The subjects were then randomly assigned to 1 of 3 groups to consume 2 servings\/d, 5 servings\/d, or 8 servings\/d of carotenoid-rich vegetables and fruit for another 4-wk period. Plasma concentrations of vitamins C and E and carotenoids were measured. The assessment of immunologic and inflammatory markers included the number and activity of natural killer cells, secretion of cytokines, lymphocyte proliferation, and plasma C-reactive protein concentrations.<\/p>\n<p><strong>RESULTS:<\/strong><br \/>\nThe high intake (8 servings\/d) of vegetables and fruit significantly increased total carotenoid concentrations in plasma compared with the low intake (2 servings\/d; week 4 compared with week 8), whereas concentrations of vitamins C and E did not differ between week 4 and week 8. Immunologic markers were not significantly modulated. In contrast, C-reactive protein was significantly reduced at week 8 in the subjects who consumed 8 servings\/d of vegetables and fruit compared with those who consumed 2 servings\/d.<\/p>\n<p><strong>CONCLUSIONS:<\/strong><br \/>\nIn healthy, well-nourished, nonsmoking men, 4 wk of low or high intakes of carotenoid-rich vegetables and fruit did not affect markers of immune function. However, a high intake of vegetables and fruit may reduce inflammatory processes, as indicated by the reduction of plasma C-reactive protein.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-49809","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"","annee":"2005","mois":"11","numero":"82:5","page":"1052-1058","auteurs":[{"ID":6380,"post_author":"0","post_date":"2018-12-03 17:37:46","post_date_gmt":"2018-12-03 16:37:46","post_content":"","post_title":"Bernhard Watzl","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bernhard-watzl","to_ping":"","pinged":"","post_modified":"2018-12-03 17:37:46","post_modified_gmt":"2018-12-03 16:37:46","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bernhard-watzl\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1720,"post_author":"0","post_date":"2018-12-03 16:01:56","post_date_gmt":"2018-12-03 15:01:56","post_content":"","post_title":"Am J Clin Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"am-j-clin-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:56","post_modified_gmt":"2018-12-03 15:01:56","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/am-j-clin-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) -
