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. (Both tables are available combined in an MS Excel file.)
