Understanding Butter Nutrition
Butter is a dairy food valued for its calcium, protein and fat content. At 714 kcal per 100 g serving, it provides 0.7g of protein, 0.0g of carbohydrate and 79g of fat. Butter is particularly rich in saturated fat, delivering 51.4g — 257% of the daily value — in a single serving. It has no fiber and almost no sugar.
For athletes and anyone tracking macros, butter is calorie-dense and works well for adding calories without added volume, thanks to its fat content. With only 0.1g of protein per 100 kcal, though, it contributes essentially nothing toward a protein target — it's best used to add calories to a meal, not counted as a protein source.
