Food-based antioxidant strategies for sport 🫐

A new evidence-informed framework.

Food-Based Antioxidant Nutrition for Exercise Recovery and Training Adaptation: A Narrative Review and Conceptual Framework for Redox Signaling, Dietary Matrices, and Periodized Application

Study Details

This new review paper proposed a conceptual, evidence-informed approach to periodised and context-specific food-based antioxidant use in sport 📝

Here is the framework ⬇️

Key Findings

Adaptation-focused endurance training 🏃‍♂️

🎯 Preserving mitochondrial and redox-sensitive signalling

🥗 Diverse diet rich in fruit, vegetables, whole grains, legumes, nuts and seeds

🧬 Supports redox balance and micronutrient sufficiency without suppressing training signals

⚠️ Avoid routine high-dose vitamin C or E supplements unless clinically indicated

Heavy training blocks 🏋️

🎯 Fatigue, inflammation, muscle soreness and incomplete recovery

🥗 Increase berries, tart cherry, pomegranate and other colourful fruits

🧬 May regulate inflammation, oxidative stress and soreness

⚠️ Use these foods to support, not replace, load management, adequate fuelling, protein and sleep

Congested competition periods 📅

🎯 Rapid recovery between repeated events

🥗 Tart cherry, pomegranate, nitrate-rich vegetables, fruit-based recovery meals and snacks

🧬 May reduce soreness, support vascular function and maintain readiness

⚠️ Short-term targeted use is more appropriate than constant daily supplementation

Resistance or eccentric exercise blocks 💪

🎯 Muscle damage, delayed-onset soreness and temporary strength loss

🥗 Tart cherry, berries, pomegranate, protein-rich meals and colourful vegetables

🧬 May support inflammatory resolution, redox balance and muscle repair

⚠️ Avoid excessive antioxidant supplementation when strength or hypertrophy adaptation is the priority

High-intensity, intermittent or team-sport training ⚡

🎯 Repeated-sprint stress, neuromuscular fatigue and limited recovery

🥗 Mixed meals containing fruit, vegetables, nitrate-rich foods, cocoa and adequate carbohydrate

🧬 Supports glycogen restoration, vascular function, redox balance and immune regulation

⚠️ Antioxidant-rich foods should complement, not replace, carbohydrate recovery and hydration

Heat stress or environmental strain ☀️

🎯 Dehydration, electrolyte loss, cardiovascular strain and oxidative stress

🥗 Fluids, electrolytes, fruit, vegetables and high-water, polyphenol-rich foods

🧬 Supports hydration, thermoregulation, vascular function and redox regulation

⚠️ Antioxidants cannot compensate for inadequate fluids, electrolytes or cooling strategies

Older adults undertaking exercise 👴

🎯 Low-grade inflammation, anabolic resistance and slower recovery

🥗 Mediterranean-style meals with protein, polyphenol-rich foods, nitrate-rich vegetables and extra virgin olive oil

🧬 Supports muscle remodelling, vascular health, inflammatory balance and diet quality

⚠️ Prioritise adequate energy, protein, vitamin D and resistance training before concentrated products

Low dietary quality or restricted food variety 🥦

🎯 Low micronutrient and polyphenol intake with impaired recovery

🥗 Increase fruit, vegetables, legumes, nuts, seeds, tea and whole grains

🧬 Improves diet quality, antioxidant defence, gut health and recovery capacity

⚠️ Correct the overall diet before adding supplements

Travel or tournament settings ✈️

🎯 Irregular meals, sleep disruption, inflammation and gastrointestinal challenges

🥗 Portable fruit, berries, tart cherry products, nuts, cocoa-based foods and nitrate-rich options

🧬 Maintains diet quality and provides practical recovery support

⚠️ Choose familiar foods and only use concentrated products that have already been well tolerated

Return from illness or high cumulative fatigue 🤒

🎯 Immune strain, persistent fatigue and reduced training tolerance

🥗 Mediterranean-style meals, colourful fruit and vegetables, protein-rich foods and adequate fluids

🧬 Supports immune regulation, inflammatory resolution and gradual recovery

⚠️ Training reduction or medical assessment may be needed, while concentrated products should be individualised
