Is the List of Ingredients a Source of Nutrition and Health Information in Food Labeling? A Scoping Review.

Nutrition labelling is any description intended to inform consumers about the nutritional properties of a food product and has focused primarily on nutrients. However, literature has shown that the nutritional quality of packaged foods is not limited to the amount of nutrients, considering that individuals do not consume only nutrients separately, but rather the entire food matrix. Therefore, to analyze the nutritional quality of a packaged food, it is necessary to read its ingredients. This scoping review aims to discuss (1) the list of ingredients as a source of health and nutrition information in food labelling; (2) opportunities to improve the nutrition labeling policies around the world. The study was carried out through a systematic search on Codex Alimentarius meeting reports. Results show that the list of ingredients is used as a source of nutritional and health information on food labelling; however, this label item is not considered in the regulatory field as a nutrition labelling requirement. It is suggested that nutrition labelling be discussed as a tool for food choices in the context of public health from a broader, consistent, convergent perspective, considering the list of ingredients as an item of nutrition labelling requirement to be included in public policies around the world.

Serving Size and Nutrition Labelling: Implications for Nutrition Information and Nutrition Claims on Packaged Foods.

The presentation of nutrition information on a serving size basis is a strategy that has been adopted by several countries to promote healthy eating. Variation in serving size, however, can alter the nutritional values reported on food labels and compromise the food choices made by the population. This narrative review aimed to discuss (1) current nutrition labelling legislation regarding serving size and (2) the implications of declared serving size for nutrition information available on packaged foods. Most countries with mandatory food labelling require that serving size be presented on food labels, but variation in this information is generally allowed. Studies have reported a lack of standardisation among serving sizes of similar products which may compromise the usability of nutrition information. Moreover, studies indicate that food companies may be varying serving sizes as a marketing strategy to stimulate sales by reporting lower values of certain nutrients or lower energy values on nutrition information labels. There is a need to define the best format for presenting serving size on food labels in order to provide clear and easily comprehensible nutrition information to the consumer.
