To help them make good food choices, Excellus BlueCross BlueShield has donated a tool to Corning-Painted Post students. YNN's Katie Husband tells us, with a quick snap, a healthy serving is checked off the list for the day.

CORNING, N.Y. -- You know what they say, 'an apple a day keeps the doctor away.' And Erwin native, Lisa Johnson, wants to prove that with her new product, An Apple A Day. It was inspired five years ago when she was looking for a tool to help with her kids' eating habits.

"So I went to my brother who's the co-creator of the tracker and he's got a background in visual communication and design and we started putting something together and four years later we launched An Apple A Day.com and brought the nutrition tracker to market," said Lisa Johnson, An Apple A Day, president and co-founder.

The tracker comes with cards that can be removed and replaced in the device that show different foods and gives healthy eating tips. Johnson shows us how to use it before heading into the classroom.

"The child starts the day with all of the doors open and their goal is to close all of the doors by the end of the day. So as they eat a serving they snap the door shut," said Johnson.

Excellus BlueCross BlueShield donated 450 of the items to these second graders, where they can take them home to keep track with their families.

"And because it engages the whole family. We really feel getting the whole family involved. Involving the whole family in the process is really the core of making healthy choices," said Johnson.

The district thought An Apple A Day was the perfect tool to get students involved in making healthy food choices.

"But, this makes it easy to understand and it's going to build some excellent skills for life that's going to take the students of C-PP into the future and adulthood in healthy eating," said Joe Kilmer, Corning-Painted Post School District, director of food services.

A tool that was used in Johnson's home has now spread to others and thanks to a simple 'snap' these kids can be on their way to healthier eating habits.
