Is it Safe to Eat Cheese When Sick? A Guide to Nutrition and Illness

4 min read

While the long-held belief that dairy worsens a cold's congestion is now largely considered a myth, the safety of eating cheese when sick is more nuanced and depends heavily on your specific symptoms. This article explores the various factors to consider before adding cheese to your sick-day diet.

Quick Summary

Eating cheese when sick depends on your ailment; it can worsen digestive issues like a stomach bug but may be neutral for a cold. Pay attention to individual reactions and consider factors like lactose intolerance and cheese type before consuming.

Key Points

  • Respiratory Illnesses: Eating cheese during a cold or congestion may be safe, as the belief that it increases mucus is scientifically debunked, though some find it thickens the feeling of phlegm.

  • Stomach Illnesses: It is best to avoid cheese and other dairy products when you have a stomach bug or nausea, as the fat and lactose are difficult for an inflamed gut to digest.

  • Digestive Comfort: If you are generally lactose intolerant, even small amounts of cheese could cause issues, and this sensitivity can be heightened when you are sick.

  • Nutritional Benefits: Certain cheeses provide protein, calcium, and probiotics that can support the immune system and gut health, which can be helpful during recovery.

  • Listen to Your Body: The best approach is to pay attention to your personal response to dairy. If it causes discomfort, avoid it until you feel better.

  • Prioritize Hydration: For any illness, focusing on fluids like water and broth is more critical for recovery than consuming cheese.

The 'It Depends' Rule for Eating Cheese When Ill

There is no one-size-fits-all answer to whether you can or should eat cheese when you are sick. The suitability of cheese largely depends on the type of illness you have and how your body typically reacts to dairy. While some conditions make dairy a bad choice, other milder ailments may not require you to avoid it at all.

Cheese and Respiratory Illnesses (Colds, Congestion)

The connection between dairy consumption and increased mucus or phlegm is a long-standing myth, but science does not support it. Multiple studies have debunked the idea that dairy increases mucus production in the lungs and airways for most people. However, some people report that milk and cheese can make existing mucus feel thicker or more irritating to the throat. This perception can lead to a belief that dairy is worsening symptoms, even if the actual amount of mucus hasn't changed.

What to consider for respiratory issues:

  • Personal Sensitivity: If you have a personal history of feeling more congested after consuming dairy, it may be best to temporarily avoid it. Listening to your body is a key component of a healthy diet, especially when ill.
  • Hydration: Cheese and other dairy products can be part of your fluid intake, but staying hydrated with water, broth, and herbal teas is more effective for thinning mucus.
  • Inflammation: Current research indicates that dairy is not generally inflammatory for most people and may even have anti-inflammatory effects, particularly fermented varieties. Therefore, consuming cheese won't necessarily increase inflammation associated with your cold.

Cheese and Stomach Illnesses (Stomach Flu, Nausea)

When dealing with a stomach bug or gastroenteritis, medical professionals strongly advise avoiding dairy, including cheese. The reasons for this are clear:

  • Lactose Intolerance: During a stomach illness, your gut lining can become inflamed and temporary lactose intolerance is common, making it difficult to digest dairy products.
  • Digestive Difficulty: The high fat content in many cheeses can be hard on an already sensitive digestive system, potentially worsening nausea, vomiting, or diarrhea.
  • Risk of Food Poisoning: To prevent complications, especially if a stomach issue is caused by bacteria, it is wise to avoid certain foods. While cheese isn't always the culprit, it's safer to avoid dairy during a severe gastrointestinal illness.

Potential Benefits of Cheese When You're Sick

Despite the cautions, cheese is a nutrient-dense food that can offer benefits, especially during recovery from a non-digestive illness:

  • Protein: Cheese is a good source of protein, which is essential for tissue repair and immune function. Your body needs fuel to recover, and protein is a vital part of that process.
  • Calcium and Vitamins: Cheese provides essential minerals like calcium for bone health and vitamins like B12, which supports nerve health and red blood cell production.
  • Probiotics: Aged or fermented cheeses contain beneficial bacteria, or probiotics, that can support gut health. Since a large portion of your immune system resides in your gut, supporting its health can be beneficial.

Comparing Different Cheeses and Illness Types

Cheese Type Suitable for Cold/Congestion? Suitable for Stomach Bug? Considerations
Aged Cheeses (Cheddar, Swiss) Generally fine; low in lactose. May have probiotics. Avoid: High fat content can be hard to digest during GI issues. Good source of protein and calcium.
Soft Cheeses (Brie, Feta) Generally fine; pay attention to personal sensitivity to dairy. Avoid: Higher moisture content can be harder to digest. Check fat content. Can be high in sodium.
Low-Fat Cheeses (Cottage, Ricotta) Possibly beneficial; lower fat may be easier to digest for some. Best to Avoid: Low-fat options are still dairy and can contain lactose, which can be problematic during a stomach bug. Excellent source of protein.
Fermented Dairy (Yogurt, Kefir) Often recommended. Probiotics support the immune system. Caution: Plain, nonfat yogurt may be tolerated in small amounts; avoid sugary types. Provides probiotics for gut health.

How to Make the Right Choice for Your Body

When deciding whether to consume cheese while sick, consider these steps:

  1. Identify Your Illness: Determine if your symptoms primarily affect your respiratory or digestive system. This is the most important factor in making your decision.
  2. Assess Your Sensitivity: Pay attention to how your body reacts to dairy. If you typically feel worse after dairy when sick, trust your body and avoid it.
  3. Choose Wisely: If you feel well enough to eat cheese, choose a moderate amount. Aged cheeses, which are lower in lactose, are often a safer bet than soft, high-fat versions, particularly for those with some lactose sensitivity. Opt for options that have probiotics to support your gut.
  4. Prioritize Bland Foods: For stomach issues, stick to the BRAT diet (bananas, rice, applesauce, toast) and clear fluids initially before reintroducing dairy slowly.
  5. Stay Hydrated: Regardless of your symptoms, drinking plenty of fluids is crucial for recovery.

Conclusion

While science has largely dismissed the myth that cheese and dairy cause increased mucus, the decision to eat cheese when sick is not always straightforward. For a respiratory illness like a cold, moderate amounts may be fine, and in the case of fermented dairy, potentially beneficial due to probiotics. However, for stomach illnesses, cheese and other dairy products are typically a bad idea due to digestive difficulties. By listening to your body and considering the type of illness you have, you can make an informed choice about whether or not to include cheese in your diet while you recover.
