Entries may come from different FDC data types or releases, and brand or preparation differences can change the numbers.
- Calorie and macronutrient data sourced from the USDA FoodData Central , the federal food composition database used as the main reference where a matching entry exists.
- Daily Value context: for % DV comparisons, use the FDA Daily Value reference amounts for a 2,000 calorie diet (21 CFR 101.9).
- Dietary reference intakes (DRI) for vitamins and minerals are available in the National Academies Dietary Reference Intake tables for further reading; this page does not calculate DRI percentages.
- Glycemic index values are approximate listed values; GI varies by variety, ripeness, and preparation, so compare with the Harvard Health Glycemic Index Reference and the University of Sydney GI database.
- Dietary guidelines context from the HHS/USDA Dietary Guidelines for Americans 2020–2025 , the federal evidence-based nutrition guidance.
