WOODBURY - Starting in July, new federal guidelines will force schools to make sure they are offering their students healthier options everywhere on their campuses, including vending machines.

Among the new standards, entrees will have to be less than 350 calories, and snacks or sides must be less than 200 calories.

Brentwood High School started the program early, trading their old snacks inside their vending machine for some healthier options.

Advocates say the program is not just about making sure the kids are eating healthy now, but to help them make healthier choices in the future.

The new standards do provide exceptions for some school traditions, such as bake sales and fundraisers.
