Koosa, also known as Mexican or grey squash, is a mild-flavored summer vegetable frequently used in Mediterranean and Middle Eastern cuisine. It is most famously prepared in dishes like kousa mahshi, where it is hollowed out and stuffed with a savory filling. For those tracking their macronutrient intake, especially plant-based eaters, understanding the protein contribution of individual vegetables is key. While koosa isn't a protein powerhouse, its overall nutritional profile makes it a healthy addition to any meal.
Koosa's Protein Content: What the Numbers Say
When examining the raw nutritional data, it becomes clear that koosa is not a significant source of protein. A 100-gram serving of raw summer squash contains approximately 1.2 grams of protein. This is comparable to the protein content of zucchini, which is a very similar squash variety. This low concentration is typical for water-rich, non-starchy vegetables. For context, a 100-gram serving of cooked lentils offers significantly more protein, at around 9 grams. Therefore, while it contributes to your daily intake, koosa should be considered a nutrient-rich filler rather than a primary protein source.
Beyond Protein: Koosa's Comprehensive Nutritional Profile
Despite its modest protein count, koosa is packed with other essential vitamins and minerals that support overall health. Its skin, in particular, is rich in nutrients and antioxidants. Here are some of the key nutrients found in a typical serving:
- Vitamin A and C: Important antioxidants that support immune function and eye health.
- Potassium: An electrolyte that plays a vital role in heart health and blood pressure regulation.
- Magnesium: Supports bone health and metabolic function.
- Dietary Fiber: Promotes healthy digestion and can aid in weight management by increasing satiety.
- Antioxidants (Lutein and Zeaxanthin): Compounds that accumulate in the retina and protect against age-related eye conditions.
Boosting Protein in Koosa-Based Dishes
Since koosa on its own is not a high-protein food, the best strategy for creating a protein-rich meal is to incorporate it with other ingredients. Traditional Middle Eastern recipes already provide excellent examples of this practice. For instance, the stuffing in kousa mahshi is typically made with ground beef or lamb mixed with rice, transforming the dish into a complete and hearty meal.
To make a vegetarian version, you can adapt the stuffing with plant-based proteins. The search results offer several great options. Combining koosa with legumes like chickpeas or lentils, for example, creates a complete protein profile. Other excellent choices include using a tofu crumble or adding nuts and seeds. The versatility of koosa makes it a perfect canvas for incorporating various high-protein ingredients to suit any dietary preference.
Koosa vs. Other Vegetables: A Protein Comparison
The table below compares the protein content of raw koosa (summer squash) with other common vegetables, based on a 100-gram serving. This provides a clearer perspective on its place in a protein-conscious diet.
| Vegetable | Protein Content (per 100g raw) | Notes | 
|---|---|---|
| Koosa (Summer Squash) | ~1.2 g | A low-calorie, hydrating vegetable with fiber and vitamins. | 
| Zucchini | ~1.2 g | Almost identical to koosa in protein and overall nutritional profile. | 
| Lentils | ~9 g (cooked) | A legume and excellent plant-based source of protein and fiber. | 
| Spinach | ~2.9 g | Offers more protein than squash, along with iron and other minerals. | 
| Broccoli | ~2.8 g | A good source of protein, fiber, and Vitamin C. | 
| Edamame | ~11 g (cooked) | A top-tier plant-based protein source and complete protein. | 
Conclusion: The Final Word on Koosa and Protein
In conclusion, koosa is not a significant source of protein, providing only a small amount per serving. However, it is an exceptionally nutritious food, rich in vitamins, minerals, and antioxidants, and high in water and fiber. Its low-calorie and hydrating properties make it a healthy addition to any meal plan. For those seeking to increase their protein intake, koosa serves as an excellent, versatile base that can be paired with high-protein ingredients like meat, legumes, or nuts. Its nutritional benefits extend far beyond a single macronutrient, supporting digestion, eye health, and weight management. It's a prime example of a food that contributes to overall wellness through a wide array of beneficial compounds rather than one dominant macronutrient.
