Sodium

Methods

Data on packaged food was obtained from the Composition and Labelling Information System (CLIS) database, which uses a smartphone application for nutrient data collection and management. Data was collected from the three major grocery chains in Slovenia’s capital, Ljubljana: Spar, Mercator and Hofer. All pre-packaged products in the store were systematically photographed and recorded in the CLIS database. Information such as product name, company, brand, list of ingredients, nutritional values, packaging volume, price and European/International Article Number were collected. Products were then sorted into 40 categories according to the Global Food Monitoring Initiative.

Researchers calculated the average sodium content available and sodium content sold among packaged foods (in mg of sodium per 100 g/mL.) For the global nutrition database, we extracted the sodium content for packaged foods available, not sold.

Methods

Data on packaged food was obtained from the Composition and Labelling Information System (CLIS) database, which uses a smartphone application for nutrient data collection and management. Data was collected from the three major grocery chains in Slovenia’s capital, Ljubljana: Spar, Mercator and Hofer. All pre-packaged products in the store were systematically photographed and recorded in the CLIS database. Information such as product name, company, brand, list of ingredients, nutritional values, packaging volume, price and European/International Article Number were collected.

Products were then sorted into 49 food categories for which mean values, standard deviation, median, interquartile range and minimum and maximum values were calculated for the total and free sugar content (g/100g/ml of product). Sales-weighted total/free sugar contents were calculated on the food category level (in g /100g/mL). The study also calculated the average amount of free sugar in an individual food category and reported it as a percentage of the averaged total sugar content of the group; this figure is not included in database. Data reported in Global Nutrition Database is the sales weighted total sugar content for packaged foods included in the sample.

Methods  

Datasets were generated by a standard food monitoring study of the major food retailers with the largest nationwide shop networks, covering most of the food supply. All available prepacked products were systematically photographed and entered into a national database program, the Composition and Labelling Information System (CLAS). European Article Number (EAN) barcodes were used as product identifiers. The collection of the food photographs in the food stores was conducted using the CLAS mobile application, and further data processing was conducted on the application’s web platform. Data on sodium content (median and IQR) were collected from the photographs for the purpose of this study. The 2017 dataset contained 11,595 products, while the 2020 dataset contained 12,302 products. The foods were categorized according to the recommendations of the Global Food Monitoring Group, with minor adaptations when considering the specifics of the European market.
