No matter how old your kids are, you can take steps to improve a healthy diet and to encourage good eating habits.

Family meals are nice for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children.

Tip Three: Being a Good Example
The best way for you to encourage healthy eating is to eat well yourself .Kids will follow the lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sweet drinks, you are sending the right message.
