There are certain key foods that are more important to buy organically grown because some crops are more heavily treated than others. Every year the Environmental Working Group include produce with the highest pesticide loads into their “Dirty Dozen” list.
Each of the following foods tested positive for a number of different pesticide residues and showed higher concentrations of pesticides than other produce.
Strawberries can help prevent night sweats, lower blood cholesterol levels, help prevent heart disease and strokes, dissolve tartar deposits on teeth, protect against viruses and cancer, protect against DNA damage and skin disorders. But unfortunately, strawberries are at the top of the list of foods with pesticide residues. According to Environmental Working Group 300 pounds of pesticides are applied to each acre of conventional strawberries. U.S. Department of Agriculture tests found that they are the most likely to be contaminated even after they are thoroughly washed before eating.
