The Macronutrient Profile of 50 Grams of Butter
Butter's nutritional profile is remarkably straightforward, consisting almost entirely of fat. For a typical 50-gram serving, the macronutrient breakdown is dominated by lipids, with minimal contributions from protein and virtually none from carbohydrates. This makes it a high-calorie, zero-carb food source, which is especially relevant for those on low-carb diets.
Fat Breakdown: The Dominant Macronutrient
The most prominent macronutrient in butter is fat, with a 50g serving containing approximately 40.5 to 41 grams. This isn't just one type of fat but a complex mixture of various fatty acids. Breaking down the total fat content reveals:
- Saturated Fat: About 25 to 26 grams, making up the largest proportion of butter's fat. Saturated fats are solid at room temperature and contribute to butter's creamy texture.
- Monounsaturated Fat: Roughly 10 to 11 grams. These fats are generally liquid at room temperature and are often linked to heart health benefits when consumed in moderation as a replacement for saturated fats.
- Polyunsaturated Fat: Approximately 1.5 to 2 grams. This category includes beneficial omega-3 and omega-6 fatty acids, though the quantity in butter is relatively small compared to other sources like nuts or seeds.
Minimal Carbs and Protein
In a 50g serving, the amount of carbohydrates is negligible, often listed as 0 grams or only a trace amount. This is because butter is primarily the milkfat that has been separated from other milk solids. Similarly, the protein content is minimal, typically around 0.4 grams, derived from the tiny remaining milk solids. Therefore, butter is not a meaningful source of either carbs or protein in a diet.
Macro Comparison: Butter vs. Alternatives
For those considering alternatives or different butter types, comparing their macro profiles can be helpful. The table below illustrates the contrast between regular butter, ghee, and whipped butter per 50-gram serving, based on nutritional data.
| Nutrient | Regular Butter (Salted) | Ghee (Clarified Butter) | Whipped Butter (with Salt) |
|---|---|---|---|
| Calories | ~359 kcal | ~438 kcal | ~359 kcal |
| Total Fat | ~41 g | ~50 g | ~41 g |
| Saturated Fat | ~26 g | ~31 g | ~25 g |
| Protein | ~0.4 g | ~0.1 g | ~0.4 g |
| Carbohydrates | ~0 g | ~0 g | ~0 g |
Different Kinds of Butter
The macro profile can shift slightly depending on the type of butter. Whipped butter has air or nitrogen incorporated, increasing its volume and resulting in slightly fewer calories and fat per tablespoon compared to its solid counterpart. Ghee, or clarified butter, has the milk solids and water removed, concentrating the fat content and giving it a higher smoke point suitable for frying. Additionally, grass-fed butter can have a different fatty acid composition, with studies suggesting higher levels of beneficial conjugated linoleic acid (CLA) and potentially a more favorable omega-3 to omega-6 ratio.
Culinary and Dietary Considerations
Because butter is so rich in calories and fat, moderation is key for any healthy eating plan. A 50g serving, which is roughly 3.5 tablespoons, represents a significant portion of an average person's daily fat and calorie intake. For individuals managing heart disease or watching their weight, it is especially important to be mindful of portion sizes. Butter is particularly useful in keto or low-carb recipes for adding richness and a high-fat energy source without adding carbohydrates. It is also an excellent cooking medium for its flavor and stability at high temperatures, particularly ghee. When adding butter to dishes, consider it a flavour enhancer rather than a primary nutrient source. Using it alongside other healthy fats like olive oil can provide a more balanced profile.

Conclusion
In summary, 50 grams of butter is primarily composed of approximately 41 grams of fat and contains about 358 calories. The fat is a mix of saturated, monounsaturated, and polyunsaturated types, with saturated fat being the most prominent. It provides negligible protein and virtually no carbohydrates. While a rich source of fat-soluble vitamins and a useful culinary ingredient, its high calorie and saturated fat content mean it should be used in moderation, especially for those concerned with managing weight or cardiovascular health. Choosing specific types like grass-fed or mindful portioning can help incorporate this flavorful ingredient into a balanced diet.
