The site was developed for the 53 percent of Americans who say they would avoid GMOs if labeled. It lists popular brands that don't use ingredients from the eight GM crops such as GM soy and corn. It also lists dairy products that don't allow the controversial GM bovine growth hormone.

IRT's executive director Jeffrey Smith, who hears from thousands of consumers on trips around the United States, frustrated at the lack of labeling, says, "Our new Web site gives consumers back the power to make an informed choice."

Maria Emmer-Aanes, director of marketing and communications for Nature's Path, North America's No. 1 organic cereal manufacturer, says, "We have been at the forefront of the organic food movement since the inception of the company almost 25 years ago, and have never supported the use of GMO ingredients." She says, "We are extremely concerned about transparency and letting consumers make an informed choice about whether or not they eat GMOs, so we applaud the creation of this resource and are happy to be listed on the Web site."
