Mushroom Protein — Frequently Asked Questions

How much protein is in 100g of Mushroom? 100g of Mushroom contains 3.1 g of protein (USDA FoodData Central). This is a low-protein food.

How much protein in one Mushroom? A typical mushroom weighs about 18g and contains 0.6 g of protein. This is calculated as 18g ÷ 100 × 3.1 = 0.6 g.

How much protein is in 1 cup of Mushroom? One US cup of mushroom weighs approximately 83g (density: 350 kg/m³). That serving contains 2.6 g of protein — computed as 83g ÷ 100 × 3.1.

How many grams of Mushroom do I need to eat to get 30 g of protein? To reach 30 g of protein from Mushroom, you need approximately 968g — calculated as (30 ÷ 3.1) × 100 = 968g.

Is Mushroom high in protein? Mushroom is low in protein at 3.1 g per 100g. If you're targeting this nutrient, Mushroom alone is unlikely to be sufficient.

What percentage of daily protein does 100g of Mushroom provide? 100g of Mushroom provides 3.1 g of protein, which is 6.2% of the reference daily intake (50 g/day for adults, based on a 2000-calorie diet). To reach 100% of your daily protein from Mushroom alone, you would need ~1613g.

How efficient is Mushroom as a source of protein per calorie? Mushroom provides 14.09 g of protein per 100 kcal, making it excellent as a protein-per-calorie source. This is useful for calorie-restricted diets where macronutrient density matters.

What formula does this Mushroom protein calculator use? The calculator uses protein = weight in grams / 100 x 3.1 g. For example, 100g of Mushroom gives 3.1 g of protein. Volume entries are first converted to grams using the food density value, then the same per-100g formula is applied.

Is Mushroom a good food for muscle building or high-protein goals? For muscle building or high-protein goals, Mushroom is a modest contributor — with 3.1 g of protein per 100g. For best results, combine Mushroom with other foods to hit your daily macro targets.

How reliable is the source data for Mushroom? Mushroom 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 Mushroom Protein

Weigh raw. Place your mushroom 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: Mushroom Density Explained

Mushroom is very light (350 kg/m³ — about 0.35× the density of water), so a 1-cup measure holds only ~83 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 Mushroom.

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.
