The human genome has hardly changed since the emergence of behaviourally-modern humans in East Africa 100-50 x 10(3) years ago; genetically, man remains adapted for the foods consumed then. The best available estimates suggest that those ancestors obtained about 35% of their dietary energy from fats, 35% from carbohydrates and 30% from protein. Saturated fats contributed approximately 7.5% total energy and harmful trans-fatty acids contributed negligible amounts. Polyunsaturated fat intake was high, with n-6:n-3 approaching 2:1 (v. 10:1 today). Cholesterol consumption was substantial, perhaps 480 mg\/d. Carbohydrate came from uncultivated fruits and vegetables, approximately 50% energy intake as compared with the present level of 16% energy intake for Americans. High fruit and vegetable intake and minimal grain and dairy consumption made ancestral diets base-yielding, unlike today&rsquo;s acid-producing pattern. Honey comprised 2-3% energy intake as compared with the 15% added sugars contribute currently. Fibre consumption was high, perhaps 100 g\/d, but phytate content was minimal. Vitamin, mineral and (probably) phytochemical intake was typically 1.5 to eight times that of today except for that of Na, generally &lt;1000 mg\/d, i.e. much less than that of K. The field of nutrition science suffers from the absence of a unifying hypothesis on which to build a dietary strategy for prevention; there is no Kuhnian paradigm, which some researchers believe to be a prerequisite for progress in any scientific discipline. An understanding of human evolutionary experience and its relevance to contemporary nutritional requirements may address this critical deficiency.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-49167","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Anthropology and Radiology, Emory University, Atlanta, GA 30327, USA.","annee":"2006","mois":"2","numero":"65:1","page":"1-6","auteurs":[{"ID":49166,"post_author":"0","post_date":"2018-12-04 04:52:07","post_date_gmt":"2018-12-04 03:52:07","post_content":"","post_title":"Eaton","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"eaton","to_ping":"","pinged":"","post_modified":"2018-12-04 04:52:07","post_modified_gmt":"2018-12-04 03:52:07","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/eaton\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":45367,"post_author":"0","post_date":"2018-12-04 03:40:47","post_date_gmt":"2018-12-04 02:40:47","post_content":"","post_title":"PROCEEDINGS OF THE NUTRITION SOCIETY","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"proceedings-of-the-nutrition-society","to_ping":"","pinged":"","post_modified":"2018-12-04 03:40:47","post_modified_gmt":"2018-12-04 02:40:47","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/proceedings-of-the-nutrition-society\/","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) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The ancestral human diet: what was it and should it be a paradigm for contemporary nutrition?
