A Closer Look at the Composition of Swiss Cheese
Swiss cheese, a medium-hard, pale-yellow dairy product, is prized for its signature 'eyes' or holes and its mild, slightly nutty flavor. While American Swiss cheese is inspired by the traditional Emmental variety from Switzerland, the fundamental ingredients and fermentation process are similar. It is made from cow's milk, which is fermented using specific bacteria cultures. These cultures, including Propionibacterium freudenreichii, play a key role in breaking down lactose, producing carbon dioxide gas that forms the cheese's eyes, and contributing to its flavor profile. A nutritional analysis of what does Swiss cheese contain reveals a rich combination of macro and micronutrients.
Core Macronutrients in Swiss Cheese
Swiss cheese is a concentrated source of several key macronutrients, making it a filling and satisfying food option. For a standard one-ounce slice (approximately 28 grams), the nutritional content is notable.
- Protein: A single slice contains nearly 8 grams of high-quality, complete protein, which includes all nine essential amino acids. Protein is vital for building and repairing tissues, as well as for promoting feelings of fullness.
- Fats: With around 8 to 9 grams of total fat per ounce, Swiss cheese is not low-fat, although lower-fat varieties are available. It contains a notable amount of saturated fat, which should be considered in the context of your overall dietary intake.
- Carbohydrates: The fermentation process effectively breaks down most of the milk's lactose, resulting in a very low carbohydrate count, often less than 1 gram per serving.
Key Vitamins and Minerals
Beyond its macronutrient profile, Swiss cheese offers a surprising array of essential vitamins and minerals.
- Calcium: An excellent source, with one ounce providing approximately a quarter of the daily value for adults. This is crucial for bone health and proper muscle and nerve function.
- Phosphorus: This mineral works in tandem with calcium to build strong bones. A one-ounce serving offers a good percentage of the daily requirement.
- Vitamin B12: One of the most significant advantages of Swiss cheese is its high vitamin B12 content, which is important for energy production and a healthy nervous system. A single ounce can provide a substantial portion of your daily needs.
- Zinc: An essential mineral that supports the immune system and cell growth.
- Vitamin A: Important for vision, immune function, and skin health.
Low in Lactose
Due to its lengthy aging process, Swiss cheese contains very little lactose, with one slice having as little as 0.4 grams. This makes it a well-tolerated cheese for many individuals with lactose intolerance, although people with sensitivity should still pay attention to their overall serving size. The bacteria used in cheesemaking consume the lactose during fermentation and ripening, leaving behind the mild, nutty flavor.
Comparison of Swiss Cheese vs. Cheddar Cheese
To better appreciate what does Swiss cheese contain, it's helpful to compare its nutritional profile to another popular cheese, cheddar. The following table illustrates some key differences per 1-ounce slice.
| Nutrient | Swiss Cheese (approx.) | Cheddar Cheese (approx.) | Key Difference |
|---|---|---|---|
| Calories | 110 kcal | 115 kcal | Very similar calorie count. |
| Protein | 7.5 g | 6.5 g | Swiss cheese provides slightly more protein per ounce. |
| Fat | 9 g | 9.5 g | Cheddar has a marginally higher total fat content. |
| Saturated Fat | 5 g | 6 g | Cheddar is slightly higher in saturated fat. |
| Sodium | 52 mg | 180 mg | Swiss cheese is significantly lower in sodium. |
| Calcium | 25% DV | 20% DV | Swiss offers a higher percentage of the daily calcium value. |
| Vitamin B12 | 16% DV | 4% DV | Swiss cheese contains substantially more Vitamin B12. |
The Cheesemaking Process and Its Nutritional Impact
From the fresh milk to the finished wheel, the production of Swiss cheese is a multi-stage process that directly influences its final nutritional makeup.
- Milk Selection: The process begins with fresh cow's milk, which is filtered and tested for quality.
- Curdling: Lactic acid bacteria and rennet are added to the milk to cause it to curdle into a gelatinous mass.
- Cutting the Curd: A cheese harp is used to cut the curd into fine grains. The size of these grains determines the final cheese's texture; smaller grains lead to a harder cheese.
- Heating and Pressing: The curds are stirred and heated, which separates them from the whey. The curd is then pressed into molds to remove additional liquid.
- Brine Bath: The cheese wheels are submerged in a brine bath, where they absorb salt and form a protective rind. This step is intentionally milder for Swiss cheese, as the specific bacteria responsible for the eyes are salt-sensitive.
- Maturation: The cheese is matured in cellars, where bacteria produce carbon dioxide, forming the characteristic holes, and enzymes break down proteins and fats to develop the unique flavor. It is this aging period that leads to the low lactose content and nutty flavor.
Adding Swiss Cheese to a Healthy Diet
Incorporating Swiss cheese into your diet can be a delicious way to boost your intake of protein, calcium, and vitamin B12. Its low sodium content relative to many other cheeses also makes it a sensible option for those monitoring their salt intake. However, like all cheeses, it should be enjoyed in moderation due to its fat content. Try adding a slice to a sandwich, shredding it over a salad, or melting it into an omelet. The mild flavor makes it incredibly versatile.

Conclusion
From its foundational ingredients of cow's milk and bacterial cultures to its final form rich in protein, calcium, and B12, the answer to what does Swiss cheese contain is a surprisingly healthy and versatile profile. The unique fermentation process is key to its mild flavor, distinctive appearance, and low lactose content, making it a suitable choice for many. While its fat and sodium should be managed, adding a moderate amount of Swiss cheese to your meals can contribute positively to your nutritional goals.
