The Calorie Count Explained
According to the USDA and various nutrition platforms, a single large, raw tomato typically contains about 33 calories. Therefore, a serving consisting of two large tomatoes amounts to roughly 66 calories. This figure is an average for standard red, ripe tomatoes, and the number can fluctuate based on the specific variety, its moisture content, and its precise weight. For instance, two large, green raw tomatoes may contain slightly more at 84 calories, while canned options can be lower.
Tomatoes' low-calorie density is largely due to their high water content, which is approximately 95%. The remaining mass is primarily composed of carbohydrates, fiber, and trace amounts of protein. This composition makes tomatoes a satisfying food choice that contributes to a feeling of fullness, which is helpful for managing weight. The macronutrient distribution for two large tomatoes is typically around 75% carbohydrates, 9% fat, and 17% protein.
How Size and Variety Affect Tomato Calories
Tomato calories vary depending on their size and variety. This is an important consideration when preparing meals, as the calorie content of a handful of cherry tomatoes is vastly different from one large beefsteak. A general breakdown shows the variation in calorie counts:
- Cherry Tomato: ~3 calories each
- Small Tomato: ~16 calories each
- Medium Tomato: ~22 calories each
- Plum or Roma Tomato: ~11 calories each
- Large Tomato: ~33 calories each
Different varieties can also have unique nutritional profiles. For example, red tomatoes are high in lycopene, but darker-hued varieties, like black and purple tomatoes, often pack a more concentrated nutritional punch.
Beyond Calories: A Nutritional Powerhouse
Beyond being a low-calorie food, tomatoes are packed with essential nutrients and beneficial compounds that support overall health. They are a significant dietary source of the antioxidant lycopene, which gives them their vibrant red color and is linked to numerous health benefits, including a reduced risk of heart disease and certain cancers. Other key nutrients include:
- Vitamin C: An essential nutrient and powerful antioxidant that boosts the immune system and promotes healthy skin.
- Potassium: An important mineral for regulating blood pressure and supporting heart health.
- Folate (Vitamin B9): Crucial for normal tissue growth and cell function, particularly for pregnant women.
- Vitamin K: Necessary for blood clotting and contributes to bone health.
- Beta-carotene: An antioxidant that gives some varieties a yellow or orange hue and is converted into vitamin A by the body.
Raw vs. Cooked Tomatoes
The method of preparation can significantly influence the nutritional profile of tomatoes. While raw tomatoes are an excellent source of heat-sensitive vitamin C, cooking tomatoes actually increases the bioavailability of lycopene, making it easier for your body to absorb. The heat breaks down the cell walls, releasing the powerful antioxidant. In fact, processed tomato products like tomato paste and sauces often have the richest concentration of lycopene. To maximize absorption of this fat-soluble compound, it is recommended to pair cooked tomatoes with a healthy fat, such as olive oil. For the full spectrum of benefits, incorporating both raw and cooked tomatoes into your diet is the best strategy.
Nutritional Comparison: Tomatoes vs. Other Produce
To put the calorie and nutrient content of tomatoes into perspective, here is a comparison with a few other common fruits and vegetables.
| Food Item | Calories (Approx.) | Water Content | Notable Nutrients |
|---|---|---|---|
| 1 Large Tomato | 33 kcal | ~95% | Lycopene, Vitamin C, Potassium |
| 1 Medium Banana | 105 kcal | ~75% | Potassium, Vitamin B6, Vitamin C |
| 1 Cup Chopped Tomatoes | 32 kcal | ~94% | Lycopene, Vitamin C, Potassium |
| 100g Broccoli | 34 kcal | ~89% | Vitamin K, Vitamin C, Folate |
Maximizing the Health Benefits of Tomatoes
To get the most out of your tomatoes, consider these tips:
- Choose the Right Variety: While all tomatoes are healthy, darker varieties (purple, brown, black) and deep red varieties often have a higher concentration of beneficial compounds.
- Cook for Lycopene: For maximum lycopene absorption, consume cooked tomato products like sauces, soups, or stews, and always add a little healthy fat to enhance absorption.
- Enjoy Both Raw and Cooked: For a balanced intake of nutrients, include raw tomatoes in salads to benefit from Vitamin C and cooked versions for higher lycopene levels.
- Buy in Season: Locally grown, in-season tomatoes that ripened on the vine tend to have superior flavor and nutritional value.
