Nearly 250 Head Start workers from across Mississippi gathered Tuesday in Jackson for a Healthy Living and Eating Summit.
They did exercises inside the Mississippi Trade Mart -- simple, inexpensive activities they can do to get their preschoolers up and moving.
They also picked up nutrition tips from several chefs.
Gov. Haley Barbour told the workers they can have a positive influence on children from low-income families. About 27,000 Mississippi children attend Head Start centers.
A new federal study shows Mississippi has the highest rate of childhood obesity in the nation, at nearly 22 percent. Nationally, more than 16 percent of 10- to 17-year-olds are obese.
