OBJECTIVES: Higher plasma micronutrient levels have been associated with decreased cancer risks. The objective of this study was to determine the relative effects of reduced fat and\/or increased fruit-vegetable (FV) intakes on plasma micronutrient levels. METHODS: Healthy, premenopausal women with a family history of breast cancer (n = 122) were randomized across four diet arms for one year in a 2 x 2 factorial design study: control, low-fat, high fruit-vegetable and combination low-fat\/high FV diets. Levels of plasma micronutrients were measured in plasma at 0, 3, 6 and 12 months. RESULTS: The high FV intervention, regardless of fat intake, significantly increased alpha-carotene, beta-carotene and vitamin C levels in plasma. Only the combination high FV, low-fat intervention significantly increased plasma beta-cryptoxanthin and zeaxanthin levels over time. Although alpha-tocopherol was not affected, a potential concern is that the low-fat intervention resulted in significantly decreased both gamma-tocopherol dietary intakes and plasma levels, regardless of whether or not FV intakes were concomitantly increased. CONCLUSIONS: Unlike alpha-tocopherol, gamma-tocopherol plasma levels were decreased by a low fat diet, perhaps because gamma-tocopherol is not generally added to foods nor widely used in vitamin E supplements. The decreased dietary intakes and plasma levels of gamma-tocopherol with a low-fat diet may have implications for health risks since the biological functions of the different tocopherol isomers have been reported to be distinct.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-48664","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Deapartment of Family Medicine, University of Michigan, Ann Arbor, MI 48109-0930, USA. zoralong@umich.edu","annee":"2006","mois":"6","numero":"25:3","page":"178-87","auteurs":[{"ID":46729,"post_author":"0","post_date":"2018-12-04 04:06:16","post_date_gmt":"2018-12-04 03:06:16","post_content":"","post_title":"Heilbrun","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"heilbrun","to_ping":"","pinged":"","post_modified":"2018-12-04 04:06:16","post_modified_gmt":"2018-12-04 03:06:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/heilbrun\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":48427,"post_author":"0","post_date":"2018-12-04 04:33:42","post_date_gmt":"2018-12-04 03:33:42","post_content":"","post_title":"Van Bladeren","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"van-bladeren","to_ping":"","pinged":"","post_modified":"2018-12-04 04:33:42","post_modified_gmt":"2018-12-04 03:33:42","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/van-bladeren\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":48663,"post_author":"0","post_date":"2018-12-04 04:40:32","post_date_gmt":"2018-12-04 03:40:32","post_content":"","post_title":"Mekhovich","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mekhovich","to_ping":"","pinged":"","post_modified":"2018-12-04 04:40:32","post_modified_gmt":"2018-12-04 03:40:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mekhovich\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":46731,"post_author":"0","post_date":"2018-12-04 04:06:19","post_date_gmt":"2018-12-04 03:06:19","post_content":"","post_title":"Venkatranamoorthy","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"venkatranamoorthy","to_ping":"","pinged":"","post_modified":"2018-12-04 04:06:19","post_modified_gmt":"2018-12-04 03:06:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/venkatranamoorthy\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":2123,"post_author":"0","post_date":"2018-12-03 16:52:35","post_date_gmt":"2018-12-03 15:52:35","post_content":"","post_title":"JOURNAL OF THE AMERICAN COLLEGE OF NUTRITION","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-the-american-college-of-nutrition","to_ping":"","pinged":"","post_modified":"2018-12-03 16:52:35","post_modified_gmt":"2018-12-03 15:52:35","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-the-american-college-of-nutrition\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nEffects of high fruit-vegetable and\/or low-fat intervention on plasma micronutrient levels. -
