A standard serving of feta cheese is typically defined as 1 ounce, or approximately 28 grams. This small but flavorful portion is enough to add a distinct tangy, salty kick to salads, omelets, and other dishes without overloading on calories or sodium. While some nutritional labels may specify a 1.5-ounce serving size, the 1-ounce measurement is a widely accepted and practical amount for healthy eating, especially given feta’s intense flavor profile. Adhering to this serving size is a key strategy for managing overall intake of this calorie-dense, though nutritious, cheese. For at-home measurement, one ounce of crumbled feta is roughly equivalent to a quarter cup.
The Nutritional Profile of a Feta Serving
Beyond just its size, understanding the nutritional components of a 1-ounce serving helps illustrate its role in a balanced diet. Feta cheese is known for its beneficial nutrients, but also its high sodium content due to the brining process.
Macronutrient Breakdown
- Calories: Approximately 74–76 calories per 1-ounce serving.
 - Protein: Provides about 4 to 5.3 grams of protein, essential for muscle health.
 - Fat: Contains around 5.3 to 6.5 grams of fat, of which a significant portion (about 4 grams) is saturated fat.
 - Carbohydrates: Very low in carbs, with approximately 1 to 1.5 grams per serving, making it suitable for low-carb and keto diets.
 
Vitamins and Minerals
Feta is a rich source of several key nutrients. A single serving provides valuable amounts of:
- Calcium: Supports bone density and strength, with around 14% of the daily recommended intake.
 - Vitamin B12: Crucial for nerve function and the production of red blood cells.
 - Phosphorus: Works with calcium to support bone health.
 - Selenium: An important antioxidant that protects cells from damage.
 
The Sodium Factor
The high sodium content is a primary reason for careful portion control. A 1-ounce serving can contain anywhere from 258 to 364 mg of sodium, which helps with its preservation. Individuals with high blood pressure or those on a sodium-restricted diet should be particularly mindful. One way to mitigate this is to rinse the cheese with water before eating.
Feta vs. Other Popular Cheeses: A Comparison Table
Comparing feta to other popular cheeses can highlight why moderation is key. Here is a nutritional comparison based on a 1-ounce (28g) serving:
| Cheese Type | Calories (approx.) | Fat (g) | Protein (g) | Sodium (mg) | Notes | 
|---|---|---|---|---|---|
| Feta | 75 | 6 | 4 | 360 | Lower in fat than many aged cheeses, but high in sodium. | 
| Cheddar | 110 | 9 | 7 | 170 | Higher in calories and fat, but lower in sodium. | 
| Part-Skim Mozzarella | 85 | 6 | 6 | 150 | Similar fat content to feta but lower in calories and sodium. | 
Why Portion Control Matters for Feta
Due to its distinct flavor and nutritional profile, controlling your feta intake offers several health advantages:
Managing Sodium Intake
Consuming excessive sodium can lead to health issues like high blood pressure, and feta's brining process makes it a high-sodium food. Sticking to a single serving helps keep your daily sodium levels in check, supporting heart health and overall well-being.
Weight Management
While not as high in fat as some hard cheeses, feta is still a calorie-dense dairy product. Its healthy fats contribute to feelings of fullness, but consuming too much can quickly increase your overall calorie intake. Using a standard serving ensures you reap the flavor and nutritional benefits without derailing weight-loss efforts.
Flavor Intensity
Feta has a powerful, tangy flavor. A little goes a long way, and a single 1-ounce serving is typically sufficient to enhance the taste of a dish. This makes it an efficient and delicious ingredient for adding flavor without needing large quantities.
How to Measure Feta Cheese at Home
Accurately measuring your feta serving is simple with a few kitchen tools:
- Digital Food Scale: The most accurate method is to weigh out 28 grams directly. For precision in nutrition tracking, a scale is the best option.
 - Measuring Cups: For crumbled feta, a quarter-cup is a reliable approximation for a 1-ounce serving.
 - Visual Estimation: While less precise, you can visualize an ounce of feta as a small block roughly the size of a few dice.
 - Pre-portioned Packs: Some brands sell feta in pre-portioned containers, making it easy to grab a standard serving without any measuring.
 
Healthy and Flavorful Uses for Feta
Incorporating a mindful portion of feta into your meals is easy and delicious. Its crumbly texture and tangy taste complement a wide variety of ingredients. Here are some simple ideas to use your standard serving:
- On Salads: Crumbled feta is a classic topping for Greek salads, offering a perfect contrast to crisp vegetables and briny olives.
 - In Baked Dishes: Use it to top baked chicken or pasta dishes for a salty, creamy finish, like a simple tomato and feta pasta.
 - With Roasted Vegetables: Sprinkle feta over roasted vegetables such as bell peppers, zucchini, or eggplant for a flavor boost.
 - In Dips and Spreads: Blend it with yogurt and herbs to create a flavorful dip for vegetables or pita bread. This approach helps the serving stretch further while incorporating probiotics.
 - On Pizza or Flatbread: A small amount of feta on a homemade pizza or flatbread adds a gourmet touch with minimal extra calories.

Conclusion
Understanding what is a serving size of feta cheese is straightforward, with a 1-ounce (28-gram) portion being the standard.
