Low-fat dressings look healthy at 160 kcal per 100 g. A 2024 meta-analysis of 16 RCTs in 27,710 people (Greenwood et al., Ann Intern Med 2024) found salt substitution cut all-cause mortality by 12% and cardiovascular mortality by 17%. When fat comes out, salt usually goes up.
How should I track Creamy dressing, made with sour cream and/or buttermilk and oil, reduced calorie?
With calorie-dense foods like Creamy dressing, made with sour cream and/or buttermilk and oil, reduced calorie, 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.
