This vinaigrette carries 771 mg sodium per 100 g. A 2-Tbsp portion adds ~231 mg. A 4.4 g/day salt cut lowers systolic BP by −4.18 mmHg (He et al., BMJ 2013, Cochrane meta-analysis of 34 RCTs). Vinaigrettes are the quiet salt carrier on most salads.
How should I track Italian dressing?
With calorie-dense foods like Italian dressing, 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.
