Cheese is a great source of protein, with some varieties containing more protein than others. The protein content in cheese is influenced by its texture, with harder cheeses like Swiss or cheddar having higher protein content than softer ones like Brie or Camembert. The type of milk used also affects the protein content, with lower-fat milk resulting in a higher protein-to-fat ratio. For example, skim milk ricotta contains around 14 grams of protein per serving, while whole-milk ricotta has only 9 to 10 grams. Cottage cheese, known for its high protein content, is often recommended for weight loss due to its ability to increase feelings of fullness and reduce calorie intake. Other high-protein cheeses include Parmesan, Romano, Gruyere, low-fat Swiss, and Fontina.

What You'll Learn
Harder cheeses have higher protein content
Cheese is a great source of high-quality protein. It contains the two primary types of protein found in milk: casein, which accounts for about 80% of the total protein content, and whey, which is responsible for the remaining 20%. Both of these are considered complete proteins, as they contain all nine essential amino acids.
However, not all cheeses are created equal when it comes to protein content. Harder cheeses, such as Swiss or cheddar, tend to have higher protein content than softer cheeses like Brie or Camembert. This is because firmer cheeses hold less water, resulting in a higher proportion of protein in a smaller package. The process of cheesemaking involves concentrating the solids originally present in milk, and since protein is one of the main constituents of these solids, a higher concentration leads to a higher protein content in the final product.
For example, an ounce of cheddar cheese typically contains about eight grams of protein, while an ounce of Brie has around six grams. Parmesan, a hard, aged cheese, is another excellent source of protein. Its long aging process converts lactose into lactic acid, resulting in a very low lactose content, making it suitable for individuals with lactose intolerance.
Other high-protein cheeses include cottage cheese, low-fat Swiss, ricotta, and Gruyère. In general, cheeses that are lower in fat tend to have higher protein content. For instance, skim milk ricotta contains around 14 grams of protein per serving, while whole milk ricotta contains about 9-10 grams.

Whey protein in cheese
Cheese is a great source of protein, and different types of cheeses have different amounts of protein. For example, harder cheeses like Swiss or cheddar tend to have more protein than softer ones like brie or Camembert. This is because harder cheeses have a higher proportion of protein as they hold less water.
Cheese contains the two primary types of protein found in milk: casein protein, which accounts for about 80% of the total protein content, and whey protein, which makes up the other 20%. Whey is a byproduct of the cheese-making process, created when rennet or an edible acid is added to heated milk, causing it to coagulate or curdle and separate into milk solids (curds) and liquid whey. While historically whey was considered a waste product, it has since been recognised to have many uses and health benefits.
Whey is used to produce whey cheeses such as ricotta, brunost, and whey butter, and is also added to many other products, including processed foods like breads and crackers, health foods, and animal feed. The protein in ricotta cheese is mostly whey, and it is easily absorbed by the body. Whey is particularly high in the essential amino acids that humans need to get from food, and it has been found to promote muscle growth, lower blood pressure, and reduce high cholesterol levels.
The amount of whey in the finished cheese product varies depending on the type of cheese. Cottage cheese, ricotta cheese, and similar types have the largest amount of whey, while very hard cheeses like Parmesan have very little. This residual whey contributes to the total protein content of the cheese, as well as its nutritional value, including its sugar (lactose) content.

Casein protein in cheese
Cheese is a rich source of protein, and contains the two primary types found in milk: casein protein and whey protein. Casein accounts for about 80% of the total protein content in cheese, while whey makes up the remaining 20%. Casein proteins are a group of four different types of protein that are naturally present in animal milk, including cow, human, goat, and buffalo milk.
Casein proteins play a crucial role in the process of making cheese. In milk, casein proteins exist as micelles, which are small (50-500 nm) structures that reflect light, making milk appear white. When making cheese, the addition of acid or rennet causes the casein proteins to clump together and form curds, which are used to make cheese. The curds are formed when the enzymes in rennet break down the κ-casein proteins, causing them to curdle and create large curd structures. The curds are then used to make cheese, with the remaining liquid becoming translucent due to the absence of casein micelles.
The amount of casein in cheese can vary slightly depending on the type of cheese. For example, goat cheese has less alpha-S1 casein than other cheeses because goat's milk contains primarily alpha-S2 casein. However, the overall casein content remains relatively consistent across different types of cheese. The texture of cheese can also be influenced by the amount of casein it contains. Generally, harder cheeses like Swiss or cheddar tend to have higher protein content than softer cheeses like Brie or Camembert due to their lower moisture content.
Cheese is a fundamental dairy product that not only provides protein but also delivers several micronutrients, including calcium, phosphorus, and potassium. The presence of casein proteins in cheese contributes to its structure, texture, and overall nutritional profile, making it a versatile and beneficial food item.

High-protein cheeses
Cheese is a great source of high-quality protein. The current Recommended Dietary Allowance (RDA) for protein is 0.8 grams (g) per kilogram (kg) of body weight daily. However, research suggests that the protein intake should be between 1.2-2 g per kg of body weight daily.
- Cottage cheese, which is much higher in protein than other cheeses. It is also lower in calories than other types of cheese.
- Mozzarella, which has 6.9 g of protein per ounce or 9.6 g per 100 calories. It is also lower in sodium and saturated fat than other cheeses.
- Ricotta, which is made from the watery parts of the milk of cows, goats, sheep, or Italian water buffalo that are left over from making other cheeses. It is a good source of whey protein, which contains all the essential amino acids.
- Blue cheese, which has 6.1 g of protein per ounce and 100 calories.
- Feta, which has approximately 4 g of protein per ounce or 5.4 g per 100 calories.
- Brie, which has 5.9 g of protein per ounce or 6.2 g per 100 calories.
- Parmesan, which is a hard, aged cheese with a gritty texture and a salty, nutty flavor. It is made from raw, unpasteurized cow’s milk that is aged for at least 12 months. It is also one of the highest protein cheeses.
- Cheddar, which is a staple in many households due to its rich taste and easy accessibility.

Low-protein cheeses
While cheese is a good source of protein, some varieties are lower in protein than others. For example, cream cheese has about two grams of protein per ounce, while brie has about six grams per ounce. Generally, harder cheeses like Swiss or cheddar tend to be higher in protein than softer ones like brie and Camembert. This is because harder cheeses have a lower moisture content, so the nutrients are more densely packed.
For those seeking low-protein cheese options, vegan cheese is often recommended as it is not derived from dairy, which is a primary source of protein in cheese. However, it is important to note that some vegan cheeses may still contain protein, with some brands containing up to three grams of protein per ounce. Additionally, they can be challenging to find and may not always taste the same as dairy cheeses.
Another option for reducing protein intake from cheese is to use cheese powders or oil-based extracts, which can be added to dishes like soups or popcorn. These products can provide the flavour of cheese without the protein content. However, it is important to read the labels carefully as some of these products may still contain small amounts of protein.
It is worth noting that the current Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight daily. However, some research suggests that a higher protein intake of 1.2-2 grams per kg of body weight may be beneficial.
