Canned tomato sauce has 29 kcal and 564 mg sodium per 100 g. A 125 ml serving adds 36 calories but 705 mg sodium – the sodium is the real tracking concern, not the calories. Store-bought versions vary widely in sodium (200–800 mg per 100 g). Check the label or log the specific brand.
How should I track Tomato sauce, canned?
Small amounts of Tomato sauce, canned 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.
