A Closer Look at the Macronutrient Profile of Butter
When we ask what are the macros for 1 tablespoon of butter, the answer reveals a very clear and simple profile. At its core, butter is a fat, and its macronutrient composition reflects this. A typical tablespoon (about 14 grams) is almost exclusively composed of fat, with negligible amounts of carbohydrates and protein.
The Fat Content
The most significant component of butter is fat, which accounts for approximately 80% of its total weight. In a standard 1-tablespoon serving, you can expect around 11.5 to 12 grams of total fat. This fat is a complex mixture of over 400 different fatty acids, though the primary types are saturated and monounsaturated fats.
- Saturated Fat: This is the most prevalent type of fat in butter, constituting about 7 grams per tablespoon. The saturated fat found in butter includes short-chain fatty acids, like butyric acid, which some studies suggest may have anti-inflammatory benefits.
- Monounsaturated Fat: A tablespoon of butter contains around 3 grams of monounsaturated fat. These fats are generally considered healthier than saturated fats, though they are not the main component here.
- Polyunsaturated Fat: Only a small fraction of butter's fat content comes from polyunsaturated fats, typically less than 0.5 grams per tablespoon.
Negligible Carbohydrates and Protein
For those on low-carb or ketogenic diets, butter is a highly sought-after ingredient because its carbohydrate content is virtually zero. In fact, a single tablespoon contains less than 0.1 grams of carbohydrates and sugars, making it a perfect fat source for maintaining ketosis. Similarly, the protein content is minimal, with most sources reporting it to be around 0.1 grams per tablespoon. This is because butter is made by separating the milk fat from other milk components, which removes most of the protein in the process.
Vitamins and Minerals
While not a macronutrient, it is worth noting that butter also provides some fat-soluble vitamins. The most notable is Vitamin A, with one tablespoon providing over 10% of the recommended daily intake. It also contains smaller amounts of Vitamins D, E, and K2. However, since butter is typically consumed in small quantities, its overall contribution to your total daily vitamin intake is limited.
Comparison Table: Butter vs. Common Alternatives
| Nutrient (per tbsp) | Butter (Salted) | Olive Oil | Margarine (Vegetable Oil Spread) |
|---|---|---|---|
| Calories | ~102 kcal | ~119 kcal | ~100 kcal |
| Total Fat | ~11.5 - 12 g | ~13.5 g | ~11 g |
| Saturated Fat | ~7 g | ~2 g | ~2-3 g |
| Carbohydrates | <0.1 g | 0 g | ~0 g |
| Protein | ~0.1 g | 0 g | ~0.1 g |
Understanding the Calorie Density
At roughly 102 calories per tablespoon, butter is a calorie-dense food. Its high-fat nature means that a small amount provides a significant number of calories. For those managing weight or on a specific calorie-restricted diet, understanding this high-density caloric nature is important for portion control. However, when used in moderation as part of a balanced diet, the calorie density is not a concern for most people.
The Role of Salted vs. Unsalted Butter
The macronutrient profile of salted versus unsalted butter is virtually identical, with the primary difference being the sodium content. A tablespoon of salted butter can contain around 90 mg of sodium, while unsalted butter has negligible amounts. For those monitoring sodium intake, unsalted butter is the clear choice. The trace minerals and fat content remain consistent across both versions.
Conclusion: Butter as a High-Fat, Low-Carb Staple
In summary, what are the macros for 1 tablespoon of butter? The answer is simple: predominantly fat, with minimal protein and virtually no carbs. This profile makes it a highly valuable and versatile ingredient, especially for those following dietary plans like the ketogenic diet. While high in calories due to its fat content, butter is also a source of important fat-soluble vitamins. For most people, consuming butter in moderation as part of a varied and balanced diet can be a delicious and beneficial addition. Always consider your overall dietary needs and health goals when incorporating high-fat foods into your meals.

Where does butter come from, and how is it made?
Butter is a dairy product made by churning fresh or fermented cream or milk to separate the fat globules from the buttermilk. The process breaks the membranes around the milk fat, allowing the fat to clump together and form a solid mass.
Are there any health benefits to butter?
Yes, in moderation. Butter from grass-fed cows contains beneficial fatty acids like conjugated linoleic acid (CLA), which has been studied for its potential effects on weight loss and cancer prevention. It also provides fat-soluble vitamins A, E, D, and K2.
How does the macro count differ in European-style butter?
European-style butter typically has a higher butterfat content, sometimes reaching 82-84% compared to the standard 80% in American butter. This results in a slightly higher fat and calorie count per tablespoon, and a richer flavor and creamier texture.
Is butter suitable for a keto diet?
Yes, butter is an excellent food for the ketogenic diet because it contains high levels of fat and virtually no carbohydrates, which helps maintain the state of ketosis. It is used to add fat to meals and increase satiety.
Can lactose-intolerant people eat butter?
Many lactose-intolerant people can tolerate butter. The churning process removes most of the milk solids, including the milk sugar lactose. However, individuals with severe milk allergies should still avoid it, as trace amounts of milk proteins remain.
How does butter compare to margarine in terms of macros?
While butter is predominantly saturated fat from milk fat, margarine is made from vegetable oils and is typically higher in unsaturated fats, though some contain high levels of saturated fats like palm oil. The total calorie and fat content per tablespoon are often very similar.
Does grass-fed butter have different macros?
Grass-fed butter has a very similar macronutrient profile to regular butter but is known to contain higher levels of certain nutrients, including Vitamin A, Beta-carotene, and Omega-3 fatty acids. The primary macros, however, are essentially the same..
