Eating and Drinking: Beneficial for Colds and Fevers.

Eating and drinking can be beneficial for both colds and fevers.

People should not really feed a cold and starve a fever. Research has indicated that eating is helpful in both cases. 

The origins of the myth are thought to date back to 1574 when a dictionary entry by lexicographer "John Withals" stated that not eating would help cool down a high temperature because the act of eating generates heat. 

Researchers now believe eating is helpful for the body to lower a fever because the increase in body temperature is a response of the immune system to fight illness, which in turn makes the body require more energy.
