Corn-Based Sweeteners (Corn Syrup): HFCS is a hallmark of ultra-processed foods.
Modified Starches (Modified Cornstarch): Chemical modification is a hallmark of UPF.
Processed Meats (Gelatin): Mechanically separated and reformed meats are UPF markers.
Artificial Colors (Yellow 5, Red 40, Blue 1, +1 more): Synthetic colors are definitive UPF markers.
