Kosher foods are generally considered MORE desirable, not less. And not just by the Jewish.

GMO foods, and others considered less desirable, are those that benefit from a lack of labeling.

I agree that there is no evidence that GMO foods are harmful, but there is also a lack of data, and I'm not really interested in being a guinea pig for Bayer and Monsanto.

The marginal costs added to food is minimal and I think when it comes to food, more information is better than less.
