How many calories in a 15 oz can of diced Tomatoes?

Quick Answer

There are approximately 30 calories in a 15 oz can of diced tomatoes. The exact calorie count can vary slightly depending on the brand and any additional ingredients, but most 15 oz cans contain around 30 calories.

Calorie Count of Common Brands

Here is the calorie count for some common brands of 15 oz diced tomatoes:

Brand Calories per 15 oz
Hunt’s 30
Del Monte 30
Great Value (Walmart) 30
Kirkland (Costco) 30
Muir Glen Organic 35

As you can see, most major brands of diced tomatoes contain right around 30 calories per 15 oz can. The Muir Glen organic brand is slightly higher at 35 calories. This minor difference is likely due to the absence of preservatives.

Serving Size

The standard 15 oz can of diced tomatoes contains about 4 half-cup servings.

So if you were to consume the entire can, you would be eating approximately 4 servings of 30 calories each, totaling 120 calories.

However, most recipes that call for a 15 oz can of diced tomatoes will split it into about 4 servings. This means each serving would contain around 30 calories.

Factors Affecting Calorie Count

There are a few factors that can impact the calorie content in canned diced tomatoes:

Added Ingredients

Some diced tomato products have extra ingredients added, such as onions, garlic, basil, or olive oil. These added ingredients will increase the calorie count slightly. Read labels carefully to know exactly what is included.

Draining vs Undrained

Canned diced tomatoes are available in both “drained” and “undrained” options. Undrained means the tomatoes still have all the tomato juice. Draining the tomatoes removes some of the liquid and therefore decreases the calories slightly.

Fat Content

Tomatoes have very little fat, but brands with added oil will have slightly more fat and calories. For example, an oil-packed sun-dried tomato product would be higher in calories than a basic diced tomato.

Organic vs Conventional

Organic tomato products may be slightly higher in calories if they do not contain preservatives. The antioxidants in organic tomatoes may also contribute a few extra calories.

Sugar Content

While tomatoes themselves have little sugar, some companies add sugar or flavorings to diced tomatoes. Added sugar will increase calorie content.

Serving Size Consumed

As mentioned earlier, consuming the whole can at once will increase your calorie intake versus just eating a portion. Pay attention to suggested serving sizes on the label.

Tomato Nutrition Facts

Here is the nutrition breakdown for a standard half-cup serving of diced tomatoes:

Health Benefits of Tomatoes

Along with being low in calories, tomatoes offer many benefits:

High Antioxidant Content

Tomatoes contain the antioxidants lycopene and beta carotene which help fight free radicals and inflammation in the body. These antioxidants may lower risk of heart disease and cancer.

Vitamin & Mineral Content

Tomatoes provide vitamin C, potassium, folate and vitamin K. Vitamin C boosts immunity while potassium supports heart health and muscle function.

Fiber Content

The fiber in tomatoes helps control blood sugar and cholesterol. It also promotes digestive regularity and gut health.

Anti-Cancer Properties

Studies show that tomatoes may help fight several types of cancer, including prostate, lung and stomach cancer. The antioxidant lycopene is thought to be responsible for these anti-cancer benefits.

Heart Health

Tomatoes support heart health thanks to their combination of vitamin C, potassium, folate and various antioxidants. Together these nutrients help reduce heart disease risk.

Eye Health

The vitamins A and C in tomatoes support eye health and help prevent macular degeneration and cataracts.

Tips for Storing Canned Tomatoes

To retain the freshness and nutritional content of your canned diced tomatoes:

– Store unopened cans in a cool, dry place like your pantry. Avoid storage in hot garages or basements.

– Once opened, transfer tomatoes to an airtight container and refrigerate. Use within 4-5 days for best quality.

– Look for BPA-free cans to avoid chemical linings when possible.

– Rinse tomatoes before use to remove excess sodium.

– Buy no salt added or low sodium tomato options when available.

– Opt for tomatoes canned in juice rather than puree for a fresher texture.

– Look for tomatoes packed in glass jars rather than cans to avoid metal exposure.

