I've been in the grocery business for more than 30 years. Since I opened my first store in Weaverville, California in 1977, I've talked to customers about everything from diet choices to recipes to organic gardening. Over that time I've had the opportunity to see firsthand what Whole Foods Market customers want­ is information about the food they're buying.

GMO labeling is standard practice in 50 other countries around the world, including Japan, China, Russia, and across Europe. Foods containing GMOs are produced and labeled at little or no extra cost, we know it can be done without seeing food costs go up.

I support Prop 37 because I believe that our customers have the right to know how their food is sourced, grown and produced. I see this as a fundamental right - the right to know and the right to choose freely based on that knowledge. Prop 37 is an important and historic first step forward for transparency on GMOs in our food system.

Prop 37 is our chance to stand for greater transparency and the customer's right to know what is in their food. While it is not a perfect instrument, it is on the right side of history and I am voting yes.
