The Oxford WebQ questionnaire is a web-based 24 h dietary assessment tool developed for repeated administration in large prospective studies and obtains information on the quantities of up to 206 types of foods and 32 types of drinks consumed over the previous day (Liu et al., Public Health Nutr, 2011). Oxford WebQ questionnaire nutrient calculation has been updated recently following the introduction of the UK Nutrient Databank as its new food composition table (Perez‑Cornago et al., Eur J Nutr, 2021)
