You’re standing in the dairy aisle, looking at that block of white, crumbly goodness. Feta is a staple. It’s the soul of a Greek salad and the salty kick your avocado toast desperately needs. But if you’ve ever felt like your rings were a bit tighter the morning after a feta-heavy dinner, you’re not imagining things. How much sodium in feta cheese is actually lurking behind that tangy flavor? It’s a lot. Honestly, it’s usually way more than people realize because feta isn't just a cheese; it’s a cheese preserved in a salty bath.
Most standard brands pack about 310 to 320 milligrams of sodium into a single one-ounce serving. That’s roughly 13% to 14% of your total daily limit in a piece the size of a pair of dice.
Does that mean it’s "bad"? Not necessarily. But for anyone watching their blood pressure or trying to cut back on processed foods, that tiny cube is a concentrated salt bomb. It’s a brine-cured cheese. The salt isn't just there for taste—it’s the preservative that keeps the cheese from spoiling and gives it that signature sharp bite. If you’re eating out and a chef tosses a handful of crumbles onto your plate, you could easily be consuming 600mg or more of sodium before you even touch the rest of your meal.
What Determines How Much Sodium in Feta Cheese You're Actually Eating?
Not all feta is created equal. The traditional Greek stuff—the "Protected Designation of Origin" (PDO) feta—is made from sheep’s milk or a blend of sheep and goat milk. This type tends to be creamier and, surprisingly, sometimes a bit higher in sodium because it’s aged longer in a more concentrated brine. In contrast, the cow’s milk versions you find in the big plastic tubs at the grocery store might be slightly lower in salt, but they lose that complex, tangy funk.
A study published in the Journal of Food Composition and Analysis highlighted that the salt content in commercial feta can vary by as much as 20% depending on the brand. Some artisanal versions use a dry-salting method before brining, which can push those numbers even higher. It’s a wild west of sodium counts out there.
Then you have the "low-sodium" versions. They exist. They’re usually labeled as "reduced sodium," and they aim for about 25% less salt. The problem? Feta relies on salt for its structural integrity. When you pull the salt out, the texture often turns a bit rubbery or bland. You win on the heart health front, but you might lose on the culinary one.

The Brine Factor
Why is it so salty? It’s all about the soak. Feta is a "pickled" cheese. After the curds are formed and pressed, the cheese sits in a saltwater solution (brine) for weeks or months. This prevents the growth of bad bacteria. It also means the salt permeates every single molecule of the cheese. Unlike a hard cheese like Parmesan where the salt is concentrated, feta is literally saturated.
Comparing Feta to Other Popular Cheeses
If you're trying to figure out where feta sits on the spectrum, it's pretty high up there. Let's look at the numbers.
- Feta: ~316mg per ounce
- Halloumi: ~350mg per ounce (The absolute king of salt)
- Mozzarella: ~175mg per ounce (The gentle giant)
- Swiss: ~50mg per ounce (Practically salt-free by comparison)
- Cheddar: ~180mg per ounce
Basically, feta is nearly double the saltiness of cheddar. If you’re swapping out your usual morning cheddar for feta because you think it’s "lighter" or "healthier," you’re actually jacking up your sodium intake significantly. People often associate white cheeses with being healthier or lower in fat, which can be a trap. While feta is lower in calories than some aged yellow cheeses, the sodium trade-off is the real story here.
The Health Implications of High Sodium Feta
We’ve all heard the warnings. Too much salt leads to hypertension. It strains the kidneys. But for some, the concern is more immediate. Edema—that uncomfortable swelling in your hands and feet—can be triggered by a high-sodium meal.
If you have a condition like Chronic Kidney Disease (CKD) or Congestive Heart Failure, how much sodium in feta cheese becomes a life-or-death calculation. The American Heart Association recommends no more than 2,300mg a day, with an "ideal" limit of 1,500mg for most adults. Two ounces of feta puts you at nearly half of that ideal daily limit. That’s a lot of pressure on your cardiovascular system just from a garnish.

