The present study was performed to evaluate the antioxidative effects of a plant oil mixture rich in alpha-tocopherol (olive\/sunflower oil) in comparison with a single gamma-tocopherol-rich corn oil used in a normal, balanced human diet.<\/p>\n<p style=\"text-align: justify\"><strong>METHODS:<\/strong><br \/>\nIn the context of a double-blind study 28 healthy nonsmoking male volunteers aged between 19 and 31 years were investigated. After 2 weeks of adjustment on a mixed, balanced diet (average 11.6 MJ, average fat intake approximately 105 g\/day), a 2-week test period with a diet of 80 g corn oil (CO)\/day vs. a mixture of 68 g olive and 12 g sunflower oil\/day (MO; total 80 g) as the main fat source, was followed by a crossover after 2 weeks. Blood samples were collected at the beginning of the study and at 2-week intervals.<\/p>\n<p style=\"text-align: justify\"><strong>RESULTS: <\/strong><br \/>\nThe main carriers of tocopherol in blood are low-density lipoproteins (LDLs). A highly significant correlation (r2 = 0.73, p &lt; 0.001) was found between plasma and LDL gamma-tocopherol concentrations in the CO group, and a significant correlation was found between plasma and LDL alpha-tocopherol concentrations only in the MO group. Plasma and LDL total antioxidative capacity values could only be improved insignificantly in both groups to comparable extents, although the MO group had a twofold higher alpha-tocopherol equivalent\/diene equivalent ratio (1.13 mg\/g) than the CO group (0.55 mg\/g).<\/p>\n<p style=\"text-align: justify\"><strong>CONCLUSION:<\/strong><br \/>\nIn spite of the higher P\/S ratio (CO 4.2 vs. MO 1.2) and lower alpha-tocopherol equivalent\/diene equivalent ratio, the antioxidant potential of CO in vivo (total antioxidative capacity in plasma and LDL) was as efficient as the MO. This positive finding might be explained by a synergism between alpha- and gamma-tocopherol in the CO diet.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56553","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Institute of Nutritional Sciences, University of Vienna, Austria.","annee":"2001","mois":"3","numero":"45:3","page":"110-115","auteurs":[{"ID":25079,"post_author":"0","post_date":"2018-12-03 22:11:15","post_date_gmt":"2018-12-03 21:11:15","post_content":"","post_title":"Ibrahim Elmadfa","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ibrahim-elmadfa","to_ping":"","pinged":"","post_modified":"2018-12-03 22:11:15","post_modified_gmt":"2018-12-03 21:11:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ibrahim-elmadfa\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56551,"post_author":"0","post_date":"2018-12-04 07:24:19","post_date_gmt":"2018-12-04 06:24:19","post_content":"","post_title":"Tomasch","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"tomasch","to_ping":"","pinged":"","post_modified":"2018-12-04 07:24:19","post_modified_gmt":"2018-12-04 06:24:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/tomasch\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39740,"post_author":"0","post_date":"2018-12-04 02:02:35","post_date_gmt":"2018-12-04 01:02:35","post_content":"","post_title":"Wagner","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"wagner","to_ping":"","pinged":"","post_modified":"2018-12-04 02:02:35","post_modified_gmt":"2018-12-04 01:02:35","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/wagner\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":56552,"post_author":"0","post_date":"2018-12-04 07:24:20","post_date_gmt":"2018-12-04 06:24:20","post_content":"","post_title":"Annals of nutrition &amp; metabolism","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"annals-of-nutrition-metabolism-27","to_ping":"","pinged":"","post_modified":"2018-12-04 07:24:20","post_modified_gmt":"2018-12-04 06:24:20","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/annals-of-nutrition-metabolism-27\/","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) -
