There are a few caveats with organic, however, and the first one is that organic foods are usually more costly. It can sometimes be hard to find a wide variety unless you are eating "with the seasons" (meaning, consuming certain fruits and vegetables when they are naturally in season). Here is a list of the so-called "Dirty Dozen" list of produce that contain the most amount of pesticides so if you can, try and purchase these as organic. Of course, not eating certain fruits and vegetables because they aren't organic isn't a good choice either. Fruits and vegetables are GREAT for you no matter what. Another plus? No need to count calories when eating whole fruits and vegetables - fill up!!
- Nectarines (imported)
- Grapes (imported, especially from Brazil)
- Sweet Bell Peppers
- Blueberries (domestic)
- Kale/Collard Greens
Whether or not to eat organic is a personal choice; however, if you can avoid the "Dirty Dozen" and choose organic in these instances, all the better. Some examples of produce that is considered "Clean" (by the Environmental Working Group) and therefore much safer to eat in its conventional form are: Onions, sweet corn, pineapples, avocado, asparagus, sweet peas, mangoes, domestic cantaloupe, kiwi and watermelon.
