Ultra‐processed food consumption in Argentina according to income level and its association with the intake of healthy foods

Abstract

AbstractUltra‐processed foods (UPFs) are associated with unhealthy diets and chronic diseases. Hence, knowing the consumption pattern of UPFs in the general population is crucial to design policies to improve public health, such as the recently approved law for the Promotion of Healthy Eating in Argentina (Law N° 27.642). The aim of the study was to characterise the consumption of UPFs according to income level and to assess their association with the intake of healthy foods in the Argentinian population. Healthy foods were defined in this study as those non‐UPF groups that have been shown to reduce the risk of non‐communicable diseases and excluded certain natural or minimally processed foods such as red meat, poultry and eggs. We retrieved data from the 2018–2019 National Nutrition and Health Survey (ENNyS 2), a cross‐sectional, nationally representative survey performed in Argentina, including 15 595 inhabitants. We classified the 1040 food items recorded by the degree of processing using the NOVA system. UPFs represented nearly 26% of daily energy. The intake of UPFs increased with income, with a difference of up to 5 percentage points between the lowest (24%) and the highest (29%) income levels (p < 0.001). Cookies, industrial pastries, cakes and sugar‐sweetened beverages were the most consumed UPF items, accounting for 10% of daily energy intake. We found that UPF intake was associated with a decrease in consumption of healthy food groups, mainly fruits and vegetables, where a difference of −28.3 g/2000 kcal and −62.3 g/2000 kcal between tertile 1 and tertile 3 was estimated, respectively. Therefore, Argentina still maintains a UPF consumption pattern of a low‐ and middle‐income country, where UPF intake increases with income, but these foods also compete with the intake of healthy foods.
