Pumpkin is one of fall's most versatile ingredients, but its protein content is often overlooked. Whether you are roasting cubes, stirring canned purée into oatmeal, or snacking on seeds, this pumpkin protein calculator tells you exactly how many grams of protein are in your serving. Enter the amount, choose the unit, and select the pumpkin form that matches what you are eating.
The protein values used here are based on USDA FoodData Central reference data. Alongside the protein total, the tool reports the calories coming from protein and the percentage of the Daily Value covered by the serving. It is a practical companion for macro tracking, vegetarian meal planning, and anyone who wants a clearer picture of this popular winter squash.
No kitchen scale? The quick-size buttons add common portions such as a cup of canned pumpkin or an ounce of roasted seeds automatically, making the calculator just as useful for quick estimates as for precise logging.
🎃 Pumpkin Protein Calculator
Find out how much protein is in raw, cooked, canned pumpkin, or roasted pumpkin seeds.
Quick Start Guide
Using the calculator takes three steps. First, type the amount you plan to eat into the serving box. Second, set the unit to grams, ounces, pounds, or kilograms. Third, choose the pumpkin form from the dropdown — raw, boiled/cooked, canned purée, or roasted hulled seeds — and press Calculate protein. The result card shows the protein in your serving, the protein per 100 g, the calories from protein, and how much of your daily protein target the serving covers.
If you prefer to work with common portions, use the quick-size buttons. They prefill the serving amount and unit for a 100 g portion, a cup of canned pumpkin, half a cup of canned pumpkin, or an ounce of pumpkin seeds. You can still change the amount and form after selecting a preset.
Tip: For the most accurate numbers, weigh the pumpkin on a food scale and use grams. Volume estimates are convenient, but cubes, purée, and flesh can pack differently.
How the Calculation Works
The calculator converts your serving to grams if needed, then applies a simple proportion:
Protein (g) = (serving weight in grams ÷ 100) × protein per 100 g
For example, 1 ounce equals 28.35 g. If you select canned pumpkin with 1.1 g protein per 100 g, the calculation is (28.35 ÷ 100) × 1.1 = 0.31 g protein. Protein calories are then estimated by multiplying grams of protein by 4 kcal per gram. The Daily Value comparison uses 50 g of protein per day as the reference on nutrition labels in the United States.
The underlying protein figures are drawn from USDA FoodData Central entries for raw pumpkin, boiled pumpkin, canned pumpkin, and roasted pumpkin seed kernels. Values can vary slightly by variety, growing conditions, and preparation method. You can browse the USDA database directly at fdc.nal.usda.gov and read FDA's current daily value guidance at fda.gov.
Worked Examples
Example 1: Canned pumpkin in a smoothie. You blend 120 g of canned pumpkin. Protein = (120 ÷ 100) × 1.1 = 1.32 g. Protein calories = 1.32 × 4 = 5.3 kcal, and the serving covers 1.32 ÷ 50 = 2.6% of the Daily Value.
Example 2: Roasted pumpkin seed snack. You eat a 28 g packet of hulled roasted seeds. Protein = (28 ÷ 100) × 29.8 = 8.34 g. Protein calories = 8.34 × 4 ≈ 33.4 kcal, or about 16.7% of the Daily Value.
Example 3: Roasted pumpkin cubes. A side dish uses 200 g of cooked pumpkin. Protein = (200 ÷ 100) × 0.72 = 1.44 g. This is close to 3% of the Daily Value and contributes about 5.8 kcal from protein.
Reference: Protein in Common Pumpkin Products
The table below summarizes typical values based on USDA data. Use them as a quick guide when you do not have the calculator open.
| Pumpkin form | Protein per 100 g | Common portion | Protein in that portion |
|---|---|---|---|
| Raw pumpkin flesh | 1.0 g | 1 cup cubes (≈116 g) | ≈1.2 g |
| Boiled/drained pumpkin | 0.72 g | 1 cup mashed (≈245 g) | ≈1.8 g |
| Canned pumpkin purée | 1.1 g | 1 cup (≈245 g) | ≈2.7 g |
| Roasted pumpkin seeds, hulled | 29.8 g | 1 oz (≈28 g) | ≈8.4 g |
Notice that pumpkin flesh is not a protein-dense food. The seeds, on the other hand, are one of the best plant-based sources of protein and also provide magnesium, zinc, and healthy fats. If your goal is to raise protein intake while keeping pumpkin on the menu, seeds are the highest-yield choice.
Tips for Accurate Macro Tracking
- Weigh before cooking. Raw pumpkin loses water as it cooks, so 100 g of raw cubes becomes less than 100 g of cooked pumpkin. If you log a cooked portion, use the cooked value from the dropdown.
- Read the label for canned pumpkin. Some canned products are pumpkin pie mix with added sugar and other ingredients. Plain canned pumpkin is the closest match to the 1.1 g per 100 g figure.
- Use the right seed value. Pumpkin seeds with the shell still attached weigh more but contain less protein per 100 g than shelled kernels. This calculator uses hulled roasted kernels.
- Pair pumpkin with a protein source. Because pumpkin flesh is mostly water and carbohydrates, combine it with Greek yogurt, cottage cheese, eggs, beans, or tofu for a more balanced meal.
Frequently Asked Questions
Is pumpkin a good source of protein? Pumpkin flesh is not a concentrated protein source — a typical serving provides only 1–3 g. Pumpkin seeds are the exception: a single ounce can supply 8–9 g of protein, which compares well with nuts and other seeds.
Should I use raw or cooked pumpkin values? The best choice depends on how you eat it. Boiled or steamed pumpkin is mostly water and has a lower protein concentration per 100 g than raw pumpkin. If you roast pumpkin until it reduces, the cooked form is more appropriate.
Why does the label on my pumpkin product differ? Different pumpkin varieties, pumpkin-to-water ratios in canned products, and added ingredients change the nutrition profile. The calculator uses standard reference values, not manufacturer-specific labels.
Is pumpkin protein complete? The amino acid pattern in pumpkin flesh is not considered complete on its own, but seeds contain a respectable range of amino acids. In the context of a varied diet that includes legumes, whole grains, nuts, and dairy or soy, protein quality is usually not a concern.
