Introduction: helping consumers to know what they eat represents a communication challenge. Objectives: to evaluate the level of understanding of the information contained in a nutritional label in Venezuelan adult consumers, and their eventual ability to extrapolate said data in making purchase decisions related to a balanced and healthy diet. Methods: a descriptive cross-sectional study in which 377 people participated through a questionnaire with eight open questions, focused on the general use and perception of nutritional labeling, as well as the ability to interpret the information contained therein. Results: The 77.45% of the sample valued finding the nutritional information on the packaging of a product as very important. Middle-aged women read the nutritional information the most. In general, the performances on the understanding of the information of the nutritional table were very poor, and the only demographic variable studied strongly associated with its understanding was the educational level of the participants. Conclusions: a high percentage of people are unable to understand nutrition labeling information, representing a challenge for the evolution to more efficient labeling systems and consumer nutrition literacy programs.

Objectives. To estimate the number of processed and ultra-processed beverages and foods that provide nutritional information on their packaging, and to describe the characteristics of this information, as well as to determine the presence of nutritional information on products with octagons. Materials and methods. Photographs were taken of the labels of 4404 processed and ultra-processed beverages and foods marketed in supermarkets in Metropolitan Lima. The information on the label was collected and registered in the mobile and web version of the Food Label Information Program (FLIP). We analyzed
variables related to the nutritional information, the way in which such information is declared and the information in beverages and foods with octagons. Results. Only 71.4% of the products had some type of nutritional information. Of these, 13.8% provided the nutritional information as a text and not in a table, and only 56.3% declared it per 100 grams or milliliters. Of the total number of foods with the
octagon “Contains trans fats”, only 19.2% declared their content. Conclusions. More than a quarter of the beverages and packaged foods in the Peruvian market did not provide nutritional information of any kind, and of those that did, only one did so in different formats and units. In addition, we found that a proportion of beverages and foods for each type of octagon did not declare information of the nutrient
that is mentioned in the octagon.
