{"title":"Application of acceptability in dietary optimisation models: a systematic review.","authors":"Cathrine Baungaard, Magaly Aceves-Martins, Graham Horgan, David Little, Jonathan Hillier, Baukje de Roos","doi":"10.1017/S1368980026102717","DOIUrl":"10.1017/S1368980026102717","url":null,"abstract":"<p><strong>Objective: </strong>Diet optimisation models have been developed to deal with the complexities of designing a sustainable diet. Diet acceptability is one aspect of a sustainable diet that has had limited integration into these models.

Definitions of acceptability varied considerably. Analysis of the studies found six overarching themes were used to define acceptability in diets, with minimisation of deviation from observed diet and setting of lower and upper bounds on intake being most commonly used. Only 25 % of studies assessed the impact of acceptability models, objective functions and/or constraints, on the dietary output to some degree. Assessing three pathways (deduction, translation and induction) for defining and operationalising acceptability presents new opportunities to include citizens in the development of acceptable dietary models.</p><p><strong>Conclusions: </strong>Including acceptability into diet optimisation models is imperative as they can influence dietary structure, nutritional content, price and environmental impact, although they present certain trade-offs compared to other optimisation goals.
