Sustainable nutrition and athlete well-being: associations with psychological and physical performance indicators.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Sustainable dietary practices are increasingly recognized for their potential relevance to both environmental sustainability and athlete health. However, limited research has examined the relationship between sustainable nutrition behaviors and psychological and physical performance indicators among athletes. Objective: This study aimed to examine the associations between sustainable food and diet choices, sports psychology outcomes, and perceived physical performance indicators among physically active individuals. Methods: A quantitative cross-sectional study was conducted among 250 physically active participants recruited from sports clubs, university teams, fitness centers, and training groups. Data were collected using a structured questionnaire assessing sustainable dietary practices, psychological outcomes (motivation, mental focus, mood stability, and psychological readiness), and perceived physical outcomes (energy level, recovery quality, fatigue control, and perceived performance). Descriptive statistics, Pearson correlation analysis, and multiple regression analysis were performed to evaluate associations among study variables. Results: Participants reported moderate-to-high levels of sustainable dietary practices (mean = 3.76 ± 0.61). Sustainable diet choices were positively associated with sports psychology outcomes ( Conclusion: The findings suggest that sustainable dietary practices are associated with more favorable psychological well-being and perceived physical performance indicators among athletes. Although causal relationships cannot be established due to the cross-sectional design, the results highlight the potential relevance of sustainable nutrition within athlete health and performance contexts. Future longitudinal and experimental studies are needed to confirm these relationships and examine underlying mechanisms.
