Eat real food
Food that is processed, man-made, and fabricated isn't eaten by animals...
So why do we eat it?
Next time you think about spending a few bucks on fast food, try buying some groceries, and putting that money towards a healthy home-cooked meal.
It might take more time, but believe me it is worth it in the long run.
EDIT: For all those playing devil's advocate on the wording; Yes, I understand that Milk is manipulated by man, churning it to turn into butter. But it is still a natural product. The point of the post is to:
Eat. Real. Food.
