Dietary intake was assessed using an expanded semi-quantitative food-frequency questionnaire and processed using Nutritics. The analyses included total fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3 and omega-6 fatty acids, trans fatty acids, and individual fatty acids including linoleic acid, alpha-linolenic acid, arachidonic acid, EPA, DPA and DHA. Nutritionally relevant indicators and food-source contributions were also examined.</p><p dir="ltr">The public package contains aggregated results supporting the main and supplementary tables and figures, aggregated food-source contribution data, methodological inputs, R analysis code, quality-assurance documentation and information required to interpret the analytical workflow.</p><p dir="ltr">Participant-level dietary records, participant identifiers, raw FFQ and Nutritics/Access source files, participant × FoodName records, detailed FoodName-level dietary contributions, and complete food-composition crosswalks are not included in this public repository. These exclusions protect participant confidentiality and prevent disclosure of participant-level information beyond that required to support the reported study.</p><p dir="ltr">Some R scripts therefore require non-public source data and are provided to document the analytical procedures and enhance methodological transparency rather than as a fully executable public participant-level dataset.</p> 2026-09-29T11:51:52Z Dataset Dataset 10.6084/m9.figshare.34023501.v1 https://figshare.com/articles/dataset/Aggregate_Data_and_R_Analysis_Code_for_Dietary_Fatty-Acid_Quality_in_Emerging_Adulthood_Omega-3_Omega-6_and_Food_Sources_in_UK_University_Students_/34023501 CC BY 4.0
