we have discussed this topic many times here and on evo. there is a lot of bad info out there about eggs but here goes again:
1. you need to buy humane friendly pastured eggs, these will be free of disease and quality will be highest. or you buy from a local farm that pastures their chickens
2. when you cook eggs you leave the yolk runny.. never over cook.. if you buy cheap walmart eggs you will get sick eating them this way, but good quality eggs you will be fine
3. don't use oils or drench them in oil. i use a 0 calorie coconut spray
