When budgets are tight, it’s important to know which fruit and veg are safe to buy non-organic, and which are the ones that you really should be shelling out the extra for.

The Environmental Working Group (who publishes this printable pdf list for keeping in your wallet) recommends eating a varied diet, washing all your fruit and vegetables before eating, and buying organic when possible.
