In fresh vegetables, these properties include vitamins, minerals, dietary fiber, and secondary compounds, which collectively impart a large portion of the dietary, nutritional or health value associated with vegetable intake. Many, including farmers, aim to increase the health-promoting properties of fresh vegetables on the whole but they face at least three obstacles. First, describing crop composition in terms of its nutrition-based impact on human health is complex and there are few, if any, accepted processes and associated metrics for assessing and managing vegetable composition on-farm, at the origin of supply. Second, data suggest that primary and secondary metabolism can be &#039;in conflict&#039; when establishing the abundance versus composition of a crop. Third, fresh vegetable farmers are rarely compensated for the phytochemical composition of their product. The development and implementation of a fresh vegetable &#039;nutritional yield&#039; index could be instrumental in overcoming these obstacles. Nutritional yield is a function of crop biomass and tissue levels of health-related metabolites, including bioavailable antioxidant potential. Data from a multi-factor study of leaf lettuce primary and secondary metabolism and the literature suggest that antioxidant yield is sensitive to genetic and environmental production factors, and that changes in crop production and valuation will be required for fresh vegetable production systems to become more focused and purposeful instruments of public health.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-35716","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Horticulture and Crop Science, The Ohio State University\/OARDC, Wooster, OH 44691, USA.","annee":"2012","mois":"9","numero":"67:3","page":"215-222","auteurs":[{"ID":35713,"post_author":"0","post_date":"2018-12-04 00:48:14","post_date_gmt":"2018-12-03 23:48:14","post_content":"","post_title":"Bumgarner","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bumgarner","to_ping":"","pinged":"","post_modified":"2018-12-04 00:48:14","post_modified_gmt":"2018-12-03 23:48:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bumgarner\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35714,"post_author":"0","post_date":"2018-12-04 00:48:15","post_date_gmt":"2018-12-03 23:48:15","post_content":"","post_title":"Scheerens","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"scheerens","to_ping":"","pinged":"","post_modified":"2018-12-04 00:48:15","post_modified_gmt":"2018-12-03 23:48:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/scheerens\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":35715,"post_author":"0","post_date":"2018-12-04 00:48:16","post_date_gmt":"2018-12-03 23:48:16","post_content":"","post_title":"Kleinhenz","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kleinhenz","to_ping":"","pinged":"","post_modified":"2018-12-04 00:48:16","post_modified_gmt":"2018-12-03 23:48:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kleinhenz\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":28371,"post_author":"0","post_date":"2018-12-03 23:06:05","post_date_gmt":"2018-12-03 22:06:05","post_content":"","post_title":"Plant Foods Hum Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"plant-foods-hum-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 23:06:05","post_modified_gmt":"2018-12-03 22:06:05","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/plant-foods-hum-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) -
