Two food bloggers have targeted the food coloring in Kraft Dinner, starting a campaign to remove it from the popular macaroni in a box.
Lisa Leake, and Vani Hari launched a Change.org petition this week and already have 150,000 signatures.
The bloggers point out that in other countries, Kraft Dinner does not contain the dyes, reserving them only for an American audience which demands the deep yellows in their meal.
The women show a taste test on Youtube with the UK version without the dyes and claim they taste and look exactly the same (see video below).
According to ABC News, the women say the yellow dye is only for "aesthetic purposes."
