No, tomatoes are low in protein—around 1 g per medium tomato; choose higher-protein sides if you need more.
Tomatoes bring color, acidity, and freshness to plates, but they don’t deliver much protein. A medium red tomato lands near 1 gram of protein, and even a full cup barely reaches 1.5 grams. That means tomatoes play a flavor and micronutrient role rather than a protein role. If you’re shaping meals around protein targets, think of tomatoes as a topper or base that pairs with beans, tofu, eggs, fish, meat, cheese, or protein-rich grains.
Tomato Protein At A Glance
Here’s a quick view of how much protein appears across common tomato types and products. Values come from standard nutrient databases and label baselines. Portion sizes reflect what people usually serve.
| Tomato Or Product | Common Serving | Protein (g) |
|---|---|---|
| Raw Tomato (Medium) | 123 g (1 medium) | ~1.0 |
| Raw Tomato (100 g) | 100 g | 0.9 |
| Cherry Tomatoes | 85 g (handful) | 0.7 |
| Grape/Plum Tomatoes | 100 g | 0.9 |
| Canned Diced Tomatoes | 121 g (1/2 cup) | 0.6 |
| Tomato Sauce (Canned) | 125 g (1/2 cup) | 1.6 |
| Tomato Paste | 66 g (1/4 cup) | 2.9 |
| Sun-Dried Tomatoes | 28 g (1 oz) | 4.0 |
Tomato Protein: What The Numbers Say
Short answer: they’re not. Raw tomatoes hold a lot of water—close to 95%. When water dominates, protein density stays low. Per 100 grams, raw tomatoes sit near 0.9 gram of protein. A typical medium tomato gives about 1 gram. Even a full cup of chopped tomato stays around 1.5 grams. Those totals barely move the needle for daily protein goals. Tomato protein stays low; the math makes that clear.
Tomato products change the picture a bit. Paste concentrates solids, so protein per spoon climbs. Sun-dried tomatoes remove most of the water, so protein per weight jumps even higher. That said, the serving you actually eat tends to be small—think a spoon of paste in sauce or a few strips of sun-dried tomato in a salad—so the protein per plate still lands low.
Why The Protein Looks Low
Plants with high water content push down protein density. Lettuce, cucumber, and tomato all fit this pattern. Beans, lentils, soy foods, meat, dairy, and eggs look strong for protein because they carry far less water—or they’re concentrated during processing.
Is Tomato A Good Protein Source For Meals?
Tomato fits beautifully next to protein sources, but it doesn’t stand in for them. The win is in pairing. Add chopped tomato to a chickpea salad, spoon a bright salsa over grilled fish, slide thick tomato slices into a turkey sandwich, or simmer crushed tomatoes with lentils for a hearty stew. You get fiber, potassium, vitamin C, and lycopene from the tomato, while the partner food brings the heavy protein lift.
How Much Protein Do You Need?
Most adults can plan around 0.8 g of protein per kilogram of body weight each day. A 70-kg person lands near 56 grams. Many active people aim higher at meals by spacing protein across the day, but the base target gives a clear yardstick. You can review the current RDA language through the protein recommended dietary allowance.
Tomato Nutrition Beyond Protein
Even with low protein, tomatoes still earn a seat at the table. They add vitamin C, potassium, folate, and pigments such as lycopene. Those nutrients help taste, color, and balance in dishes. A simple plate of eggs and toast feels livelier with sliced tomato. A grain bowl with lentils perks up when you fold in blistered cherry tomatoes and herbs. You get a better eating experience and a steady mix of macros and micros.
Cooking can boost flavor and release lycopene from the cell walls. A slow simmer of crushed tomatoes builds a rich base for beans, tofu, or meat. Roasting cherry tomatoes concentrates sweetness and adds a jammy edge that pairs well with salty cheese or grilled chicken.
Ways To Raise Protein With Tomatoes
Here are easy, tasty pairings that keep tomato in the mix while pushing protein up:
- Eggs + Tomato: Scramble eggs with diced tomatoes and herbs; finish with a little cheese.
- Tuna Or Salmon + Tomato: Mix flaked fish with chopped tomato and onion for a speedy salad.
- Chicken + Tomato: Roast thighs with canned tomatoes, garlic, and olives; spoon the pan juices over rice.
- Tofu + Tomato: Crisp tofu cubes, then braise briefly in a tomato-ginger sauce.
- Beans/Lentils + Tomato: Stir tomatoes into chili or dal for depth and a hit of acid.
- Whole Grains + Tomato: Fold cherry tomatoes into quinoa or farro with feta and basil.
- Greek Yogurt + Tomato: Swirl tomato chutney or roasted cherry tomatoes into yogurt for a savory dip.
