Last April, Kraft announced it was removing artificial flavors, dyes and preservatives from its mac and cheese. The company said today it has sold 80 million boxes of the stuff since the new ingredients were introduced in December. This month, the company started a marketing campaign, including the promotion of the hashtag "#didntnotice"
The company's mac and cheese is now made with paprika, annatto and turmeric instead of artificial dyes yellow 5 and yellow 6. That change has been listed on the box for the past few months, the company said.
