OBJECTIVE: We investigated the effects on food and energy intakes of varying the portion size and energy density of a vegetable that was added to a meal or substituted for other foods. DESIGN: In 2 experiments with crossover designs, men and women were served a meal of a vegetable, grain, and meat. Across the meals, the vegetable was served in 3 portion sizes (180, 270, or 360 g) and 2 energy densities (0.8 or 0.4 kcal\/g) by altering the type and amount of added fat. In the addition study (n = 49), as the vegetable portion was increased, amounts of the grain and meat were unchanged, whereas in the substitution study (n = 48), amounts of the grain and meat decreased equally. RESULTS: An increase in the vegetable portion size resulted in greater vegetable consumption in both studies (mean +\/- SE: 60 +\/- 5 g; P &lt; 0.0001). The addition of more of the vegetable did not significantly affect meal energy intake, whereas substitution of the vegetable for the grain and meat decreased meal energy intake (40 +\/- 10 kcal; P &lt; 0.0001). A reduction in vegetable energy density decreased meal energy intake independent of portion size (55 +\/- 9 kcal; P &lt; 0.0001). By combining substitution with a reduction in energy density, meal energy intake decreased by 14 +\/- 3%. CONCLUSIONS: Serving more vegetables, either by adding more or substituting them for other foods, is an effective strategy to increase vegetable intake at a meal. However, to moderate meal energy intake, vegetables should be low in energy density; furthermore, the substitution of vegetables for more energy-dense foods is more effective than simply adding extra vegetables.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-42059","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutritional Sciences, The Pennsylvania State University, University Park, PA, USA. bjr4@psu.edu","annee":"2010","mois":"4","numero":"91:4","page":"913-22","auteurs":[{"ID":36867,"post_author":"0","post_date":"2018-12-04 01:07:54","post_date_gmt":"2018-12-04 00:07:54","post_content":"","post_title":"Liane S Roe","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"liane-s-roe","to_ping":"","pinged":"","post_modified":"2018-12-04 01:07:54","post_modified_gmt":"2018-12-04 00:07:54","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/liane-s-roe\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":36868,"post_author":"0","post_date":"2018-12-04 01:07:55","post_date_gmt":"2018-12-04 00:07:55","post_content":"","post_title":"Jennifer S Meengs","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jennifer-s-meengs","to_ping":"","pinged":"","post_modified":"2018-12-04 01:07:55","post_modified_gmt":"2018-12-04 00:07:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jennifer-s-meengs\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":16187,"post_author":"0","post_date":"2018-12-03 19:35:49","post_date_gmt":"2018-12-03 18:35:49","post_content":"","post_title":"Barbara J Rolls","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"barbara-j-rolls","to_ping":"","pinged":"","post_modified":"2018-12-03 19:35:49","post_modified_gmt":"2018-12-03 18:35:49","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/barbara-j-rolls\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1720,"post_author":"0","post_date":"2018-12-03 16:01:56","post_date_gmt":"2018-12-03 15:01:56","post_content":"","post_title":"Am J Clin Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-clin-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:56","post_modified_gmt":"2018-12-03 15:01:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-clin-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
