Feta cheese is a crumbly, tangy, and flavorful staple of Greek and Mediterranean cuisine. Made traditionally from sheep's milk or a blend with goat's milk, it's known for its creamy texture and sharp, salty taste. In moderation, it offers beneficial nutrients like calcium, protein, and probiotics. However, the key phrase here is 'in moderation.' Overindulging in feta can lead to a host of health problems, primarily due to its high sodium and saturated fat content.
The Primary Concern: High Sodium Content
Feta cheese is notoriously high in sodium, largely due to the brine it's aged in. A single ounce (28 grams) can contain over 300 milligrams of sodium, a significant percentage of the daily recommended limit.
The Link Between Salt and Blood Pressure
Eating a lot of feta regularly can significantly increase your daily sodium intake, contributing to elevated blood pressure (hypertension). High blood pressure is a major risk factor for serious health issues such as heart disease, stroke, and kidney disease. This is especially concerning for individuals who already have or are at risk of these conditions. For those who can't resist the salty taste, soaking the cheese in water for a few minutes before eating can help reduce the sodium content.
Navigating Saturated Fats and Calories
Like many cheeses, feta contains saturated fat and is calorie-dense. While it is generally lower in fat than many other types of cheese, consistently consuming large portions can still negatively impact your health.
Weight Gain and Cardiovascular Health
An overabundance of saturated fat in your diet can lead to increased cholesterol levels, which contributes to a higher risk of cardiovascular problems. Since feta is calorie-dense, eating large amounts frequently can also lead to weight gain if not balanced with an active lifestyle. Portion control is therefore crucial for maintaining a healthy weight and heart.
Digestive Impact and Lactose Intolerance
For individuals with lactose intolerance, consuming a lot of feta can cause significant digestive distress. As an unripened cheese, it contains more lactose than hard, aged cheeses like Parmesan or Cheddar. This can lead to unpleasant symptoms such as:
- Bloating
- Gas
- Stomach cramps
- Diarrhea
Less Common Risks and Considerations
While less common, there are other potential issues with overconsuming feta cheese that specific individuals should be aware of.
Tyramine and MAOI Medications
Feta, being an aged and fermented food, contains tyramine. This naturally occurring substance can cause blood pressure spikes, heart palpitations, and severe headaches in people taking monoamine oxidase inhibitor (MAOI) medications, which are prescribed for certain forms of depression or Parkinson's disease.
Unpasteurized Feta Risks (Listeria)
Soft, unpasteurized cheeses, including some types of feta, can carry the Listeria monocytogenes bacteria. While harmless to most healthy adults, it can cause mild flu-like symptoms. The bacteria is especially dangerous for pregnant women, as it can harm the fetus. Pregnant women should always ensure they only consume feta that is made from pasteurized milk.

| Probiotics | Yes (strain dependent) | No/minimal | Often fortified |
How to Enjoy Feta in Healthy Moderation
To continue enjoying feta's unique flavor without the health risks of overconsumption, consider these strategies:
- Use it as a garnish: Instead of a main ingredient, use a small amount of crumbled feta to add a powerful flavor to salads, roasted vegetables, or pasta dishes.
- Rinse the brine: Briefly soaking feta in cold water can significantly reduce its sodium content.
- Portion control: A 30g portion is considered a standard serving size. Measuring your intake can help you stay within healthy limits.
- Pair with potassium-rich foods: Counteract high sodium intake by pairing feta with potassium-rich foods like leafy greens, tomatoes, and cucumbers in a Greek salad.
- Choose alternatives: If high sodium is a major concern, explore lower-sodium cheeses or flavor alternatives. Find more information on cheese nutrition and health from reputable sources, like the British Heart Foundation website.
Conclusion: Moderation is Your Best Ingredient
Feta cheese is a delicious and nutritious addition to a balanced diet, offering bone-building calcium and gut-friendly probiotics. However, the consequences of eating too much feta, including high sodium and saturated fat intake, can seriously impact your cardiovascular and digestive health. As with any rich food, the key to enjoying feta lies in moderation and mindful consumption. By being conscious of portion sizes and preparation methods, you can savor its distinct flavor while protecting your long-term health.
Enjoying feta as a flavor enhancer rather than a main component allows you to benefit from its nutritional value without the associated risks of overindulgence.
