Yes, diabetics can eat cheese in moderation. Cheese has a very low glycemic index, is high in protein, and contains minimal carbohydrates — making it one of the more blood-sugar-friendly foods available. The key is choosing the right types and watching your portion size.
Why Cheese Works for Diabetics
Unlike many snack foods, cheese contains almost no carbohydrates. Most varieties have less than 1 gram of carbs per ounce, which means cheese itself has very little direct impact on blood sugar. Instead, cheese provides:
- High-quality protein (6-8 grams per ounce) that promotes satiety and steadies blood sugar
- Calcium for bone health — important since diabetes increases osteoporosis risk
- Vitamin B12 and phosphorus
- Probiotics in aged and fermented varieties that may benefit gut health
A study published in Diabetes Care found that increased consumption of yogurt and cheese was associated with a lower risk of developing type 2 diabetes, suggesting that certain dairy foods may have protective metabolic effects.
Best Cheeses for Diabetics
Cottage Cheese
Cottage cheese is arguably the best cheese for blood sugar management. A half-cup serving of low-fat cottage cheese provides about 14 grams of protein with only 5 grams of carbs and 2.5 grams of fat. Its high protein content makes it exceptionally filling. Pair it with vegetables, berries, or a sprinkle of cinnamon.
Ricotta (Part-Skim)
Part-skim ricotta offers a creamy, mild flavor with about 14 grams of protein per half cup. It works well as a spread on whole-grain toast, mixed into pasta dishes, or paired with fruit. Choose part-skim over whole-milk ricotta to reduce saturated fat.
Swiss Cheese
Swiss cheese has one of the best protein-to-fat ratios among hard cheeses. One ounce provides 8 grams of protein with 7 grams of fat. It is also naturally lower in sodium than most cheeses, making it a good choice for people watching both blood sugar and blood pressure.
Mozzarella (Part-Skim)
Part-skim mozzarella is lower in calories and fat than many other cheeses while still providing 7 grams of protein per ounce. Fresh mozzarella paired with tomatoes and basil (caprese salad) makes a simple, diabetes-friendly meal or snack.
Feta Cheese
Feta is naturally portion-controlled because of its strong flavor — a little goes a long way. It is lower in calories than most hard cheeses (75 calories per ounce) and adds savory depth to salads, omelets, and roasted vegetables.
Parmesan
Parmesan is one of the most protein-dense cheeses available (10 grams per ounce). Because of its intense, savory flavor, you need very little to add impact to dishes. A tablespoon of grated Parmesan on pasta, soups, or salads provides flavor with minimal calories.
Worst Cheeses for Diabetics
Processed Cheese (American Singles)
Processed cheese products contain added sodium, emulsifiers, preservatives, and sometimes added sugars. They are often labeled “cheese product” or “cheese food” rather than actual cheese. A single slice can contain 300-400 mg of sodium.
Cheese Spreads and Dips
Jarred cheese dips, spray cheese, and cheese spreads typically contain added starches, sugars, oils, and artificial ingredients. They are also easy to over-consume because they do not provide the same satiety signals as real cheese.
Heavily Flavored Cheese
Cheese coated in fruit, nuts mixed with sweeteners, or flavored with honey or cranberries can add hidden sugars. Check the ingredient list — if sugar or sweeteners appear in the first few ingredients, choose a different option.

Portion Sizes for Diabetics
Even though cheese is low in carbs, calories and saturated fat can add up quickly. Here are practical portion guidelines:
- Hard cheese (cheddar, Swiss, Parmesan): 1-1.5 ounces (about the size of 3-4 dice or your thumb)
- Soft cheese (cottage, ricotta): 1/3 to 1/2 cup
- Shredded cheese: 2-3 tablespoons
- Sliced cheese: 1-2 slices
A food scale can be helpful when you are first learning what these portions look like. Over time, you will develop an eye for appropriate serving sizes.
Smart Ways to Include Cheese in a Diabetic Diet
Cheese works best when paired with fiber-rich foods. Here are balanced ways to enjoy it:
- Cottage cheese + sliced cucumber + everything bagel seasoning — a high-protein, low-carb snack
- Mozzarella + tomato + basil (caprese) — pair with a drizzle of olive oil and balsamic
- Swiss cheese + turkey + whole grain mustard roll-up — skip the bread for a low-carb option
- Parmesan + roasted vegetables — adds savory flavor to broccoli, cauliflower, or zucchini
- Feta + spinach salad + chickpeas — a complete meal with protein, fiber, and healthy fats
- String cheese + a small apple — the classic protein-plus-fruit pairing

Cheese and Heart Health Considerations
People with diabetes are at higher risk for cardiovascular disease, which raises questions about cheese’s saturated fat content. The picture is more nuanced than “saturated fat is bad”:
- Observational studies have generally found that moderate cheese consumption (1-2 servings per day) is not associated with increased cardiovascular risk
- The “food matrix” of cheese — its combination of calcium, protein, and fermentation products — may offset some of the negative effects of saturated fat
- Fermented dairy products (aged cheese, yogurt) may have different cardiovascular effects than non-fermented dairy
That said, if you have high cholesterol or established heart disease, discuss dairy intake with your doctor. Choosing lower-fat options (part-skim mozzarella, low-fat cottage cheese, reduced-fat Swiss) is a reasonable approach for those who need to limit saturated fat.

The Bottom Line
Cheese is a diabetes-friendly food when consumed in moderation. Its low glycemic index, high protein content, and minimal carbohydrates make it a strong choice for snacks and meals. Stick to real, minimally processed cheeses — cottage cheese, mozzarella, Swiss, feta, and Parmesan are among the best options. Avoid processed cheese products with added sodium and fillers. Keep portions to 1-1.5 ounces of hard cheese or about 1/2 cup of soft cheese, and pair with vegetables or whole grains for a balanced, blood-sugar-friendly eating pattern.
