A functional food is a food given an additional function (often one related to health-promotion or disease prevention) by adding new ingredients or more of existing ingredients.〔(What are Functional Foods and Nutraceuticals? Agriculture and Agri-Food Canada )〕 "Functional Food is a Natural or processed food that contains known biologically-active compounds which when in defined quantitative and qualitative amounts provides a clinically proven and documented health benefit, and thus, an important source in the prevention, management and treatment of chronic diseases of the modern age". It was debated at the 9th International Conference on "Functional Foods and Chronic Diseases: Science and Practice" at the University of Nevada, Las Vegas on March 15–17, 2011. Functional Food Center (FFC) has adopted a new definition of functional food.〔Danik M. Martirosyan (Ed): Functional Foods and Chronic Diseases: Science and Practice. Food Science Publisher; 2011〕 Functional Food Center defines functional food as "natural or processed foods that contain known or unknown biologically-active compounds; the foods, in defined, effective, and non-toxic amounts, provided a clinically proven and documented health benefits for the prevention, management, or treatment of chronic diseases".〔Martirosyan, D. & Singh, J. A new definition of functional by FFC: what makes a new definition unique? review article. ''FFHDJ''. 2015; 5(6):209–223.〕 According to the United States Department of Agriculture- Agricultural Research Service (USDA –ARS), functional foods are "designed to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, and may be similar in appearance to conventional food and consumed as part of a regular diet".〔Basics about Functional Food.

Accessed: November 17, 2015〕 The term was first used in Japan in the 1980s where there is a government approval process for functional foods called Foods for Specified Health Use (FOSHU).〔(【引用サイトリンク】 agency= Government of Japan )〕 == Industry == The functional food industry, consisting of food, beverage and supplement sectors, is one of the several areas of the food industry that is experiencing fast growth in recent years.〔Roberts, W. "Benefiting Beverages." ''Prepared Foods'' August 2009〕 It is estimated by BCC Research that the global market of functional food industry will reach 176.7 billion in 2013 with a compound annual growth rate (CAGR) of 7.4%. Specifically, the functional food sector will experience 6.9% CAGR, the supplement sector will rise by 3.8% and the functional beverage sector will be the fastest growing segment with 10.8% CAGR.〔 This kind of growth is fueled not only by industrial innovation and development of new products that satisfy the demand of health conscious consumers but also by health claims covering a wide range of health issues.〔Scholan, I. "Functional Beverages-- where next? Innovation in functional beverages market is set to continue." ''International Food Ingredients'' December 2007.〕 Yet, consumer skepticism persists mainly because benefits associated with consuming the products may be difficult to be detected.〔 Strict examination of some of the functional food claims may discourage some companies from launching their products.〔 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「Functional food」の詳細全文を読む スポンサード リンク
