What's Unhealthy About Cheese? An In-Depth Look at Its Nutritional Drawbacks

5 min read

According to the CDC, soft cheeses made with unpasteurized milk can be contaminated with Listeria bacteria, posing a serious health risk. While celebrated for its flavor, it is worth exploring what's unhealthy about cheese to understand its potential impact on your diet and health.

Quick Summary

Cheese can be high in saturated fat, sodium, and calories, which may contribute to heart disease and weight gain when overconsumed. Additionally, it can cause digestive problems for those with lactose intolerance and carries a risk of bacterial contamination in some varieties.

Key Points

  • High in Saturated Fat: Many cheeses contain significant amounts of saturated fat, which can raise bad cholesterol levels and increase the risk of heart disease.

  • Excess Sodium Content: Due to its use in production, cheese is often high in sodium, contributing to concerns like high blood pressure.

  • High in Calories: Cheese is calorie-dense, and consuming too much can lead to an excess calorie intake, potentially causing weight gain.

  • Potential for Digestive Issues: Lactose intolerance or casein sensitivity can lead to bloating, gas, and stomach cramps for many individuals after eating cheese.

  • Listeria Risk in Soft Cheeses: Unpasteurized soft cheeses can be contaminated with Listeria bacteria, posing a food safety risk, especially for vulnerable populations.

  • Moderation is Key: Enjoying cheese in small portions and as part of a balanced diet can mitigate many of its potential negative health effects.

Understanding the Nutritional Drawbacks of Cheese

Cheese is a dairy product known for its rich flavor and versatility, but it also comes with several nutritional considerations. While it offers valuable nutrients like calcium and protein, certain components, when consumed in excess, can pose health risks for many individuals. Understanding these drawbacks is key to enjoying cheese as part of a balanced diet.

High Saturated Fat Content

Most types of cheese are high in fat, and a significant portion of this is saturated fat. For years, health organizations like the American Heart Association have advised limiting saturated fat intake, as it can raise levels of low-density lipoprotein (LDL), or "bad" cholesterol, in the blood. Elevated LDL cholesterol is a known risk factor for cardiovascular disease and stroke.

However, some newer research indicates the relationship between saturated fat in dairy and heart health may be more complex. Fermentation processes in certain cheeses can produce beneficial compounds that might counteract some negative effects. Despite this, heavy consumption of high-fat cheese, particularly when paired with other unhealthy foods like processed meats and refined grains in dishes like pizza or burgers, can still contribute to poor cardiovascular outcomes. Moderate intake, and being mindful of your total saturated fat for the day, is the wisest approach.

A Significant Source of Sodium

Salt is a critical component in cheese production, used to control moisture, preserve flavor, and inhibit the growth of unwanted bacteria. Consequently, many cheeses are loaded with sodium. Excessive sodium intake is a major contributor to high blood pressure, increasing the risk of heart disease and stroke. Processed and some harder cheeses are particularly high in sodium, with a single ounce of American cheese containing a significant amount of your daily recommended intake. Those monitoring their blood pressure or sodium intake should be especially cautious with portion sizes and opt for lower-sodium varieties like Swiss cheese.

The Calorie-Dense Nature of Cheese

Cheese is a calorie-dense food, meaning a small serving can contain a high number of calories. This makes it very easy to overconsume calories without realizing it, which can lead to weight gain over time. While cheese does offer satiety from its fat and protein content, the ease of adding it to many meals (think of a heavy sprinkling on pasta or a generous layer on a sandwich) means calories can add up quickly. Portion control is crucial for those watching their weight, as even a small amount of extra cheese each day can contribute to significant weight gain over a year.

Digestive Issues: Lactose Intolerance and Casein Sensitivity

Many people experience digestive distress after eating cheese due to lactose intolerance, which is the body's inability to fully digest lactose, the sugar found in milk. The severity of symptoms like gas, bloating, and diarrhea depends on the individual's tolerance and the lactose content of the cheese. Fortunately, aged, hard cheeses like Parmesan and cheddar contain very little lactose, so they are often better tolerated by those with sensitivity.

Less common is a sensitivity or allergy to casein, a protein in milk that is highly concentrated in cheese. Symptoms can range from digestive issues to more serious allergic reactions, and those with a diagnosed milk allergy should avoid cheese and other dairy products entirely.

Potential Contamination Risks in Soft Cheeses

For most healthy adults, cheese is safe to eat. However, soft cheeses and blue-veined cheeses made with unpasteurized or “raw” milk carry a risk of contamination with Listeria monocytogenes. This can cause listeriosis, a serious foodborne illness, especially for pregnant individuals, older adults, and those with weakened immune systems. Always check labels and choose products made with pasteurized milk, particularly if you are in a high-risk group.

A Comparison of Cheeses: Nutritional Snapshot

Type of Cheese Approx. Saturated Fat (per 1 oz) Approx. Sodium (per 1 oz) Notes
Cheddar 9.4g ~192mg High in saturated fat and calories.
Feta 6.1g ~323mg Lower fat but very high in sodium.
Swiss 8.8g ~53mg Lower sodium option, but still high in fat.
Mozzarella (Part-Skim) 6.3g ~170mg A lower-fat choice, good for melting.
Parmesan 9.4g (regular) Very high, but used sparingly Hard cheese, often used as a sprinkle.
Cottage Cheese (4% Fat) 3g (per 1/2 cup) ~350-480mg (per 1/2 cup) Higher protein, but check sodium content.

Making Healthier Choices

The key to managing the unhealthy aspects of cheese is moderation and mindful selection. Incorporating cheese into a healthy lifestyle is possible by making some simple swaps and being aware of portion sizes.

  • Portion Control: The standard serving size for cheese is about one ounce, roughly the size of a matchbox. Stick to this guideline to keep calories and fat in check.
  • Choose Lower-Fat and Lower-Sodium Options: Opt for cheeses that are naturally lower in fat, like part-skim mozzarella, or lower in sodium, such as Swiss cheese. Alternatively, use smaller amounts of strong-flavored, salty cheeses like Parmesan or feta to add a powerful taste without adding excess sodium.
  • Pair with Healthy Foods: Instead of pairing cheese with processed carbs, enjoy it with fiber-rich foods like fruits, vegetables, and whole-grain crackers.
  • Use as a Flavor Enhancer: Use cheese sparingly as a garnish rather than the main event. A light grating of a strong cheese can provide plenty of flavor for fewer calories.
  • Explore Alternatives: For those with dairy sensitivities or seeking to reduce dairy intake, alternatives like nutritional yeast or cashew-based sauces can mimic the flavor of cheese.

Conclusion

While delicious and nutritious, cheese has several unhealthy aspects related to its high saturated fat, sodium, and calorie content. For individuals with specific dietary concerns, such as high blood pressure, elevated cholesterol, or lactose intolerance, consuming large amounts can be problematic. However, this doesn't mean cheese should be avoided entirely. By being mindful of portion sizes, choosing lower-fat or lower-sodium varieties, and pairing it with whole, unprocessed foods, you can enjoy cheese in moderation as part of a healthy lifestyle. As always, listening to your body and consulting a healthcare professional for personalized dietary advice is recommended. The key is balance, not banishment, when it comes to this popular food.
