Blue Cross Blue Shield of Arizona is offering a free health education program to fourth- and fifth-grade students in the state in an effort to promote the importance of good nutrition and movement to young people.

Blue Cross Blue Shield of Arizona is making its Walk On! Challenge available to elementary school teachers to help expand their students’ education about the importance of healthy eating and physical activity.

"The Walk On! Challenge is part of Nourishing Arizona, Blue Cross Blue Shield of Arizona's initiative to improve the health of Arizonans through nutrition education and healthy eating programs," Blue Cross Blue Shield Arizona Chief Medical Officer Dr. Vishu Jhaveri said in a press release. "Childhood obesity is a concern for nearly all families across the county. Research shows the epidemic is affecting our children now and into adulthood. The Walk On! Challenge is an easy and effective way for teachers to make a difference in their students' lives. It helps children become more aware of their day-to-day choices, which will set the stage for healthy habits the rest of their lives."

The program is based on what is known as 5-2-1-0 principles which include five fruits and vegetables, two hours or less of screen time, one hour of physical activity and zero sugary drinks.
