If your child is overly susceptible to illness, you may want to take steps to enhance his or her immune system and make it as strong as possible. 

The immune system fights disease-producing organisms such as bacteria, viruses, fungi, and parasites. All children are continuously exposed to these pathogens, but exposure does not mean a child will get sick.

 A strong immune system provides a child with powerful natural defences against disease. Conversely, a child with a weakened immune system is vulnerable or more susceptible to colds, flu, and more serious illnesses.

Good nutrition is essential to developing and keeping the immune system healthy and strong.
