The Source of Sugars in Feta: A Fermentation Story
All cheese begins with milk, which contains a natural sugar called lactose. For most cheese production, including traditional feta, a fermentation process takes place where lactic acid bacteria consume most of this lactose. This bacterial action converts the milk sugar into lactic acid, which is essential for giving the cheese its tangy flavor and helping to form the curds. Because of this process, the final product contains only trace amounts of residual lactose, which is why most people following a low-sugar or low-carb diet can enjoy it.
Feta's Distinctive Process
Authentic feta, protected by EU Designation of Origin (PDO) status, is made predominantly from sheep's milk, or a mixture of sheep's and goat's milk. This milk, combined with the specific brining and aging process, further reduces the sugar content. The brining not only adds the characteristic salty flavor but also contributes to the preservation and development of the cheese's final texture and flavor profile.
Feta's Nutritional Profile: A Detailed Look
As a low-sugar cheese, feta fits well into many dietary regimens. A standard 1-ounce (28-gram) serving offers a beneficial mix of fats and protein with minimal carbohydrates and sugars.
- Calories: Approximately 76.
- Protein: Around 5.3 grams.
- Fat: Roughly 5.3 grams.
- Carbohydrates: About 1.56 grams, with sugars making up less than half of this.
- Sodium: A significant amount, which is a key nutritional aspect to monitor.
Beyond its macronutrient composition, feta is also a good source of several important micronutrients. It is particularly rich in calcium and phosphorus, which are vital for bone health. It also contains beneficial probiotics, which can contribute to a healthy gut microbiome.
How Feta's Sugar Content Compares to Other Cheeses
It's helpful to see how feta stacks up against other popular cheeses in terms of sugar and carbohydrate content, especially for those watching their intake.
| Cheese Type | Estimated Sugar per Ounce | Carbs per Ounce | Dietary Suitability | Notes |
|---|---|---|---|---|
| Feta | ~0.5g | ~1.5g | Low-carb, Keto | Minimal residual lactose. |
| Goat Cheese (soft) | 0g | 0g | Very Low-Carb, Keto | Very little to no lactose remains. |
| Cheddar | ~0.6g | ~0.6g | Low-carb, Keto | Varies slightly based on aging. |
| Ricotta (Part-Skim) | ~1.5g | ~1.5g | Moderate Carb | Fresher cheese, more lactose retained. |
| Mozzarella | ~0.6g | ~0.6g | Low-carb, Keto | Also low in carbs. |
As the table shows, feta's sugar content is on par with many other popular low-carb cheeses. The key is that the fermentation process for these aged or brined cheeses significantly reduces the naturally occurring milk sugar.
Feta and Low-Carb Diets
For those following a ketogenic or other low-carb diet, feta is an excellent choice. Its high fat and moderate protein content provide satiety, helping to reduce cravings for high-carb foods. The low sugar profile ensures it won't cause a significant spike in blood sugar, which is a primary goal of these eating plans. Its distinct, salty flavor also allows a small amount to go a long way, adding a burst of taste to dishes without adding a lot of calories.
Tips for Incorporating Feta into Your Low-Sugar Diet
- Salad Topping: Sprinkle crumbled feta over fresh greens, cucumbers, and tomatoes for a classic Mediterranean salad. The tangy flavor is a perfect counterpoint to crisp vegetables.
- Roasted Vegetables: Toss roasted vegetables like bell peppers, zucchini, or broccoli with olive oil and crumbled feta for a simple, flavorful side dish.
- Omelets and Scrambles: Mix feta into your morning eggs for a protein-packed and satisfying start to the day. The saltiness can replace the need for extra seasoning.
- Pizza Topping: Use feta as a pizza topping alongside other low-carb ingredients like olives, spinach, and mushrooms.
- With Olives: Serve a block of feta with a drizzle of high-quality olive oil and some mixed olives as an elegant and simple appetizer.
Authenticity Matters: Greek Feta vs. Imitations
The quality and composition of feta can vary widely. Authentic Greek feta is a Protected Designation of Origin (PDO) product, ensuring it's made from sheep's milk or a mix with up to 30% goat's milk and aged in brine. Imitation feta, often made with cow's milk, may have a different flavor, texture, and potentially different sugar content. While still low-carb, it's worth checking the label to understand exactly what you're buying. Real Greek feta has a richer, more complex flavor profile due to the milk source and traditional process.

Conclusion
In conclusion, while feta is made from milk that contains sugar (lactose), the fermentation process dramatically reduces this content. The final product is a low-sugar, low-carb cheese that is a healthy and flavorful addition to many diets, including low-carb and keto plans. It offers important nutrients like calcium and protein and can be a versatile ingredient in various dishes. For the best flavor and nutritional benefits, opt for authentic Greek feta and remember that due to its sodium content, moderation is key.
