How to read this number
Raw-food references are still affected by variety, cooking method, edible portion, and exact weight, so weigh the food when precision matters.
Raw and minimally processed food references are anchored to USDA FoodData Central where possible. Prepared foods use transparent recipe models until an exact brand, restaurant, or lab-tested entry is available.
