Children and adolescents in this pattern had significantly higher intakes of energy and carbohydrates but lower protein intake compared with those consuming predominantly home-prepared foods. Among adults and the elderly, this pattern was associated with higher intakes of energy, saturated fats, trans fats and free sugars and lower fibre intake. Additionally, children and adolescents whose diets predominantly included food prepared away-from-home showed a decrease in HES (<jats:italic>\u03b2<\/jats:italic> = \u20130\u00b77, 95 % CI = \u20131\u00b73, \u20130\u00b72), and adults experienced a greater reduction (<jats:italic>\u03b2<\/jats:italic> = \u20131\u00b72, 95 % CI = \u20131\u00b75, \u20130\u00b79).<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S1368980025100712_as6\">\n\t    <jats:title>Conclusions:<\/jats:title>\n\t    <jats:p>In Portugal, consuming food prepared away from home is associated with poorer dietary quality, with higher energy and unhealthy nutrient intake and lower HES, suggesting a need for interventions focused on promoting healthier food preparation practices.<\/jats:p>\n\t  <\/jats:sec>","DOI":"10.1017\/s1368980025100712","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T03:42:56Z","timestamp":1752810176000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Dietary intake according to different patterns of food preparation in children and adults: results from the Portuguese National Food, Nutrition and Physical Activity Survey (IAN-AF 2015\/2016)"],"prefix":"10.1017","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8945-3708","authenticated-orcid":false,"given":"Mariana","family":"Rei","sequence":"first","affiliation":[{"name":"University of Porto"},{"name":"University of Porto"},{"name":"University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8886-3211","authenticated-orcid":false,"given":"Daniela","family":"Correia","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"University of Porto"},{"name":"University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8960-2160","authenticated-orcid":false,"given":"Duarte","family":"Torres","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"University of Porto"},{"name":"University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1524-852X","authenticated-orcid":false,"given":"Carla","family":"Lopes","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"University of Porto"},{"name":"University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6443-8229","authenticated-orcid":false,"given":"Ana Isabel A.","family":"Costa","sequence":"additional","affiliation":[{"name":"Portuguese Catholic University"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0647-5018","authenticated-orcid":false,"given":"Sara SP","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"University of Porto"},{"name":"University of Porto"}]}],"member":"56","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"S1368980025100712_ref29","doi-asserted-by":"publisher","DOI":"10.1079\/PHN2004701"},{"key":"S1368980025100712_ref22","doi-asserted-by":"publisher","DOI":"10.1017\/S1368980014001943"},{"key":"S1368980025100712_ref19","doi-asserted-by":"publisher","DOI":"10.1186\/s12937-017-0281-2"},{"key":"S1368980025100712_ref23","doi-asserted-by":"publisher","DOI":"10.1017\/S1368980019003549"},{"key":"S1368980025100712_ref12","doi-asserted-by":"publisher","DOI":"10.1017\/S1368980007000171"},{"key":"S1368980025100712_ref36","volume-title":"R: A Language and Environment for Statistical Computing.
