Omega/Mediterranean diet?

I don't know much about THE Mediterranean diet, but being of Med lineage, I know that there is a big slant towards whole foods. Fish is also a big part of the diet. And lets not forget garlic, wine and lots of fresh veggies. What source are the fats coming from? A decent rule of thumb is that if the fat is liquid at room temperature, it's far better than fats that are solids at room temp. Granted, we're speaking again about whole foods. Sesame, peanut and olive oils, etc. as opposed to butter. Omega 3 (and 6 to a lesser degree) fatty acids are shaped in a certain way that allow them to be used by our bodies for good stuff. Bad fats are shaped in a way that makes our body look at them and go "What the heck is this??" Just my 2 psi.
