If they contain olive oil you should keep them in a cabinet or something covered instead of out on the counter where sun can hit it. If sun hits olive oil (for most other oils as well) it can cause oxidation and render it rancid. It does not have to be refrigerated, but it should be covered.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
