(April 3) Arizona’s Department of Health Services and several restaurant chains have launched a program to help consumers identify the nutrition content of menu items, the Arizona Republic reported.

A voluntary effort, The Arizona Smart Choice Program identifies menu items meeting certain healthful criteria, such as calories from fat.

McDonald's, Outback Steakhouse, Subway and Macayo's restaurants already have signed on. Restaurants involved in the program display a logo on their menus and in their windows.

The program was prompted by failed legislation that would have required restaurants to list nutritional content for all menu items, the Republic reported.
