Features
- Comprehensive food and nutrient database: The NCC Food and Nutrient Database contains values for 155 nutrients, nutrient ratios and food components and includes over 18,000 foods, including ethnic foods and over 8,000 brand products. Ingredient choices and preparation methods provide more than 160,000 food variants.
- Dietary Supplement Assessment Module (DSAM): The DSAM tiered interview approach provides a standardized methodology for NDSR users who wish to collect dietary supplement information. The DSAM utilizes the NHANES Supplement Database with the added feature of a comprehensive ingredient database that provides for the entry of additional user supplement products.
- Food grouping output: NDSR food group serving counts are available for 9 main food groups with 166 subgroups generated into output files.
- Detailed collection of dietary intake data: NDSR provides questions and prompts as information is entered. This optimizes the collection of food detail, preparation methods, and ingredient variables while serving to standardize the entry of intake data.
- Automated amount conversions: Amount conversions permit foods to be described in many forms, such as sliced, grated, or chopped. Other automated amount conversions calculate raw-to-cooked yields, and foods reported with refuse versus edible portion.
- Automated interview: Dietary intake data gathered by interview is entered directly into NDSR. The system searches for foods and brand products by name. Sophisticated search algorithms locate the food and the interview prompts standardize requests for more detail.
- Multiple-pass methodology: Dietary intake data gathered by interview is governed by the multiple-pass approach interview methodology. Four distinct passes provide multiple opportunities for the participant to recall food intake, thereby reducing underreporting.
- Data protection: NDSR protects data by saving information as it is entered. The system provides simple file backup and restore procedures.
- Automated coding and calculation: The coding of foods and their variable ingredients and preparation methods occurs as data are entered. Calculation of nutrients occurs immediately; quantities reported are converted into gram weight and food ID codes are linked with corresponding nutrient values.
- Extensive nutrient data output: Nutrient data are provided at both the whole food and component/ingredient level. NDSR output files permit the ability to distinguish components of a food or ingredients comprising a recipe, as well as identify the whole food. Nutrient data are available per ingredient, per food, per meal or eating occasion, and per daily total.
