“…This finding relates to a number of studies carried out on the aetiology of food preferences in children including biological factors such as genetic predispositions and evolutionary derived preferences for food high in sugar and fat (Birch & Fisher, 1998; Mennella, Bobowski, & Reed, 2016) in addition to other, social psychological antecedents, arguably more amenable to change. These include attitudinal, social and economic variables (Drewnowski, 1997), individual differences such as fussiness, enjoyment of food and food responsiveness (Russell & Worsley, 2016), extensive and irresponsible marketing aimed at children (Boyland & Halford, 2013) and parental control behaviours which reinforce consumption of snack or treat food (usually high in sugar or fat) in non-food contexts (Lu, Xiong, Arora, & Dubé, 2015). This literature has particular resonance with participants’ descriptions of children’s food-related behaviours as “picky” or “fussy”, and older children in particular becoming increasingly influenced by marketing and advertising of fast food.…”
