Mark Sisson’s site seems to do the best job at simplifying good fat/bad fat:

Fats to eat:

- Cream, eggs, butter

That’s right – I’m recommending saturated fat. Irresponsible of me, I know. Actually, provided you’re eating organic dairy and eggs, and you’re not getting crazy with the portions, saturated fat is not the monster it’s made out to be. I personally am more concerned about triglycerides and inflammation than I am about cholesterol, and refined fat and sugar have the most impact on these two health wreaking balls. I’m not saying cholesterol doesn’t matter; it does. It just doesn’t matter as much as you think. You can enjoy a little saturated fat.

- Nuts, avocados, fish

Omega 3’s, people!

- Coconut oil, walnut oil, avocado oil, olive oil

Put down the corn, soybean and canola oil. These may be unsaturated, but that doesn’t make them healthy (they are still refined, and contain some undesirable fatty acid chains). Liven up your meals, give your tastebuds something to live for, and try out new, omega-3-rich oils. Go and drench thyself. Stat.

Fats you’re too good for:

- fried anything, breaded anything, processed anything, packaged anything, not-natural anything. Keep these junk fats away from your precious body! I mean it!
Why eat fat:

Well, for starters, fat doesn’t make you fat. Fat also helps with stress management, cognition, mood, sleep, energy, weight management, healthy tissues, skin and hair – even digestion and nutrient absorption.

That should give you a good basic overview.  Don’t forget your Omega-3’s.  Ask about them at Athlon Elite!
