Measuring low-calorie blue cheese dressing

The USDA low-calorie blue or Roquefort cheese dressing reference contains 99 kcal per 100 grams. This is a ready-to-use dressing, not a dry mix. It is distinct from regular dressing and from other products labelled light or fat-free. [1]

How many calories are in one or two tablespoons?

The source assigns 15 grams to a tablespoon, giving 15 kcal. Two tablespoons, or 30 grams, provide 30 kcal and 2.16 g fat. Weigh the dressing if your spoonful varies. Pouring straight from a bottle can add more than the spoonful you have in mind.

Does low calorie also mean low sodium?

It does not for this reference. Sodium is 939 mg per 100 grams, 140.85 mg in a 15 gram tablespoon and 281.7 mg in 30 grams. Two tablespoons are equivalent to about 0.70 grams of salt. Check calories and sodium separately rather than inferring one from the other.

A 30 g amount of regular honey mustard dressing provides about 139 calories and 0.38 g salt. The same weight of this low-calorie blue cheese reference has about 0.70 g salt; less energy does not guarantee less salt.

What about carbohydrate and sugar?

Per 100 grams, the dressing has 2.9 g carbohydrate and 2.82 g sugar. A 30 gram portion supplies 0.87 g carbohydrate and about 0.85 g sugar. The source reports zero fibre. These figures do not describe every blue cheese dressing, so read the label on the product you buy.

How does the dressing fit into a salad?

Measuring the dressing helps you track the energy added to a salad. Count extra oil, cheese or croutons too. A low-calorie dressing does not change the energy supplied by those ingredients. This dressing table alone cannot establish the calories of a whole salad or promise weight loss. If you make another dressing, see how oil counts in a wine-vinegar dressing; adding vinegar does not reduce the oil’s energy.

Which information should you use for a brand?

These figures come from a historical, generic USDA SR28 low-calorie dressing entry. They do not guarantee the composition of a brand's current recipe or a homemade mayonnaise-based dressing. Compare your actual label at the weight you plan to serve.
