The following guidelines may be useful to you in determining whether you want to resolve a missing food at your site or submit it to NCC as a New Food Request. Missing dietary supplements should be resolved at your site by creating DSAM User Products (see Appendix 8 of the NDSR User Manual (pdf)).
- Review the Data-entry Rules in Appendix 15 of the NDSR User Manual (pdf)..
- Check New Food Backup Files released with the NCC News to see if the food has already been resolved by NCC.
- Identify a similar food in the database and record your decision as a data-entry rule..
- If the missing food is a brand name product, obtain the nutrients on the Nutrition Facts label from the study participant, grocery store, or manufacturer’s website. Identify a similar food in the database and compare its nutrient values with the product’s nutrient values using the following tolerances to determine if the food is a close enough match.
Nutrient tolerances per 100 g product.
| …. | calories | +/- 85.00 kcal | …. |
| …. | protein | +/- 5.00 g | …. |
| …. | total fat | +/- 2.50 g | …. |
| …. | total carbohydrate | +/- 10.00 g | ….. |
| sodium | +/- 100.00 mg | ….. |
If you cannot resolve a missing food at your site submit a New Food Request by completing the New Food Request Form. Resolutions are returned by email as an NDSR backup file within approximately fifteen business days* if nutrient and ingredient information is provided.
If nutrient and/or ingredient information is lacking, a judgement by NCC staff may be made.
*If more than 10 New Food Requests are submitted, allow for approximately 30 business days for the resolutions.
