Feta cheese is a nutritious option that fits well into a balanced diet. At about 75 calories per ounce, it’s lower in calories and fat than most popular cheeses while delivering a solid hit of protein, calcium, and beneficial bacteria. The main trade-off is sodium, which runs higher than many other cheeses, but there are easy ways to manage that.
Nutrition in a One-Ounce Serving
A single ounce of feta (roughly the size of a pair of dice) contains about 75 calories, 4 grams of protein, and 6 grams of fat, of which about 4 grams are saturated. That calorie count is noticeably lower than cheddar (around 113 calories per ounce) or brie, making feta a good choice when you want flavor without a heavy caloric load. Its crumbly texture also helps with portion control. A little feta scattered over a salad or grain bowl goes a long way in taste compared to a thick slice of cheddar or gouda.
On the micronutrient side, feta provides calcium and phosphorus, both important for bone strength, along with B vitamins. Traditional feta is made from sheep’s milk or a blend of sheep and goat milk, which tends to carry more of certain minerals than cow’s milk cheese.
How Feta Compares on Sodium
Sodium is feta’s biggest nutritional downside. One ounce contains roughly 260 mg, which is about 11% of the commonly recommended daily limit of 2,300 mg. That’s higher than cheddar (185 mg), mozzarella (178 mg), and Swiss (53 mg), though it’s actually lower than several cheeses people don’t typically worry about, like parmesan (390 mg), blue cheese (325 mg), and processed American cheese (468 mg).
If you’re watching your sodium intake, rinsing feta under water for a few seconds before eating it can wash away a meaningful amount of surface salt. Soaking it in fresh water for 15 to 30 minutes pulls out even more. Since feta is stored in brine (salt water), this simple step makes a real difference without ruining the flavor.
Gut-Friendly Bacteria
Because feta is brined rather than heavily heated or pressed, it can harbor live bacterial cultures that function as probiotics. Researchers have isolated several beneficial strains from traditional feta, including varieties of Lactobacillus that are known to support gut health. These bacteria survive the brining and cold storage process, meaning they’re still alive when you eat the cheese.
Not all store-bought feta will contain meaningful levels of live cultures. Highly processed versions or those made with pasteurized milk and no added cultures may have fewer beneficial organisms. If probiotic content matters to you, look for traditionally made feta or brands that specifically mention live cultures on the label.
Easier to Digest Than Many Cheeses
Feta is surprisingly friendly for people with lactose sensitivity. The brining and aging process breaks down most of the lactose, leaving just 0.13 grams per serving, according to Monash University’s FODMAP research. That’s classified as low-lactose, and most people with lactose intolerance can eat it without symptoms. For comparison, a glass of milk contains about 12 grams of lactose.
Traditional feta made from sheep or goat milk may offer another digestibility advantage. These milks naturally contain a protein structure (A2 beta-casein) that some people find easier on their stomachs than the A1 protein dominant in conventional cow’s milk. If regular cheese leaves you feeling bloated, sheep’s milk feta is worth trying.
Conjugated Linoleic Acid
Feta contains conjugated linoleic acid (CLA), a naturally occurring fat that has drawn interest for its potential role in metabolism and inflammation. CLA levels in feta actually increase during the ripening process, reaching about 0.75 grams per 100 grams of fat, before gradually declining during longer storage. This means fresher feta that has been properly aged (but not stored for months) tends to have higher CLA levels.
CLA is found in other dairy products and grass-fed meat as well. While animal and lab studies have linked it to improvements in body composition and inflammation, the amounts you’d get from feta alone are modest. It’s a nice bonus of eating feta, not a reason to eat it in large quantities.
Who Should Be Cautious
Feta is classified as a high-tyramine food because of its brining and aging process. Tyramine is a compound that forms as proteins break down, and it can cause dangerous blood pressure spikes in people taking a class of antidepressants called MAOIs. The Mayo Clinic specifically lists feta among cheeses that people on MAOIs should avoid. Tyramine levels vary between brands and batches, so there’s no reliably safe amount for this group.
During pregnancy, the key distinction is pasteurization. Feta made from pasteurized milk is considered a safer choice by the CDC. Unpasteurized (raw milk) feta carries a risk of Listeria contamination, which can cause serious complications during pregnancy. In the United States, most commercially sold feta is pasteurized, but it’s worth checking the label, especially with imported or artisan varieties.
How Feta Fits Into a Healthy Diet
Feta works best as a flavor enhancer rather than a main protein source. A one-ounce crumble on a salad, roasted vegetables, or whole grain dish adds tang and saltiness that can reduce the need for dressings or added salt. Because feta has such a strong flavor, you naturally use less of it than milder cheeses, which keeps calories and saturated fat in check.
Pairing feta with potassium-rich foods like tomatoes, cucumbers, spinach, and watermelon (classic Mediterranean combinations, as it turns out) helps offset the sodium. The Mediterranean diet, which features feta regularly, is one of the most studied dietary patterns for heart health and longevity. In that context, moderate feta consumption is part of a pattern linked to lower rates of heart disease, not higher ones.
For most people, one to two ounces of feta a day fits comfortably within a healthy eating pattern. If you have high blood pressure or are on a sodium-restricted diet, staying toward the lower end and rinsing the cheese before eating makes feta a reasonable indulgence rather than something to avoid entirely.
