The Version of Record is available online at: https://doi.org/10.1007/s12062-024-09475-4This article presents a systematic review (SR) of the literature examining how loneliness and social isolation1 could mediate dietary choices among older adults. The review focuses on qualitative and mixed-methods research studies published between 2013 and 2023. The results reveal the impact of loneliness on three main areas: (1) how changes to a household affect dietary behaviour and appreciation of food; (2) the strategies that older people implement to regain or reconstruct commensality; and (3) living alone as an opportunity for exercising a greater degree of autonomy and control regarding food choices.engjournal article10.1007/s12062-024-09475-4open access
