Most cheeses contain very little carbohydrate (under 1 gram per ounce in hard and aged varieties) and produce minimal blood sugar rises. Cottage cheese and ricotta have slightly more carb but high protein blunts the rise. Pairing cheese with high-carb foods reduces the carb spike from the meal as a whole. Highly processed cheese spreads can have added starches and may have a larger effect.
Carb Content by Cheese Type
| Cheese | Serving | Carbs | Protein |
|---|---|---|---|
| Cheddar | 1 oz (28 g) | 0.4 g | 7 g |
| Parmesan | 1 oz | 0.9 g | 10 g |
| Swiss | 1 oz | 1.5 g | 8 g |
| Gouda | 1 oz | 0.6 g | 7 g |
| Mozzarella (whole milk) | 1 oz | 0.6 g | 6 g |
| Mozzarella (low moisture, part skim) | 1 oz | 1.0 g | 7 g |
| Brie | 1 oz | 0.1 g | 6 g |
| Feta | 1 oz | 1.2 g | 4 g |
| Cream cheese | 1 oz | 1.6 g | 2 g |
| Cottage cheese (low fat) | 1/2 cup | 4 g | 14 g |
| Ricotta (whole milk) | 1/2 cup | 4 g | 14 g |
| American (processed) | 1 oz | 2 g | 5 g |
| Cheese spread (Velveeta) | 1 oz | 3 g | 4 g |
Why Most Cheeses Are Low-Glycemic
- Aging breaks down lactose into lactic acid; older cheeses have minimal carb left
- Whey (the liquid carrying lactose) is removed during cheese-making
- Fat and protein content slow gastric emptying, reducing any glucose rise
- Even soft cheeses contain enough protein to blunt their own modest carb load
How Cheese Pairs With Carbs
| Pairing | Approximate Glucose Rise |
|---|---|
| 4 plain crackers (12 g carb) alone | 30 to 50 mg/dL |
| 4 crackers with 1 oz cheese | 15 to 30 mg/dL |
| 1 apple alone | 20 to 40 mg/dL |
| 1 apple with 1 oz cheese | 10 to 25 mg/dL |
| 2 slices bread alone | 40 to 70 mg/dL |
| Grilled cheese sandwich | 20 to 50 mg/dL |
Best Cheeses for Blood Sugar Management
- Aged cheddar — minimal carbs, satisfying flavor in small portions
- Parmesan — extremely low carb, easy to grate over salads
- Swiss — slightly higher carb but great protein
- Gouda and edam — low carb, good melting
- Manchego — Spanish hard sheep’s milk cheese, very low carb
- Mozzarella — versatile, low carb, low to moderate fat
- Feta — adds flavor with minimal carbs
- Cottage cheese — high protein, modest carb, excellent snack base
Cheeses to Watch
- Cheese spreads with added oil, starch, or sugar
- Velveeta and similar processed “cheese product”
- Squeeze-bottle cheese sauces
- Cheese-flavored crackers or chips (carbs from cracker, not cheese)
- Sweet flavored cream cheeses (strawberry, honey-walnut)
- Boursin with added fruit
How Cheese Fits Into a Diabetes-Friendly Diet
- 1 to 3 ounces daily fits most plans
- Pair with high-fiber crackers or whole-grain bread
- Add to salads for protein and satiety
- Use as a snack with nuts or olives
- Crumble over vegetables to make them more appealing
- Substitute for higher-carb dips and dressings
- Consider sodium and saturated fat in overall diet plan
Other Considerations
- Sodium: processed and aged cheeses can be high; rinse feta or choose low-sodium options if needed
- Saturated fat: moderate amounts are fine; balance with unsaturated fats elsewhere
- Lactose intolerance: hard aged cheeses are usually well tolerated
- Calcium: 200 to 250 mg per ounce in most cheese — supports bone health
- Probiotic varieties: Roquefort, gouda, brie may contribute helpful gut bacteria
Cheese Snack Ideas for Stable Blood Sugar
- 1 oz cheddar with 6 to 10 almonds
- 1/2 cup cottage cheese with 1/2 cup berries
- 2 string cheese sticks with celery
- Caprese salad: fresh mozzarella, tomato, basil, olive oil
- Greek salad with feta, cucumber, olives
- Hard-boiled egg with parmesan crisps
- Cheese cubes with sliced bell peppers
- Apple slices with brie
- Greek yogurt with crumbled feta and cucumber
- Whole-grain crackers (3 to 4) with sharp cheddar
What to Skip
- Cheesy pasta dishes with white sauce — high carb plus high fat
- Cheese-stuffed bread products
- Sweet dessert cheesecakes
- Nachos with cheese sauce — chip carbs, not cheese, drive the spike
- Cheese-and-fruit dessert combinations with high-sugar fruits or jams

The Bottom Line
Cheese, in most varieties, does not raise blood sugar significantly. Hard and aged cheeses contain under 1 gram of carb per ounce; even soft cheeses have modest carb content with high protein that blunts any rise. Cheese is a useful tool for blunting glucose spikes when paired with carb-rich foods. Best choices are cheddar, parmesan, mozzarella, gouda, brie, feta, and cottage cheese. Watch processed cheese spreads and “cheese product” formulations with added starches or sugars. Most people with diabetes can include 1 to 3 ounces of cheese daily as part of a glucose-friendly eating pattern.
