The obesity is a public health problem around the world. The overweight leads to the increase of chronic diseases, and poor dietary habits is one of the reasons. An alternative to improve the nutritional quality of the food consumed is the use of nutritional labeling. The aim of this study was to evaluate the importance of labeling information and the components of the nutrition facts when consumers shop. 141 consumers participated in the study using 9-point scales (1: Nothing important / 9: very important). Socioeconomic and lifestyle information were also collected. Data were analised using Principal Component Analysis (PCA). The consumers of the study were female (60%), aged between 18-35 years, high education level (54% had an university degree and /or postgraduate), family income ranged from 1 to 20 minimum wages. Participants reported being the responsible for their family’s food purchase and 55% declared reading food labels. The principal component analysis explained 46. 96% of the variance (PC 1: 31.13 % and PC 2: 15.83 %). The most important items considered by participants were the nutrition facts, ingredient list, preparation method and best before date. Although the nutrition facts had been highlighted by the majority of participants, the salt, sugar and fat content, as well as price presented intermediate importance. The caloric value, vitamin and mineral content, fibers and, in particular, the presence of gluten and lactose were shown to be of little importance in the consumers’ food choice. Different from other studies, brand presented low importance by consumers when buying. It can be concluded that for the group studied, general items related to nutritional information were more important than the specific ones like calories, salt, sugar and fats content, which demonstrates a general concern about food health, higher than the assigned brand or product prices.
