A cup is 41 calories, five cups only 207
Portions barely move the calorie total here. A 6 fl oz (182 g) can, the size many people grab from a multipack, comes to 31 calories. A full 1 cup (243 g) glass is 41, which is 2% of a 2000-calorie daily value. Even at 100 g you are looking at 17 calories and 1% of the day.
Scale it up and the energy still stays small. Two cups (486 g) land at 83 calories, three cups (729 g) at 124, and five cups (1,215 g) at 207. Few drinks let you pour more than a liter and stay near the calorie count of a single snack bar.
So the portion question for tomato juice is really a sodium question. The same five cups that add only 207 calories also carry 3,074 mg of sodium. If you drink it by the glass, calories are an afterthought. If you drink it by the bottle, read the next section first.
Carbs supply 70% of the calories
Tomato juice is mostly water, so the few calories it has come largely from carbohydrate. Carbs make up 70% of the energy, protein 17% and fat 13%. Per 100 g that works out to 3.5 g of carbs, 0.9 g of protein and 0.3 g of fat, with 0 g of saturated fat and 0 mg of cholesterol.
A cup gives you 8.6 g of carbs, and 6.3 g of that is sugar from the tomatoes themselves. Fiber is modest at 1 g per cup, or 0.4 g per 100 g. Protein reaches 2.1 g per cup, which is 4% of the daily value, so do not count on this glass to keep you full on its own.
The upside of that profile is predictability. There is no fat to speak of and the sugar is lower than in most fruit juices, so a glass slots into nearly any eating plan without crowding out other foods. Potassium shows up too, at 217 mg per 100 g.
Sodium is the row to watch
The standard canned juice with salt added carries 253 mg of sodium per 100 g. That turns into 460 mg for a 6 fl oz can (20% of the daily value) and 615 mg for a cup (27%). For a drink with 41 calories, that is a lot of salt per sip.
It stacks quickly. Two cups bring 1,230 mg, three cups 1,844 mg, and five cups 3,074 mg, which is more than a full day's daily value from juice alone. If you pair a glass with a salty breakfast or a deli sandwich, the sodium row climbs faster than the calorie row ever will.
The fix is simple and costs nothing in calories. The no salt added version has the same 41 calories, 8.6 g of carbs and 6.3 g of sugar per cup, but only 24 mg of sodium, or 1% of the daily value. Campbell's sells a low sodium 100% tomato juice, and organic lines such as R.W. Knudsen are worth checking on the label too.
A low-calorie glass that needs company
Because a cup has only 2.1 g of protein and 1 g of fiber, tomato juice works best as a side, not a meal. Next to eggs, yogurt or a bowl of beans, it adds volume and savory flavor for very few calories. On its own, it is closer to a drink than a snack.
It also makes a sensible swap when you want something with taste that is not sweet. At 17 calories per 100 g it sits well below orange juice, and the sugar is lower too. If sodium is on your radar, buy the no salt added carton and season the rest of the plate as usual.
Logging it is quick: BodyPal can log tomato juice from a photo, and you can pick the cup, the 6 fl oz can or the no salt added option so the sodium number matches what is actually in your glass.
How does tomato juice compare?
Here is how tomato juice stacks up against lime, coconut and orange juice, per 100 g and per usual serving.
Verdict: For the fewest calories, tomato juice at 17 per 100 g edges out coconut juice at 18 and beats orange juice at 49, which has about 2.9 times as much energy. If you watch sodium, orange juice at 2 mg or coconut juice at 26 mg per 100 g is the cleaner pick over salted tomato juice at 253 mg.
