According to a 2010 report from the President’s Cancer Panel, eating foods that have been grown without pesticides, fertilizers, or hormones can reduce the risk of cancer. They also caution against drinking water from bottles that contain BPA, and heating plastic food containers.
Studies show that about half of all synthetic pesticides are carcinogenic, and these chemicals leave a residue on food that can then be ingested. Foods that have been grown organically, however, may still harbor some residue, so it’s important to wash all of your fruits and vegetables before preparing them.
