If you're like us, you feel better knowing where your food comes from. Did you know that you can trace the origin of your milk from a code on the carton? More than likely, there's a handy little code on your carton of milk or tub of yogurt that tells you exactly where it's from. Run to the fridge for a peek at the code—we'll wait right here—and then look it up on Where is My Milk From?.

Bonus tip: identify your produce

Before we go, let's run through a quick refresher on how to tell if your produce is organic, conventional or genetically modified. Take a look at that annoying little sticker you normally peel off and flick into the trash. You're looking for the Price Look Up (PLU) code, which is set by the International Federation for Produce Standards.

• Organic produce 5-digit PLU number beginning with 9
• Conventional produce 4-digit PLU number beginning with 4
• Genetically modified (GMO) produce 5-digit PLU beginning with 8
