Snack machines try to shake junk-food image

It was only a matter of time.

First, supermarkets began offering low-fat, low-salt and, more recently, low-carbohydrate versions of traditional foods.

Then restaurants and fast-food chains modified their menus, adding broiled versions of fried standards and alternatives to the bread-and-pasta staples.

Now that last bastion of junk snacking has seen the light. Vending machines are turning healthful, or at least less unhealthful.

Driven by consumer demand for items with less fat, salt, sugar or carbohydrates and by school system bans on traditional junk food, companies have begun to offer more nutritious options for snackers away from home.

Established snack-food distributors say they're adding reduced-fat and lower-calorie alternatives to the standard offerings and are placing yogurt, smoothies and fruit in refrigerated machines.

Newer companies have sensed an opportunity as well, particularly when it comes to the low-carbohydrate craze.

"The fact is that obesity and diabetes are going to be on everyone's radar screen for the next 20 years," said Joe Preston, co-founder of Low Carb Vending in Bethesda, Md. "These products are flying off the shelves in grocery stores, drugstores and [discount] stores like Sam's Club. The next evolution is to provide the customer with convenience."

The company has installed three low-carbohydrate-only vending machines in the Washington, D.C., area and has deals to supply Atkins, Carbwise and Carb Solutions brand nutrition bars, candy bars, chips and shakes to other vending companies in several cities. It also sells and leases its own brand machines.

Pure Foods, a Beverly Hills-based company with stores in Santa Monica and Beverly Hills, announced in January the launch of Pure Foods Vending, which will provide machines stocked with low-carbohydrate, sugar-free and low-fat items, plus natural and organic snacks; it will also distribute those products to other vending machine companies.

Although industry buzz is all about "healthy" vending, many packaged snacks catering to dieters and other health-conscious people can at best be called "healthier," said Matthew Marsh, president of First Class Vending in Los Angeles, a large Southern California vending machine company. "Nutri-Grain bars are healthier than a candy bar but not as healthy as a piece of fruit," he said.
