Calorie Breakdown by Serving Size
To understand the caloric content of tomato puree, it is important to look at standard serving sizes, as the term '1 tomato puree' can be ambiguous. For instance, a small amount for seasoning will have significantly fewer calories than a full cup used as a sauce base.
- One Tablespoon (approx. 15g): This common serving size for adding flavor to sauces, soups, and stews contains around 6 calories and is virtually fat-free.
- One Cup (approx. 250g): A full cup of canned tomato puree without salt added contains approximately 95 calories. This amount provides a substantial boost of nutrients for a relatively low caloric investment.
- One Can: The calorie count for an entire can will depend on its size. For example, a 1-pound can contains about 172 calories, while a larger 820g can has around 312 calories.
Factors Influencing Calorie Count
While the base product of pureed tomatoes is naturally low in calories, the final count can change with preparation and additives. Store-bought purees sometimes have added salt, sugars, or preservatives, although this is less common than in tomato sauces. Homemade puree can also vary depending on the ripeness of the tomatoes and whether any oil is used in the cooking process. Homemade purees might also retain more fiber if the skin and seeds aren't completely removed.
The Nutritional Value Beyond Calories
Beyond its low-calorie nature, tomato puree is a nutritional powerhouse. It is a dense source of vitamins and minerals, many of which are more bioavailable after cooking.
Key Nutrients in Tomato Puree
Here is a list of some of the key nutrients found in a typical cup of plain tomato puree:
- Potassium: An essential mineral important for blood pressure regulation and heart health.
- Vitamin C: A powerful antioxidant that supports immune function.
- Vitamin K: Important for blood clotting and bone health.
- Dietary Fiber: Promotes healthy digestion and helps with satiety.
- Lycopene: The red pigment in tomatoes is a potent antioxidant. Cooking tomatoes, and particularly concentrating them into a puree, increases the bioavailability of lycopene, meaning your body can absorb more of it. For maximum absorption, consuming it with a small amount of healthy fat, like olive oil, is recommended.
Comparison: Puree, Paste, and Sauce
It is common to confuse tomato puree with other similar products. The primary difference lies in the consistency and concentration of the tomato solids, which in turn affects the calorie and nutrient density per serving.
Tomato Product Comparison
| Feature | Tomato Puree | Tomato Paste | Tomato Sauce |
|---|---|---|---|
| Consistency | Thicker than sauce, thinner than paste | Very thick and concentrated | Thinner than puree, typically seasoned |
| Calorie Density | Low to moderate. Approx. 95 kcal per cup | High. Approx. 82 kcal per 100g, very concentrated | Low. Approx. 24 kcal per 100g |
| Lycopene Content | High, especially when cooked | Highest due to concentration | Lower than puree or paste, but still beneficial |
| Flavor Profile | Rich and unseasoned, allowing for recipe customization | Intense, deep, and concentrated tomato flavor | Mild, often with added seasonings |
| Water Content | Medium, around 8-12% solids | Low, around 28-38% solids | High, more watery than puree |
Integrating Tomato Puree into a Healthy Diet
Given its low-calorie count and rich nutrient profile, tomato puree is an excellent ingredient for healthy cooking. It can be used as a base for low-calorie soups, stews, and sauces. For those managing weight, using puree instead of heavier cream-based sauces can significantly reduce the calorie load of a meal while enhancing flavor. The high lycopene content is especially beneficial for cardiovascular health and may help lower cholesterol. For optimal nutrient absorption, remember to pair it with a healthy fat.

Conclusion
In summary, the calorie content of tomato puree is remarkably low, with a standard tablespoon containing only about 6 calories. This makes it an ideal ingredient for adding rich, concentrated tomato flavor without excessive calories. The total calorie count increases with the volume used, so it's always wise to check the serving size. Beyond its low-calorie appeal, tomato puree is a nutritional powerhouse, packed with antioxidants, vitamins, and minerals that offer significant health benefits, especially when cooked. Whether homemade or canned, it remains a healthy and versatile staple for any kitchen.
