From Fitness Attitudes:
A better nutritional program is the introduction of foods of higher quality in place of lower quality ones. The closer the food comes to the natural state in which it occurs, or the closer to its raw, unfired form, the higher its quality. The higher the quality of food we eat, the quicker we recover from disease, provided we are able to digest and assimilate properly. Version 3 may include unspecified updates, enhancements, or bug fixes.
