The demand for organic foods began with fruits and vegetables when there were reports of pesticide residues in them. However, the popularity of organic foods has now extended to food grains, pulses, tea, spices and even oilseeds. 'Organic foods have gained popularity because people have become aware of their benefits. They contain no chemical pesticides and fertilizers and are grown naturally with manure or compost and only natural pesticides and insecticides are used,' said Dr. Saurabh Arora, MD (Auriga research and Director at Arbro Pharmaceuticals) and Founder of Food Safety Helpline.
