Where to Find Carbohydrate Factors

No master list of carbohydrate factors has been published, but the USDA Nutrient Database can provide much of the information you need, and some partial lists have been published. However, because different lists may use different sources of nutrient information, you may notice slight variations in carbohydrate factors.

USDA Nutrient Database
www.nal.usda.gov/fnic/foodcomp/search
This database lists more than 6,500 items, including processed, packaged, and fresh foods. To find carbohydrate factors using this database, first search for the food you want and select an amount of 100 grams. Scroll down the resulting table to “Carbohydrate, by difference” and note the “Value per 100 grams of edible portion.” Divide that number by 100 (or move the decimal point two places to the left), and you have the carbohydrate factor for the food.
