If you're one of the 3 million people suffering from an allergy to gluten then here's some good news. More and more products are donning this trademarked symbol that lets you know they are certified gluten free by the Gluten Free Certification Organization (GFCO). This group inspects products to ensure that they contain less than 10 parts per million (ppm) of gluten, which is an amount low enough not to cause a reaction in someone with this allergy. If a product passes the test, like this Stonyfield Farms yogurt then the manufacturer is allowed to add this symbol to their label.

Gluten is the plant protein found in wheat, rye, barley, and some oats. People allergic to gluten suffer from severe stomach problems, and in order to avoid symptoms the only option is to avoid it. That's why it's imperative they know which foods are safe. If you're interested in seeing the complete list of products labeled with this symbol, check out the GFCO website.
