New federal rules could make it tougher for kids to get their hands on "junk food" when they're in school.

U.S. Senator Kirsten Gillibrand has hailed a move by the United States Department of Agriculture to implement new standards on snacks sold in the nation's schools.

Gillibrand wants junk food eliminated from school cafeterias and vending machines.

There'll be a two-month public comment period on the USDA's proposed regulations.

Among other things, the plan would promote the availability of healthier snack foods with whole grains, low-fat dairy, fruits, vegetables or protein foods as main ingredients.

Parents would still be able to pack bagged lunches of their choosing or provide special treats for birthday parties, holiday events or other celebrations.

If the standards are adopted, they won't go into effect anytime soon. They cannot be implemented until at least one full school year after public comment is considered.
