Feta cheese is a nutritious option that compares favorably to most other cheeses. At 75 calories and 6 grams of fat per ounce, it delivers meaningful protein, calcium, and probiotics with fewer calories than harder cheeses. Its high sodium content is the main nutritional drawback, but for most people, feta in moderate amounts is a smart addition to a balanced diet.
How Feta Compares to Other Cheeses
Feta is one of the lighter cheeses you can choose. A one-ounce serving contains about 75 calories, 6 grams of fat, and 4 grams of protein. Compare that to cheddar, which packs 115 calories and 9 grams of fat in the same serving size. That’s roughly 35% fewer calories and a third less fat, which adds up quickly if you’re using cheese regularly in salads, omelets, or grain bowls.
Part of the reason feta is lower in calories is that it’s a brined, soft cheese with higher moisture content than aged varieties. It also has a strong, tangy flavor, so a little goes a long way. You can crumble a small amount over a dish and get plenty of taste without loading up on calories the way you might with milder cheeses that need to be used more generously.
Calcium and Bone Support
One ounce of feta provides about 140 milligrams of calcium, roughly 14% of what most adults need daily. It also contains about 96 milligrams of phosphorus. Both minerals work together in bone formation. Getting them from the same food is useful because your body needs phosphorus to properly incorporate calcium into bone tissue. For people who eat cheese a few times a week, feta contributes meaningfully to overall calcium intake without the caloric cost of heavier cheeses.
The Sodium Problem
Sodium is the biggest concern with feta. A single ounce contains roughly 375 milligrams, which is about 25% of the recommended daily maximum of 1,500 milligrams set by the American Heart Association as an optimal target for most adults. Even against the more lenient ceiling of 2,300 milligrams per day, one ounce of feta accounts for about 16% of your limit.
That doesn’t make feta unhealthy, but it does mean you need to be aware of what else you’re eating that day. If your meals already include bread, canned foods, condiments, or processed meats, the sodium from feta stacks up fast. Rinsing feta under water before eating it can reduce the surface salt noticeably. You can also soak it in water or milk for 10 to 15 minutes to pull out more of the brine.
Why Feta May Be Easier to Digest
Traditional feta is made from sheep’s milk, goat’s milk, or a combination of both. This matters for digestion. Cow’s milk contains a protein called A1 beta-casein, which breaks down during digestion into a compound that can trigger gastrointestinal discomfort resembling lactose intolerance. In a double-blind study, participants who drank milk containing both A1 and A2 casein reported significantly more digestive discomfort than those who consumed only A2 casein.
Sheep and goat milk naturally contain far more A2 beta-casein and very little A1. That single amino acid difference between the two protein types translates to a real reduction in bloating, gas, and stomach pain for many people. If you’ve noticed that cow’s milk cheese bothers your stomach but haven’t tried feta made from sheep or goat milk, it’s worth experimenting. Check the label, though. Some commercially produced feta in the United States is made from cow’s milk, which eliminates this advantage.
Probiotics in Traditional Feta
Feta is a fermented food, and traditionally made versions can harbor beneficial bacteria. Lactobacillus plantarum, a well-studied probiotic strain, has been isolated from multiple feta cheese varieties as part of the natural bacterial community that develops during aging. Research on Greek feta found that lactic acid bacteria counts remained above 6 log CFU per gram throughout storage, meaning the beneficial microbes survive in meaningful numbers even as the cheese sits in brine for weeks.
Not all feta delivers this benefit equally. Mass-produced feta that has been pasteurized after production will have fewer live cultures than traditionally fermented versions. If probiotic content matters to you, look for artisanal or traditionally made feta, ideally from specialty stores or Mediterranean producers.
CLA: A Fatty Acid Worth Noting
Feta made from sheep and goat milk contains relatively high levels of conjugated linoleic acid, a naturally occurring fat that has been studied for its effects on body composition. Greek feta contains up to 1.9% CLA in its fat, with an average around 0.9%. Research in both animal and human studies has linked CLA to changes in the ratio of protein to fat in the body, though the effects in humans are modest. You wouldn’t eat feta specifically as a weight-loss tool, but it’s a small bonus that sets it apart from cheeses made with cow’s milk, which tend to have lower CLA levels.
Who Should Be Cautious
If you’re pregnant, the key rule is simple: only eat feta made with pasteurized milk. The CDC lists pasteurized feta as a safer food choice but warns against any cheese made from raw, unpasteurized milk due to the risk of Listeria infection. In the United States, most commercially sold feta is pasteurized, but imported varieties or farmers’ market products may not be. Check the label.
People who get migraines or take certain medications, particularly monoamine oxidase inhibitors, should know that aged feta can contain tyramine, a compound that triggers headaches and dangerous blood pressure spikes in sensitive individuals. Fresh feta is lower in tyramine than aged varieties, but Queensland Health guidelines list aged feta among cheeses to avoid for people on these medications. Small amounts may be tolerated, but it’s a real concern for this group.
How Much Feta to Eat
For most people, one to two ounces of feta per day fits comfortably into a healthy diet. That’s roughly a quarter cup of crumbled cheese, enough to top a salad or fill half a wrap. At that amount, you’re getting 8 grams of protein, nearly 280 milligrams of calcium, probiotics, and CLA for about 150 calories. The sodium will run 375 to 750 milligrams, so balance the rest of your meals accordingly.
Feta works especially well in Mediterranean-style eating patterns, where it’s paired with vegetables, olive oil, whole grains, and legumes. That context matters. A chunk of feta on a Greek salad with cucumbers, tomatoes, and olive oil is a different nutritional picture than feta melted onto processed bread with deli meat. The cheese itself is genuinely nutritious. What you eat it with determines whether the overall meal supports your health.
