    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.

    The role of nutrition and nutritional supplements in the prevention and treatment of malnutrition in chronic obstructive pulmonary disease: current approaches in nutrition therapy
    (Springer, 2025-01) Tuna, Tuğba; Samur, Gülhan; 336342
    Purpose of Review Malnutrition is a significant comorbidity in Chronic Obstructive Pulmonary Disease (COPD), contributing to disease progression and reduced quality of life. This narrative review examines the role of nutritional therapy in the prevention and management of malnutrition in COPD, emphasizing evidence-based approaches and their clinical implications. Recent Findings COPD patients face increased metabolic demands, systemic inflammation, and reduced dietary intake, resulting in muscle wasting, sarcopenia, and cachexia. Recent evidence highlights the efficacy of targeted nutritional strategies, including essential amino acid supplementation, omega-3 fatty acids, vitamin D, and antioxidants, in improving respiratory function, muscle strength, and patient well-being. Comprehensive nutritional assessments and personalized interventions are increasingly recognized as critical components of COPD care. However, long-term efficacy data remain limited. Summary Nutritional therapy plays a pivotal role in managing malnutrition and improving clinical outcomes in COPD. This review synthesizes the latest evidence, identifies gaps in current research, and proposes strategies for integrating personalized nutrition into COPD care. Future studies are needed to establish the long-term benefits of these interventions and to develop tailored nutritional guidelines for COPD patients.
