Many might believe that the citrusy flavor of some fruits may become a cause of a sore throat or catching a cold. However, this is certainly not the case, and in fact, consuming citrus fruits like oranges, tangerines, grapefruits, lemons, lime, etc, is often recommended when sick and on regular days as well.
