The Agriculture Department announced Thursday that for the first time they are regulating all foods sold in the nation's 100,000 schools by expanding new fat, calorie, sugar and sodium limits, which will mean the end of high calorie sports drinks and candy bars.
The unhealthy snacks will be replaced with diet drinks, granola bars and other healthier items.
The changes are apart of the Child Nutrition Act passed by Congress in 2010 in an effort to battle childhood obesity.
School lunch menus will also change: greasy foods will be replaced by items like low-fat hamburgers, fruit cups and yogurt.
"It's not enough for it to be low in problem nutrients, it also has to provide positive nutritional benefits," said Margo Wootan, a nutrition lobbyist for the Center for Science in the Public Interest who has lobbied for the new rules. "There has to be some food in the food."
The food industry is on board and has been working with Congress to implement the changes.
