Background. Inadequate fruit and vegetable consumption causes a considerable disease burden and premature mortality. Despite considerable public health promotion of a healthy diet the average consumption is still below recommended levels. Fruit and vegetable consumption influences human skin colour, increasing red/yellow/orange pigment in the skin. Given that this colour is deemed attractive and healthy looking, the appearance benefit may provide motivation to eat more fruit and vegetables. Such appearance motivation could be particularly effective in young individuals who currently eat least fruit and vegetables. Objectives. To assess how widely the impact of diet on skin colour is known within the UK. To compare the strength of motivation to eat fruit and vegetables based on health and appearance benefits and to compare the effect of different UK demographics on motivation. Methods. Four groups of UK residents (N = 200 each group) were recruited through the Prolific online platform. Groups comprised younger (aged 18 to 24) and older adults (aged 40 to 60) of low and high self-reported socioeconomic status (1 to 5 and 6 to 10 on a 10 point rating scale). Facial images simulating the skin colour associated with low and high fru...Continue Reading
