Tomato nutrition by serving size

Every serving below is a USDA household measure for this food, a fraction of one, or a unit conversion. Amounts are USDA values scaled by weight; only the Nutrition Facts panel applies the coarser FDA label rounding.

How many carbs are in a tomato?

A medium tomato (123 g) has 4.8 g total carbohydrate, including 1.5 g dietary fiber and 3.2 g total sugars. Carbohydrate minus fiber is 3.3 g.

How much vitamin C is in a tomato?

A medium tomato (123 g) has 17 mg of vitamin C, 19% of the Daily Value. 100 g has 13.7 mg. At 10 to 19% DV per serving, that meets the FDA threshold for a "good source" claim.

How much potassium is in a tomato?

A medium tomato (123 g) has 292 mg of potassium, 6% of the Daily Value. 100 g has 237 mg. That is below the 10% DV a serving needs for a "good source" claim.

How much fiber is in a tomato?

A medium tomato (123 g) has 1.5 g of fiber, 5% of the Daily Value. 100 g has 1.2 g. That is below the 10% DV a serving needs for a "good source" claim.

How much sugar is in a tomato?

Tomato nutrition per 100 grams

100 g of tomato has 18 calories, 0.88 g protein, 3.89 g carbohydrate, 1.2 g fiber, 2.63 g sugars and 0.2 g fat.

Cherry, Roma, beefsteak and heirloom tomatoes

USDA's record is a year-round average for ripe red tomatoes, and this page uses it for the common types. USDA also lists portion weights by type, which you can pick in the serving list:

  • Round (slicing) tomatoes: small, medium and large whole tomatoes, plus slices and wedges.
  • Plum or Roma tomatoes: oval, meaty and less juicy, the usual choice for sauce. One weighs 62 g.
  • Cherry tomatoes: bite-size, about 17 g each.
  • Beefsteak and heirloom: large slicing tomatoes; weigh them and use the per-100 g values.

Raw vs cooked tomatoes

Cooking tomatoes drives off water, so sauce, paste and sun-dried tomatoes pack more calories and carbohydrate into each gram than fresh tomatoes: the same solids are left in less water. Heat also changes individual nutrients in opposite directions: research on cooked tomatoes has found less vitamin C and more measurable lycopene, the red pigment, than in raw ones. USDA keeps separate records for canned, stewed and sun-dried tomatoes, so use the one that matches your ingredient.

Foods made with tomatoes

Should tomatoes go in the refrigerator?

Keep whole tomatoes on the counter until they are fully ripe. Cold stops ripening and can make the flesh mealy and less flavorful, so unripe tomatoes should not be refrigerated. Very ripe tomatoes can go in the refrigerator for a day or two if you let them come back to room temperature before eating. Cut tomatoes belong in the refrigerator.

Labeling salsa, sauce and other tomato products

Enter fresh tomatoes by raw weight in the label generator. For a cooked sauce, the batch loses water as it simmers, so weigh the finished sauce and set servings from that weight; the recipe nutrition calculator accounts for the yield. If you use canned tomatoes, paste or puree, enter those instead of fresh, and include any salt they contain, since canned tomato products often carry added sodium. Serving sizes for salsa and sauces are in the RACC lookup.

Tomato nutrition label for Canada, the EU and the UK

The same serving of tomato, drawn by the label formats other markets require: the Canadian bilingual Nutrition Facts table, the EU nutrition declaration (per 100 g, energy in kJ and kcal, salt instead of sodium) and the UK nutrition information table with reference intakes. The generator switches between these and many more from one recipe.

Frequently asked questions about tomato

How many calories are in a slice of tomato?
A medium slice, about 1/4 inch thick (20 g), has 4 calories. A thick slice (27 g) has 5 and a thin slice has 3.
How many calories are in a cup of cherry tomatoes?
A cup of cherry tomatoes (149 g) has 27 calories and 5.8 g of carbohydrate. One cherry tomato has 3.
Is a tomato a fruit or a vegetable?
Botanically, a tomato is a fruit, because it develops from the flower and holds the seeds. In cooking and in US dietary guidance it is treated as a vegetable, and in 1893 the US Supreme Court (Nix v. Hedden) ruled it a vegetable for import tariffs.
Do Roma tomatoes have different nutrition from round tomatoes?
USDA uses the same raw tomato record for both, so per gram they match on this page. A Roma has less juice and fewer seeds, which is why it is preferred for sauce, and a single Roma (62 g) has 11 calories.
What is a serving of tomato?
This page defaults to 1 medium whole (2-3/5" dia) (123 g), a USDA household measure. The serving size on a packaged food label is set by the FDA reference amount (RACC) for its category, so a product label can use a different amount. The selector above shows every USDA measure for tomato.
Can I use tomato in a Nutrition Facts label calculation?
Yes. Open the generator with tomato added, enter the weight you use, add your other ingredients and the label is calculated from the same USDA record shown here. A label for a product you sell must reflect your actual recipe and finished serving.

Tools and guides for labeling tomato

If you make and sell a product that contains tomato, these free tools cover the next steps.

Source and method

Nutrient values are from USDA FoodData Central, SR Legacy (April 2018 release, public domain), record 170457: "Tomatoes, red, ripe, raw, year round average". Values are stored per 100 g exactly as USDA reports them and scaled to each serving by weight. The Nutrition Facts panel applies the FDA rounding rules in 21 CFR 101.9; tables and text show the scaled amounts at reading precision, so a figure can differ slightly from the panel. A nutrient USDA does not report for this food is shown as not reported, never as a guessed value.

SR Legacy predates the added sugars field. This is a whole or unsweetened food, so added sugars are shown as 0 g. View the USDA record ↗
