Contaminants are not always listed ingredients
Lead, arsenic, cadmium and mercury can enter foods through soil, water, processing equipment, packaging or other environmental pathways. They may not appear in an ingredient list because they are not intentionally added ingredients. A barcode scan cannot confirm that a product contains zero contaminants.
Why children need extra care
Children eat more food relative to body size than adults and are still developing. Parents and caregivers can use current public-health guidance, vary foods when practical and pay attention to recalls or official alerts. Individual concerns should be discussed with a pediatric clinician.
Supplements need careful review too
Natural does not mean every supplement has been tested in the same way or is appropriate for every person. Dose, quality, interactions and medical needs matter. HealthLogic can explain listed ingredients but cannot test a product, determine exposure or diagnose harm.
