\u00ab\u00a0OBJECTIVE: We investigated the effect of long-term antioxidant supplementation (lutein and a-tocopherol) on serum levels and visual performance in patients with cataracts.METHODS: Seventeen patients clinically diagnosed with age-related cataracts were randomized in; a double-blind study involving dietary supplementation with lutein (15 mg; n = 5), a-tocopherol (100 mg; n = 6), or placebo (n = 6), three times a week for up to 2 y. Serum carotenoid and tocopherol concentrations were determined with quality-controlled high-performance liquid chromatography, and visual performance (visual activity and glare sensitivity) and biochemical and hematologic, indexes monitored every 3 mo throughout the study. Changes in these parameters were assessed by General Linear Model (GLM) repeated measures analysis.RESULTS: Serum concentrations of lutein and alpha-tocopherol increased with supplementation, although statistical significance was reached only in the lutein group. Visual performance (visual acuity. and glare sensitivity) improved in the lutein group, whereas there was a trend toward the maintenance of and decrease in visual acuity with alpha-tocopherol and placebo supplementation, respectively. No significant side., effects or-changes,in,biochemical or hematologic profiles were-observed in any of:the subjects during the, study.CONCLUSIONS: Visual function in patients with age-related cataracts who received the lutein supplements improved, suggesting, that a higher intake of lutein, through lutein-rich fruit and vegetables or supplements, may have beneficial effects! on the visual performance of people with age-related cataracts.\u00a0\u00bb<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-54846","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"OLMEDILLA B,CLIN PUERTA & HIERRO,SECC NUTR UNIDAD VITAMINAS;SAN MARTIN PORRES 4; MADRID 28035, SPAIN. bolmedilla@hpth.insalud.es \"","annee":"2003","mois":"1","numero":"19:1","page":"21-24","auteurs":[{"ID":46438,"post_author":"0","post_date":"2018-12-04 03:58:29","post_date_gmt":"2018-12-04 02:58:29","post_content":"","post_title":"Granado-lorencio","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"granado-lorencio","to_ping":"","pinged":"","post_modified":"2018-12-04 03:58:29","post_modified_gmt":"2018-12-04 02:58:29","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/granado-lorencio\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":21681,"post_author":"0","post_date":"2018-12-03 20:53:04","post_date_gmt":"2018-12-03 19:53:04","post_content":"","post_title":"Bego\u00f1a Olmedilla-Alonso","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"begona-olmedilla-alonso-2","to_ping":"","pinged":"","post_modified":"2018-12-03 20:53:04","post_modified_gmt":"2018-12-03 19:53:04","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/begona-olmedilla-alonso-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46439,"post_author":"0","post_date":"2018-12-04 03:58:31","post_date_gmt":"2018-12-04 02:58:31","post_content":"","post_title":"Blanco-navarro","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"blanco-navarro","to_ping":"","pinged":"","post_modified":"2018-12-04 03:58:31","post_modified_gmt":"2018-12-04 02:58:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/blanco-navarro\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":52699,"post_author":"0","post_date":"2018-12-04 06:07:24","post_date_gmt":"2018-12-04 05:07:24","post_content":"","post_title":"Vaquero","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"vaquero-2","to_ping":"","pinged":"","post_modified":"2018-12-04 06:07:24","post_modified_gmt":"2018-12-04 05:07:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/vaquero-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":15994,"post_author":"0","post_date":"2018-12-03 19:33:24","post_date_gmt":"2018-12-03 18:33:24","post_content":"","post_title":"NUTRITION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"nutrition","to_ping":"","pinged":"","post_modified":"2018-12-03 19:33:24","post_modified_gmt":"2018-12-03 18:33:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/nutrition\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nLutein, but not alpha-tocopherol, supplementation improves visual function in patients with age-related cataracts: a 2-y double-blind, placebo-controlled pilot study -
