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”

<p dir="ltr">This repository contains aggregated data, analytical outputs, methodological documentation and R code supporting the study “Dietary Fatty-Acid Quality in Emerging Adulthood: Omega-3, Omega-6 and Food Sources in UK University Students”.</p><p dir="ltr">The study characterised dietary fatty-acid intake in 111 young adults aged 18–22 years attending a UK university. 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.
