That is exactly what I have said. But the problem is where to find good food whe everything is poisoned with pesticides and other chemicals? And because of the way that it is grown, todays food doesn't have so much nutritive values like it had before.
You just can't find 100% healthy food because whole world is poisoned with multiple
pollutants and their gonna stay with us for a long time. Best you can is to avoid just those obvious poisons and unhealthy food. But organic food is still far better than processed with chemicals.
