The adage "feed a cold, starve a flu" has been passed down through generations, offering seemingly simple advice on treating common illnesses. However, the truth behind this saying is more complex than it appears. In this comprehensive guide, we will delve into the scientific evidence to explore the validity of this age-old belief.
A cold is caused by viruses that primarily affect the nose and throat. These viruses thrive in warm, moist environments. Therefore, it is widely believed that drinking plenty of fluids, such as warm tea or soup, can help thin out mucus and keep respiratory passages clear. Additionally, warm liquids can provide a soothing effect on sore throats.
In contrast to a cold, the flu is caused by influenza viruses that attack the entire body, including the lungs. These viruses replicate rapidly, consuming nutrients and energy from the host's body. Restricting food intake during a flu has been suggested to reduce the availability of these resources, thereby slowing viral replication and reducing symptoms.
Numerous studies have investigated the validity of the "feed a cold, starve a flu" saying. Here are some notable findings:
Fluids and Cold Symptoms:
Calorie Restriction and Flu Symptoms:
Based on the available scientific evidence, it is clear that the "feed a cold, starve a flu" saying should be taken with caution. While fluids may provide some relief from cold symptoms, there is limited support for the claim that calorie restriction can significantly reduce flu severity.
A balanced approach is recommended for managing cold and flu illnesses:
While cold and flu symptoms usually improve within a few days to a week, it is important to seek medical attention if you experience any of the following:
Source | Study Design | Findings |
---|---|---|
JAMA Internal Medicine (2016) | RCT | Hot liquids provided temporary relief from cold symptoms, including sore throat and nasal congestion. |
Cochrane Collaboration | Systematic Review | Moderate evidence to support the use of fluids to improve cold symptoms. |
JAMA Internal Medicine (2013) | RCT | Calorie restriction by 50% during the first 48 hours of flu reduced symptom severity. |
Nutrients (2017) | Review | Insufficient evidence to support the benefits of calorie restriction for the treatment of influenza. |
