Canned Tomatoes - How Many Calories?

How many calories are in canned tomatoes?

Ripe red tomatoes canned in tomato juice provide 16 kcal per 100 g, including the liquid. The USDA 240 g cup supplies about 38 kcal; a weighed 400 g amount supplies 64 kcal. These values do not describe drained tomatoes, concentrated paste or a sauce cooked with oil.

Adding a can to a recipe

If you use the entire contents, use the net weight. If you discard the liquid, the drained amount becomes relevant. For example, 400 g of these tomatoes, including their juice, divided between four equal recipe portions contributes about 16 kcal and 115 mg sodium per portion. Oil, pasta, meat and other ingredients must be added separately. The 400 g amount is a weighed example, not a universal can size.

Draining changes the proportion of solids and liquid you eat. This table cannot tell you exactly how much sodium will be removed when you pour away the juice. Use a separate drained-product label or composition entry when available.

The separate generic cooked canned-tomato reference also gives 16 kcal per 100 g, but contains 204 mg sodium. Equal calories do not establish an identical product or salt content; do not replace the sodium of every subsequently cooked can with that figure.

Fiber, potassium and choosing less sodium

Per 100 g, the reference supplies 1.9 g fiber, 191 mg potassium, 0.79 g protein and 115 mg sodium. It adds fiber and potassium along with tomato flavor, but contributes little protein. Low calories do not mean that every canned tomato product is low in sodium. Compare similar labels per 100 g when choosing a lower-sodium option; a no-added-salt product should not inherit the sodium figure in this table. For the drink alone, use the separate tomato-juice nutrition calculation; this entry counts tomato solids and their liquid together.

Storage after opening

Refrigerate opened commercial canned tomatoes in a covered container. USDA's high-acid canned-food storage chart gives 5–7 days after opening; follow a shorter package instruction. Do not use bulging, leaking or badly damaged containers, and do not taste suspect food to decide whether it is safe. Safe home canning requires its own tested process; this nutrition table is not a canning recipe.

The composition reference is USDA SR28 entry 11531. Product labels, varieties and the proportion of liquid can change the result.
