Balsamic vinegar by itself is relatively low in calories. Even the low-fat balsamic vinegar blended dressings aren’t that high in calories. But when food manufacturers blend it up with high-fat oil to make a balsamic vinaigrette dressing, that’s when you’ll get way more calories than you may realize.
Balsamic Vinegar Salad Dressing has 538 Calories and 46.15 g of Total lipid (fat) per 100 gram serving according to the nutrition facts provided by the USDA Food Composition Database.
Drizzling plain balsamic vinegar on your salad packs on less than 30 calories per 2-tablespoon serving. You can have the same amount of low-fat balsamic vinaigrette dressing for roughly the same amount of calories. If you opt for a full-fat balsamic vinaigrette dressing made with oil, you’ll get three times as many calories -- 90 calories from a 2-tablespoon portion.
