Reading up on how to get children to eat  the food their bodies need.  Many opinions, but here's mine:

 Prepare a good healthy dinner.

 Announce that this is it,

 nothing else til breakfast.

  Don't cave in!

   When our children learn to eat and be grateful for 

the things we place before them, they also are learning respect for the one who serves them and necessary discipline.  We can not always expect to get our own way.

  If a certain food does not agree with their taste buds, they do not need to feel obligated to eat all of it, but should not expect that food to be replaced with something else; and no extra snacking privileges to make up for it!  Don't kid yourself.  They will NOT starve.  They will just be good and hungry for the next meal and, this time, less picky.

  When you see a willingness to cooperate, try new foods.  Reward their good habits by letting them help you plan the menu.  Share with them how you have learned to overcome food obstacles in your own life so that you can get the right foods into your body. This way, they can learn how good choices are made and even, one day, treat you to a good home prepared meal.  It's not all about ourselves, after all. It's about caring for and taking care of each other too.
