Protein Content: A Closer Look
When comparing the protein content of peanut butter and cheddar cheese, it's crucial to look at two different metrics: the protein amount per standard serving and the protein density per calorie. While both foods are valued for their protein, the context of their consumption reveals different winners depending on your dietary focus.
Per 100 Grams: A Comprehensive Comparison
For a direct, standardized comparison, looking at 100-gram measurements removes the bias of different serving sizes. A 100-gram portion of cheddar cheese and peanut butter provide surprisingly similar amounts of protein, though some data shows a slight edge to cheese. The key difference lies in what else comes with that protein. Per 100g, peanut butter is much higher in total fat and calories, while cheddar cheese contains a significant amount of saturated fat and sodium.
Per Standard Serving: A Practical Perspective
For most people, a typical serving size is more relevant. A standard serving of peanut butter is about two tablespoons, while a slice or one ounce (28.35g) is common for cheddar cheese. Here’s how they stack up:
- Two tablespoons of peanut butter: Approximately 8 grams of protein.
- One ounce (28.35g) of cheddar cheese: Approximately 7 grams of protein.
While the numerical difference seems small, considering the caloric impact is important. A single tablespoon of peanut butter (around 95 calories) contains slightly more protein than a single slice of cheese (around 60 calories), but the ratio of protein to calories is higher in cheese. Additionally, cheese is a complete protein, meaning it contains all essential amino acids, unlike peanut butter.
Beyond Protein: Other Nutritional Considerations
Making an informed choice requires looking past just the protein number. The full nutritional profile, including fat content, vitamins, and minerals, paints a more complete picture of each food's health impact.
Fat Content and Health
Peanut butter and cheddar cheese differ significantly in their fat composition:
- Peanut Butter: While higher in total fat, most of this consists of heart-healthy monounsaturated and polyunsaturated fats. These fats can help lower bad (LDL) cholesterol and are beneficial for cardiovascular health when consumed in moderation.
- Cheddar Cheese: Contains less total fat than peanut butter per 100 grams but a higher proportion of saturated fat. While the link between dietary saturated fat and heart disease is still debated and context-dependent, high consumption is traditionally linked to increased LDL cholesterol.
Vitamins, Minerals, and Other Factors
Both foods offer a range of micronutrients but have different strengths:
- Cheddar Cheese: Excellent source of calcium, crucial for bone health and other bodily functions. It also provides significant amounts of Vitamin B12, phosphorus, and Vitamin K2.
- Peanut Butter: Rich in magnesium, potassium, Vitamin E, and niacin (B3). These contribute to muscle function, antioxidant protection, and energy production.

Contextual Considerations for Your Diet
The choice between peanut butter and cheddar cheese depends heavily on your individual health goals and dietary needs. If your priority is a complete protein source with a higher protein-per-calorie ratio, cheese is the better option. It is also nearly lactose-free due to the aging process, making it suitable for many with lactose intolerance. However, those watching their sodium and saturated fat intake may prefer peanut butter, which offers heart-healthy fats and a rich profile of other minerals. The presence of fiber in peanut butter is another benefit for digestive health.
Finally, portion control should be considered. A scoop of peanut butter can easily lead to overconsumption of calories, whereas a pre-portioned slice of cheese is easier to manage. For a well-rounded diet, both can have a place, but understanding their differences helps in making the right choice for each situation.

Conclusion: The Verdict Depends on Your Goals
In the battle of what has more protein, peanut butter or cheddar cheese, there is no single victor. For overall protein quantity per 100g, they are very similar. However, cheddar cheese offers more protein per calorie and is a complete protein source, which is a significant advantage for muscle synthesis. On the other hand, peanut butter provides healthier unsaturated fats and a richer profile of certain vitamins and minerals. The best choice is determined by what other nutrients you prioritize and how you manage portion control. Incorporating both, in moderation, can contribute to a balanced and healthy diet.
