Calorie Count: How Many Calories are in 100 g of Vine Tomatoes?
An average 100-gram serving of raw, ripe vine tomatoes contains around 18 to 20 calories. This low-calorie density is primarily due to their high water content, which makes up about 95% of their total weight. The remaining content consists mainly of carbohydrates, with a small amount of fiber, protein, and fat.
Breaking down the calorie calculation reveals where this energy comes from. Calories are derived from the macronutrients present in the food. For a typical 100-gram serving of tomatoes, the approximate macronutrient breakdown is:
- Carbohydrates: ~3.9g (at 4 calories per gram)
- Protein: ~0.9g (at 4 calories per gram)
- Fat: ~0.2g (at 9 calories per gram)
Using these values, the total calorie count is approximately (3.9 4) + (0.9 4) + (0.2 * 9) = 15.6 + 3.6 + 1.8 = 21 calories. This confirms the range found in various nutritional databases.
The Complete Nutritional Breakdown of Vine Tomatoes
Beyond their low-calorie nature, vine tomatoes offer a robust nutritional profile. They are an excellent source of several key vitamins and minerals that are vital for overall health.
Vitamins and Minerals in 100g of Tomatoes
- Vitamin C: A powerful antioxidant that supports the immune system and skin health. A 100g serving can provide a significant portion of your daily needs.
- Potassium: An essential mineral important for blood pressure control and heart health.
- Vitamin K1: Crucial for blood clotting and bone health.
- Folate (B9): Important for cell function and tissue growth, especially for pregnant women.
- Vitamin A: Important for vision, immune function, and cell specialization.
The Health Benefits Beyond the Calorie Count
Eating vine tomatoes offers numerous health benefits, primarily driven by their high content of antioxidants, especially lycopene. Lycopene is the red pigment that gives tomatoes their vibrant color and has been extensively studied for its protective properties.
Some of the key health benefits include:
- Heart Health: Lycopene can help lower levels of LDL ('bad') cholesterol and blood pressure, reducing the risk of heart disease.
- Cancer Prevention: Studies have linked high intake of lycopene to a reduced risk of certain cancers, such as prostate, lung, and stomach cancers.
- Skin Protection: The antioxidants in tomatoes, including lycopene, can offer some protection against sun damage.
- Immune Support: The rich vitamin C content helps strengthen the immune system, protecting against infections.
Comparison: Vine-Ripened vs. Regular Tomatoes
There is a common perception that vine-ripened tomatoes are superior in taste and nutrition. Scientific studies provide some interesting insights into the differences between tomatoes ripened on the vine versus those picked green and ripened off the vine.
| Feature | Vine-Ripened Tomatoes | Off-the-Vine (Counter-Ripened) Tomatoes |
|---|---|---|
| Lycopene Content | Higher levels of lycopene and beta-carotene can be achieved when ripened on the vine, although counter-ripening can also yield similar levels over time. | Lycopene content increases during ripening, but may not reach the same peak levels as vine-ripened tomatoes. |
| Sugar & Flavor | Significantly higher levels of sugars (fructose, glucose) and flavor compounds (glutamate, aspartate) are achieved during vine-ripening, contributing to a sweeter, more complex taste. | Lower levels of key sugars and flavor compounds, resulting in a less intense flavor profile. |
| Firmness | Retain a firmer texture for longer compared to those ripened off the vine. | Tend to be softer and less firm due to the altered ripening process. |
| Nutrient Absorption | The nutritional content is locked in while still on the vine, maximizing flavor and antioxidants. | Nutrients are not absorbed from the vine, leading to less potent flavor and some nutritional variation. |
Cooking vs. Raw: Maximizing the Benefits
How you consume tomatoes can affect the bioavailability of their nutrients. Eating them raw is great for preserving vitamin C, which is heat-sensitive. However, cooking tomatoes can actually increase the amount of lycopene your body can absorb. The heat breaks down the cell walls, making the lycopene more accessible. Adding a healthy fat, like olive oil, further enhances lycopene absorption. A simple caprese salad offers a raw option, while a homemade marinara sauce provides a cooked alternative.

Conclusion
In summary, 100 grams of vine tomatoes contain a low number of calories, typically ranging from 18 to 20 kcal, and are primarily composed of water. Despite their low energy density, they are a highly nutritious food, providing a wealth of vitamins, minerals, and the potent antioxidant lycopene. The method of ripening can influence their final flavor and nutrient content, with vine-ripening leading to a potentially richer flavor profile. Whether enjoyed raw or cooked, vine tomatoes are a flavorful and healthy addition to any diet, offering significant benefits for heart health, immunity, and overall well-being. Their versatility makes them a simple and effective way to boost your daily nutrient intake.
