The document discusses the differences between organic, conventional, natural, and whole foods. Organic foods are defined and regulated by the USDA and forbid synthetic pesticides and fertilizers. They also require access to outdoors for animals and no antibiotics. Natural has no FDA definition but can be used if no artificial colors or synthetic substances are added. Whole has no regulatory definition. Studies have found no conclusive evidence that organic foods are more nutritious, but organic farming practices may lead to healthier soils and less environmental impact and antibiotic resistance. Organic foods typically cost 20-100% more to produce due to higher labor costs and lack of pesticides and herbicides.
