FoodBench-QA challenges systems to answer food and nutrition questions using evidence from food composition databases and food-related ontologies. The shared task comprises three main tasks: nutrient estimation from recipe ingredients, evaluated using EU Regulation 1169/2011 tolerance thresholds; FSA traffic-light classification for fat, salt, saturates, and sugars; and food named entity recognition and linking to three ontologies, namely Hansard Taxonomy, FoodOn, and SNOMED CT. We received submissions from five participating teams across all tasks. For nutrient estimation, the best system achieved accuracy rates of 93.57{\%} for protein, 86.50{\%} for sugars, 84.65{\%} for fat, and 86.26{\%} for saturates. For FSA traffic-light prediction, the best macro F1 scores ranged from 0.65 to 0.90 across different nutrient-color combinations. For named entity linking, the best systems achieved macro F1 scores between 60.71{\%} and 80.89{\%} for natural text and 87.75{\%} and 95.75{\%} for artificial NEL datasets, depending on the ontology."
