A pair of food bloggers want Kraft to take the food dyes out of its popular Mac and Cheese.
Bloggers Lisa Leake and Vani Hari say the artificial colorings, Yellow 5 and Yellow 6 are not in the company's Macaroni and Cheese in other countries.
The two women say the dyes are banned in those countries and were removed after a consumer outcry.
Leake, who runs the blog 100-Days of Real Food says she and Hari decided to take action.
"We were just alarmed by what we uncovered. Basically, these are American companies using ingredients in our food, as you said, that are not used, and in some cases, banned elsewhere. We decided we needed to do something about it. So we strategically picked Karft Macaroni and Cheese, an iconic American food product, hoping to get our message across, that these artificial dyes, they're not necessary, they're for cosmetic reasons only and they do pose risks and we'd like them to get them out of our food." said Leake.
Leake and Hari started an online petition to remove the harmful additives.
