Balancing Environmental Footprints and Nutritional Efficiency in University Canteen Menus: A Scenario-Based Life Cycle Assessment of Menu Architecture.
Article in Foods (Basel, Switzerland), 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
University canteen menus are increasingly evaluated for their environmental impacts, yet sustainability strategies often focus on single-food substitutions rather than on overall meal structure. This study investigated whether environmental improvements are better achieved through main-dish substitution or through redesigning menu architecture while maintaining nutritional efficiency. An LCA-based dataset of university canteen meals was restructured into a fixed four-course architecture, and four representative scenarios were evaluated for energy, protein, carbon, and water footprints, as well as the protein-adjusted carbon footprint. This was followed by a Monte Carlo simulation (10,000 iterations per scenario) using the observed annual menu dataset. Main-dish substitution reduced the carbon footprint by 27.3% (from 2.355 to 1.713 kg CO
