Pur\u00e9ed F&amp;V products retain many beneficial components, including flavonoids, carotenoids, vitamin C and dietary fibres. The present study aimed to establish the physiological effects of acute ingestion of a F&amp;V pur\u00e9e-based drink (FVPD) on vasodilation, antioxidant status, phytochemical bioavailability and other CVD risk factors. A total of twenty-four subjects, aged 30-70 years, completed the randomised, single-blind, controlled, crossover test meal study. Subjects consumed 400 ml of the FVPD, or a fruit-flavoured sugar-matched control, after following a low-flavonoid diet for 5 d. Blood and urine samples were collected throughout the study day, and vascular reactivity was assessed at 90 min intervals using laser Doppler iontophoresis. The FVPD significantly increased plasma vitamin C (P = 0\u00b7002) and total nitrate\/nitrite (P = 0\u00b7001) concentrations. There was a near significant time by treatment effect on ex vivo LDL oxidation (P = 0\u00b7068), with a longer lag phase after consuming the FVPD. During the 6 h after juice consumption, the antioxidant capacity of plasma increased significantly (P = 0\u00b7003) and there was a simultaneous increase in plasma and urinary phenolic metabolites (P &lt; 0\u00b705). There were significantly lower glucose and insulin peaks after ingestion of the FVPD compared with control (P = 0\u00b7019 and 0\u00b7003) and a trend towards increased endothelium-dependent vasodilation following FVPD consumption (P = 0\u00b7061). Overall, FVPD consumption significantly increased plasma vitamin C and total nitrate\/nitrite concentrations, with a trend towards increased endothelium-dependent vasodilation. Pur\u00e9ed F&amp;V products are useful vehicles for increasing micronutrient status, plasma antioxidant capacity and in vivo NO generation, which may contribute to CVD risk reduction.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-35564","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Hugh Sinclair Unit of Human Nutrition, Department of Food and Nutritional Sciences, School of Chemistry, Food and Pharmacy, University of Reading, Whiteknights, PO Box 226, Reading, Berks RG6 6AP, UK.","annee":"2012","mois":"9","numero":"28","page":"1-11","auteurs":[{"ID":30625,"post_author":"0","post_date":"2018-12-03 23:34:20","post_date_gmt":"2018-12-03 22:34:20","post_content":"","post_title":"Trevor W George","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"trevor-w-george","to_ping":"","pinged":"","post_modified":"2018-12-03 23:34:20","post_modified_gmt":"2018-12-03 22:34:20","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/trevor-w-george\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35562,"post_author":"0","post_date":"2018-12-04 00:46:02","post_date_gmt":"2018-12-03 23:46:02","post_content":"","post_title":"Niwat","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"niwat","to_ping":"","pinged":"","post_modified":"2018-12-04 00:46:02","post_modified_gmt":"2018-12-03 23:46:02","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/niwat\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35563,"post_author":"0","post_date":"2018-12-04 00:46:03","post_date_gmt":"2018-12-03 23:46:03","post_content":"","post_title":"Waroonphan","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"waroonphan","to_ping":"","pinged":"","post_modified":"2018-12-04 00:46:03","post_modified_gmt":"2018-12-03 23:46:03","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/waroonphan\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1559,"post_author":"0","post_date":"2018-12-03 16:00:30","post_date_gmt":"2018-12-03 15:00:30","post_content":"","post_title":"Br J Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"br-j-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:30","post_modified_gmt":"2018-12-03 15:00:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/br-j-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) -
