What research says

Animal and lab studies only

  • Concern

    DNA damage in cells1

    In lab and plant studies, Quinoline yellow showed genotoxic effects, meaning it damaged DNA.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted. This page is a reference, not medical advice. It describes what regulators and published research say. Talk to a doctor or dietitian about your own diet.

What expert reviews concluded
