Also, don't eat boxed foods or foods that went through multiple stages of processing. In Defense of Food by Michael Pollan spells it out very well, but I'll just give you my simple definition: Eating healthy is as close to eating dirt without actually eating dirt. Produce, grain, cheese, 1/2 pound to a pound of meat a week[1], and whatever else Marion Nestle recommends[1.5].
Just imagine what primitive man would eat. He would spend most of his days eating what grew from the ground and when they finally hunted down meat, they would eat their catch as a group[2]. That doesn't mean you have to do exactly that, but try to keep your eating habits in sync with what it was originally adapted to consume not what hyper stimulates made you believe it wanted to consume[3].
Now don't go about forcing yourself to eat stuff you don't enjoy. In the same manner jasonkester engages in something he enjoys that have the "side effect" of being healthy (I still think these activities are something we were adapted to engage in the first place), find foods you find delicious but also happen to be something that isn't processed. I can assure you that there is plenty of "healthy" or "natural" foods out there that you would enjoy[4].
