The Protein Profile of Feta Cheese
Feta cheese is a popular Greek cheese, known for its tangy, salty flavor and crumbly texture. Traditionally made from sheep's milk or a mix of sheep and goat's milk, its nutritional composition offers more than just flavor. While it's certainly a source of protein, understanding its profile requires looking at the serving size and how it's made.
For a standard one-ounce (28-gram) serving, feta cheese provides approximately 4 to 5 grams of protein. A larger 100-gram serving, closer to two-thirds of a cup, contains around 14 to 15 grams of protein. This protein is a complete protein, meaning it contains all nine essential amino acids needed by the body. Like other dairy products, it consists of both casein, which digests slowly, and whey, which is absorbed quickly. Casein helps promote a feeling of fullness, which can be beneficial for weight management. It's worth noting that the protein content can vary slightly depending on the milk source and moisture content of the specific feta.
Feta vs. Other Cheeses: A Protein Comparison
To fully appreciate the protein content of feta, it helps to compare it with other common cheese types. While feta is a good source of protein, it is not the most protein-dense cheese available. Harder, aged cheeses generally have higher protein concentrations because more moisture has been removed during the aging process. The following table compares the protein, fat, and sodium content per 100 grams for several popular cheeses.
| Cheese Type | Protein (per 100g) | Fat (per 100g) | Sodium (per 100g) |
|---|---|---|---|
| Feta | ~14-17g | ~21-23g | ~917-1710mg |
| Parmesan | ~35.8g | ~25.8g | ~390mg (per 1oz) |
| Cottage Cheese | ~11-12g | ~1-4g | ~364-917mg |
| Cheddar | ~24-25g | ~33g | ~185mg (per 1oz) |
| Swiss | ~26-28g | ~27-28g | ~53mg (per 1oz) |
How Feta Stacks Up
Looking at the data, Parmesan cheese is the clear winner for protein density, packing significantly more protein per 100g than feta. However, feta's strong flavor profile means that most people use smaller portion sizes, such as a tablespoon or a light crumble, rather than consuming 100 grams in one sitting. Cottage cheese offers a lower-fat, moderately high-protein option, with a different texture and flavor profile. Therefore, while feta isn't the highest protein cheese, its flavor intensity and versatility make it a valuable and satisfying component of a meal, contributing a meaningful amount of protein without requiring a large serving.
Beyond Protein: Feta's Other Nutritional Benefits
Feta cheese is more than just a source of protein. It offers several other nutritional benefits that contribute to its healthy reputation:
- Bone Health: Feta is rich in calcium and phosphorus, two minerals essential for maintaining strong bones and teeth. Regular consumption of dairy products has been linked to increased bone density and a lower risk of osteoporosis.
- Gut Health: The cheese contains beneficial probiotics, including Lactobacillus plantarum, which can help foster a healthy gut microbiome and support proper digestion.
- Immune System Support: Feta contains histidine, an amino acid that plays a role in boosting the immune system.
- Rich in Vitamins: It is a good source of B vitamins, including B2 (riboflavin) and B12, which are crucial for energy production and nerve function.
- Low in Lactose: Due to its maturation process, feta is naturally low in lactose, making it easier for some people with mild lactose intolerance to digest.
The Sodium Consideration
One significant factor to be aware of when consuming feta is its high sodium content. The cheese is aged in brine, which gives it its characteristic salty flavor. Sodium content can vary widely depending on the brand and how it's prepared. People with high blood pressure or those following a low-sodium diet should be mindful of their intake. To reduce the sodium, some suggest soaking the feta in water for a few minutes before eating.
Incorporating Feta into a High-Protein Diet
Feta is a versatile ingredient that can enhance many dishes while boosting protein intake. Its strong flavor means a little goes a long way. Here are some ideas for adding it to your meals:
- Crumble over a classic Greek salad with tomatoes, cucumbers, and olives.
- Mix into scrambled eggs or an omelet for an extra kick of flavor and protein.
- Combine with spinach and baked into a simple pastry or quiche.
- Sprinkle on top of roasted vegetables or grilled chicken.
- Create a flavorful dip by blending feta with a little olive oil and herbs.
- Stir into quinoa, couscous, or pasta salads for a Mediterranean touch.

Conclusion
While feta cheese provides a valuable source of protein, especially for those seeking to incorporate more into their vegetarian diet, it is not the highest-protein cheese by volume. Aged cheeses like Parmesan or Swiss contain more protein per serving. However, feta's unique tangy flavor, along with its benefits for bone and gut health, make it a nutritious and satisfying addition to any balanced diet, provided it is enjoyed in moderation due to its sodium content. By being mindful of portion sizes and preparation, you can easily enjoy this healthy cheese as part of a high-protein eating plan.
