Costa Cruises is making healthy dining fun for its youngest guests.  The line has revamped its menus and even incorporated an educational card game into the mix.  The new menus are influenced by the principles of a Mediterranean diet, while the card game aims to teach your children about proper nutrition and the value of making the right food choices. Pasta, fruits and vegetables are the main components of the new menu with seven menu options available daily. Each is identified by a special name: Red Planet, Yellow Planet, White Planet, Purple Planet, Green Planet, Hidden Treasure and Rainbow.  Along with their menu choice, the children will receive a package of ten playing cards. Illustrated by a famous Italian cartoonist, the cards contain characters representing fruit and vegetable colors. Children can collect and exchange all the cards (a total of 85) with each other.
