The optimal amount of vegetable consumption required to reduce chronic disease risk is widely debated. Intervention trials evaluating biological activity of vegetables at various doses are limited. We conducted a 3-dose, crossover feeding trial to test the hypothesis that vegetable intake is associated in a dose-dependent manner with increased plasma carotenoids and subsequently reduced oxidative stress and inflammation in 49 overweight, postmenopausal women. Participants were assigned in random order to 2 (130 g), 5 (287 g), and 10 (614 g) daily servings of fresh, greenhouse-grown vegetables for 3-wk intervals with a 4-wk washout period between treatments. Plasma total carotenoids significantly increased from 1.63 to 2.07 μmol\/L with a dose of 2 vegetable servings, from 1.49 to 2.84 μmol\/L with a dose of 5 vegetable servings, and from 1.40 to 4.42 μmol\/L with a dose of 10 vegetable servings (pre-post paired ttests, all P < 0.001). The change during each feeding period increased with each dose level (P < 0.001). Urine concentrations of 8-isoprostane F2α, hexanoyl lysine, and serum high sensitivity C-reactive protein were not affected by any administered vegetable dose. In this variable-dose vegetable study, a dose-response for plasma carotenoids was demonstrated without significant change in oxidative stress and inflammation in overweight, postmenopausal women.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-38165","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutritional Sciences, University of Arizona, Tucson, AZ, USA.\r\n","annee":"2011","mois":"10","numero":"141:10","page":"1827-1833","auteurs":[{"ID":19282,"post_author":"0","post_date":"2018-12-03 20:19:09","post_date_gmt":"2018-12-03 19:19:09","post_content":"","post_title":"Tracy E Crane","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"tracy-e-crane","to_ping":"","pinged":"","post_modified":"2018-12-03 20:19:09","post_modified_gmt":"2018-12-03 19:19:09","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/tracy-e-crane\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38163,"post_author":"0","post_date":"2018-12-04 01:32:22","post_date_gmt":"2018-12-04 00:32:22","post_content":"","post_title":"Kubota","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kubota","to_ping":"","pinged":"","post_modified":"2018-12-04 01:32:22","post_modified_gmt":"2018-12-04 00:32:22","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kubota\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":38164,"post_author":"0","post_date":"2018-12-04 01:32:23","post_date_gmt":"2018-12-04 00:32:23","post_content":"","post_title":"West","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"west-2","to_ping":"","pinged":"","post_modified":"2018-12-04 01:32:23","post_modified_gmt":"2018-12-04 00:32:23","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/west-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":32402,"post_author":"0","post_date":"2018-12-03 23:58:36","post_date_gmt":"2018-12-03 22:58:36","post_content":"","post_title":"J NUTR","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"j-nutr-2","to_ping":"","pinged":"","post_modified":"2018-12-03 23:58:36","post_modified_gmt":"2018-12-03 22:58:36","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/j-nutr-2\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nIncreasing the vegetable intake dose is associated with a rise in plasma carotenoids without modifying oxidative stress or inflammation in overweight or obese postmenopausal women. -
