Cherry Tomato Carbs: Exact Count Per Serving (2025 Data)

One cup (149g) of cherry tomatoes contains approximately 6 grams of total carbohydrates, with about 2 grams of fiber, resulting in 4 grams of net carbs. This makes them an excellent low-carb option for keto, diabetic, and weight management diets while providing essential vitamins and antioxidants.

Understanding Carbohydrate Content in Cherry Tomatoes

When tracking your daily carbohydrate intake, knowing the precise nutritional profile of foods like cherry tomatoes is essential. Based on the latest USDA FoodData Central database, cherry tomatoes offer a nutrient-dense package with minimal impact on your carb count.

Cherry tomatoes are not only delicious but also remarkably low in carbohydrates compared to many other fruits and vegetables. Their small size and sweet flavor might suggest higher sugar content, but the reality is quite different. Let's break down exactly what you're consuming when you enjoy these bite-sized treats.

Serving Size	Total Carbs	Dietary Fiber	Net Carbs	Natural Sugars
1 cherry tomato (5g)	0.2g	0.07g	0.13g	0.1g
1 cup (149g)	6g	2g	4g	3.9g
100g	3.9g	1.2g	2.7g	2.5g

This nutritional breakdown comes directly from the USDA's comprehensive food composition database, which is updated regularly with laboratory analysis of food items. The data reflects raw cherry tomatoes, as cooking methods can slightly alter carbohydrate availability.

Cherry Tomatoes vs. Other Tomato Varieties

If you're monitoring your carbohydrate intake, understanding how cherry tomatoes compare to other tomato varieties can help you make informed choices. While all tomatoes are relatively low in carbs, there are subtle differences worth noting:

Tomato Type	Carbs per 100g	Fiber per 100g	Net Carbs per 100g	Notable Characteristics
Cherry tomatoes	3.9g	1.2g	2.7g	Slightly sweeter, higher lycopene content
Grape tomatoes	4.2g	1.1g	3.1g	Denser, less water content
Roma tomatoes	3.9g	1.2g	2.7g	Lower moisture, firmer texture
Beefsteak tomatoes	3.9g	1.2g	2.7g	Higher water content, milder flavor

According to research published by the National Center for Biotechnology Information, the slight variations in carbohydrate content among tomato varieties primarily come from differences in water content and maturity at harvest rather than fundamental compositional differences.

Practical Applications for Different Dietary Needs

Understanding how cherry tomatoes fit into various dietary frameworks can help you maximize their nutritional benefits while staying within your carb limits.

For Keto and Low-Carb Dieters

With only 2.7g of net carbs per 100g, cherry tomatoes are keto-friendly in moderate portions. Most keto dieters aim for 20-50g of net carbs daily, meaning you could enjoy a full cup (149g) of cherry tomatoes while still having room for other vegetables. The fiber content also supports digestive health, which can be challenging on very low-carb diets.

For Diabetics and Blood Sugar Management

Cherry tomatoes have a low glycemic index (estimated at 15-20) and glycemic load of just 1 per cup, making them an excellent choice for blood sugar management. The American Diabetes Association includes tomatoes in their list of non-starchy vegetables that can be consumed freely by people with diabetes.

For Weight Management

At just 27 calories per 100g, cherry tomatoes provide volume and satisfaction with minimal caloric impact. Their high water content (95%) and fiber contribute to feelings of fullness, making them valuable for weight management strategies. Registered dietitians often recommend including cherry tomatoes in salads and snacks to increase meal volume without significantly increasing calorie or carb counts.

Maximizing Nutritional Benefits While Tracking Carbs

To get the most from cherry tomatoes while maintaining your carb goals, consider these practical tips:

• Pair with healthy fats: Consuming cherry tomatoes with olive oil or avocado enhances absorption of fat-soluble nutrients like lycopene and beta-carotene
• Watch portion sizes: A standard serving is about 1 cup (149g), which keeps net carbs around 4g
• Avoid sugary preparations: Roasting with sugar or using sweetened dressings can significantly increase carb content
• Choose organic when possible: Some studies suggest organic tomatoes may have higher antioxidant levels
