Spaghetti with sauce has 100 kcal per 100 g. The sauce hides 5–15 g of added oil per serving that the eyeball misses. Sodium runs 280 mg per 100 g — most of it from the sauce, not the pasta. Weigh both components when possible.
How should I track Spaghetti, with meatballs in tomato sauce, canned?
Prepared foods like Spaghetti, with meatballs in tomato sauce, canned can be tricky to track because the actual serving you get often differs from the label. Restaurant and deli portions are typically 30–50% larger than the stated serving size. A meta-analysis of dietary reporting (Wehling & Lusher, Am J Clin Nutr 2021) found that people underreport calorie intake by 25–30% on average — and prepared meals are a major contributor. The safest approach: weigh your actual portion as served. Also note that homemade and store-bought versions of the same dish can differ significantly in calories due to cooking methods and ingredients used.
