How many calories are in one tablespoon of mustard?

One tablespoon of mustard typically contains about 8 calories. This low-calorie count is due to the fact that mustard is primarily made from water, vinegar, and mustard seeds, with very little carbohydrate or fat content. Mustard adds flavor to food without significantly increasing calorie intake, which makes it a popular condiment choice for those looking to reduce caloric consumption. The other options suggest much higher calorie counts than are standard for mustard serving sizes.
