Key findings
- 1Boxed mac and cheese powder is dairy fractionation in reverse; cheese broken into components and reassembled with additives
- 2The yellow color in many standard boxes comes from synthetic dyes, not from cheese
- 3Homemade mac and cheese with real cheese, butter, and milk uses a handful of recognizable ingredients and far less processing than a boxed powder
Why is Mac and Cheese ultra-processed on average?
Boxed mac and cheese pairs simple dried pasta with a cheese powder. In most boxes that powder is built from dairy fractions such as whey protein concentrate, milk protein concentrate and milkfat, recombined with sodium phosphate (an emulsifier), sodium alginate (a thickener) and citric acid. Many standard boxes get their color from synthetic dyes (Yellow 5 and Yellow 6, also called tartrazine and sunset yellow); others use annatto, paprika or turmeric. In effect, cheese is broken into its components and reassembled with additives so that it behaves like a sauce. In our analysis, boxed mac and cheese averages a Processing Score of 9.6, which is Level 4.

Frequently asked questions
Is boxed mac and cheese ultra-processed?
In our analysis, boxed mac and cheese averages a Processing Score of 9.6, which is Level 4. The cheese powder typically contains whey protein concentrate, milkfat, sodium phosphates and emulsifiers, and many boxes add synthetic dyes.
Are some boxed brands less processed than others?
Often, yes. Boxes colored with annatto or paprika instead of synthetic dyes, and with fewer emulsifiers, tend to score lower. Compare the ingredient lists, or search a brand to see its own score.
Is homemade mac and cheese ultra-processed?
No. Mac and cheese made with pasta, real cheese, butter, and milk uses a handful of recognizable ingredients. The processing classification depends on the ingredients, not the dish concept.
Why is boxed mac and cheese so yellow?
Many standard boxes use Yellow 5 (tartrazine) and Yellow 6 (sunset yellow), synthetic dyes. Real melted cheese is pale yellow to orange depending on the cheese type, never the bright neon yellow of a dyed powder.
