Our main sources of fructose are sucrose from beet or cane, high fructose corn syrup, fruits, and honey. Fructose has the same chemical formula as glucose (C(6)H(12)O(6)), but its metabolism differs markedly from that of glucose due to its almost complete hepatic extraction and rapid hepatic conversion into glucose, glycogen, lactate, and fat. Fructose was initially thought to be advisable for patients with diabetes due to its low glycemic index. However, chronically high consumption of fructose in rodents leads to hepatic and extrahepatic insulin resistance, obesity, type 2 diabetes mellitus, and high blood pressure. The evidence is less compelling in humans, but high fructose intake has indeed been shown to cause dyslipidemia and to impair hepatic insulin sensitivity. Hepatic de novo lipogenesis and lipotoxicity, oxidative stress, and hyperuricemia have all been proposed as mechanisms responsible for these adverse metabolic effects of fructose. Although there is compelling evidence that very high fructose intake can have deleterious metabolic effects in humans as in rodents, the role of fructose in the development of the current epidemic of metabolic disorders remains controversial. Epidemiological studies show growing evidence that consumption of sweetened beverages (containing either sucrose or a mixture of glucose and fructose) is associated with a high energy intake, increased body weight, and the occurrence of metabolic and cardiovascular disorders. There is, however, no unequivocal evidence that fructose intake at moderate doses is directly related with adverse metabolic effects. There has also been much concern that consumption of free fructose, as provided in high fructose corn syrup, may cause more adverse effects than consumption of fructose consumed with sucrose. There is, however, no direct evidence for more serious metabolic consequences of high fructose corn syrup versus sucrose consumption.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-41451","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Physiology, Faculty of Biology and Medicine, University of Lausanne, CH-1005 Lausanne, Switzerland. luc.tappy@unil.ch","annee":"2010","mois":"1","numero":"90:1","page":"23-46","auteurs":[{"ID":41449,"post_author":"0","post_date":"2018-12-04 02:32:49","post_date_gmt":"2018-12-04 01:32:49","post_content":"","post_title":"Tappy","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"tappy","to_ping":"","pinged":"","post_modified":"2018-12-04 02:32:49","post_modified_gmt":"2018-12-04 01:32:49","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/tappy\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":32988,"post_author":"0","post_date":"2018-12-04 00:07:09","post_date_gmt":"2018-12-03 23:07:09","post_content":"","post_title":"Kate A Levin","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kate-a-levin","to_ping":"","pinged":"","post_modified":"2018-12-04 00:07:09","post_modified_gmt":"2018-12-03 23:07:09","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kate-a-levin\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":41450,"post_author":"0","post_date":"2018-12-04 02:32:50","post_date_gmt":"2018-12-04 01:32:50","post_content":"","post_title":"PHYSIOL REV","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"physiol-rev","to_ping":"","pinged":"","post_modified":"2018-12-04 02:32:50","post_modified_gmt":"2018-12-04 01:32:50","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/physiol-rev\/","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) -
