How to use this page

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 Yellow 5 as the trigger. Open records such as 0016500579793; 1 Wow!, Lollipop Bouquet; 1/2 Marble Grad Cake With Red Borders and inspect which ingredient row carries the caution marker. The 23.5/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 80% 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 19544 of 19559 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 Yellow 5

Across the 19,566 products on this site that list Yellow 5, 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. Blue 1 shows up about 13.6x more often with Yellow 5 than in the catalogue at large.

Yellow 5 — common follow-ups

How should I read safety signals when Yellow 5 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 Yellow 5 is the trigger. Where a source rating exists, Yellow 5 scores 1/5 on this site's screening scale and CSPI lists it as "Avoid" with FDA SAFFA status "Approved (certified color)". None of that replaces a product-, dose-, allergy-, or person-specific determination.

Which product shelves show up most often with Yellow 5?

Yellow 5 ranks in the top decile by product count (#47 of 247,206), appearing in 19,566 indexed products led by Snacks. The sample list below is a slice of that footprint, not the full universe.

Why is Yellow 5 so common on ingredient lists?

The source record does not name a technical effect, yet Yellow 5 appears in 19,566 products (#47 usage rank). High prevalence here describes formulation frequency, not an approved use level.
