How many carbs are in an American slice of cheese?

Cheese is a beloved ingredient and food for many people. Its rich, creamy, salty, and umami flavors make it a tasty addition to sandwiches, burgers, pizzas, pastas, appetizers, and more. While cheese can be high in fat and sodium, many varieties are also excellent sources of protein, calcium, and other important nutrients.

When following a low-carb or keto diet, cheese can seem like an ideal food. However, the carb counts in different types of cheese can vary. So, how many carbs are in an American slice of cheese?

What are American Cheese Slices?

American cheese slices refer to processed cheese products made from a blend of milk, milk proteins, whey, milkfat, salts, and food coloring. The cheese is produced by combining the ingredients into an emulsion. It is then poured into molds, cooled, and cut into individual slices.

Some key features of American cheese slices include:

  • Soft, creamy, and melty texture
  • Mild, tangy, salty flavor
  • Bright orange color from added annatto food coloring
  • Sold in thin, uniformly cut slices
  • Common brands include Kraft, Sargento, and Land O’Lakes
  • Used often for sandwiches, burgers, grilled cheese, and snacking

American cheese differs from natural cheeses in that it is processed and homogenized. The FDA defines American cheese as a processed cheese product made from at least two types of actual cheese. However, most American cheese slices also contain milk products, emulsifiers, preservatives, and stabilizers.

Nutrition Information in American Cheese Slices

The nutrition content of American cheese can vary slightly between brands. But in general, a 1-ounce slice (about 1 single slice) contains approximately:

  • Calories: 90
  • Total fat: 7g
  • Saturated fat: 4.5g
  • Cholesterol: 25mg
  • Sodium: 330mg
  • Total carbs: 1g
  • Dietary fiber: 0g
  • Sugars: 1g
  • Protein: 6g
  • Calcium: 200mg

As you can see, a single slice of American cheese is high in fat, sodium, and cholesterol compared to other cheese varieties. It also provides calcium and protein.

Importantly, an American cheese slice contains just 1 gram of total carbohydrates. This makes it a low-carb friendly choice for restricted carb eating patterns like the keto diet.

Carb Count of American Cheese vs. Other Cheeses

How does American cheese compare to other popular cheese choices in terms of carbs? Here is an overview:

Cheddar Cheese

A 1-ounce serving of cheddar cheese provides about 0.4 grams of carbs. So cheddar contains fewer carbs than American cheese slices. However, cheddar is also higher in fat and calories than American cheese.

Mozzarella Cheese

With about 1.4 grams of carbs per ounce, fresh mozzarella offers slightly more carbs than American or cheddar cheese. Part-skim, low-moisture mozzarella sticks are lower in carbs with about 0.7 grams per ounce.

Swiss Cheese

With 0.5 grams of carbs per ounce, Swiss cheese is very low-carb. And it contains fewer carbs than either American cheese or regular mozzarella.

Blue Cheese

Crumbly and flavorful blue cheese clocks in at just 0.3 grams of carbs per ounce. So it’s one of the lowest carb cheese options.

Parmesan Cheese

Hard, salty parmesan cheese contains only 0.9 grams of carbs per ounce. Freshly grated parmesan has such little carbs that most labels even list it as 0g per serving.

Cream Cheese

Soft cream cheese is higher in carbs with about 1.6 grams per ounce. Whipped cream cheese tends to be lower with 0.8 grams per ounce.

How Slice Size Impacts Carb Content

When calculating the carbs in American cheese, the slice size matters. Here’s how the carb count changes based on slice size:

  • 1 regular slice (1 ounce): 1g carbs
  • 1 thick slice (1.5 ounces): 1.5g carbs
  • 1 jumbo slice (2 ounces): 2g carbs

As you can see, thicker slices contain more total carbs. However, the carb density remains the same at 1 gram of carbs per 1 ounce of American cheese.

Carb Differences in Types of American Cheese

There are a few varieties of American cheese that have slight differences in their nutrition profiles:

Regular American Cheese Slices

The standard type of American cheese described earlier provides 1g carb per ounce.

2% Milk American Cheese

Sargento and some other brands make 2% milk American cheese. The lower fat content means this type contains about 0.7 grams of carbs per ounce.

Fat-Free American Cheese

You can also find fat-free, low-calorie American cheese. Kraft Fat Free Singles have <1 gram of carbs per slice. However, the taste and texture aren’t as creamy.

Organic American Cheese

Organic brands like Organic Valley make American cheese with organic milk and no artificial colors or preservatives. The carb count is the same as regular American cheese.

Carbs in American Cheese Slices vs. Blocks

American cheese is available both sliced and in solid blocks. Here’s the carb difference:

  • Sliced cheese: 1g carbs per ounce
  • Block cheese: 0.7g carbs per ounce

So in block form, American cheese is slightly lower in carbs, providing about 0.3g less per ounce. This minor difference is likely due to the manufacturing process of slicing.

Calories in American Cheese

In addition to looking at carbs, it’s helpful to know the calorie density of American cheese:

  • 1 regular slice (1 ounce): 90 calories
  • 1 thick slice (1.5 ounces): 135 calories
  • 1 jumbo slice (2 ounces): 180 calories
  • 1-ounce block: 80 calories

As expected, thinner slices contain fewer calories than thicker cut slices in a comparable serving size. Block American cheese is a bit lower in calories than sliced.

Is American Cheese Keto-Friendly?

The keto diet aims to get 70-80% of total daily calories from fat, 15-20% from protein, and just 5-10% from carbs. This ultra low-carb eating pattern can promote fat loss.

With just 1 gram of net carbs and 7g of fat per slice, American cheese can fit into a keto diet. However, some keto dieters may still prefer other cheese options for less processed options with more beneficial fats.

Here are some tips for fitting American cheese into a keto eating pattern:

  • Count 1g net carbs per ounce of American cheese
  • Measure portions carefully, as slices vary in size
  • Limit to 1-2 slices per day to keep carb intake low
  • Pair it with high-fat add-ons like bacon or avocado
  • Choose block cheese over sliced for slightly fewer carbs
