Food preservatives and child health: Mechanisms, clinical concerns, and safe consumption practices for modern families

Processed and packaged foods have become integral to modern dietary patterns, especially among children. Food preservatives used to enhance shelf-life, prevent spoilage, and maintain product quality carry potential biological effects that raise increasing concern. Children are physiologically more vulnerable to chemical exposures due to their developing organ systems, higher metabolic rate, and lower body weight. This review evaluates the types and mechanisms of commonly used food preservatives, summarises their potential impacts on child health, highlights evidence from toxicological and clinical studies, and provides practical guidelines for parents and clinicians. The article also examines regulatory standards, acceptable daily intake (ADI) limits, and the cumulative exposure risk in children. Finally, it outlines safe consumption practices and future strategies for reducing preservative-related risks within families and communities.
