Tomato Protein — Frequently Asked Questions
How much protein is in 100g of Tomato? 100g of Tomato contains 0.9 g of protein (USDA FoodData Central). This is a low-protein food.
How much protein in one Tomato? A typical tomato weighs about 123g and contains 1.1 g of protein. This is calculated as 123g ÷ 100 × 0.9 = 1.1 g.
How much protein is in 1 cup of Tomato? One US cup of tomato weighs approximately 225g (density: 950 kg/m³). That serving contains 2 g of protein — computed as 225g ÷ 100 × 0.9.
How many grams of Tomato do I need to eat to get 30 g of protein? To reach 30 g of protein from Tomato, you need approximately 3333g — calculated as (30 ÷ 0.9) × 100 = 3333g.
Is Tomato high in protein? Tomato is low in protein at 0.9 g per 100g. If you're targeting this nutrient, Tomato alone is unlikely to be sufficient.
What percentage of daily protein does 100g of Tomato provide? 100g of Tomato provides 0.9 g of protein, which is 1.8% of the reference daily intake (50 g/day for adults, based on a 2000-calorie diet). To reach 100% of your daily protein from Tomato alone, you would need ~5556g.
How efficient is Tomato as a source of protein per calorie? Tomato provides 5 g of protein per 100 kcal, making it good as a protein-per-calorie source. This is useful for calorie-restricted diets where macronutrient density matters.
What formula does this Tomato protein calculator use? The calculator uses protein = weight in grams / 100 x 0.9 g. For example, 100g of Tomato gives 0.9 g of protein. Volume entries are first converted to grams using the food density value, then the same per-100g formula is applied.
Is Tomato a good food for muscle building or high-protein goals? For muscle building or high-protein goals, Tomato is a modest contributor — with 0.9 g of protein per 100g. For best results, combine Tomato with other foods to hit your daily macro targets.
How reliable is the source data for Tomato? Tomato uses USDA FoodData Central reference as the nutrition source. Gram-based calculations use the per-100g source values, while cup and spoon estimates depend on the listed density and should be treated as practical serving estimates.
How to Calculate Tomato Protein
- Weigh raw. Place your tomato on a kitchen scale before cooking to get the most accurate starting weight.
- Enter weight into the calculator. Select your unit (g, oz, lb, or cup) and hit Calculate.
- Read the result. The calculator shows protein content for your exact portion.
- Compare servings. Use the serving range table below to quickly compare protein across portion sizes.
- Log to your tracker. Enter the raw weight and raw entry in your nutrition app for consistent macro tracking.
Why Volume ≠ Weight: Tomato Density Explained
Tomato has a medium density (950 kg/m³). A 1-cup measure holds approximately 225 g.
Why does density matter? The same volume can hold very different amounts of food depending on how dense it is. Oats (350 kg/m³) are light and airy — 1 cup = ~80 g. Water has a density of 1000 kg/m³ — 1 cup = 236 g. This is why nutrition labels use weight (grams), not volume — it's a more reliable measure.
Formula: mass (g) = volume (mL) × density (kg/m³) ÷ 1,000. This calculator uses this formula automatically when you enter a volume measure for Tomato.

Data Sources & Methodology
Data source: USDA FoodData Central.
Computation method: Macro values are calculated by multiplying the food's per-100g value by the requested weight in grams, then dividing by 100. Volume inputs are first converted to grams using the food's density (kg/m³) from USDA data, then the same formula applies: protein = (weight_g / 100) × proteinPer100g.
Accuracy note: Macro values represent averages across measured samples; individual items may vary ±5–10% depending on brand, farming method, and preparation technique. For clinical nutrition, consult a registered dietitian.
Update policy: Macro values are reviewed quarterly against USDA FoodData Central updates. Page last verified: 2026.
