All plant, animal or manufactured foods or products that are intended to be put in or on human (or even pet) bodies should be ranked on a scale of 1-100 where 1 would represent a totally natural product and 100 would represent a totally unnatural product. For example, an unwashed apple growing on a wild tree out in the middle of a forest would earn a ranking of 1, while a medicinal tablet or pill made completely from artificial, non-naturally occurring ingredients would earn a ranking of 100. Everything else would rank somewhere in between. This system could also be applied to foods and products for pets. A tax structure may also be created based on this scale to encourage people to eat more natural foods.
