A cup of cherry tomatoes delivers just 27 calories, almost entirely from water and a modest 5.8 grams of carbohydrates, of which about 3.9 grams are natural sugars. The protein and fat are negligible at 1.3 and 0.3 grams respectively. What makes them noteworthy is the vitamin C content, 13.7 milligrams per cup, which covers about 17 percent of the daily reference, alongside their very low fat profile of 0.2 grams per 100 grams.

A normal portion is a full cup, eaten raw as a snack or tossed into a salad, and it works well as a light, hydrating bite between meals. Because they are so low in calories and protein, pair them with something more substantial like cheese, hummus, or eggs to make a satisfying mini-meal. They fill a bowl quickly without adding much bulk to a day's totals, so treat them as a flavor accent rather than a base for hunger.
