Do people have the right to know what is in the food they eat?

I am quite concerned with the fact that genetically modified organisms (GMOs) have been included in many processed foods for at least 10 years now in the USA.  Many people may not be aware of this fact. The companies who use these ingredients in their foods are not required to label those GMO ingredients.  I believe in democracy and certainly when it comes to food---who doesn't eat?  We all have the right to make informed decisions about what we accept into our bodies, however, we can NOT exercise that right if food is not properly labeled.  I want to enjoy food democracy now here in the USA in the same way that so many other countries already enjoy it. How is that?  Because in those countries, unlike the US and Canada, GMO labeling is required by law.
