This review includes relevant twin studies conducted on eating habits and preferences, and on endophenotypes of disordered eating behaviour in general population, non-clinical settings. The twin study design is presented, along with its assumptions and possible applications in aetiological and public health epidemiology. Subsequently, the strategy for the search of the scientific literature and the exclusion criteria are reported. Then, the analysis of the studies included in this review is performed, with a brief description of targeted outcomes, twin model used, sample characteristics and findings. Finally, key messages emerging from the review are highlighted, emphasizing their value for bridging the current gaps in the understanding of determinants of eating behaviour and their mode of action.
