For centuries, the advice to “feed a cold, starve a fever” has been passed down through generations. But is there any truth to this age-old remedy? The guidance, originating as far back as , doesn’t quite align with modern medical understanding, experts say.
The idea behind the saying stems from an outdated theory: that a cold lowers the body’s temperature, and eating can help warm it up, while a fever raises the body’s temperature, and fasting can help cool it down. However, this is a simplification of complex physiological processes.
Family physician Simon Hodes, MB ChB, explains that starving yourself when you’re hungry is generally not a good idea. And, crucially, even when you have a fever, eating nutritious food can actually support your immune system in fighting off illness. A fever increases your metabolism, meaning your body burns more calories, making replenishment through food even more important.
Dehydration is a significant concern when you have a fever, as the increased body temperature can lead to fluid loss. “The main thing during any illness is to drink plenty of fluids,” Dr. Hodes emphasizes. This principle applies equally to those suffering from a cold.
Maintaining adequate hydration and energy levels is vital when dealing with a cold as well. Getting sufficient food and fluids helps the body maintain its resources to combat the infection. Most healthy adults can expect to experience two to three colds per year, while children typically have around four minor illnesses annually.
The origin of the advice can be traced to a dictionary compiled in by English lexicographer John Withals, who wrote that “fasting is a great remedy of fever.” While the phrase has endured, current medical guidelines suggest a different approach.
It’s also important to consider that it’s possible to experience both a cold and a fever simultaneously. In such cases, the advice to “feed a cold and starve a fever” becomes particularly problematic – how do you reconcile conflicting recommendations?
the best course of action when you’re sick, whether with a cold or a fever, is to listen to your body. If you’re hungry, eat. Prioritize nutritious foods that provide energy and support your immune system. And, most importantly, stay hydrated. Focusing on adequate nutrition and fluid intake is far more beneficial than adhering to outdated and potentially harmful advice.
While the saying may have historical significance, it’s clear that modern medical science has moved beyond the notion of “feeding a cold and starving a fever.” A balanced approach that prioritizes nourishment and hydration is the most effective way to support your body’s natural healing processes.
