The company, Sodexo, says some of the changes could be in place as soon as next year.
Sodexo is pledging to add more nutritious options to its vending and K-12 lunchroom programs. It also says it will offer a healthier children's meal at such places as museums, aquariums and other recreational venues. The company also wants to serve millions more free breakfast meals in the primary and secondary schools it serves.
CEO George Chavel says the company serves 15 million consumers a day, including adult role models for kids.
A formal announcement company was expected Thursday at a health summit in Washington.
