    Environmental impact of athletes’ diets greenhouse gas emissions, water footprint, and sustainability awareness
    (Springer, 2026-01) Acar, Selva; Tuna, Tuğba; Ersoy, Nesli; 336342
    This cross-sectional study evaluated the environmental impact of athletes’ dietary patterns by estimating greenhouse gas emissions (GHGE) and water footprint (WF). It also assessed knowledge, attitudes, and behaviors related to sustainable nutrition using a structured questionnaire aligned with the FAO definition of sustainable diets. Conducted between January and August 2023 in Ankara, the study included 100 elite athletes (mean age: 21.0 ± 3.3 years; 65% female) from various sports disciplines. Dietary intake was assessed using a semi-quantitative food frequency questionnaire, and GHGE and WF values were calculated based on life cycle assessment data. The mean GHGE and WF values of athletes’ diets were 3017.1 ± 1877.4 g CO₂-eq/day and 5.4 ± 3.2 mL/g, respectively. Male athletes and strength/power athletes exhibited significantly higher dietary environmental impacts than female and team sports athletes (p < 0.001 and p < 0.05, respectively). Red meat and animal protein consumption were strongly associated with higher GHGE and WF values (p < 0.001). Despite the increasing importance of sustainability, more than 90% of participants lacked accurate knowledge of sustainable nutrition. Moreover, a discrepancy was observed between athletes’ stated willingness to support environmental values and their actual food choices, indicating an intention–behavior gap. This study contributes to the limited literature by quantifying the environmental impact of athletes’ diets while concurrently examining sustainability-related behavioral factors. The findings underscore the importance of integrating sustainability principles into sports nutrition planning and education to reduce environmental impacts while maintaining performance goals.

    Future Protein Sources in Sports Nutrition: Sustainable Solutions
    (Springer, 2026-02) Tuna, Tuğba; Ersoy, Nesli; 336342
    Purpose of ReviewThis review evaluates the potential of alternative protein sources, including plant-based proteins, insect proteins, mycoproteins, microalgae, and cultured meat, in meeting the increasing demand for sustainable and functional protein solutions in sports nutrition.Recent FindingsStudies indicate that alternative protein sources provide significant environmental benefits, such as reduced greenhouse gas emissions and lower water use, while delivering essential nutrients to support athletic performance and recovery. Advances in technology and production methods have further enhanced their feasibility as replacements for conventional animal-based proteins.SummaryIntegrating alternative protein sources into sports nutrition offers a dual benefit: meeting athletes' dietary requirements and supporting global sustainability goals. These protein sources pave the way for innovative, environmentally conscious dietary practices in sports nutrition, marking a pivotal shift toward a more sustainable future.
