Calculating the Calories in 400g of Roma Tomatoes
When considering the energy content of Roma tomatoes, it's helpful to start with the baseline value for 100g. Raw Roma tomatoes typically contain about 18 calories per 100 grams. To determine the total calories for a 400g portion, you simply multiply the per-100g value by four. This calculation reveals that 400g of raw Roma tomatoes contains approximately 72 calories. This remarkably low energy density is one of the main reasons they are a popular choice for those managing their weight or aiming for a nutrient-dense diet. This total can vary slightly depending on factors like ripeness and specific variety, but 72 calories serves as a reliable estimate.
Nutritional Profile of 400g Roma Tomatoes
Beyond their low-calorie count, Roma tomatoes offer an impressive array of nutrients. A 400g serving provides substantial amounts of vitamins and minerals crucial for overall health.
- Macronutrients: A 400g portion delivers roughly 16 grams of carbohydrates and 4 grams of protein, while remaining very low in fat at around 1 gram. A significant portion of the carbohydrates (approximately 5g) comes from dietary fiber, which aids digestion and promotes satiety.
- Vitamins: These tomatoes are an excellent source of Vitamin C, which supports immune function and skin health, and Vitamin A, vital for vision and cell growth. They also contain Vitamin K, important for blood clotting and bone health.
- Minerals: A 400g serving contains potassium, which is key for regulating blood pressure, along with smaller amounts of calcium and iron.
- Antioxidants: Roma tomatoes are particularly renowned for their high concentration of lycopene, a powerful antioxidant. Lycopene has been linked to numerous health benefits, including a reduced risk of certain cancers and heart disease. Interestingly, cooking tomatoes can increase the bioavailability of lycopene, making it easier for the body to absorb.
Raw vs. Cooked: How Preparation Affects Calories
The calorie count of Roma tomatoes can be altered during cooking, but it's not the tomato itself that changes significantly. Rather, it's the added ingredients. Cooking with oil, for example, will increase the final calorie total of your dish.
| Preparation Method | Key Characteristics | Calorie Impact per 400g (Approx.) |
|---|---|---|
| Raw | Uncooked, simple addition to salads or snacks. | ~72 calories |
| Roasted | Cooked with oil, herbs, and seasonings. Oil adds calories. | 150-200+ calories |
| Sauce | Simmered and reduced. Calorie count depends on added oil and other ingredients. | Variable, typically higher than raw |
| Salsa | Raw or lightly cooked with other ingredients like onions and peppers. Minimal added calories. | ~80-100 calories |
