How to remove acidic pesticides from produce

About the only downside to eating any of these healthy blue foods is the fact that most products you buy at the store (except organic) will have pesticide residue on it. The good news is that there is a simple fix: Soak your produce in alkaline water for about 20 minutes. Alkaline water neutralizes pesticides, rendering them harmless so they can be safely rinsed away.
