The GMO Free Project of Tucson recently held a series of dinners at local restaurants to help the public understand how to avoid genetically modified organisms.

Organizers of the "pure food dinners' worked with the chefs to make sure all of the ingredients were not genetically modified foods.

Melissa Diane Smith, director of education for the project, says eating GMO free can be difficult because food producers are not required to say they are using genetically modified foods in their products.
