However, iron deficiency is a common problem in athletes, especially endurance athletes, due to factors such as increased iron loss due to exercise-induced sweating, hematuria, and gastrointestinal bleeding. Exercise induces hematological adaptations due to increased demand of oxygen transport as well as inflammation, which reduces the ability to absorb iron post-exercise. Iron deficiency can lead to fatigue, reduced performance, poorer recovery and increased susceptibility to infections. Iron absorption is tightly regulated to prevent toxicity, with hepcidin playing a central role. Elevated hepcidin levels, which are influenced by exercise-induced inflammation and circadian rhythms, can significantly reduce iron absorption. In addition, the bioavailability of dietary iron varies, with heme iron from animal products being more readily absorbed than non-heme iron from plant sources. Athletes on a vegetarian or vegan diet may require increased iron intake to meet their needs. Monitoring iron status through regular blood tests, including serum ferritin and hemoglobin levels, is critical for early detection and treatment of iron deficiency. Strategies to improve iron absorption include consuming iron-rich foods with promoters such as vitamin C, while inhibitors such as phytates and calcium should be avoided. In cases of significant deficiency, supplementation under medical supervision may be necessary. Understanding these factors and using appropriate nutritional and monitoring practices can help athletes maintain optimal iron levels and overall performance.

This includes constructing and maintaining sports facilities, athlete mobility, and waste generation at large events. Fur-thermore, athletes are often characterized by unsustainable dietary practices due to increased caloric intake, high protein intake, and dietary supplement consumption. Purpose: This narrative review aims to explore the role of athletes as frontrunners in promoting sustainable practices, particularly in their dietary choices, and to assess the potential environmental benefits of adopting more sustainable nutrition habits in sports. Main outcomes: The sports sector contributes significantly to greenhouse gas emissions, particularly through high energy consumption and waste production. Sustainable dietary changes, such as reducing consumption of animal products, can significantly lower the ecological footprint of athletes. Athletes may, as role models, influence public behavior towards more sustainable nutrition practices. Approaches to combine sustainable nutrition with key factors of sports nutrition regarding energy and nutrient intake could support health and performance of athletes. However, it might be challenging for athletes with poor food literacy. Conclusion: Promoting sustainable nutrition among athletes benefits the environment and may also support athletes in achieving their training goals due to well-balanced diets. Further research is needed to fully understand the long-term impacts of these dietary changes on athletic performance.
