More than 15 million pounds of artificial dyes are used each year to color food and make it more tempting. But, according to the Center for Science in the Public Interest, those dyes could contain chemicals that may cause cancer as well as allergies and hyperactivity in children.
The CSPI is encouraging the FDA to ban the dyes from supermarket shelves.
While not all the dyes have been proven harmful, the CSPI argues that they offer no nutritional value and only cause unnecessary risk.
