A new review of scientific research examines whether warm soup can help cure colds and flu, a home remedy that has been trusted for generations.
A long-standing home remedy
Across generations and cultures, chicken soup has been a trusted remedy for colds and flu.
The warm, nourishing dish has long been associated with care, recovery, and comfort.
Scientific review of the evidence
Researchers conducted a systematic review of over 10,000 scientific papers to examine whether soup truly helps with respiratory infections such as the common cold, influenza, and COVID-19.

Promising findings
Out of the thousands of studies, four high-quality trials with a total of 342 participants met the scientific standards. These studies revealed encouraging results.
Faster recovery
In one study, participants who ate soup recovered up to 2.5 days faster than those who didn’t.
They also reported milder symptoms such as nasal congestion, sore throat, and fatigue.
Reduced inflammation
Those who consumed soup had lower levels of inflammation-related markers, specifically IL-6 and TNF-α, two proteins that trigger immune responses during infection.

Calming the immune response
The results suggest that soup may help moderate an overactive immune reaction, making symptoms more tolerable and recovery smoother.
Warm, hydrating, and nourishing
Soup provides warmth, fluids, and nutrients, all essential when fighting illness.
Ingredients like garlic, onions, ginger, and leafy greens have anti-inflammatory, antimicrobial, and immune-boosting properties that may support healing.
Homemade options work best
Homemade versions with vegetables, herbs, and spices, such as carrots, celery, and fresh garlic, are considered the best choice, offering natural nutrients and flavor without additives.

Easing the strain on healthcare
Simple home remedies like soup may help reduce unnecessary doctor visits for mild illnesses.
More research is needed
However, researchers point out that current studies don’t yet show how soup affects daily life outcomes, such as missed workdays or hospitalization rates.

As research suggests, it might just help you get back on your feet a little sooner.
