For centuries, a warm bowl of soup has been the universal prescription for feeling unwell, a comforting ritual passed down through generations. While the act of a loved one serving a steaming bowl provides significant psychological comfort, the restorative effects of soup are backed by a surprising amount of science. From rehydration and soothing inflamed tissues to providing a dose of easily absorbable nutrients, there are several powerful reasons why does soup help you get better.
The Power of Hydration and Electrolytes
One of the most critical factors for recovering from an illness like the cold, flu, or a stomach bug is staying hydrated. Conditions such as fever, vomiting, and diarrhea deplete the body of fluids and essential electrolytes. Broth-based soups are an exceptional way to replenish these lost fluids. Unlike plain water, the broth provides flavor that can stimulate a low appetite and contains important electrolytes like sodium and potassium. This makes it a more satisfying and effective way to fight dehydration, helping you avoid that drained, sluggish feeling that often accompanies sickness.
A Nutrient-Dense and Easily Digestible Meal
When your body is busy fighting an infection, it redirects energy away from non-essential functions, including digestion. This is why many people experience a loss of appetite when sick. Soup addresses this by providing calories, protein, and a variety of vitamins and minerals in a form that is easy for the body to process. Protein from chicken, for example, supports immune function by providing the building blocks for antibodies. Vegetables like carrots, celery, and onions contribute vitamins A and C and powerful antioxidants that help fight infection. The cooking process breaks down the fibers, making these nutrients more readily available for absorption.
Anti-Inflammatory and Symptom-Soothing Effects
Beyond basic nutrition, many components of soup possess specific properties that can help alleviate symptoms. Research has shown that chicken soup, specifically, may have an anti-inflammatory effect. A 2000 study from the University of Nebraska Medical Center found that some components of chicken soup inhibit the migration of neutrophils (white blood cells) in vitro, suggesting a potential anti-inflammatory action that could ease symptoms of upper respiratory infections.
Furthermore, the ingredients commonly added to soup can provide powerful, targeted relief:
- Garlic and Onions: Contain compounds like allicin that offer antibacterial and anti-inflammatory properties.
- Ginger and Turmeric: These roots have well-known anti-inflammatory and antioxidant effects.
- Chicken (Amino Acids): The amino acid cysteine in chicken is chemically similar to a medication used to treat bronchitis and helps break up mucus. Carnosine, another compound, may also reduce inflammation.
- Hot Steam: The simple act of breathing in the warm vapor from a hot bowl of soup can help open up nasal passages and clear congestion.
The Benefits of Bone Broth
While any homemade soup offers benefits, bone broth provides an extra boost. Slow-simmering chicken or beef bones releases nutrients like gelatin, collagen, and amino acids such as glycine and glutamine. These compounds are believed to help heal the gut lining, which is closely linked to overall immune function. A healthy gut can more effectively absorb nutrients and support the immune system's fight against illness. This makes bone broth a particularly restorative base for a healing soup.
Canned vs. Homemade Soup: What's the Difference?
| Feature | Homemade Soup | Canned Soup |
|---|---|---|
| Nutrient Density | Higher, as ingredients are fresh and cooking methods retain vitamins and minerals. | Often lower due to processing, and some nutrients can be lost. |
| Sodium Content | You can control the amount of salt used, making it much lower. | Typically very high in sodium to act as a preservative. |
| Ingredients | Fresh, whole ingredients you choose, including more nutrient-rich options like bone broth. | Often contains preservatives, artificial flavors, and processed ingredients. |
| Anti-Inflammatory | Higher potential due to fresh herbs and spices like ginger, garlic, and turmeric. | Lower potential, as active compounds may be degraded by processing. |
| Cost | Generally more affordable, especially when using seasonal produce. | Can be cheap and convenient for a quick meal. |
The Role of Psychological Comfort
Never underestimate the power of comfort food during recovery. The familiar warmth and taste of soup, often associated with childhood and care, can reduce stress and anxiety. Stress can hinder the immune system, so anything that promotes relaxation and a sense of well-being is beneficial. The emotional support and comfort that come with enjoying a bowl of soup are an integral, non-scientific part of its healing power.
Conclusion: More Than Just a Myth
From hydrating the body with electrolytes to delivering easily digestible, immune-boosting nutrients, the reasons why does soup help you get better are many and varied. The hot steam clears congestion, while potent anti-inflammatory ingredients get to work at a cellular level. Whether you opt for a traditional chicken noodle or a modern vegetable-based blend, soup provides a powerful combination of physical nourishment and psychological comfort to aid recovery. Paired with rest and plenty of fluids, it remains a time-tested and effective tool for getting back on your feet.
