Unfortunately, most of our food supply is artificially manipulated and processed with many ingredients and additives that contribute to poor nutrition. Processed foods, sugar, and soda can weaken the immune system. These foods add nothing in the way of nutrition, and if your children fill up on a lot of them, they are not likely to eat healthy foods with essential nutrients.

The function of white blood cells is to fight and destroy germs that can cause disease.
