    The global prevalence of obesity has risen to epidemic proportions, posing significant health challenges across populations and contributing to increased morbidity and mortality from non-communicable diseases. Among its many consequences, obesity is now firmly established as a modifiable risk factor for breast cancer, particularly in postmenopausal women. The association between obesity and breast cancer is driven by complex and interrelated biological mechanisms, including chronic low-grade inflammation, hormonal imbalances, adipokine dysregulation, insulin resistance, and metabolic dysfunction. These factors collectively create a pro-tumorigenic environment that supports cancer initiation, progression, and recurrence. This review explores the multifaceted nexus between obesity and breast cancer, emphasizing the critical role of inflammatory, hormonal, and metabolic pathways in mediating disease risk and outcomes. Additionally, it highlights the emerging contribution of gut microbiome dysbiosis in modulating host immunity and systemic inflammation in the context of obesity. Nutritional strategies—ranging from dietary pattern modification to caloric restriction and time-restricted feeding (TRF)—are examined for their potential to reduce risk, enhance treatment efficacy, and improve survivorship in breast cancer patients.

    Oesophageal adenocarcinoma (EAC) is increasingly associated with obesity, metabolic dysfunction, and genetic predispositions. This review explores how nutritional factors interact with these risk elements, emphasizing the potential of dietary strategies in EAC prevention and management. Diets such as the Mediterranean and plant-based patterns may reduce inflammation, oxidative stress, and metabolic imbalance, thereby modulating cancer risk. Nutrient-rich foods–particularly omega-3 fatty acids, cruciferous vegetables, and dietary fibre–offer additional protective effects. Personalized nutrition, tailored to individual genetic and metabolic profiles, is emerging as a promising tool in cancer prevention. Moreover, weight management strategies like caloric restriction and intermittent fasting may contribute to risk reduction. Integrating these approaches into clinical and public health practices could play a critical role in mitigating the underlying drivers of EAC. Further research is needed to strengthen dietary guidelines and advance precision nutrition for high-risk populations.

    Psoriasis is a chronic immune-mediated skin disease characterized by cytokine dysregulation. Pro-inflammatory mediators, including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-17, and IL-23, play pivotal roles in the pathogenesis of psoriasis. Emerging evidence suggests that dietary interventions can modulate cytokine activity, providing a complementary approach to standard therapies. This narrative review examines the impact of various dietary strategies, including a Mediterranean diet, ketogenic diet, gluten-free diet, and fasting-mimicking diet, on cytokine profiles and clinical outcomes in psoriasis. Research insights reveal that dietary components such as omega-3 fatty acids, polyphenols, and short-chain fatty acids influence immune signaling pathways. These pathways include nuclear factor-kappa B (NF-κB) and Signal Transducer and Activator of Transcription 3 (STAT3). Additionally, these dietary components promote anti-inflammatory effects mediated by gut microbiota. Clinical studies demonstrate significant reductions in psoriasis severity, improved quality of life, and modulation of key cytokines associated with disease activity. Despite these advancements, significant challenges persist in effectively integrating these findings into clinical practice. These challenges include variability in patient responses, adherence issues, and the need for robust biomarkers to monitor efficacy. Future directions emphasize the potential of personalized nutrition and precision medicine approaches to optimize dietary interventions tailored to individual cytokine profiles and genetic predispositions. Integrating these strategies into psoriasis care could transform treatment paradigms by simultaneously addressing both systemic inflammation and comorbid conditions.
