What this page can and cannot answer
Audit the co-occurring flags first
50% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Thiamine B1 as the trigger. Open records such as Guarina Leche; Jamon and inspect which ingredient row carries the caution marker. The 55.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 27% average label depth helps locate the term when checking the package.
50% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 2 of 2 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.
