Summary

Kit Kat scores 20/100 — the cleanest mass-market candy on this list. Third-party 2025 testing detected 230 ppb arsenic. Free of petroleum dyes and hydrogenated oils, but still contains refined palm kernel oil, PGPR synthetic emulsifier, and artificial flavor. Lower processing burden than most competitors but still ultra-processed. Distributed in the US by The Hershey Company under license from Nestlé.

Arsenic

230 ppb

High

Detected at a high level — at or above health-based exposure limits. Regular exposure at this level is a genuine health concern. No safe level of arsenic exposure exists; chronic exposure is linked to increased cancer risk (lung, skin, kidney, bladder), cardiovascular disease, and neurodevelopmental harm in children.

Independent third-party testing detected arsenic at 230 parts per billion — a notable contamination level.
