The Truth About Tomato Protein
While often mistaken for a vegetable, the tomato is a fruit that is celebrated for its versatility in cooking and its rich content of vitamins and antioxidants. However, when it comes to protein, it's not a star player. A medium-sized, raw tomato (approx. 123g) contains only about 1 gram of protein, which means two of these tomatoes will give you roughly 2 grams. It is important to note that the protein content can fluctuate slightly depending on the tomato's size and variety, but the overall contribution to your daily protein intake remains minimal. Those seeking to meet their protein goals should look to other food sources, using tomatoes as a complement rather than a foundation.
The Impact of Cooking on Tomato Nutrition
Cooking can affect the nutritional profile of food, and tomatoes are no exception. For protein, the change is generally not significant enough to make a large difference in total intake. However, cooking does have a powerful effect on other compounds within the tomato, particularly its antioxidants. For instance, the bioavailability of lycopene—a potent antioxidant linked to heart health and a reduced risk of certain cancers—is significantly increased when tomatoes are cooked. Therefore, adding cooked tomatoes or tomato paste to sauces and soups can actually be more beneficial for your health in certain ways, even if the protein content is not a major factor.
Practical ways to enjoy cooked tomatoes with more protein:
- Tomato and Lentil Soup: Add cooked lentils to a tomato-based soup for a substantial protein boost.
- Shakshuka: Poach eggs in a simmering sauce of tomatoes, onions, and spices for a complete, protein-rich meal.
- Pasta with Meat Sauce: Combining a tomato sauce with ground beef, turkey, or a plant-based alternative dramatically increases the protein.
- Chickpea and Tomato Salad: Toss cooked chickpeas with raw tomatoes, cucumber, and a light dressing for a fresh, protein-packed side dish.
Comparison Table: Tomato Protein vs. Other Foods
To put the protein content of two tomatoes into perspective, let's compare it with other common foods. This table highlights that tomatoes are not the go-to choice for muscle building or satisfying a high-protein diet, but they are a valuable source of other nutrients.
| Food Item | Approximate Protein Content | Comparison Notes |
|---|---|---|
| 2 Medium Raw Tomatoes | ~2 grams | A very low amount, primarily carbohydrate and water-based. |
| 1 Large Egg | ~6 grams | A single egg provides three times the protein of two medium tomatoes. |
| 1/2 Cup Cooked Lentils | ~9 grams | Lentils are an excellent plant-based protein source. |
| 100g Chicken Breast | ~31 grams | A significant source of lean animal protein. |
| 1/2 Cup Cooked Quinoa | ~4 grams | Quinoa is a complete protein and a better grain-based source than tomatoes. |
Beyond Protein: The Nutritional Power of Tomatoes
It's a mistake to focus only on protein when evaluating tomatoes. Their true strength lies in their wealth of other essential nutrients and health benefits. They are particularly known for:
- Vitamins: An excellent source of Vitamin C, which is crucial for immune function, and Vitamin K, vital for blood clotting.
- Potassium: Contains a good amount of potassium, which is important for maintaining healthy blood pressure.
- Fiber: A moderate source of dietary fiber, which aids in digestion and promotes a feeling of fullness.
- Lycopene: As a powerful antioxidant, lycopene protects cells from damage and has been linked to reducing the risk of heart disease and certain cancers, such as prostate cancer. The redder the tomato, the higher the lycopene content tends to be.
- Hydration: With about 95% water content, tomatoes help keep you hydrated.
Conclusion
In summary, two tomatoes offer a minimal amount of protein, typically around 2 grams. For those focused on increasing protein intake, tomatoes are not the most efficient choice. Instead, they should be appreciated for their rich supply of vitamins C and K, potassium, fiber, and especially the powerful antioxidant lycopene. To create a well-rounded, protein-rich meal, it is best to combine tomatoes with other high-protein ingredients like legumes, eggs, or lean meat. This allows you to reap the numerous health benefits of tomatoes while still achieving your protein goals.

Frequently Asked Questions
- How many protein is in 2 tomatoes? Two average medium-sized, raw tomatoes contain approximately 2 grams of protein.
- Are tomatoes a good source of protein? No, tomatoes are not considered a good source of protein due to their very low protein density. They are primarily a source of carbohydrates, vitamins, and water.
- What are the main nutrients in tomatoes? Tomatoes are rich in Vitamin C, Vitamin K, potassium, and are a significant source of the antioxidant lycopene.
- How can I add more protein to a tomato-based dish? To increase the protein in a dish with tomatoes, consider adding ingredients like chicken, chickpeas, lentils, tofu, or cheese.
- Does cooking tomatoes change their nutritional value? Yes, cooking tomatoes can increase the bioavailability of certain nutrients, most notably the antioxidant lycopene, while the effect on protein content is negligible.
- Do all types of tomatoes have the same protein content? The protein content can vary slightly depending on the variety and size of the tomato, but all tomatoes are generally low in protein.
- What is lycopene and why is it important? Lycopene is a powerful antioxidant found in red tomatoes that has been linked to a reduced risk of heart disease and certain cancers, such as prostate cancer.
- Are green tomatoes lower in protein than red tomatoes? While the nutritional profile differs slightly (green tomatoes have no lycopene), the overall protein content remains similarly low in both green and ripe red tomatoes.
