The age-old saying, “Feed a cold and starve a fever,” has been passed down through generations, but is there any truth to it? This advice, which dates back to 1574 from an English dictionary by John Withals, suggests that fasting can remedy a fever, aligning with historical medical practices of starving or bleeding patients to reduce body heat. However, does this tradition hold any scientific merit today?
To explore this question, UVA Today consulted Beth Quatrara, an associate professor at the University of Virginia School of Nursing, for her expert insights on whether dietary habits can influence recovery from illness.
Debunking the Old Saying
Contrary to popular belief, there’s no scientific evidence to support the notion that one should feed a cold and starve a fever. Quatrara explains, “There are health care traditions that have been passed down from generation to generation, and some of them do work. There’s science that shows eating chicken noodle soup has benefits when you’re sick. But feeding a cold and starving a fever is definitely not backed.”
Staying hydrated is crucial when sick, and it’s advisable to avoid alcoholic, caffeinated, or sugary drinks while recovering. Quatrara emphasizes, “Starving is not good. You want to have a lot of fluids on board because – not to be gross – but your sinuses are clogged up, and you want to thin those secretions.”
It’s worth noting that colds and fevers can coincide. While a cold is usually a viral infection, fevers are the body’s way of combating infections. If your fever surpasses 100 degrees, it’s important to seek medical attention.
Can Diets Prevent Illness?
While there’s no magic food that wards off illness, maintaining a balanced diet is key. Quatrara advises focusing on protein intake, noting, “We want our immune systems to get rid of the cold, get rid of the fever, and our immune system is based on proteins.”
For those already feeling unwell, consuming foods rich in antioxidants, such as vegetables, berries, and greens, may offer anti-inflammatory benefits. Honey is known for soothing sore throats and also possesses anti-inflammatory properties, as do citrus fruits and ginger, which is why teas often feature combinations of lemon, ginger, and honey.
