Clean eating means that you are eating food as close to its natural state as possible. Lots of fresh fruits and vegetables, lean meats without a lot of breading or extra stuff added to them. Also, choosing whole grains over processed grains. Whole wheat over white flour, etc. Cathe's example once of declining clean food was this: Apple (clean), applesauce, apple pie.
