Canned Tomatoes (Cooked) - How Many Calories?

Portions of cooked canned tomatoes

The checked generic reference for cooked canned tomatoes provides 16 calories per 100 g. Its 80 g reference portion provides about 13 calories, and a weighed 150 g amount provides 24. It is a plain canned-tomato entry, separate from an oil-based pasta sauce, tomato paste or drained tomatoes.

What changes when tomatoes go into a meal?

Canned tomatoes can form part of a soup, pasta sauce or vegetable dish. Count oil, meat, cheese and other additions separately. Simmering away liquid can change the concentration per gram, so the starting weight should not automatically be treated as the finished sauce weight.

For example, the 24 calories from 150 g of the reference tomatoes is not the calorie count of the whole meal. Include the added ingredients and the fraction eaten. A jar’s gross weight also includes packaging; weigh the food itself. If you drain the tomatoes, use a reference that describes drained solids.

Count tomatoes added to plain cooked pasta as one ingredient of the sauce. Use the pasta’s cooked weight and the separate quantities of tomatoes and any oil, rather than estimating the entire plate from the name “tomato pasta”.

The generic prepared tomato-sauce example gives 27 kcal and 1.53 g fat per 40 g. The same 40 g of the plain canned-tomato reference with its liquid gives about 6 kcal. Using a plain tomato panel for a ready sauce can miss the mixed sauce composition.

Sodium, protein and potassium

A 150 g amount provides approximately 306 mg sodium, 192 mg potassium, 1.46 g protein and 1.56 g fibre. Compare sodium labels at an equal weight. A no-added-salt product may differ from the reference used here; a shared tomato name does not make two panels interchangeable.

Tomatoes contribute flavour and volume to a dish but only a modest amount of protein: approximately 0.98 g per 100 g in the reference. They do not supply the same protein amount as an equal weight of beans or meat.

The separate USDA example for tomatoes canned with their juice gives 115 mg sodium per 100 g, compared with 204 mg in this cooked reference. That difference cannot be attributed to cooking alone: salt and the proportion of solids to liquid can differ between source products.

Source and calculation

Calculations use the Diyetkolik cooked canned-tomato entry of 12.8 calories per 80 g. Brand, cooking time and a drainage analysis are not specified, so no exact evaporation or vitamin-retention factor is assigned. Vitamin A in IU has not been converted to RAE without a valid basis. Unreported sugars remain unknown.
