Unpacking the Nutritional Profile of Feta
Feta cheese is a soft, brined cheese traditionally made from sheep's milk, or a mixture including up to 30% goat's milk. Unlike many aged cheeses, it is lower in calories and fat, yet packed with essential nutrients. A typical 1-ounce (28g) serving contains approximately 74–76 calories, 4–5 grams of protein, and 5–6 grams of fat. However, it is also notable for its high sodium content, which comes from the brine used for aging. For example, one ounce can contain over 300 mg of sodium, or more than 13% of the Daily Value.
The Health Benefits of Greek Feta
Beyond its fundamental nutritional makeup, Greek feta offers several key health advantages when consumed in moderation.
- Bone Health: Feta is an excellent source of calcium and phosphorus, two minerals vital for building and maintaining strong bones. Studies suggest that calcium from dairy sources may be particularly effective for bone density.
- Probiotic Power: As a fermented food, feta contains beneficial microbes like Lactobacillus plantarum. These probiotics are known to support gut health by protecting the intestinal tract from harmful bacteria and promoting a balanced gut microbiome.
- Beneficial Fatty Acids: Feta cheese contains conjugated linoleic acid (CLA), a fatty acid that studies suggest may help improve body composition by reducing body fat and increasing lean mass. Feta made with sheep's milk has higher CLA concentrations.
- Easier Digestion: For those with mild lactose intolerance, feta can be easier to digest than cow's milk cheeses. This is because it is traditionally made from sheep's and goat's milk, which contain different protein structures and lower lactose levels.
- High-Quality Protein: Feta is a good source of high-quality protein, which is essential for muscle maintenance and repair. Protein also contributes to a feeling of fullness, which can support weight management.
Risks and Considerations
While healthy for most people, feta does come with some potential downsides that require moderation, particularly for certain individuals.
- High Sodium: The high sodium content is perhaps the most significant drawback. Excessive sodium intake can contribute to high blood pressure, kidney disease, and heart issues. Individuals with hypertension should be particularly mindful of their intake.
- Saturated Fat: Feta contains saturated fat, and while its levels are lower than many aged cheeses, it is still a consideration for those monitoring their fat intake.
- Listeria Risk for Pregnant Women: Unpasteurized feta cheese poses a risk of carrying the Listeria bacteria, which can be dangerous for pregnant women and their babies. It is crucial for expectant mothers to only consume feta that is made from pasteurized milk.
- Tyramine Content: Some aged or fermented foods, including feta, contain tyramine, which can trigger headaches or blood pressure spikes in individuals taking monoamine oxidase inhibitor (MAOI) drugs.

How to Incorporate Feta Healthily
Including feta in your diet can be a delicious way to boost nutrient intake without excessive calories, provided you control portion sizes. Consider these methods:
- Salads: Crumble feta over a classic Greek salad with fresh tomatoes, cucumbers, and olives. Its bold flavor means you can use less while still getting a tasty result.
- Baked Dishes: Bake a block of feta with cherry tomatoes and herbs for a warm, delicious dip or sauce. This can be served with toasted whole-grain bread or zucchini noodles.
- Breakfast: Mix crumbled feta into scrambled eggs or an omelet with spinach for a savory, high-protein start to your day.
- Wraps and Sandwiches: Add a small amount of feta to a wrap with grilled chicken and plenty of fresh vegetables for an extra flavor kick.
- Straining the Brine: For a quick and easy way to reduce sodium, rinse the feta under cold water for a few minutes before eating.
Conclusion: Is Feta a Healthy Choice?
Overall, Greek feta can be a very healthy and flavorful addition to a balanced diet, offering impressive amounts of calcium, protein, and beneficial probiotics. Its placement as a staple in the Mediterranean diet speaks to its value. However, the key to its healthiness lies in moderation, primarily due to its high sodium content. By being mindful of portion sizes and using it as a flavor enhancer rather than a main ingredient, you can enjoy the many benefits of Greek feta while mitigating its potential drawbacks. Always check if the feta is pasteurized, especially if you are pregnant, to avoid the risk of Listeria. Feta is a delicious and nutritious choice for most, embodying the balance of healthy and satisfying eating.
