Calorie Breakdown: Fresh vs. Canned Chopped Tomatoes
When considering how many calories are in 100g of chopped tomatoes, the preparation method is a key factor. Fresh, raw tomatoes are the most straightforward option, with a standard 100g serving providing approximately 18 calories. However, canned chopped tomatoes can vary slightly in their nutritional profile depending on the added ingredients, such as salt or sugar, though many 'no salt added' varieties maintain a very similar low-calorie count.
Nutritional Facts for 100g of Raw Chopped Tomatoes
A 100g serving is relatively small and can be easily incorporated into many dishes without significantly adding to the total calorie count. Here is a typical nutritional breakdown for 100g of fresh, raw chopped tomatoes:

Fresh vs. Canned: What's the Difference?
While both fresh and canned tomatoes are nutritious, there are some subtle differences worth noting. Canned varieties are often picked and processed at peak ripeness, which can increase the bioavailability of certain nutrients, especially lycopene. However, the canning process can also lead to a slight reduction in some heat-sensitive vitamins, like Vitamin C. Another consideration for canned versions is the potential for added sodium, so it's always best to check the label and opt for 'no salt added' options if possible.

Health Benefits of Adding Chopped Tomatoes to Your Diet
Beyond their low-calorie nature, chopped tomatoes are a powerhouse of essential vitamins, minerals, and antioxidants that support overall health.
- Rich in Antioxidants: Tomatoes are the primary dietary source of lycopene, a powerful antioxidant that protects cells from damage. Research suggests that diets high in lycopene may help reduce the risk of certain cancers, including prostate and breast cancer.
- Heart Health: The potassium, vitamins, and flavonoids in tomatoes can help support heart health by lowering levels of 'bad' cholesterol (LDL) and blood pressure. The antioxidant properties also help ease inflammation, which is a risk factor for heart disease.
- Immune System Support: With high levels of Vitamin C and other antioxidants, tomatoes help fortify the body's natural defense system.
- Weight Management: Due to their high water and fiber content, tomatoes can increase feelings of fullness and aid in appetite control. This makes them an excellent low-calorie ingredient for those looking to lose or maintain weight.
- Improved Vision: The carotenoids lutein and zeaxanthin found in tomatoes can help protect the eyes from light-induced damage and reduce the risk of age-related macular degeneration (AMD).
Cooking with Chopped Tomatoes
Chopped tomatoes are incredibly versatile and can be used in a wide array of dishes. Here are a few ways to incorporate them into your meals:
- Sauces: The most classic use is for making delicious, low-calorie tomato sauces for pasta, pizza, or as a base for stews and curries.
- Salads: Freshly chopped tomatoes add a burst of flavor and texture to any salad. Combine them with cucumbers, red onion, and fresh herbs for a simple and healthy side dish.
- Salsas: A homemade salsa with fresh chopped tomatoes, cilantro, onion, and lime juice is a healthier alternative to store-bought versions that can contain high amounts of sugar and sodium.
- Soups: Start your meal with a warm, soothing bowl of tomato soup made from fresh or canned chopped tomatoes.
- Omelets and Scrambles: Add chopped tomatoes to your morning eggs for extra flavor and nutrients.
