All of the nutritional information posted with the recipes on this site are calculated by myself using a recipe software program. All of the data for each ingredient comes from the USDA nutritional information database. The USDA classifies thousands of foods and gives their nutritional breakdown. In cases where an ingredient is not found in the USDA database, I will use the information provided on the product packaging to enter the data into the program.
Please keep in mind that while I try to be as accurate as possible, the nutritional information on this site is approximate and not guaranteed to be 100% accurate.
