A randomised controlled trial (ISRCTN50011192) with a cross-over design was conducted in free-living participants with early stages of hypertension (diastolic BP&gt;80 and &lt; 100 mmHg, not receiving BP-lowering medication) to test this hypothesis. Following a 3-week run-in period on a control diet, each subject completed four dietary 6-week dietary interventions (control+placebo capsules, an additional 20 or 40 mmol K(+)\/d from fruit and vegetables or 40 mmol potassium citrate capsules\/d) using a Latin square design with a washout period &#8805; 5 weeks between the treatment periods. Out of fifty-seven subjects who were randomised, twenty-three male and twenty-five female participants completed the study; compliance to the intervention was corroborated by food intake records and increased urinary K(+) excretion; plasma lipids, vitamin C, folate and homocysteine concentrations, urinary Na excretion, and body weight remained were unchanged. On the control diet, mean ambulatory 24 h systolic\/diastolic BP were 132\u00b73 (sd 12\u00b70)\/81\u00b79 ((SD) 7\u00b79) mmHg, and changes (Bonferroni&#039;s adjusted 95 % CI) compared with the control on the diets providing 20 and 40 mmol K(+)\/d as fruit and vegetables were 0\u00b78 (- 3\u00b75, 5\u00b73)\/0\u00b78 (- 1\u00b79, 3\u00b75) and 1\u00b77 (- 3\u00b70, 5\u00b73)\/1\u00b75 (- 1\u00b75, 4\u00b74), respectively, and were 1\u00b78 (- 2\u00b71, 5\u00b78)\/1\u00b74 (- 1\u00b76, 4\u00b74) mmHg on the 40 mmol potassium citrate supplement, and were not statistically significant. Arterial stiffness, endothelial function, and urinary and plasma isoprostane and C-reactive protein (CRP) concentrations did not differ significantly between the diets. The present study provides no evidence to support dietary advice to increase K intake above usual UK intakes in the subjects with early stages of hypertension.<\/p>\n","protected":false},"template":"","mots_cles":[4189],"class_list":["post-39638","resume","type-resume","status-publish","hentry","mots_cles-potassium"],"acf":{"adresse":"King's College London, UK.\r\n","annee":"2010","mois":"12","numero":"104:12","page":"1839-47","auteurs":[{"ID":39635,"post_author":"0","post_date":"2018-12-04 02:00:57","post_date_gmt":"2018-12-04 01:00:57","post_content":"","post_title":"Berry","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"berry","to_ping":"","pinged":"","post_modified":"2018-12-04 02:00:57","post_modified_gmt":"2018-12-04 01:00:57","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/berry\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39636,"post_author":"0","post_date":"2018-12-04 02:00:58","post_date_gmt":"2018-12-04 01:00:58","post_content":"","post_title":"Mulla","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mulla","to_ping":"","pinged":"","post_modified":"2018-12-04 02:00:58","post_modified_gmt":"2018-12-04 01:00:58","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mulla\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39637,"post_author":"0","post_date":"2018-12-04 02:00:59","post_date_gmt":"2018-12-04 01:00:59","post_content":"","post_title":"Chowienczyk","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"chowienczyk","to_ping":"","pinged":"","post_modified":"2018-12-04 02:00:59","post_modified_gmt":"2018-12-04 01:00:59","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/chowienczyk\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":33299,"post_author":"0","post_date":"2018-12-04 00:11:13","post_date_gmt":"2018-12-03 23:11:13","post_content":"","post_title":"Thomas Ab Sanders","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"thomas-ab-sanders","to_ping":"","pinged":"","post_modified":"2018-12-04 00:11:13","post_modified_gmt":"2018-12-03 23:11:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/thomas-ab-sanders\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1559,"post_author":"0","post_date":"2018-12-03 16:00:30","post_date_gmt":"2018-12-03 15:00:30","post_content":"","post_title":"Br J Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"br-j-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:30","post_modified_gmt":"2018-12-03 15:00:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/br-j-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) -
