organic food A broadly defined category of food which, in the purest form, is grown without chemical fertilisers or pesticides and sold to the consumer without adding preservatives and synthetic food enhancers; it is widely believed by advocates of alternative healthcare that organically grown foods are safer and more nutritious; however, there are no compelling data that demonstrate clear superiority of organic over non-organic foods. Organic products may be certified by voluntary organisations or government bodies, such as “Farm-Verified organics” and “California Certified Organic Farmer”.
