The two actresses met with lawmakers on Capitol Hill and urged them to introduce legislation for mandatory genetically modified organism labelling on food products.

Appearing as an advocate of the Just Label It coalition, Paltrow said, "I’m not here as an expert, I'm here as a mother, an American mother, who honestly believes that I have the right to know what’s in the food I feed my family. I’m not an intensely political person."

The Just Label It activists are fighting the Safe and Accurate Food Labeling Act, which passed last month (Jul15) and blocked states from requiring labels identifying food made with GMOs.

Paltrow prefaced her trip to Washington, D.C. last week by posting on Facebook, "Next week I am going to DC to speak with members of the Senate about voting against a law that would let genetically modified organisms into our food supply without any labels!

"The evidence suggests that GMOs are an environmental disaster, both in the long term and in the short. But I am not asking you to weigh in on whether they are good or bad. We just want a label!"
