A low carbon diet refers to making lifestyle choices to reduce the greenhouse gas emissions (GHGe) resulting from energy use.〔(Stacie Stukin, “The Low Carbon Diet,” Time Magazine, Oct. 30, 2006 )〕 It is estimated that the U.S. food system is responsible for at least 20 percent of U.S. greenhouse gases.〔20% of GHGe from food industry〕 This estimate may be low, as it counts only direct sources of GHGe. Indirect sources, such as demand for products from other countries, are often not counted. A low carbon diet minimizes the emissions released from the production, packaging, processing, transport, preparation and waste of food. Major tenets of a low carbon diet include eating less industrial meat and dairy, eating less industrially produced food in general, eating food grown locally and seasonally, eating less processed and packaged foods and reducing waste from food by proper portion size, recycling or composting.〔(Randy Hall, “Low Carbon Diet' Aims to Take Bite Out of Global Warming,” Cybercast News Service, April 18, 2007 )〕 == Overall trends == In a 2014 study by Scarborough et al., the real-life diets of British people were surveyed and their greenhouse gas footprints estimated.〔Peter Scarborough, Paul N. Appleby, Anja Mizdrak, Adam D. M. Briggs, Ruth C. Travis, Kathryn E. Bradbury, and Timothy J. Key, 'Dietary Greenhouse Gas Emissions of Meat-eaters, Fish-eaters, Vegetarians and Vegans in the UK', ''Climatic Change'', July 2014, Volume 125, Issue 2, pp. 179-192, (DOI:10.1007/s10584-014-1169-1 ).〕 Average greenhouse-gas emissions per day (in kilograms of carbon dioxide equivalent) were: *7.19 for high meat-eaters *5.63 for medium meat-eaters *4.67 for low meat-eaters *3.91 for fish-eaters *3.81 for vegetarians *2.89 for vegans 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Low carbon diet」の詳細全文を読む スポンサード リンク
