The past few years have seen significant demographic changes in most regions, including an increased elderly population . Subsequently, elderly citizens comprise an important market segment of consumers, with the food industry one of the most affected areas in this context . However, food market managers previously believed that elderly consumers ’ needs were stereotyped in nature . The lack of focus on this sector, therefore, left elderly consumers as an untapped market, without realizing the financial independence of this segment regarding their nutrition . This research will attempt to provide the key determinant factors on elderly consumers ’ behavior related to food . For that purpose, a complete literature review of more than 123 papers regarding these concepts has been carried out . Once analyzed, we highlight the common insights to give clear guidance for supermarket managers and food manufacturers to have a better knowledge of the reasons behind elderly people ’ s food acquisitions.
