3 min read

Despite popular belief that dairy increases mucus production when sick, studies have consistently found little evidence to support this myth. However, a different question remains: is mac and cheese good when ill, or is this comfort food better saved for healthier days?

Quick Summary

Mac and cheese is a comforting, high-calorie food that can be hard to digest due to high fat and dairy content. While soothing for some mild illnesses, it can worsen symptoms like upset stomach or diarrhea; modified versions or alternatives are often better.

Key Points

High-fat risk: Traditional mac and cheese's high fat and dairy content can be hard to digest and may worsen upset stomach, nausea, or diarrhea.
Comfort vs. Cure: While comforting for a mild cold or sore throat, mac and cheese is not a medicinal food and can hinder recovery if it causes digestive distress.
Smart modifications: To make it healthier for a sensitive stomach, use lactose-free dairy, whole-wheat or rice pasta, and mix in steamed vegetables.
Consider alternatives: For serious digestive issues, stick to bland, easily digestible foods like the BRAT diet (bananas, rice, applesauce, toast) or broth-based soups instead of mac and cheese.
Listen to your body: The best approach is to listen to your body's signals and choose foods that feel right for your specific symptoms, prioritizing hydration and gentle nutrition.
Nutrition benefits: For mild illnesses, the calories and protein in mac and cheese can provide essential energy when your appetite is low.

Mac and Cheese as a Comfort Food: The Pros and Cons When Sick

When you’re feeling under the weather, a warm bowl of mac and cheese can feel like a hug from the inside. Its soft texture and familiar flavor are undeniably comforting, making it a go-to for many on sick days. The simple carbohydrate content can provide much-needed energy when your appetite is low and cooking feels like a chore. For a sore throat, the creamy sauce and soft noodles can be easier to swallow than more solid or crunchy foods. However, the comfort factor doesn't automatically mean it’s the best choice for your body, depending on your symptoms.

The Comforting Upside of Mac and Cheese

For mild ailments like a common cold, without significant digestive upset, mac and cheese can serve a purpose. It is a calorie-dense food that can help prevent weight loss when you have no appetite. The protein from the cheese is also beneficial for providing the building blocks your body needs for recovery. The psychological comfort of eating a nostalgic meal can also have a positive effect on mood, which is a small but welcome benefit when you feel crummy.

The Digestive Downside of Traditional Mac and Cheese

On the flip side, traditional mac and cheese is high in fat, sodium, and dairy—a triple threat for a compromised digestive system. If you have an upset stomach, nausea, or are experiencing diarrhea, rich, fatty dairy products are often the first thing to avoid. The high fat content is particularly hard to digest and can aggravate gastritis or other gastrointestinal issues. Furthermore, many popular boxed varieties use refined white pasta and are low in fiber, which can lead to constipation. In these cases, the heavy nature of the meal can make you feel worse, not better.

When to Choose Mac and Cheese and When to Avoid It

Consider your symptoms: If your primary issue is a head cold, sore throat, or general fatigue without stomach problems, a small portion of mac and cheese may be acceptable. If you have nausea, vomiting, or diarrhea, it is best to avoid it entirely.
Hydration is key: Remember that regardless of your food choice, staying hydrated is paramount when you're ill. Broth, electrolyte drinks, and water are always the best foundation for recovery.
Moderation is critical: Even if you decide to have mac and cheese, opt for a small serving. Overeating when your body is fighting an infection can strain your digestive system and divert energy away from healing.

Healthier Alternatives and Modifications

If you are set on the comfort of mac and cheese but know your stomach is sensitive, consider these modifications.

Lighter Mac and Cheese Modifications

Use lactose-free dairy: If lactose intolerance is a concern, use lactose-free milk and cheese substitutes.
Choose alternative pasta: Opt for whole-wheat, rice, or gluten-free pasta, which may be gentler on digestion.
Incorporate vegetables: Stir in steamed broccoli, spinach, or grated carrots to boost fiber, vitamins, and minerals.
Create a lighter sauce: Reduce the amount of cheese or fat and use a base of pureed cauliflower or vegetable broth to thin the sauce.
Prioritize hydration: Pair your meal with plenty of water or clear broths. Comparison of Sick Day Foods

Conclusion: Listen to Your Body

Ultimately, whether mac and cheese is a good choice when you're ill depends on your specific symptoms. It can be a comforting and caloric meal for a mild cold, but it's often a poor choice for a sensitive stomach due to its high fat and dairy content. Lighter, modified versions are a better compromise for those seeking comfort without the digestive stress. Pay close attention to what your body is telling you, and when in doubt, stick to bland, easily digestible foods like those found in the BRAT diet.
