MEMPHIS, Tenn. — If you’re counting calories the math will soon get easier.

The Food and Drug Administration is finalizing rules that will put calorie content on menus and some vending machine items.

The rule mainly applies to chain restaurants. It also requires calorie labeling for certain alcoholic beverages and foods sold at entertainment venues such as movie theaters and amusement parks.

The vending machine rule requires companies that own or operate 20 or more vending machines to disclose calorie information.

Many restaurants have already started providing calorie information on menu items and some states have their own requirements.
