Butter
What it is
Butter is a dairy fat used in cooking and as a spread. This profile describes unsalted butter.
What it does
For the named reference food, USDA lists 717 kcal, 0.85 g protein, 81.1 g total fat and 24 mg calcium per 100 g edible portion. The table gives additional nutrients for that same food form. These figures describe composition, not an effect on a disease or a recommended serving.
Research context and ingredient forms
Reference food: Butter, without salt. These are historical SR Legacy data from the April 2018 release, published in FoodData Central in 2019. A different variety, preparation, water content, or commercial recipe can change the result. For a matching food, a portion estimate scales each value by edible portion grams divided by 100.
Using this information
A usual butter portion is much smaller than 100 g. Salted butter, clarified butter, and blended spreads need separate labels or records; milk-food protein values do not transfer to butter.
Considerations
This is a milk-derived food. Milk is a major food allergen; use the ingredient and allergen labeling rather than the nutrition table to assess a packaged product.
