How can we minimise the impact of pesticides on fruits and vegetables?

You can soak your fruits and vegetables in plain water for about 30 minutes after you buy them. This will allow for some amount of the chemicals and pesticides to be removed. Please do not add anything to the water. Also, soak your vegetable before chopping them. 

If you are highly concerned about this, buy organic fruits and vegetables. There are many brands selling authentic organic produce today, and they can deliver the produce to your home. Please do your own research to identify those organic brands.
