if the Mediterranean Diet would necessarily be the best for bodybuilders. The Mediterranean Diet is written more for the general population.
