A note about the source of our nutrient facts: Most of the food values on our site (including the ones in the Peanut Brittle nutrition facts label above) were obtained from the United States Department of Agriculture National Nutrient Database for Standard Reference.
Our site uses the same standards for rounding nutrient values as food labels you'll find on cereal boxes and milk cartons. You can find these standards here: Nutrition Label Rounding
Percent daily values
The numbers in the "% Daily Values" section of the food label above are based on a 2,000 calorie diet. Check your DCI to determine if these numbers should be altered for your diet.
