You cannot have it towed to the local dump and buy a new one. We need to water it, and feed it and pamper it. If, however, you eat a diet that is lacking in the vital nutrients, as junk food typically is, your body will begin to show signs of neglect and abuse. Eating properly, according to a recomended diet such as the Canada Food Guide will go a long way towards keeping you and your body feeling well and working well. Teaching your children to eat well is one of the best ways to keep them healthy for life.
Proper nutrition builds up the immune system so that it can fight germ invaders effectively.
Kids who don't eat well don't grow well and get sick more often, and stay sick longer that kids who do eat a balanced diet. Look at what your children eat and provide what they need to grow. If you buy junk, the kids will eat junk. If you buy healthy, the kids will eat healthy. You as the parents are the gatekeepers to your childrens mouths.
