The Impact of Diet on Long-Term Oncological Outcomes: Investigating Nutritional Mechanisms in Cancer Prevention Management and Prognosis
Abstract
Long-term oncological outcomes are significantly influenced by dietary patterns and nutritional status. Emerging evidence suggests that specific nutrients and dietary behaviors modulate the biological pathways involved in cancer initiation, progression, and therapeutic response. Understanding these nutritional mechanisms is essential for optimizing cancer prevention strategies, improving treatment efficacy, and enhancing long-term prognosis. Dieting is a modifiable factor influencing cancer prevention, progression, and survivorship. This review is a molecular, clinical, and epidemiological data amalgamation that aims to figure out the first of the three aspects, i.e., how dietary patterns and nutrients affect carcinogenesis, therapeutic tolerance, and long-term outcomes in long-term oncology. The current review moves from diet-dependent core cancer mechanisms that lead cancer pathways through metabolic reprogramming, inflammation, oxidative stress regulation, and epigenetic alterations. Protective dietary patterns, e.g., plant-based, Mediterranean-style, fiber-rich, and omega-3-fed diets, typically provide lower oxidative and inflammatory loads while also facilitating immune surveillance and metabolic stability. Therapy-personalized nutrition that is high in energy-protein and functional foods is instrumental to treatment tolerance, reduction in complication incidence, and cachexia relief. The newest research highlights the significant influence of epigenetic remodeling and…
