The Affordable Care Act is like a big box of Christmas presents: you keep rummaging around in the peanuts and find hidden treasures. Or hidden costs, as it were. Here’s one I hadn’t heard of until today:

Office workers in search of snacks will be counting calories along with their change under new labeling regulations for vending machines included in President Barack Obama’s health care overhaul law.

Requiring calorie information to be displayed on roughly 5 million vending machines nationwide will help consumers make healthier choices, says the Food and Drug Administration, which is expected to release final rules early next year. It estimates the cost to the vending machine industry at $25.8 million initially and $24 million per year after that, but says if just .02 percent of obese adults ate 100 fewer calories a week, the savings to the health care system would be at least that great.

The rules will apply to about 10,800 companies that operate 20 or more machines. Nearly three quarters of those companies have three or fewer employees, and their profit margin is extremely low, according to the National Automatic Merchandising Association. An initial investment of $2,400 plus $2,200 in annual costs is a lot of money for a small company that only clears a few thousand dollars a year, said Eric Dell, the group’s vice president for government affairs.

“The money that would be spent to comply with this - there’s no return on the investment,” he said.

In my experience, vending machines shuffle their offerings fairly frequently. If the machine operators have to change the calorie information displayed every time they swap potato chips for corn chips, then $2,200 seems like a conservative estimate of costs. But then, as Hillary Clinton said when it was suggested that her own health care plan would bankrupt small businesses, “I can’t be responsible for every undercapitalized small business in America.”
