In the past twenty years, there has been a 39 percent increase in the number of overweight children. One major reason is television. Not only does this lack of activity take up more of kids’ time, but while they watch, they tend to eat the junk food that is constantly being advertised at them. According to many pediatricians, up to one third of all children at age two may already be developing abnormally high cholesterol levels and clogged arteries. Quite possibly, the sluggish delivery of nutrition to the brain’s cells that this may bring about could hamper a child’s ability to learn.
