FoodEx2 Harmonization of the Food Consumption Database from the Italian IV SCAI Children's Survey.

Estimating the habitual food and nutrient intakes of a population is based on dietary assessment methods that collect detailed information on food consumption. Establishing the list of foods to be used for collecting data in dietary surveys is central to standardizing data collection. Comparing foods across different data sources is always challenging. Nomenclatures, detail, and classification into broad food groups and sub-groups can vary considerably. The use of a common system for classifying and describing foods is an important prerequisite for analyzing data from different sources. At the European level, EFSA has addressed this need through the development and maintenance of the FoodEx2 classification system. The aim of this work is to present the FoodEx2 harmonization of foods, beverages, and food supplements consumed in the IV SCAI children's survey carried out in Italy. Classifying foods into representative food categories predefined at European level for intake and exposure assessment may lead to a loss of information. On the other hand, a major advantage is the comparability of data from different national databases. The FoodEx2 classification of the national food consumption database represented a step forward in the standardization of the data collection and registration. The large use of FoodEx2 categories at a high level of detail (core and extended terms) combined with the use of descriptors (facets) has minimized information loss and made the reference food categories at country level comparable with different food databases at national and international level.

Development of Dietary Supplement Label Database in Italy: Focus of FoodEx2 Coding.

The sector of food supplements is certainly varied and growing: an ever wider offer of new products is launched on the market every year. This is reflected in new reorganization of drug companies and new marketing strategies, in the adoption of new production technologies with resulting changes in dietary supplements regulation. In this context, information on composition reported in labels of selected dietary supplements was collected and updated for the development of a Dietary Supplement Label Database according to products' availability on the Italian market and also including items consumed in the last Italian Dietary Survey. For each item, a code was assigned following the food classification and description system FoodEx2, revision 2. A total of 558 products have been entered into the database at present, trying to give a uniform image and representation of the major classes of food supplements, and 82 descriptors have been compiled. Various suggestions on how the number of FoodEx2 system descriptors could be expanded were noted during the compilation of the database and the coding procedure, which are presented in this article. Limits encountered in compiling the database are represented by the changes in the formulation of products on the market and therefore by the need for a constant database update. The database here presented can be a useful tool in clinical trials, dietary plans, and pharmacological programs.

From Plant Compounds to Botanicals and Back: A Current Snapshot.

This work aims at giving an updated picture of the strict interaction between main plant biologically active compounds and botanicals. The main features of the emerging class of dietary supplements, the botanicals, are highlighted. Focus is also on the definition of actual possibilities of study approach and research strategies. Examples of innovative directions are given: assessment of interaction of bioactive compounds, chemometrics and the new goal of biorefineries. Current models of existing databases, such as plant metabolic pathways, food composition, bioactive compounds, dietary supplements, and dietary markers, are described as usable tools for health research. The need for categorization of botanicals as well as for the implementation of specific and dedicated databases emerged, based on both analytical data and collected data taken from literature throughout a harmonized and standardized approach for the evaluation of an adequate dietary intake.

Assessment of dietary intake of 10 intense sweeteners by the Italian population.

The aim of the present study was to monitor the consumption of foods containing intense sweeteners present on the Italian food market and to investigate whether the Italian general population (aged >3-65+) was at risk for exceeding the Acceptable Daily Intake (ADI) of 10 intense sweeteners. A food label survey was performed in Rome (Italy), using market share data to identify the brands more representative of the market. A sample of 326 foods (table-top sweeteners included), beverages and food supplements containing intense sweeteners was collected and analyzed in order to establish the concentration levels. Intense sweeteners were only found in foods belonging to 8 sugar-free food categories out of 37 regulated. The dietary exposure was estimated using the tiered approach. Food consumption data from the last Italian national survey (INRAN-SCAI 2005-06) were combined with Maximum Levels at Tier 2, and with the actual concentration of sweeteners in the collected food products at Tier 3. The estimated exposure among consumers of sweeteners in Italy was well below the ADIs, in both tiers; non-alcoholic beverages, table-top sweeteners and food supplements were main contributors to exposure.

The third Italian National Food Consumption Survey, INRAN-SCAI 2005-06--part 1: nutrient intakes in Italy.

BACKGROUND AND AIMS: Italian National Food Consumption Survey, INRAN-SCAI 2005-06, is the third national food consumption survey performed in Italy. This study describes energy and nutrient intakes in Italy. METHODS AND RESULTS: A national cross-sectional food consumption survey was conducted using consecutive 3-day food records between October 2005 and December 2006. A sample of 3323 males and females aged 0.1-97.7 years living in private households was investigated. Individual food records were converted into energy and nutrient intakes with the use of recently updated national food composition databases. For each subject, intakes of energy and of 27 nutrients were calculated, including six minerals (i.e., iron, calcium, phosphorus, magnesium, potassium and zinc) and 10 vitamins (i.e., thiamine, riboflavin, vitamin C, vitamin B6, retinol, ß-carotene, vitamin A as retinol equivalents (REs), vitamin E, vitamin D and vitamin B12. On average, 36% of calories appeared to derive from fat (11% from saturated fatty acids) and 45% from available carbohydrates (15% from soluble carbohydrates). CONCLUSIONS: The results of the INRAN-SCAI 2005-06 survey in terms of nutrient intakes provide an important piece of information for nutrition surveillance of the population and may also be used to identify priorities for further research.
