OBJECTIVES: <\/strong>
\nThe Dietary Guidelines for Americans 2005 recommended that consumers give priority to nutrient-dense foods, those that contain substantial amounts of key nutrients in relation to the dietary energy they provide. This study developed a scoring system to estimate the nutritional adequacy of vegetables and fruits, on a per weight, per calorie, and per unit cost basis.<\/p>\n

DATA:<\/strong>
\nWe used a French national food composition database for 637 foods, including 129 vegetables and fruits. Mean national retail prices were obtained for each food.<\/p>\n

METHODS: <\/strong>
\nThe nutrient adequacy score was defined as the mean of percent daily values for 16 nutrients, based on 100 g of food. The nutrient density score and the nutrient-to-price ratio were the mean of percent daily values for 16 nutrients, expressed per 100 kcal and per 1 euro of food, respectively. Relationships between energy density of vegetables and fruits, nutrient adequacy score, nutrient density score, and nutrient-to-price ratio were tested using linear regression.<\/p>\n

RESULTS: <\/strong>
\nEnergy density and nutrient density score were negatively correlated, confirming the widely accepted notion that energy-dense foods tend to be nutrient-poor. As expected, fruits and vegetables had the highest nutrient density score because they were nutrient-rich in relation to their low energy content. They also had a relatively high nutrient-to-price ratio, showing that they provided nutrients at a reasonable cost when compared with other foods.<\/p>\n

CONCLUSIONS:<\/strong>
\nFoods ranked differently when nutritional adequacy was calculated per weight (nutrient adequacy score), per calorie (nutrient density score), or per unit cost (nutrient-to-price ratio). The present results showed that although fruits and vegetables are an expensive source of dietary energy, they provide key nutrients at a reasonable cost.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-49640","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Institut Scientifique et Technique de la Nutrition et de l'Alimentation, Paris, France.","annee":"2005","mois":"12","numero":"105:12","page":"1881-1887","auteurs":[{"ID":7678,"post_author":"0","post_date":"2018-12-03 17:51:47","post_date_gmt":"2018-12-03 16:51:47","post_content":"","post_title":"Nicole Darmon","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"nicole-darmon","to_ping":"","pinged":"","post_modified":"2018-12-03 17:51:47","post_modified_gmt":"2018-12-03 16:51:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/nicole-darmon\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":9736,"post_author":"0","post_date":"2018-12-03 18:14:34","post_date_gmt":"2018-12-03 17:14:34","post_content":"","post_title":"Adam Drewnowski","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"adam-drewnowski","to_ping":"","pinged":"","post_modified":"2018-12-03 18:14:34","post_modified_gmt":"2018-12-03 17:14:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/adam-drewnowski\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46491,"post_author":"0","post_date":"2018-12-04 03:59:55","post_date_gmt":"2018-12-04 02:59:55","post_content":"","post_title":"Darmon","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"darmon","to_ping":"","pinged":"","post_modified":"2018-12-04 03:59:55","post_modified_gmt":"2018-12-04 02:59:55","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/darmon\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":8532,"post_author":"0","post_date":"2018-12-03 18:01:13","post_date_gmt":"2018-12-03 17:01:13","post_content":"","post_title":"Matthieu Maillot","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"matthieu-maillot","to_ping":"","pinged":"","post_modified":"2018-12-03 18:01:13","post_modified_gmt":"2018-12-03 17:01:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/matthieu-maillot\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":45166,"post_author":"0","post_date":"2018-12-04 03:37:42","post_date_gmt":"2018-12-04 02:37:42","post_content":"","post_title":"JOURNAL OF AMERICAN DIETETIC ASSOCIATION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-american-dietetic-association","to_ping":"","pinged":"","post_modified":"2018-12-04 03:37:42","post_modified_gmt":"2018-12-04 02:37:42","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-american-dietetic-association\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nA nutrient density standard for vegetables and fruits: nutrients per calorie and nutrients per unit cost. -
