ALV in the dish consisted mainly of Amaranthus cruentus (at least 80 %) and the remainder of Cleome gynandra, Cucurbita maxima or Vigna unguiculata. Nutrient content and consumer acceptance of the ALV dish were also determined.<\/p>\n<p><strong>SETTING:<\/strong><\/p>\n<p>North West Province, South Africa.<\/p>\n<p><strong>SUBJECTS:<\/strong><\/p>\n<p>Grade R to grade 4 children (6-12 years old) of two farm schools.<\/p>\n<p><strong>RESULTS:<\/strong><\/p>\n<p>The ALV dish contributed 11&middot;6-15&middot;8 mg Fe and 1&middot;4-3&middot;7 mg Zn. At baseline, prevalence of deficiencies in the intervention group was 16&middot;0 %, 16&middot;3 %, 7&middot;0 % and 75&middot;6 %, respectively, for anaemia (Hb&lt;11&middot;5 g\/dl), Fe (serum ferritin&lt;15 &micro;g\/l), vitamin A (serum retinol&lt;20 &mu;g\/dl) and Zn (serum Zn&lt;65 &mu;g\/dl); and in the control group 10&middot;5 %, 18&middot;5 %, 2&middot;5 % and 75&middot;3 %, respectively. No significant estimated intervention effect was found.<\/p>\n<p><strong>CONCLUSIONS:<\/strong><\/p>\n<p>This randomized controlled trial showed that ALV were unable to improve serum retinol, serum ferritin or Hb if there are only mild deficiencies present. Furthermore, despite the low Zn status in the study population, ALV consumption did not improve serum Zn concentrations either.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-25789","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Africa Unit for Transdisciplinary Health Research, Faculty of Health Sciences,North-West University,Potchefstroom,South Africa.","annee":"2015","mois":"7","numero":"","page":"","auteurs":[{"ID":25786,"post_author":"0","post_date":"2018-12-03 22:27:42","post_date_gmt":"2018-12-03 21:27:42","post_content":"","post_title":"Marinka Van Der Hoeven","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"marinka-van-der-hoeven","to_ping":"","pinged":"","post_modified":"2018-12-03 22:27:42","post_modified_gmt":"2018-12-03 21:27:42","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/marinka-van-der-hoeven\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":25787,"post_author":"0","post_date":"2018-12-03 22:27:43","post_date_gmt":"2018-12-03 21:27:43","post_content":"","post_title":"Jennifer Osei","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"jennifer-osei","to_ping":"","pinged":"","post_modified":"2018-12-03 22:27:43","post_modified_gmt":"2018-12-03 21:27:43","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/jennifer-osei\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":18274,"post_author":"0","post_date":"2018-12-03 20:02:47","post_date_gmt":"2018-12-03 19:02:47","post_content":"","post_title":"Annamarie Kruger","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"annamarie-kruger","to_ping":"","pinged":"","post_modified":"2018-12-03 20:02:47","post_modified_gmt":"2018-12-03 19:02:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/annamarie-kruger\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":14530,"post_author":"0","post_date":"2018-12-03 19:10:49","post_date_gmt":"2018-12-03 18:10:49","post_content":"","post_title":"Mieke Faber","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mieke-faber","to_ping":"","pinged":"","post_modified":"2018-12-03 19:10:49","post_modified_gmt":"2018-12-03 18:10:49","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mieke-faber\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":25788,"post_author":"0","post_date":"2018-12-03 22:27:44","post_date_gmt":"2018-12-03 21:27:44","post_content":"","post_title":"Cornelius M Smuts","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"cornelius-m-smuts","to_ping":"","pinged":"","post_modified":"2018-12-03 22:27:44","post_modified_gmt":"2018-12-03 21:27:44","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/cornelius-m-smuts\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1299,"post_author":"0","post_date":"2018-12-03 15:58:08","post_date_gmt":"2018-12-03 14:58:08","post_content":"","post_title":"Public health nutrition","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"public-health-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-03 15:58:08","post_modified_gmt":"2018-12-03 14:58:08","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/public-health-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) -
