Generational perspectives on sustainable diets in Saudi Arabia: implications for food security and behavioral change.
Article in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 and objectives: Sustainable healthy diets (SHDs) are pivotal for promoting public health while mitigating environmental impacts. However, the adoption of sustainable and healthy eating behaviors (SHEBs) varies across demographic groups, particularly generations. This study assessed generational differences in SHEBs, protein consumption patterns, motivations for dietary change, and readiness to adopt plant-based diets in Saudi Arabia, a nation undergoing rapid urbanization and dietary transitions. Methods: A cross-sectional online survey of 637 Saudi adults from Generations Z, Y, and X was conducted between November 2023 and March 2024. SHEBs were measured using a validated scale covering balanced diets, local food choices, meat reduction, food waste, and quality labels. Protein intake (animal- vs. plant-based), BMI, motivations for adopting SHDs, and stages of behavioral change were analyzed across generations using ANOVA, chi-square tests, and regression models. Results: Generation X exhibited the highest SHEBs scores, driven by quality-labeled food choices and reduced meat consumption. Generation Y showed moderate SHEBs engagement, motivated by ethical and environmental concerns. Generation Z reported the lowest SHEBs scores, with health and weight loss as primary motivators, but also the highest animal-protein intake. Across all generations, plant-based protein intake was a significant predictor of greater SHEBs adherence. However, over 80% of participants remained in the pre-contemplation or contemplation stages for adopting plant-based diets, highlighting behavioral resistance to change. Conclusion: Generational differences in dietary behaviors underscore the need for customized, generation-sensitive interventions to promote SHDs in Saudi Arabia. Enhancing awareness, addressing barriers to plant-based eating, and leveraging key motivators such as health and accessibility are essential steps toward transforming food systems for greater sustainability. These insights hold significant implications for developing generation-sensitive strategies that promote SHDs, improve nutritional outcomes, and strengthen food security in Saudi Arabia.
