The expansion of marketing and consumption of ultra-processed foods and beverages proceeds jointly with the increase in prevalence of overweight, obesity and other chronic diseases related to improper nutrition and insufficient physical activity in almost every country (SWINBURN et al., 2011; MONTEIRO et al., 2013). Several studies point to potential connections between the current pandemic in noncommunicable diseases related to obesity and the recent changes in food production and distribution structures worldwide, especially due to intrinsic characteristics of ultra processed food and beverage products that favor overconsumption: convenience, price and flavor. However, ultra-processed foods and beverages are also marked by low nutritional quality (MONTEIRO et al., 2013; LOUZADA et al., 2015a,b,c). Changes in food supply systems are related to greater availability of ultra processed food products in populations’ diets, especially considering the rise of large supermarket chains and the concentration of household food acquisition at supermarket retail stores (SWINBURN et al., 2011; REARDON & TIMMER, 2012; MONTEIRO et al., 2013; COSTA et al., 2013; GÓMEZ; RICKETTS, 2013; POPKIN, 2014; STANTON, 2015; TAILLIE, NG, POPKIN, 2016). Besides the aggressive massive advertisement for ultra-processed products on the TV, magazines and other media platforms, consumers are constantly induced to purchase large volumes of ultra processed foods and beverages at supermarkets through pricing policies, constant introduction of new products, promotions and elaborate marketing strategies involving priority placement that allows more exposure of those products on shelves, among other things (HAWKES, 2008; REARDON & TIMMER, 2012; STANTON, 2015; STERN; NG; POPKIN, 2015).
