Glycemic Index Values Database

NCI has developed a listing of Glycemic Index (GI) values for individual foods. Food codes from the USDA Continuing Survey of Food Intakes of Individuals (CSFII) are used as a reference. This file provides GI values for those foods consumed by adults and queried on the DHQ or other FFQs used at NCI. The foods listed as having a null value are those to which we did not assign a GI value because they were not important contributors to a food group for which we were calculating a GL value. Two files are provided. The first is organized by CSFII food code. The second is organized by DHQ food groups consistent with line items on the questionnaire.
