What is 100g of Tomatoes in a Practical Sense?
When you're preparing a meal or portioning your food, visualizing 100 grams can be a challenge. In practical terms, 100g of tomatoes equates to roughly one medium-sized tomato, which is a convenient way to measure your intake. However, depending on the variety, the number of tomatoes can vary significantly. For example, a handful of smaller cherry tomatoes would add up to 100g, while a single, small-to-medium Italian or plum tomato could also be close to this weight. This makes it a flexible and easy portion size to include in a wide variety of recipes.
Size Equivalents for 100g
Here are some common tomato varieties and how they relate to a 100g portion:
- One medium common tomato: A single, average-sized tomato often weighs around 100 grams.
- Five to seven cherry tomatoes: Given that a single cherry tomato weighs approximately 17 grams, a handful will quickly reach the 100g mark.
- Two plum or Italian tomatoes: These are slightly smaller and more oval-shaped. A single plum tomato is about 62g, so two would make a generous 100g serving.
- A quarter of a large beefsteak tomato: Beefsteak tomatoes can be quite large, with some weighing up to 500g or more. Using a kitchen scale for these larger varieties is recommended to ensure accuracy.
Nutritional Breakdown for 100g of Tomatoes
Beyond their low-calorie count, 100g of raw tomatoes is a nutritional powerhouse. They are primarily composed of water (around 95%), which contributes to their hydrating properties. The remaining 5% is packed with essential nutrients, including carbohydrates, fiber, vitamins, and minerals. The specific figures can vary slightly between sources, but the general profile remains consistently healthy.
Key Nutrients in a 100g Serving
- Calories: Approximately 18 kcal.
- Water: Around 95g.
- Protein: About 0.9 grams.
- Carbohydrates: Roughly 3.9 grams, primarily composed of simple sugars and dietary fiber.
- Fiber: Approximately 1.2 grams.
- Vitamin C: A good source of this essential antioxidant, which supports immune function and skin health.
- Potassium: An important mineral for blood pressure regulation and heart health.
- Lycopene: A powerful antioxidant, particularly concentrated in the skin of red tomatoes. The concentration of lycopene is even higher in cooked or processed tomato products.
Comparison Table: 100g Fresh vs. Canned Tomatoes
While the nutritional profile of fresh tomatoes is excellent, processing can alter the content of certain compounds like lycopene. Here’s a quick comparison of the nutritional values per 100g:
| Nutrient | 100g Fresh Tomatoes | 100g Canned Tomatoes (packed in juice) |
|---|---|---|
| Calories | ~18 kcal | ~16 kcal |
| Carbohydrates | ~3.9 g | ~3.0 g |
| Fiber | ~1.2 g | ~1.0 g |
| Vitamin C | ~14 mg | ~14 mg |
| Lycopene | ~1-8 mg | ~10-14 mg |
As the table indicates, processed tomato products can offer an even higher concentration of lycopene, which is more readily absorbed by the body when cooked with a source of fat.
Health Benefits of a 100g Serving
Incorporating a small, 100g serving of tomatoes into your diet offers a range of health benefits, thanks to its high water content and dense nutrient profile. Here’s why this small portion is beneficial:
