Does Cheese Have Sugar? Facts

Most cheeses contain very little sugar, and many contain none at all. Sugar in cheese comes almost entirely from lactose, the natural sugar found in milk. During cheesemaking, most of the lactose drains away with the whey or gets converted into lactic acid by bacteria. A hard cheddar cheese typically has less than 0.5 grams of sugar per serving, while some fresh cheeses like ricotta may have a few grams. The only cheeses with significant added sugar are flavored or processed products, so reading the label matters more than the type of cheese.

Why Is There Sugar in Cheese?

All milk contains lactose. Lactose is a disaccharide — a sugar made of two smaller sugar molecules, glucose and galactose. When milk is turned into cheese, bacteria eat that lactose and turn it into lactic acid. This process is what gives cheese its tangy flavor.

The amount of lactose left behind depends on how the cheese is made and how long it ages. Fresh cheeses spend less time fermenting, so they keep more lactose. Aged cheeses have more time for bacteria to consume the sugar, so they end up with almost none.

Most of the lactose also leaves in the whey. Whey is the liquid part of milk that separates from the curds during cheesemaking. Since lactose dissolves in water, much of it drains away before the cheese is even formed.

Does Cheese Have Sugar? Checking the Nutrition Label

On a nutrition facts label, “total sugars” includes both naturally occurring and added sugars. For plain cheese, the sugar listed is lactose. It is not table sugar.

Here is what you typically find in a standard serving of common cheeses:

These figures come from USDA food composition data. The exact numbers vary slightly by brand and recipe, but the pattern holds. Hard aged cheeses have almost no sugar. Soft fresh cheeses have more.

Which Cheeses Have the Most Sugar?

Fresh cheeses retain the most lactose. Ricotta, cottage cheese, and mascarpone sit at the higher end for natural cheese. Cream cheese also contains a small amount — usually less than 1 gram per tablespoon.

Processed cheese products are the real concern. Cheese spreads, cheese sauces, and individually wrapped American cheese slices often contain added milk solids, whey powder, or sugar to improve texture and flavor. Some flavored cheeses — like smoked, honey, or fruit varieties — may have added sugar too.

Check the ingredient list. If you see sugar, corn syrup, or honey listed, the product has added sugar. Plain cheese should list only milk, culture, rennet, and salt.

Can People with Lactose Intolerance Eat Cheese?

Many people with lactose intolerance can eat aged cheese without symptoms. Hard cheeses like cheddar, Swiss, and Parmesan contain so little lactose that they are often well tolerated.

Lactose intolerance happens when the body does not make enough lactase, the enzyme that breaks down lactose. Undigested lactose travels to the colon, where bacteria ferment it. That fermentation causes gas, bloating, and diarrhea.

The amount of lactose a person can tolerate varies widely. Some people react to even small amounts. Others can handle a few grams. There is no universal threshold that works for everyone.

If you are lactose intolerant, start with a small portion of aged cheese and see how your body responds. Fresh cheeses like ricotta and cottage cheese are more likely to cause problems because they contain more lactose.

Lactose-free cheeses exist but are less common. Some brands add lactase enzyme to break down the lactose during production, leaving a cheese that tastes slightly sweeter because the lactose has been split into glucose and galactose.

Is the Sugar in Cheese a Problem for Blood Sugar?

For most people, no. The amount of lactose in a normal serving of cheese is tiny. Cheese is also high in protein and fat, which slow digestion and blunt any rise in blood sugar.

Cheese has a very low glycemic index. The glycemic index measures how quickly a food raises blood glucose. Foods with fat and protein, like cheese, score low because they empty slowly from the stomach.

People with diabetes can usually eat cheese without issue. The American Diabetes Association does not restrict cheese. The concern is portion size and calories, not sugar content.

One exception: processed cheese products with added sugar. These can contain several grams of sugar per serving, and some flavored spreads contain more. If you are watching carbohydrate intake, read the label and treat these like any other processed food.

What About Cheese and Cavities?

Cheese is actually considered protective for teeth. Research has found that eating cheese increases saliva production, which helps wash away food particles and neutralize acid in the mouth.

Some studies suggest that compounds in cheese may help remineralize tooth enamel. The calcium and phosphate in cheese can support this process. This is the opposite of what sugary foods do.

The concern would be cheese products with added sugar. A sweet cheese spread or dessert cheese behaves more like candy than cheese when it comes to dental health.

Does Cheese Have Sugar If It Is Organic or Grass-Fed?

The sugar content does not change based on organic certification or grass-fed labeling. Lactose is a natural component of milk. Cows that eat grass produce milk with the same lactose structure as cows that eat grain.

Organic and grass-fed cheeses may differ in fat composition and some micronutrients, but sugar content stays essentially the same. If a grass-fed cheese label claims to be sugar-free, that claim is about lactose, not added sweeteners.

How to Tell If Your Cheese Has Added Sugar

The nutrition label is your best tool. Look at the “Total Sugars” line. Then look at the ingredient list.

If the only ingredients are milk, culture, rennet, and salt, the sugar on the label is lactose. It is naturally occurring and present in small amounts.

If you see any form of sweetener — sugar, cane syrup, honey, fruit concentrate — the cheese has added sugar. The amount will be listed under “Includes Added Sugars” on newer labels.

Some cheese products label themselves as “sugar-free.” For hard aged cheese, this is technically true because the lactose content rounds to zero on the label. For processed cheese, sugar-free claims should be verified by reading the full ingredient list.

Cheese Alternatives and Sugar

Vegan cheese alternatives are a separate category. These products are made from nuts, coconut oil, soy, or starch, not milk. They contain no lactose.

However, vegan cheeses often contain added sugar or starches to improve taste and texture. Some brands add sugar to mimic the sweetness of dairy. Others rely on modified food starch, which is a carbohydrate but not listed as sugar.

Nutritional yeast, sometimes used to make vegan cheese sauce, contains no sugar. But commercial vegan cheese sauces frequently do. Read labels carefully — “no dairy” does not mean “no sugar.”
