Why Does This Score Ultra-Processed?

In our analysis, Diet Soda scores Ultra-Processed. That classification is shaped by ingredients commonly associated with ultra-processed foods:

Artificial Sweeteners (Aspartame): Synthetic sweeteners are definitive UPF markers.
Artificial Colors (Yellow 5 And Erythorbic Acid (Preserves Freshness)): Synthetic colors are definitive UPF markers.
Stabilizers & Gums (Citrus Pectin, Gum Arabic): Industrial stabilizers common in UPF.
Other Additives (Caffeine): Miscellaneous additives generally indicate processing.
Natural Flavors (Natural Flavors): Despite being natural, these are highly processed extracts.

Within Soda, this product is more processed than about 64% of the 6,804 products we've analyzed.

Processing classification reflects ingredient and additive analysis, not a judgment of any product's safety, quality, or healthfulness.
