The Core Difference: Salt
The main difference between salted and unsalted butter is the added salt. Unsalted butter contains only pasteurized cream and a negligible amount of sodium found in milk solids. Salted butter has salt added during production, which acts as a flavor enhancer and preservative. The amount of salt varies by brand, so most baking recipes use unsalted butter to ensure consistent flavor.
Sodium Intake and Heart Health
Too much sodium can increase the risk of high blood pressure, stroke, heart disease, and kidney disease. Unsalted butter helps reduce daily sodium intake. A tablespoon of salted butter can contain 80 to 100 mg of sodium, while unsalted butter has virtually none added. For those at risk of hypertension, choosing unsalted butter is a change with health benefits.
Saturated Fat and Calories
Both salted and unsalted butter have similar amounts of saturated fat and calories. A tablespoon of either contains about 102 calories and 7.2 grams of saturated fat. While unsalted butter is a better choice for sodium management, it should still be eaten in moderation as part of a balanced diet, especially for those watching their saturated fat intake. Healthier fat alternatives like olive oil are often recommended for those seeking to lower overall fat consumption.
Culinary Versatility and Flavor Control
Chefs and bakers prefer unsalted butter for its flexibility and ability to allow other flavors to shine. In baking, unsalted butter allows for the precise measurement of salt, which is critical for consistent results in things like cakes, cookies, and pastries. In savory cooking, unsalted butter allows a cook to season to taste without the risk of over-salting, making it ideal for delicate sauces, sautés, and roasted dishes. The neutrality of unsalted butter enhances the ingredients.

- Read Labels: Always check the nutrition facts, especially for salted butter, as the sodium content varies.
- Control is Key: For precise cooking and baking, unsalted butter is the better choice. It ensures the correct amount of salt.
- Consider Freshness: Unsalted butter is often fresher because of its shorter shelf life.
- Moderation for All: Both salted and unsalted butter are high in saturated fat and calories. Consume both in moderation.
Conclusion: Making a Health-Conscious Decision
Unsalted butter is healthier because it eliminates added sodium, which can negatively impact cardiovascular health, particularly for those at risk. It gives cooks control over seasoning. Saturated fat and calorie profiles remain unchanged. Choose unsalted butter to control sodium, but always consume it in moderation as part of a varied diet. Consult the World Health Organization to learn more about recommended sodium limits.
