Many authorities recommend that we eat only organic foods. First, we need to understand what we mean by organic.
Produce is organic if it is grown without pesticides.
Meat and poultry are organic if the animals' feed has been grown without pesticides, though they still may have received antibiotic and hormone injections. One reason for buying organic is that the National Cancer Society states that pesticides are the third greatest cause of cancer. Some of that includes those who work with pesticides and migrant workers who are made to pick grapes while the vineyards are being sprayed from airplanes. Washing fruits and vegetables only removes some of the pesticides. Much remains inside.
