Comparing Caloric Content Across Tomato Varieties

Not all tomatoes are created equal. While the differences in calories are minor, the nutritional profiles can vary slightly depending on the tomato type and preparation method.

Tomato Variety (58g serving) Approx. Calories Macronutrient Breakdown (Carbs/Protein/Fat) Notable Nutrient Differences
