The aim of this study was to evaluate the effect of warning label, brand, and claims on Brazilian consumers' perceived healthiness. Four product categories were considered: chocolate flavored milk, granola, iced tea, and cookies. A total of 893 Brazilian consumers took part in an online survey. For each product category, a series of packages were designed considering the following 2-level factors: brand (well-known vs. unknown), warning (presence vs. absence), visual claim (presence vs. absence) and textual claim (presence vs. absence). Two independent data collection was carried out, which corresponded to two warning labels with different graphic design: black magnifier glass (n= 448) and black octagon (n= 445). Participants were presented with eight pairs of packages and were asked to select the healthiest product in each pair. Data were analyzed using a random parameters logit model. For both studies, the warning had a negative effect on consumer healthiness perception for all product categories, while the other factors had positive effects. These results suggest that the presence of the warnings reduced perceived healthiness. On the contrary, the well-known brand and the inclusion of textual and visual nutritional marketing claims increased perceived healthiness. The relative importance of brand and textual nutritional marketing claims was higher than that of nutritional warnings. These results demonstrate the effectiveness of nutritional warnings and indicate the need to regulate claims for strengthening FOPNL policy in the Brazilian context.  aConjoint Analysis  aConsumer studies  aFront-of-pack nutrition labelling1 aALCANTARA, M.
