WASHINGTON (AP) — Goodbye candy bars and sugary cookies. Hello baked chips and diet sodas.

The government for the first time is proposing broad new standards to make sure all foods sold in schools are more healthful, a change that would ban the sale of almost all candy, high-calorie sports drinks and greasy foods on campus.

Under new rules the Department of Agriculture proposed Friday, school vending machines would start selling water, lower-calorie sports drinks, diet sodas and baked chips instead. Lunchrooms that now sell fatty "a la carte" items like mozzarella sticks and nachos would have to switch to healthier pizzas, low-fat hamburgers, fruit cups and yogurt.
