Frequently asked questions

Is skim milk more processed than whole milk?

Barely. Skim milk adds one mechanical step, separating the fat by centrifuge, and no ingredients. Both plain milks sit at the low end of our processing scale; flavored milks score higher because of added sugar and stabilizers.

Why do some milk products score higher than others?

Added vitamins are standard and barely move the score in our analysis. The bigger jumps come from flavored varieties and shelf-stable formulations with added stabilizers or sweeteners.
