Politico:

Democrats want you to know that your McDonald's Angus Burger meal has about 1,500 calories -- before you buy and burp.
Buried deep in the House health care bill is a provision, likely to raise nanny-state hackles, requiring fast-food chains and vending machine owners to notify customers of calorie counts -- by conspicuously posting nutritional information on menus or machines.
The provision -- Section 2572 -- requires retail food establishments "part of a chain with 20 or more locations" to list calorie counts "on the menu board including a drive-through board," as is currently required in New York City and other localities.