Diced vs. Crushed vs. Whole Tomatoes

Canned tomatoes come in a few different forms:

Diced Tomatoes

Diced tomatoes are cut into small, uniform pieces. They maintain some shape and texture. Use them in soups, salads, curries, casseroles and more.

Crushed Tomatoes

Crushed tomatoes have been processed and crushed to remove most of the tomato shape. They have a thicker, sauce-like consistency. Use for pizza sauce, pasta sauce, and simmered dishes.

Whole Tomatoes

Whole tomatoes maintain the original shape and just have the cores removed. They keep a nice appearance and texture. Use them for chilis, stews, sautéed dishes, or garnishes.

Tomato Puree

Tomato puree has been cooked and strained to a smooth, thick liquid. It works well for recipes where you want a smooth sauce without chunks. Use in soups, dips, gravies, and baked goods.

Tomato Sauce & Paste

Tomato sauce and paste have the most moisture removed to create a thick, concentrated product. They are used more for enhancing flavor than as the main tomato component.

So in summary, diced tomatoes offer pieces that maintain shape and texture. Choose diced, crushed, or whole depending on your desired consistency.

Benefits of Canned Tomatoes

– Low cost and easily accessible year-round

– Saves prep time with no chopping required

– Provides consistent flavor and texture

– Nutrients are preserved at peak ripeness through canning process

Benefits of Homemade Diced Tomatoes

– Avoid preservatives or BPA from cans

– Can customize diced sizes and shape

– Adjust salt, seasonings, or ingredients to taste

How to Make Homemade Diced Tomatoes

If you have an abundance of fresh tomatoes, it’s worth dicing and freezing a batch:

Ingredients:
– Tomatoes
– Lemon juice (optional)
– Salt (optional)
– Olive oil (optional)

Steps:
1. Wash tomatoes and remove cores and stems. Cut in half crosswise.

2. Scoop out and discard the seeds. This reduces liquid in finished product.

3. Place tomato halves flat side down on cutting board. Slice into 1/4 to 1/2 inch wide strips.

4. Rotate tomato 90 degrees and slice again to create neat diced pieces.

5. Transfer diced tomatoes to freezer bag or container. If freezing, leave 1 inch headspace for expansion.

6. Optionally, sprinkle with salt, olive oil, and lemon juice before freezing. This boosts flavor.

7. Remove as much air from freezer bag as possible and seal. Freeze for up to 6 months.

Be sure to label bags with contents and date before freezing. Thaw smaller amounts overnight in fridge before using.

Frequently Asked Questions

Here are answers to some common questions about canned diced tomatoes:

Why are canned tomatoes picked at peak ripeness?

Canned tomatoes are picked when fully ripe and then processed within hours to preserve maximum flavor, color, and nutrition. On the vine, ripening continues after picking.

Are canned tomatoes nutritious?

Yes, canned tomatoes retain a majority of their vitamin A, vitamin C, potassium and antioxidant lycopene content through the canning process due to quick heat application. Choose low sodium options.

Are canned tomatoes already cooked?

Canned tomatoes are lightly cooked during the canning process to stop ripening and deactivate enzymes. This light cooking also softens skins and brings out flavor.

Can you substitute fresh tomatoes for canned?

In cooked dishes, yes. Use an equivalent amount and adjust seasonings as needed. Cook fresh tomatoes longer to break down texture. Fresh won’t work for purees.

How long do opened canned tomatoes last?

Once opened, canned tomatoes will last 4-5 days in the refrigerator. Transfer contents to an airtight container and use within this timeframe for best flavor and quality.

Conclusion

A 15 oz can of diced tomatoes contains around 30 calories and provides beneficial nutrients like vitamin C, lycopene, potassium and vitamin A. Look for varieties without added salt or sugar. Canned diced tomatoes work well in soups, casseroles, curries, chili, and more. While fresh tomatoes taste amazing, canned tomatoes provide year-round convenience and value. Use within 4-5 days of opening and store remaining cans in a cool, dry pantry.
