Cheese is a delicious and versatile food enjoyed worldwide, but not all cheeses are created equal. Depending on individual health needs, some varieties are best limited or avoided. These concerns range from bacterial contamination risks to high levels of saturated fat, sodium, and additives in processed products. Understanding the potential downsides of certain cheeses is key to a healthier diet.
The Dangers of Unpasteurized Cheeses
One of the most critical reasons to avoid certain cheeses is the risk of contamination with harmful bacteria, particularly Listeria monocytogenes. Listeria infection, or listeriosis, can cause severe illness, especially in pregnant women, newborns, the elderly, and those with weakened immune systems. The primary risk comes from unpasteurized (raw) milk, which is not heated to a temperature sufficient to kill bacteria.
Cheeses to Avoid Due to Listeria Risk
- Soft, mold-ripened cheeses: Varieties like Brie, Camembert, and certain chèvre (goat cheese) have higher moisture content and lower acidity, creating an ideal environment for bacteria to grow. Always check the label to ensure they are made with pasteurized milk, or cook them until steaming hot to eliminate the risk.
- Soft blue-veined cheeses: This includes Roquefort, Gorgonzola, and Danish Blue. These cheeses are also higher in moisture and are only safe to consume if cooked thoroughly.
- Certain Latin-style cheeses: Fresh, soft cheeses such as Queso Fresco, Queso Blanco, and Panela have been linked to listeria outbreaks, even when labeled as pasteurized. This is often due to improper sanitation during production.
Steering Clear of Highly Processed Cheese
Processed cheese is fundamentally different from natural cheese. Products like American cheese singles, Velveeta, and cheese spreads are made by melting and blending natural cheeses with other ingredients. These additions are designed to improve shelf life, melting consistency, and flavor, but come at a cost to nutritional value.
Why Processed Cheese is Best Avoided
- Excessive Additives: Processed cheese contains emulsifying agents (like sodium phosphate), artificial colors, preservatives (sorbic acid), and flavorings. These are not present in natural, minimally processed cheeses.
- High Sodium Content: To enhance flavor and act as a preservative, a significant amount of salt is added to processed cheese. A single slice of American cheese can contain around 400mg of sodium, contributing to high blood pressure and heart disease risk.
- High Saturated Fat: Many processed cheese products are high in saturated fat and cholesterol, which can contribute to plaque buildup in arteries.
- Reduced Nutritional Value: The heavy processing strips away much of the natural cheese’s nutritional value, leaving a product with very little fiber and fewer nutrients.
High-Fat and High-Sodium Cheese Varieties
Even among natural cheeses, some varieties are much richer in saturated fat and sodium than others. While not inherently unhealthy in moderation, excessive consumption can pose risks for heart health and blood pressure.
- High Saturated Fat Cheeses: Rich, creamy cheeses, especially triple-cream varieties, pack a high saturated fat punch. Mascarpone, with its high cream content, is particularly rich. Other examples include Brie and aged Cheddar.
- High Sodium Cheeses: The aging and brining process for many cheeses increases their salt content significantly. Feta is stored in brine, giving it high sodium levels, while hard cheeses like Parmesan and Roquefort develop high salt content during their long aging process. Halloumi, a brined and grilled cheese, is also very high in salt.
High-Fat and Low-Fat Cheese Comparison
| Cheese Type | Total Fat (per 100g) | Sodium Content (per 100g) | Healthier Alternative |
|---|---|---|---|
| Mascarpone | ~42g | Low | Ricotta |
| Brie | ~31g | 629mg | Low-fat cream cheese or mozzarella |
| Roquefort | ~31.3g | 1809mg | Feta (in smaller portions) |
| Cheddar | ~34.9g | 653mg | Reduced-fat cheddar |
| Parmesan | ~29.7g | 1804mg | Use sparingly as a garnish |
| Feta | ~23g | 917mg | Cottage cheese |
Aged Cheeses and Histamine Intolerance
Some individuals experience a condition known as histamine intolerance, where the body cannot effectively break down histamine. This can lead to various symptoms, including headaches, skin issues, and digestive problems. Aged and fermented cheeses are particularly high in histamine due to the breakdown of amino acids during maturation.
Cheeses to Watch with Histamine Intolerance
- Hard, aged cheeses: This includes Parmesan, aged Cheddar, Swiss, and Gouda, which build up high levels of histamine over their long ripening period.
- Blue-veined cheeses: The mold in blue cheeses, like Gorgonzola, also contributes to a higher histamine content.
For those sensitive, fresh, un-aged cheeses like ricotta, mozzarella, and cream cheese are better options.
Conclusion: Choosing Wisely for Your Health
While cheese can be a nutritious source of protein and calcium, not all types offer the same health benefits. For better health, it's wise to avoid or limit unpasteurized soft and blue cheeses to prevent bacterial contamination. Heavily processed cheese products should be limited due to high levels of sodium, fat, and artificial additives. For those watching their fat and sodium intake, moderation is key with rich, aged cheeses. Individuals with histamine intolerance should stick to fresher, less aged varieties. By being mindful of these considerations, you can enjoy cheese as part of a balanced and healthy diet.
