Vinaigrettes are oil-forward. This one runs 449 kcal per 100 g with 50.1 g fat. A 2024 meta-analysis of 30 cohorts in 2.71 million people (Ke et al., Food & Function 2024) found each extra 10 g/day of olive oil cut all-cause mortality by ~8%. The oil base is the nutritional upside.
How should I track Salad Dressing, home recipe, vinegar and oil?
With calorie-dense foods like Salad Dressing, home recipe, vinegar and oil, a kitchen scale is your best friend. Research shows that portion estimation errors reach 50–200% for fats and oils (Almiron-Roig et al., Appetite 2013) — even a tablespoon off can mean 40–120 extra calories. Weigh on a scale rather than eyeballing — this applies to both liquid oils and solid fats like butter. If you use cooking sprays, note that "0 calorie" labels are per fraction-of-a-second spray — a realistic burst is closer to 5–10 calories, and multiple sprays add up.