However, it’s not all bad news. Feta is a great source of calcium and contains B vitamins and phosphorus. It also contains Lactobacillus plantarum, a probiotic that can be good for gut health. The trick is balancing the mineral wealth against the sodium tax.
Can You Wash the Salt Away?
Here is a pro tip that most people don't know: you can actually lower the sodium yourself. It sounds weird, but it works. If you buy a block of feta in brine, take it out and rinse it under cold water for about 60 seconds. Even better, soak the block in fresh water or milk for 15 to 30 minutes before you eat it.
This won't remove all the salt—remember, it’s soaked all the way through—but it will draw out a significant portion of the surface salt. Chefs in Greece actually do this quite often to mellow out a particularly aggressive batch of cheese. It softens the flavor and makes it much more palatable if you're eating it plain.
How to Eat Feta Without Overdoing the Salt
You don't have to quit feta cold turkey. That would be a tragedy for your salads. Instead, you just have to be a bit more strategic about how you use it.
- Skip the extra salt. This seems obvious, but people forget. If you're putting feta in a dish, you don't need to add table salt to the recipe. The cheese is the salt.
- Go for the block, not the crumbles. Pre-crumbled feta has more surface area exposed to oxygen and often contains anti-caking agents like cellulose. The blocks kept in brine stay fresher and, surprisingly, allow you to control the portion size better.
- Dilute with acid. If you want that sharp "zing" but want to use less cheese, increase the lemon juice or vinegar in your dressing. It mimics the tartness of the feta without the sodium.
- The "Garnish" Rule. Treat feta like a spice, not a main ingredient. A tablespoon of crumbles is often plenty to flavor an entire bowl of grains.
Real-World Example: The Greek Salad Trap
Think about a standard Greek salad at a restaurant. It usually has olives, feta, and maybe some pickled peppers.

- 3 Kalamata olives: ~190mg sodium
- 1 ounce of feta: ~315mg sodium
- Dressing with salt: ~200mg sodium
Before you’ve even had a bite of a cucumber, you’re at 705mg. That’s why being aware of how much sodium in feta cheese is so critical; it’s rarely the only salty thing on the plate. If you’re making it at home, you can skip the olives or use a lower-sodium dressing to balance the "budget" for the cheese you love.
Shopping Smart: What to Look for on the Label
Next time you’re at the store, ignore the "All Natural" or "Traditional" marketing on the front. Flip the package over. Look at the serving size. Most labels use 28g or 1 ounce. If the sodium is over 350mg, put it back. There are better options.
Look for brands that use traditional sheep’s milk. While it might be salty, it’s often more satisfying, meaning you’ll actually eat less of it to get the flavor fix you’re looking for. Cow’s milk feta is often blander, leading people to use twice as much just to taste it. Quality over quantity is the mantra here.
Summary of Actionable Steps
- The Rinse Method: Always rinse your feta under cold water for a minute before serving to shed excess surface brine.
- Portion Control: Use a scale or your thumb as a guide. One ounce is roughly the size of your thumb from the tip to the base.
- Check the Origin: Seek out PDO Greek Feta. It’s richer and more flavorful, allowing you to use less while still enjoying the "feta experience."
- Avoid Pre-Crumbled: These are often saltier and contain additives you don't need.
- The Milk Soak: If a block is too salty to eat, submerge it in a bowl of plain milk for 30 minutes. The milk will draw out the salt without ruining the texture.
Feta is a delicious, ancient food that has a place in a healthy diet. You just have to treat it with a bit of respect for its mineral content. By understanding the sodium load and using tricks like rinsing or "flavor dilution," you can keep the tangy crumble in your life without putting your blood pressure through the wringer.
Next Steps for Your Kitchen
- Check your fridge: Take a look at the nutritional label on your current brand of feta. If it's over 320mg per ounce, consider trying a different brand next time.
- Try the rinse: Tonight, take your feta out of the container and give it a quick 30-second rinse before putting it on your food. Note the difference in how you feel the next morning.
- Balance the meal: If you're having a feta-heavy dish, make sure the rest of your ingredients—like your proteins and grains—are cooked without added salt to keep the total meal sodium in check.
