Dr. Jenna Macciochi, an immunologist, was interviewed by Dr. Rangan Chatterjee. She explained that immune responses require a great deal of extra energy from your cells. This is the reason for feeling tired when your body is fighting an infection. High blood sugar impairs neutrophils - cells of the immune system - from working properly. My mother always gave me flat ginger ale when I was sick as a child. However, ginger tea (without sugar) or plain ginger would have been a better choice. You can even grow it!
