However, few data from controlled human studies exist. The aim of the present study was to compare the carotenoid content and antioxidant capacity of organically and conventionally produced carrots under defined conditions. Furthermore, a human intervention study was conducted to compare bioavailability, plasma antioxidant capacity, endogenous DNA strand breaks and immune parameters in healthy men ingesting carrots from different agricultural systems. Thirty-six volunteers consumed either organically or conventionally produced blanched carrots (200 g\/d; 2 weeks) or no carrots in a double-blind, randomised intervention study. No statistically significant differences were observed in the total carotenoid contents (121 (sd 7) microg\/g organic v. 116 (sd 13) microg\/g conventional) and the antioxidant capacities (0.43 (sd 0.08) mumol Trolox equivalents\/g organic v. 0.32 (sd 0.07) mumol Trolox equivalents\/g conventional) of the carrots administered to the volunteers. Intake of organically or conventionally produced carrots significantly increased (P &lt; 0.001) plasma alpha- and beta-carotene concentrations in both intervention groups without differences in plasma carotenoid concentrations. Consumption of carrots did not lead to significant changes in the plasma antioxidant status, endogenous DNA strand breaks and parameters of the immune system in all groups. Therefore, these results indicate that the agricultural system has neither an effect on the carotenoid content, the antioxidant capacity of carrots, nor on the bioavailability of carotenoids and on antioxidant, antigenotoxic and immunological effects as assessed in a human intervention study.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-43173","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Institute of Physiology and Biochemistry of Nutrition, Max Rubner-Institut, Federal Research Institute of Nutrition and Food, Haid- und Neu-strasse 9, 76131 Karlsruhe, Germany.","annee":"2009","mois":"6","numero":"101:11","page":"1664-72","auteurs":[{"ID":2932,"post_author":"0","post_date":"2018-12-03 17:00:35","post_date_gmt":"2018-12-03 16:00:35","post_content":"","post_title":"Abdulai Abubakari","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"abdulai-abubakari","to_ping":"","pinged":"","post_modified":"2018-12-03 17:00:35","post_modified_gmt":"2018-12-03 16:00:35","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/abdulai-abubakari\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":41253,"post_author":"0","post_date":"2018-12-04 02:29:33","post_date_gmt":"2018-12-04 01:29:33","post_content":"","post_title":"Stracke","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"stracke","to_ping":"","pinged":"","post_modified":"2018-12-04 02:29:33","post_modified_gmt":"2018-12-04 01:29:33","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/stracke\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":41254,"post_author":"0","post_date":"2018-12-04 02:29:33","post_date_gmt":"2018-12-04 01:29:33","post_content":"","post_title":"Rufer","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"rufer","to_ping":"","pinged":"","post_modified":"2018-12-04 02:29:33","post_modified_gmt":"2018-12-04 01:29:33","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/rufer\/","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) -
