Of the way down the captured list, averaged across the 152 products listing it (mean slot 5.7). Trans Fat usually falls in the upper half of the list; this position does not measure its amount because source formatting, compound ingredients and labeling exceptions vary.

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 Trans Fat as the trigger. Open records such as 4F Gummy Dinosaur; Absopure Purified Water; Apple Banana With Mixed Cereal (Sitter) and inspect which ingredient row carries the caution marker. The 61.9/100 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.

100% of linked products contain a separately flagged ingredient

Processing is unusually concentrated here: Group 4 accounts for 98 of 107 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.

What else is usually in the same product as Trans Fat

Across the 152 products on this site that list Trans Fat, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set. Sucralose shows up about 5.1x more often with Trans Fat than in the catalogue at large.

Questions readers ask about Trans Fat

How should I read safety signals when Trans Fat sits in heavily flagged products?

100% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Trans Fat is the trigger. Where a source rating exists, Trans Fat scores 1/5 on this site's screening scale and CSPI lists it as "Avoid" with FDA SAFFA status "Banned (FDA, 2018)". None of that replaces a product-, dose-, allergy-, or person-specific determination.

Which product shelves show up most often with Trans Fat?

Trans Fat ranks in the top decile by product count (#2,346 of 247,206), appearing in 152 indexed products led by Beverages and beverages preparations. The sample list below is a slice of that footprint, not the full universe.

What function does Trans Fat serve when it appears beside other flagged additives?

Trans Fat is recorded as a other in source technical-effect fields. In high co-flag products, that function coexists with other caution-marked components — inspect the full list rather than isolating this role.
