摘要

Food insecurity remains a key public health concern because it is often linked to poorer dietary outcomes. However, there is limited evidence on the behavioural mechanisms through which it influences nutrition information use and diet perceptions. This study examined how nutrition label use and diet self-assessment vary across food security levels in Taiwan. Survey data from 508 adults were analysed using regression models. Results showed that most people engaged selectively with labels, with only 17.2% reading all details. Frequent label users were more likely to report healthier diets. Label engagement was significantly lower in two- and three-person households than among those living alone (OR = 0.53, 95% CI: 0.31–0.92; OR = 0.46, 95% CI: 0.26–0.81). Food security was strongly associated with label use. Full label reading dropped from 17.6% among food-secure individuals to 9.1% among the severely food-insecure. Complete non-reading more than doubled along this gradient. Similar patterns were found in diet self-assessments, with food-insecure individuals over three times more likely to rate their diets as unhealthy. These findings suggest that low nutrition information use may be a pathway through which food insecurity affects diet quality. Addressing this gap could support healthier, more equitable food choices.
