Ultra-Processed Diets and Endocrine Disruption, Explanation of Missing Link in Rising Cancer Incidence Among Young Adults
Simple Summary The alarming rise in early-onset cancers among adolescents and young adults parallels the global surge in ultra-processed food (UPF) consumption. Beyond poor nutrition, UPFs act as “Trojan horses,” introducing biologically active compounds, particularly endocrine-disrupting chemicals (EDCs), that interfere with hormonal regulation, immune responses, and microbial balance. These exposures, often occurring during vulnerable developmental stages, disrupt endocrine signalling; promote chronic, low-grade inflammation; alter the gut microbiota; and induce epigenetic changes, thereby creating a permissive environment for carcinogenesis. Key EDCs migrate from packaging into foods, while additives and high-temperature processing further compound the risk. This review integrates emerging evidence across disciplines to highlight UPFs as silent but systemic disruptors of metabolic and genetic homeostasis. The “Trojan horse” model reframes UPFs as long-term, multifactorial risk factors, underscoring the need for multi-omics research and personalised dietary strategies to assess and mitigate cancer risks in younger populations.
