When it comes to condiments, you have a lot of choices -- but many of them are high in fat and calories and low in nutritional value or flavor. One option, Dijon mustard, which originally hails from Dijon, France, might not have a lot of nutrients, but it does pack a wallop of sharp flavor for very few calories.
For every tablespoon of mustard you drizzle on your hot dog or spread on your sandwich, you'll add just 15 calories to your meal. Compare this to ketchup, which offers just over 19 calories per tablespoon, or mayo with 94 calories per tablespoon. Dijon mustard doesn't contain a significant amount of fat, carbohydrates or protein, nor does it offer any fiber or sugar. The only other nutrient in Dijon is sodium; each teaspoon contains approximately 120 milligrams. Limit your sodium intake to 2,300 milligrams a day, in accordance with U.S. Department of Agriculture guidelines.
