What this page can and cannot answer
Audit the co-occurring flags first
100% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Blue# 2 as the trigger. Open records such as World food products, choco-nut trail mix and inspect which ingredient row carries the caution marker. The 60.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 53% average label depth helps locate the term when checking the package.
100% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 1 of 1 NOVA-tagged records. That describes the surrounding products, not the substance. For a useful comparison, hold category and processing level constant, then inspect which named component changes alongside the caution flag; otherwise the product mix will confound the ingredient question.
Next check: open the lowest-scoring linked formulation and locate the exact caution-marked component.
