The idea that certain foods can magically "cancel out" the effects of others is a nutritional myth that, while appealing, doesn't reflect how our bodies process food. While eating cheese with a sugary or high-carbohydrate food won't magically erase the sugar, the interaction between the macronutrients does offer a significant benefit for blood sugar management. By understanding the science behind this pairing, you can make more strategic dietary choices.
The Role of Macronutrients: Protein and Fat
The key to this effect lies in the high protein and fat content of most cheeses. When you consume carbohydrates, especially simple sugars, they are quickly broken down into glucose and absorbed into the bloodstream, causing a rapid rise in blood sugar. Protein and fat, however, take much longer for your body to digest.
- Slowing Digestion: When protein and fat are consumed alongside carbohydrates, they physically slow down the emptying of the stomach. This means the glucose from the carbohydrates is released into the bloodstream at a much more gradual, controlled rate.
- Moderating the Spike: Instead of a sharp, high spike in blood sugar, the effect is a flatter, more moderate curve. This is particularly beneficial for individuals concerned with blood sugar control, such as those with diabetes or prediabetes.
It's important to remember that this is not a free pass to indulge in unlimited sugary treats with a slice of cheese. The overall caloric, fat, and sodium content of the meal must still be considered, but it provides a tool for better glucose management.
The Glycemic Index of Cheese
Another reason for cheese's stabilizing effect is its inherently low glycemic index (GI). The GI is a measure of how quickly a food causes blood sugar levels to rise.
- Zero Carbohydrates, Zero Spike: Most natural cheeses, such as cheddar, Swiss, and mozzarella, contain little to no carbohydrates. As a result, they have a GI of 0 and cause no direct rise in blood glucose.
- The Importance of the Food Matrix: For people managing their blood sugar, this makes cheese an excellent companion for higher-GI foods. By integrating cheese into a meal, you can lower the overall glycemic impact of the dish.
This principle is the reason snacks like an apple with cheese are often recommended—the fiber in the apple combined with the protein and fat in the cheese creates a more balanced and sustained energy release than the apple alone.
Comparison Table: Cheeses and Their Glycemic Impact
| Cheese Type | Carbohydrates per oz | Protein per oz | GI | Blood Sugar Impact | Considerations |
|---|---|---|---|---|---|
| Cheddar | 0.4 g | 6.5 g | 0 | Very low; slows sugar absorption. | High in saturated fat and sodium. |
| Swiss | 1.5 g | 7.66 g | 0 | Very low; lower sodium option. | Good source of protein and calcium. |
| Mozzarella (part-skim) | 2 g (per 1 oz) | 7 g (per 1 oz) | ~0 | Very low; high protein, lower fat. | Contains probiotics; versatile. |
| Cottage Cheese (low-fat) | 5 g (per ½ cup) | 12 g (per ½ cup) | 10 | Low; high protein, very filling. | Great for boosting protein in snacks. |
| Parmesan | 1.5 g (per 1 oz) | 10 g (per 1 oz) | ~0 | Very low; very high protein content. | Adds strong flavor with minimal carbs. |
Practical Pairing Strategies for Blood Sugar Stability
To effectively use cheese for blood sugar management, focus on strategic pairing:
- Combine with Fruit: Instead of eating a high-sugar fruit salad alone, add some feta, blue cheese, or goat cheese. The cheese's protein and fat will temper the glycemic response from the fruit's natural sugars.
- Elevate Whole Grains: When eating whole-grain crackers or bread (which still impact blood sugar), add a slice of Swiss or cheddar. This boosts satiety and slows down the carbohydrate absorption.
- Incorporate into Desserts: If you have a sweet tooth, consider dessert-oriented pairings like blue cheese with a drizzle of honey, or ricotta with a few fresh berries. The protein and fat make the treat more satisfying with a less dramatic blood sugar effect.
The Limitations and Importance of Moderation
Despite its benefits for blood sugar management, cheese is not a magic bullet and comes with its own nutritional considerations. As with any food, moderation is key.
- High Saturated Fat and Sodium: Many cheeses are high in saturated fat and sodium. Excessive intake can increase the risk of obesity, high cholesterol, and heart disease, particularly for those with diabetes.
- Individual Variations: Individual responses can vary depending on one's metabolism and health status. Monitoring blood glucose is recommended for those with diabetes to see how different cheeses affect them personally.

Conclusion: A Tool, Not a Cancelation
In summary, the notion that cheese can "cancel out" sugar is a myth. However, its high protein, fat, and low glycemic index make it a powerful tool for moderating blood sugar spikes. By pairing cheese strategically with carbohydrates and sweets, you can slow down digestion and achieve a more stable glucose response. As always, consuming cheese in moderation and as part of a balanced diet is crucial for overall health and well-being.
Can a Person with Diabetes Eat Cheese?
Yes, cheese can be a healthy part of a balanced diet for someone with diabetes. Due to its low carbohydrate content, it does not cause rapid blood sugar spikes on its own. It’s a good source of protein and fat, which help manage glucose levels when paired with other foods. However, moderation is important due to its high calorie, fat, and sodium content.
The Role of the Food Matrix
The full nutritional context of a food, or its "food matrix," is important. With cheese, the combination of proteins (like casein and whey), fats, and other compounds all work together to influence the body's response, which is more complex than just the sum of its parts.
The Glycemic Index vs. The Food Matrix
The glycemic index (GI) is a useful tool, but the food matrix provides a more complete picture. While the GI of cheese is low, the matrix explains why its effect is stabilizing. It's the protein and fat content that alters the overall glycemic response of a meal.
