Thanks for your reply. I'm just worried about the part when it is being said "So far modern science". What happens if anything surfaces in the future. Many medicines and food products that are banned in other countries, are still being sold in India. Oats and Wheet flour we consume here are already having a huge amount of Gluten. All these were started thinking there will be no harm. But today research works are proving their harmful effects. Well that's a different story.
Maybe DNA from food may not affect human's genome directly but nutrients in the food does affect genes right? What if GMO creates an imbalance in the nutrients and that in turn indirectly affect the human genome?
