Oyster sauce has 2 733 mg sodium per 100 g but only 51 kcal. The low calorie density masks the extreme sodium concentration – a tablespoon (18 g) delivers 492 mg sodium. Condiments are among the most frequently omitted items in food logs (Whitton et al., Adv Nutr 2022). Track every pour in stir-fries.
How should I track Oyster sauce?
Small amounts of Oyster sauce add up faster than most people realize. A systematic review (Whitton et al., Adv Nutr 2022) found that condiments are among the most frequently omitted items in food logs — skipped 1–80% of the time. A tablespoon of mayo or dressing can add 50–100 calories, and most people use two or three tablespoons without measuring. The fix is simple: keep a teaspoon or scale near your plate and measure once. Sauces and dressings are often the hidden reason a "healthy" salad ends up at 600+ calories.
