The aim of the present study was to determine the effect of supplementation with dehydrated juice concentrates from mixed fruit and vegetables on selected plasma vitamins and antioxidant status. We assessed CHD risk by measuring the concentrations of homocysteine, lipids, lipoproteins, glucose and insulin. Men were recruited to participate in a randomized double-blind, crossover trial with 2 periods of 6 wk, separated by a 3-wk wash-out period. Supplementation with the encapsulated mixed extract (Juice Plus) was compared with physically similar placebo capsules. Thirty-two men (13 smokers, 19 nonsmokers) completed the study with a mean compliance of 88%. Compared with placebo, supplementation increased the concentrations of plasma beta-carotene (0.24 +\/- 0.15 vs. 1.12 +\/- 0.70 micro mol\/L; mean +\/- SD; P &lt; 0.0001), retinol (1.87 +\/- 0.33 vs. 2.00 +\/- 0.43 micro mol\/L; P &lt; 0.05), alpha-tocopherol (16.8 +\/- 7.3 vs. 19.3 +\/- 6.8 micro mol\/L; P &lt; 0.01), ascorbic acid (72.1 +\/- 19.4 vs. 84.1 +\/- 13.5 micro mol\/L; P &lt; 0.002) and folic acid (24.5 +\/- 10.0 vs. 44.9 +\/- 16.9 nmol\/L; P &lt; 0.0001). Plasma homocysteine was reduced (8.2 +\/- 1.5 vs. 7.6 +\/- 1.1; P &lt; 0.05) and inversely related (r = -0.40, P &lt; 0.001) with serum folate concentrations. Plasma vitamin C was positively correlated with the resistance of LDL to oxidation (r = 0.26, P &lt; 0.05) and the plasma ferric reducing\/antioxidant power (FRAP) tended to be greater after supplementation than after the placebo period (1125.5 +\/- 144.1 vs. 1180.3 +\/- 158.1 micro mol\/L; P &lt; 0.065). Plasma glucose, insulin and lipid concentrations were unaffected. Responses of smokers and nonsmokers did not differ. In the absence of dietary modification, supplementation with a fruit and vegetable concentrate produced responses consistent with a reduction in CHD risk.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54107","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Human Nutrition Unit, School of Molecular and Microbial Biosciences, University of Sydney, NSW, Australia. s.samman@mmb.usyd.edu.au","annee":"2003","mois":"7","numero":"133:7","page":"2188-2193","auteurs":[{"ID":54103,"post_author":"0","post_date":"2018-12-04 06:31:55","post_date_gmt":"2018-12-04 05:31:55","post_content":"","post_title":"Samman","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"samman","to_ping":"","pinged":"","post_modified":"2018-12-04 06:31:55","post_modified_gmt":"2018-12-04 05:31:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/samman\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54104,"post_author":"0","post_date":"2018-12-04 06:31:56","post_date_gmt":"2018-12-04 05:31:56","post_content":"","post_title":"Ahmad","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ahmad","to_ping":"","pinged":"","post_modified":"2018-12-04 06:31:56","post_modified_gmt":"2018-12-04 05:31:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ahmad\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54105,"post_author":"0","post_date":"2018-12-04 06:31:58","post_date_gmt":"2018-12-04 05:31:58","post_content":"","post_title":"Caterson","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"caterson","to_ping":"","pinged":"","post_modified":"2018-12-04 06:31:58","post_modified_gmt":"2018-12-04 05:31:58","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/caterson\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":34496,"post_author":"0","post_date":"2018-12-04 00:30:40","post_date_gmt":"2018-12-03 23:30:40","post_content":"","post_title":"Manderscheid","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"manderscheid","to_ping":"","pinged":"","post_modified":"2018-12-04 00:30:40","post_modified_gmt":"2018-12-03 23:30:40","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/manderscheid\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":2817,"post_author":"0","post_date":"2018-12-03 16:59:25","post_date_gmt":"2018-12-03 15:59:25","post_content":"","post_title":"Peter Petocz","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"peter-petocz","to_ping":"","pinged":"","post_modified":"2018-12-03 16:59:25","post_modified_gmt":"2018-12-03 15:59:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/peter-petocz\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":54106,"post_author":"0","post_date":"2018-12-04 06:32:01","post_date_gmt":"2018-12-04 05:32:01","post_content":"","post_title":"Sivarajah","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sivarajah","to_ping":"","pinged":"","post_modified":"2018-12-04 06:32:01","post_modified_gmt":"2018-12-04 05:32:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sivarajah\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":44294,"post_author":"0","post_date":"2018-12-04 03:21:12","post_date_gmt":"2018-12-04 02:21:12","post_content":"","post_title":"JOURNAL OF NUTRITION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-04 03:21:12","post_modified_gmt":"2018-12-04 02:21:12","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-nutrition\/","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) -
