| summary | Ultra-processed food consumption has been recently associated with the prevalence of obesity and non-communicable chronic diseases such as some types of cancers, diabetes and heart diseases. However, ultra-processed food consumption is not so-well documented across individuals or across food product categories. In this paper, we construct a unique longitudinal dataset, between 2002 and 2015, of at-home food consumption of French households to which we merge information regarding nutritional values and degree of food processing. Over the period, we find increasing consumption patterns of ultra-processed products, yet still relatively low when compared to Anglo Saxon countries levels of consumption. French lower consumption levels are most likely a result of higher prices for ultra-processed products relatively to less-processed products, the reverse of Anglo saxon prices. We then develop a panel data econometric analysis to identify the determinants of ultra-processed food consumption exploiting the within- and between-household variations. We find that socio-economic demographics would explain more the between household variation that the within-household variation. In fact differences between households are due to obesity status, youth, poverty, rural, north and east location which are all associated with higher levels of ultra-processed consumption. Nonetheless, becoming old, obese, or moving does not have a strong impact in UP consumption. Some life events with impact in time constraint, such as having young children, return to labour activity, or becoming single, are associated higher UP consumption. Yet, the main driver for within-household UP consumption reduction are prices. These results suggest that policies aiming at decreasing UP consumption should , on the one hand, focus on specific population groups and, on the other hand, use price reductions as lever for within household change of consumption patterns. |
