Dear Ashok, we understand your concern. When comes to organic food it is basically free from chemicals and pesticides, so your body is not exposed these harmful chemicals and pesticide residues. Interestingly, the food that you eat greatly affects the types of bacteria that live inside you. There are so many foods which you can include in your diet to increase good bacteria in the gut, like more raw fruits and vegetables, whole grains, include fermented foods like yogurt which has good bacteria called Lactobacillus. Hope this satisfies your query, would you like to know anything else?