Protein In Tomatoes Versus Other Foods
This table stacks tomato against common choices in the kitchen. Use it to plan plates that meet your targets.
| Food | Typical Serving | Protein (g) |
|---|---|---|
| Raw Tomato | 123 g (1 medium) | ~1 |
| Broccoli, Cooked | 156 g (1 cup) | 4.0 |
| Potato, Baked | 173 g (1 medium) | 4.3 |
| Cooked Lentils | 198 g (1 cup) | 18 |
| Cooked Chickpeas | 164 g (1 cup) | 14.5 |
| Firm Tofu | 85 g (3 oz) | 8–10 |
| Chicken Breast, Cooked | 85 g (3 oz) | 26 |
| Eggs | 2 large | 12 |
| Greek Yogurt, Plain | 170 g (3/4 cup) | 15–17 |
Smart Use Of Tomato Products
Tomato paste and sun-dried tomatoes look higher on paper because water drops out. Per 100 grams, paste lands near 4–5 grams of protein, and sun-dried tomatoes can top 14 grams. The catch is serving size. A quarter cup of paste holds under 3 grams; an ounce of sun-dried strips sits near 4 grams. Handy, but still a sidekick. You can browse the official database entries through USDA FoodData Central to confirm serving sizes and nutrient lines.
Also watch sodium. Many canned tomato products and jarred sun-dried tomatoes use salt for taste and safety. Pick “no-salt-added” when it fits, or balance the meal by salting the dish, not the product. Oil-packed sun-dried tomatoes bring extra calories from oil; dry-pack keeps it leaner.
Are Tomatoes High In Protein? Daily Needs And Gaps
Let’s place those grams against a daily target. If you need 56 grams per day, a medium tomato gives about 1 gram—only 2% of that target. Even a large salad with two cups of chopped tomato reaches just 3 grams. You still need strong anchors at meals to land on your number.
Protein Math: Turning Targets Into Plates
Here’s a simple way to hit your number while keeping tomatoes in the picture. Start with your daily target, split it across three meals, and backfill with snacks. A 56-gram target becomes three meals at 18–20 grams plus a small snack. Now plug tomato into each plate:
- Breakfast: Two eggs (12 g), toast with cottage cheese (6–8 g), sliced tomato on top. Add a few olives or greens for flavor.
- Lunch: Lentil-tomato soup (15–18 g from the lentils) with a tuna salad half-sandwich (10–15 g). Add a side of cherry tomatoes.
- Dinner: Grilled chicken (25–30 g) over a warm farro-tomato salad. Finish with a yogurt cup if you’re short.
- Snack: Whole-grain crackers with a tomato-chickpea dip (5–7 g).
This lineup clears the target while letting tomato show up in every course. Are tomatoes high in protein? No, but they round out plates with acid, color, and freshness while your protein anchors do the heavy lifting.
Serving Sizes And Simple Swaps
When you see database entries, you’ll notice lots of serving sizes: slices, cups, ounces, grams. Use these quick guides in your kitchen:
- 1 medium tomato: near 120–130 g; plan on ~1 g protein.
- 1 cup chopped tomato: near 180 g; plan on ~1.5 g protein.
- 1 tbsp tomato paste: near 16 g; plan on ~0.7 g protein.
- 1 oz sun-dried tomato: near 28 g; plan on ~4 g protein.
Need a bit more protein without changing the dish? Swap a slice of regular bread for high-protein bread, spoon Greek yogurt in place of sour cream, choose edamame over peas, or fold in an extra scoop of beans. Tomato plays well with all of these.
Shopping, Storage, And Prep Tips
Pick tomatoes that feel heavy for their size and smell fragrant near the stem. Keep whole tomatoes at room temperature until ripe, then chill to slow softening. Bring them back to room temp before slicing for the best flavor. For paste, close the open can with a lid or transfer to a small jar and refrigerate; freeze spoonfuls in an ice-cube tray for later. For sun-dried tomatoes, check whether the jar is oil-packed or dry-pack; store opened jars in the fridge and keep dry-pack in a sealed bag to protect from moisture.
Quick prep moves make tomato pairings painless. Pre-roast a tray of cherry tomatoes to keep in the fridge, whisk a fast vinaigrette, and cook a pot of lentils or quinoa. With those on hand, you can build protein-smart plates in minutes.
Method Notes: Where The Numbers Come From
The protein values in the tables come from widely used nutrient datasets and label baselines. We pulled raw tomato, paste, and sun-dried tomato figures from sources built on USDA data, and we matched serving sizes to the way people eat. Menus above use those same baselines so you can plan without a calculator.
Takeaway On Tomato Protein
Tomatoes shine in taste, texture, and micronutrients. For protein needs, use them as a partner. Build meals around beans, lentils, tofu, fish, meat, eggs, or Greek yogurt, and let tomatoes bring freshness and color. Are tomatoes high in protein? No—and that’s fine. They do other jobs on the plate, and they do them well.
