How about just saying I follow a high quality food diet? Followed by I try to only eat foods that:
Are grown without pesticides and chemical fertilizers.
Are fresh, organic and not genetically modified.
Contain no added growth hormones, antibiotics or other drugs.
Do not contain artificial ingredients or preservatives.
Did not come from a factory farm.
Are grown with the laws of nature in mind - meaning animals are fed their native diets and have free range to be outdoors.
Grown in a sustainable way - using minimal amounts of water, protecting the soil from burn out and turning animal wastes into natural fertilizers.
