Why are malnourished people often more susceptible to colds or other infectious diseases?
The immune system needs to be healthy in order to protect people from infectious disease. The blood contains white blood cells that specifically attack bacteria and viruses. There are other white blood cells that engulf and destroy foreign particles such as bacteria in the body. These cells need to be replenished on a regular basis, so the diet must supply enough protein and vitamins to allow for the development of functional white blood cells. People who lack either protein or vitamins may not produce enough white blood cells to protect their body from infection.
