The Basic Building Blocks of Cheddar
At its core, Cheddar cheese is a natural dairy product made primarily from four simple ingredients: milk, salt, a bacterial culture, and an enzyme called rennet. The process involves curdling the milk, separating the liquid whey, and then using the unique 'cheddaring' technique, which involves stacking and flipping the curds to press out additional moisture. This process, followed by aging, is what gives Cheddar its characteristic texture and flavor, which can range from mild to extra sharp over time.
Macronutrients: Fuel and Energy
Cheddar is an energy-dense food, with a typical 1-ounce (28g) serving containing around 114 to 120 calories. This energy is supplied by its concentrated macronutrient profile:
- Protein: A 1-ounce serving provides approximately 6.5 to 7 grams of high-quality, complete protein, which is vital for muscle repair, growth, and overall bodily function. Because it contains all nine essential amino acids, it's considered a complete protein source.
- Fat: This is Cheddar’s dominant macronutrient, with about 9 to 10 grams per ounce. The majority of this fat is saturated fat (around 5 to 6 grams per ounce). While historically viewed negatively, recent studies suggest that the complex “cheese matrix” may alter how the body processes these fats, potentially having a more neutral effect on cholesterol than previously thought.
- Carbohydrates: Cheddar cheese is naturally very low in carbohydrates, containing less than one gram per ounce. This makes it a popular option for those on low-carb diets, such as the ketogenic diet. The aging process further reduces the lactose content, making it generally easier to digest for individuals with lactose intolerance.
Micronutrients: A Wealth of Vitamins and Minerals
Beyond its macronutrient content, Cheddar is a rich source of many crucial micronutrients.
Key Vitamins
- Vitamin B12: An essential vitamin for red blood cell formation, nerve function, and DNA synthesis. Cheddar provides a good source, with some varieties offering up to 13% of the Daily Value per 1-ounce serving.
- Vitamin A: Important for healthy vision, immune function, and skin health. Cheddar is a notable source of vitamin A.
- Vitamin K2: Found primarily in animal products and fermented foods, vitamin K2 helps regulate where calcium is deposited in the body, which is important for both bone and heart health. Aged hard cheeses like Cheddar are excellent sources of this nutrient.
- Riboflavin (B2): Plays a critical role in energy production and cellular function. Cheddar contains a significant amount of riboflavin.
Essential Minerals
- Calcium: A powerhouse for bone and dental health, calcium is abundant in Cheddar. A 1-ounce serving provides around 15-20% of the recommended daily intake.
- Phosphorus: Working with calcium, phosphorus is crucial for building strong bones and teeth. A serving of Cheddar offers a solid contribution to daily phosphorus needs.
- Zinc: An important mineral for immune system function and metabolism. Cheddar contains a moderate amount of zinc.
- Selenium: This trace mineral is a potent antioxidant and supports thyroid function. Aged Cheddar is a particularly good source of selenium.
Probiotic Potential
While many people associate probiotics with yogurt, some aged cheeses, including Cheddar, can contain live probiotic bacteria. Studies have shown that certain probiotic strains can survive the cheese-making process and aging, and these bacteria may also survive the digestive process, potentially contributing to a healthier gut microbiome. When choosing a probiotic-rich cheese, look for labels indicating 'live' or 'active cultures.'
Comparing Cheddar to Other Cheeses
Here is a comparison of the nutritional content of a 1-ounce (28g) serving of several popular types of cheese. Note that figures can vary by brand and aging process.
| Nutrient | Cheddar Cheese | Swiss Cheese | Mozzarella Cheese |
|---|---|---|---|
| Calories | ~115 | ~106 | ~85 |
| Protein | ~7g | ~8g | ~6g |
| Fat | ~9g | ~8g | ~6g |
| Saturated Fat | ~5g | ~5g | ~4g |
| Sodium | ~183mg | ~54mg | ~170mg |
| Calcium | ~191mg | ~200mg | ~200mg |
Navigating the Nutritional Caveats
While Cheddar offers significant nutritional benefits, it's important to consume it in moderation, as it is relatively high in calories, saturated fat, and sodium. For those with dietary restrictions or health conditions like high blood pressure or heart concerns, paying attention to portion size is key. Choosing sharp or extra-sharp varieties can be beneficial, as their more intense flavor allows for a satisfying experience with a smaller portion. Some research even suggests that the cheese matrix can have a more benign effect on cholesterol than saturated fat alone, but moderation remains essential.

Conclusion
Cheddar cheese is a complex food with a nutritional profile that extends well beyond its delicious taste. It is an excellent source of high-quality protein and a rich depot of bone-strengthening calcium and phosphorus, as well as essential vitamins like B12, A, and K2. While containing significant amounts of saturated fat and sodium, these components can be managed through mindful portion control. For a gut-friendly bonus, some aged Cheddar varieties may even contain beneficial probiotics. By understanding what Cheddar cheese contains, you can appreciate its nutritional contributions while fitting it smartly into a balanced diet.
