Feta cheese is a diabetes-friendly cheese with about 1 g carbohydrate, 4 g protein, 6 g fat, and 75 calories per 1-oz serving. The glycemic impact is essentially zero. Authentic Greek feta (a Protected Designation of Origin product) is made from sheep’s milk or a combination of sheep’s milk and up to 30% goat’s milk, aged in brine for at least 2 months. The tangy, salty flavor and crumbly texture distinguish it. Outside the EU, “feta-style” cheeses may be made from cow’s milk with softer texture and milder flavor. For diabetes, all varieties have similar nutritional profiles. The main consideration is sodium — feta is brined and contains 300-400 mg per oz, requiring moderation for adults on sodium-restricted diets. Feta pairs naturally with Mediterranean diabetes-friendly foods — tomatoes, cucumbers, olives, peppers, fresh herbs (oregano, mint, dill, basil). Applications include Greek salad, spinach-feta omelet, roasted vegetables with crumbled feta, watermelon-feta salad with mint, stuffed peppers, and grain bowls.

Sodium Reduction Strategies
- Limit to ½-1 oz per serving.
- Drain and pat dry before serving.
- Brief rinse under cold water to reduce surface sodium.
- Pair with naturally low-sodium foods (fresh vegetables, herbs).
- Choose lower-sodium “lite” feta when available (~200 mg per oz).
- For adults on sodium-restricted diets, plan feta as occasional treat.
- Skip additional salt in feta-containing dishes.
Buying and Storage
- Choose authentic Greek feta (PDO label) or specify sheep/goat milk for richer flavor.
- Block feta in brine: typically 2-3 weeks refrigerator life after opening.
- Pre-crumbled feta: convenient; slightly higher cost.
- Store block feta in brine in refrigerator; submerged in liquid.
- Wrap individual portions in plastic if not in brine.
- Pre-crumbled feta in cellulose-coated form lasts 1-2 weeks.
- Freezing changes texture — not recommended.
Who Should Be Careful
- Adults on sodium-restricted diets (heart failure, hypertension, CKD).
- Adults watching saturated fat intake closely.
- Pregnant women should ensure feta is pasteurized (some imported versions may not be).
- Adults with severe lactose intolerance — feta has some lactose; check tolerance.
- Adults with milk protein allergy.
- Most adults with type 2 diabetes can include feta in moderate portions.
The Bottom Line
Feta cheese is a diabetes-friendly cheese with about 1 g carbohydrate, 4 g protein, 6 g fat, and 75 calories per 1-oz serving. The glycemic impact is essentially zero. Authentic Greek feta is made from sheep’s milk or sheep-goat milk blend; “feta-style” cheeses outside the EU may be cow’s milk. All varieties have similar nutritional profiles for diabetes purposes. Main consideration is sodium — feta is brined and contains 300-400 mg per oz, requiring moderation for adults on sodium-restricted diets. Strategies: limit to ½-1 oz per serving, drain and pat dry before serving, brief rinse to reduce surface sodium, pair with low-sodium foods, or choose lower-sodium “lite” varieties. Feta pairs naturally with Mediterranean diabetes-friendly foods — tomatoes, cucumbers, olives, peppers, fresh herbs (oregano, mint, dill, basil). Practical applications include Greek salad, spinach-feta omelet, roasted vegetables with crumbled feta, stuffed peppers, watermelon-feta salad with mint, grain bowls, and Mediterranean lettuce wraps. The crumbly texture and tangy flavor add satisfaction to dishes without significant carbohydrate impact. Most adults with type 2 diabetes can include feta as part of a Mediterranean-style eating pattern. See our broader diabetes diet guide for context.
