Whether physical activity can offset the health risks of a pro-inflammatory diet is a compelling question, but it becomes conceptually misleading when interpreted as simple behavioral compensation. This narrative review integrates evidence on dietary inflammatory potential, movement-related physiological capacity, and chronic disease vulnerability, with particular attention to the Dietary Inflammatory Index, biological translation pathways, and emerging joint diet–activity evidence. Pro-inflammatory dietary exposure may be translated into disease vulnerability through immune activation, oxidative stress, adipose tissue inflammation, metabolic dysfunction, endothelial impairment, and gut-related inflammatory signaling. Habitual movement and exercise training may influence many of these same pathways through skeletal muscle signaling, improved insulin sensitivity, reduced visceral adiposity, redox adaptation, vascular regulation, and higher cardiorespiratory fitness. Taken together, current human evidence is more consistent with partial buffering and joint risk stratification than with full compensation. We therefore propose an Inflammatory Resilience Framework in which physical activity, cardiorespiratory fitness, skeletal muscle function, adiposity, metabolic flexibility, vascular function, and baseline health status are positioned as modifiers of the biological translation from dietary inflammatory exposure to disease vulnerability. This framework shifts the research question from whether exercise cancels dietary risk to how movement-related physiological capacity modifies inflammatory risk expression across individuals, pathways, and outcomes.

Exercise-induced reactive oxygen and nitrogen species (RONS) serve as crucial signaling molecules for training adaptation, mitochondrial biogenesis, and inflammatory resolution, rather than being mere markers of oxidative damage. Chronic or excessive high-dose antioxidant supplementation may suppress these vital redox-sensitive pathways. Consequently, this narrative review examines food-based antioxidant strategies as approaches for redox modulation, meaning support for recovery and redox homeostasis without indiscriminately suppressing exercise-induced redox signals that may contribute to training adaptation, while emphasizing the distinction between whole-food matrices and isolated supplements. A structured literature search was conducted across major electronic databases, including PubMed, Web of Science, Scopus, and SPORTDiscus. The search focused on intersecting themes of exercise physiology, redox biology, and sports nutrition. The reviewed evidence includes short-term human intervention studies, systematic reviews, meta-analyses, and mechanistic studies examining tart cherry, berries, pomegranate, cocoa, green tea, beetroot, extra virgin olive oil, and Mediterranean-style dietary patterns. Overall, the evidence suggests that these food-based strategies may influence recovery-related outcomes through mechanisms extending beyond direct radical scavenging, including inflammatory regulation, vascular function, and gut-derived metabolism; however, the strength and consistency of findings vary by food source, outcome, dose, timing, study population, dietary matrix, and bioavailability. Current literature does not support universal, fixed daily antioxidant use. Food-based strategies appear most appropriate during periods of elevated recovery demands, such as heavy training blocks, congested competition, muscle damage, or environmental stress. Food-based antioxidant nutrition should therefore be interpreted as a conceptual, evidence-informed approach to periodized and context-specific recovery support, rather than as a universal or evidence-graded guideline, because much of the available evidence derives from short-term and heterogeneous intervention studies. These strategies should complement foundational sports nutrition practices (energy availability, macronutrient distribution, hydration, and sleep) when balancing the preservation of long-term training adaptations with the need for acute recovery.

How physical activity may modify the health consequences of a pro-inflammatory diet remains an important but unresolved question. This hypothesis-generating narrative review examines this question by integrating evidence on dietary inflammatory potential, physical activity, physiological capacity, and inflammation-related health outcomes, and by proposing an Inflammatory Resilience Framework to guide future research. Current evidence strongly supports systemic inflammation, adiposity, insulin resistance, and vascular dysfunction as relevant pathways linking dietary inflammatory exposure to disease vulnerability, while redox- and gut-related mechanisms remain more indirect. Physical activity and higher physiological capacity may influence several of these pathways through metabolic, vascular, muscular, and inflammatory regulation. Preliminary human joint-association evidence suggests that physical activity may partially attenuate selected consequences of pro-inflammatory dietary exposure, but it does not establish a consistent modifying effect or full compensation. The proposed framework positions physical activity, cardiorespiratory fitness, skeletal muscle function, adiposity, metabolic flexibility, vascular function, and baseline health status as factors that may modify the association between dietary inflammatory exposure and disease vulnerability. Rather than asking whether exercise cancels dietary risk, the framework provides a testable structure for future studies integrating objective physical activity, fitness, physiological reserve, inflammatory and metabolic markers, and longitudinal interaction analyses to determine when, how, and in whom physical activity modifies diet-related inflammatory risk.
