Portfolio reading
Look for consistency across the range
The catalog shows a small but varied range led by Diet Coke With Lime Flavor, Lime; Diet Cola; Cherry Diet Coke. Across 12 tracked products, the mean is 75.9/100 and 100.0% carry a separately flagged ingredient. That is enough to compare formulations inside this captured range, but not enough to assume every current package matches. Start with the lowest-scoring product rows and confirm the ingredient panel when a specific additive matters.

Diet coke relies most on Caramel Coloring, an industry staple
Across the 11 Diet coke products scored here, Caramel Coloring appears in 11. It is used by 3,551 other brands in this database (10.1% of them), so its presence says more about the category than about this brand. A flag records that a named source raised a concern about an ingredient. It is not a finding that a product is unsafe to eat.
| Flagged ingredient | Diet coke products | Why it is flagged |
|---|---|---|
| Caramel Coloring | 11 | Restricted: California (Prop 65 warning for 4-MEI) |
| Aspartame | 10 | Concern recorded by a review body; no ban cited |
| Acesulfame Potassium | 3 | Concern recorded by a review body; no ban cited |
| Sucralose | 1 | Concern recorded by a review body; no ban cited |
Counts are products in this database whose ingredient list names the flagged ingredient. Flags come from FDA enforcement actions, CSPI Chemical Cuisine ratings and US state ingredient laws; see the methodology for how each source is applied.
Visible product sample
Label complexity does not determine the screening result
Each point is one of the 11 concern-sorted Diet coke records shown below. Horizontal position is the number of resolved ingredients on that product's stored label; vertical position is its source-derived screening score. The dashed medians (8 ingredients and 80/100) divide this displayed sample only. A longer label is not automatically worse: open a specific product to inspect its flagged rows and source coverage.
