This calculator helps you determine the protein content in couscous per 100 grams, based on the type of couscous and cooking method. Whether you're tracking macronutrients for a high-protein diet, meal prepping, or simply curious about the nutritional profile of this versatile grain, our tool provides accurate estimates using standard USDA data.
Couscous is a staple in North African cuisine and a popular carbohydrate source worldwide. While it's primarily known for its carbohydrate content, the protein level varies between whole-wheat, pearl, and instant varieties. This calculator accounts for those differences and also adjusts for dry vs. cooked weight, giving you a reliable protein-per-100g figure for your specific needs.
🥣 Couscous Protein Per 100g
How to Use This Tool
Select the type of couscous you have from the dropdown — options include dry whole-wheat, dry regular, cooked whole-wheat, cooked regular, dry pearl (Israeli), and cooked pearl. Enter the weight in grams (default is 100 g). Use the quick-fill buttons to instantly set common weights. Click "Calculate Protein" to see the protein content per 100 g and the total protein for your specified weight. Use "Reset" to clear and start over.
Formula Explained
The calculation uses standard protein density values (grams of protein per 100 g) derived from USDA FoodData Central. For a given weight, total protein = (protein per 100 g × weight in grams) / 100. For example, dry whole-wheat couscous has about 14.5 g protein per 100 g; for 150 g, total protein = (14.5 × 150) / 100 = 21.75 g.
Protein values used (per 100 g): Dry whole-wheat: 14.5 g, Dry regular: 12.8 g, Cooked whole-wheat: 4.3 g, Cooked regular: 3.8 g, Dry pearl: 12.0 g, Cooked pearl: 3.5 g. These are averages; actual values may vary by brand and preparation.
Worked Examples
Example 1: You have 200 g of dry regular couscous. Protein per 100 g = 12.8 g. Total protein = (12.8 × 200) / 100 = 25.6 g.
Example 2: You have 250 g of cooked whole-wheat couscous. Protein per 100 g = 4.3 g. Total protein = (4.3 × 250) / 100 = 10.75 g.
Example 3: You have 80 g of dry pearl couscous. Protein per 100 g = 12.0 g. Total protein = (12.0 × 80) / 100 = 9.6 g.
Tips & Best Practices
- Weigh couscous dry before cooking for accurate tracking — water absorption dilutes protein density.
- If using cooked couscous, ensure it's not packed with oil or butter, which can alter the protein percentage slightly.
- For meal prep, calculate protein per serving by dividing total protein by number of servings.
- Combine couscous with legumes (chickpeas, lentils) or dairy to create a complete protein profile.
Factors Affecting Accuracy
Protein content can vary by brand, growing conditions, and processing methods. The values used are USDA averages. For precise tracking, check the nutrition label on your specific product. Cooking time and water ratio also affect the final weight and thus the protein density per gram of cooked couscous.
Frequently Asked Questions
Is couscous a good source of protein? Couscous provides moderate protein — about 12–14 g per 100 g dry, which is similar to other grains like quinoa (14 g) but less than legumes. It's not a complete protein (lacks some essential amino acids), but pairing it with beans or dairy makes it complete.
Does cooking reduce protein? No, cooking does not destroy protein, but it adds water weight, so the protein per 100 g of cooked couscous is lower (around 3.5–4.3 g). The total protein remains the same if you measure dry weight before cooking.
Can I use this for gluten-free diets? Traditional couscous is made from wheat (semolina) and contains gluten. Gluten-free alternatives (e.g., corn or rice couscous) have different protein values — this calculator is for wheat-based couscous only.
How does pearl couscous compare? Pearl (Israeli) couscous is larger and toasted, giving it a slightly lower protein density (12.0 g dry, 3.5 g cooked) compared to regular couscous.
