Sticker shock
Ever notice those stickers on your tomatoes, apples or onions? Me, too. But did you ever wonder what those numbers mean? Me, neither. I thought the codes were randomly assigned by the supermarket.
Nope, it turns out that those codes can tell you a lot about your food, according to this great book I spent four hours reading yesterday! (The book is a little old, so I've been cross-referencing the information. I'm fascinated by what I've learned, and I took notes. I'll share more this week!)

Conventionally grown produce bears a four-digit number beginning with a 4 or sometimes a 3.
GMO (genetically modified organisms) produce is labeled with a five-digit code beginning with an 8. (Now you know how to avoid the icky stuff!)
Organic produce also has a five-digit code, but organic codes begin with a 9.
Look before you buy!
Example:
4011= conventional bananas
84011=genetically modified bananas
94011=organic bananas
