What are the most important organic foods to eat?

Answer 1

I agree with previous answer, but have to add soy (in most of the non-organic products it comes from genetically modified crops) and wholemeal cereal / bread, pasta, rice 'cause the pesticides used in growing them remain on the external part (where all the fibre and most of the nutrients are concentrated).

Answer 2

I watched a segment on GMA a while back and they had their nutritionist on. He said that due to the pricy-ness of organic foods, you kinda have to pick your battles (b/c it's hard to buy EVERYTHING organic).
He suggested to go out of your way to buy the following organic:
fish and seafood
chicken, beef, turkey, etc.
milk
Other things such as fruit and veggies aren't as critical.
