WASHINGTON -- The United States has a bad reputation for being obsessed with junk food, but it's hard to argue that claim when fast food joints are literally everywhere -- including hospitals! Nearly 70% of U.S. hospitals affiliated with a medical school have at least one fast food restaurant inside their facilities, according to researchers with the Physicians Committee for Responsible Medicine.

The findings update a 2006 study that initially reported 63% of hospitals affiliated with medical schools had fast food eateries on the premises. The five most common fast food restaurants in hospitals are Subway, Starbucks, Au Bon Pain, Chick-fil-A, and McDonald's. The full survey details are published in the American Journal of Lifestyle Medicine.

"Making fast food like cheeseburgers and fried chicken available in hospitals is hazardous to the health of patients, visitors, and staff," says Dr. Zeeshan Ali, the paper's lead author and a nutrition program specialist with the Physicians Committee, in a media release. "Hospitals are places of healing, and any food served in hospitals should help reinforce that message with plenty of healthful meals focused on fruits, vegetables, grains, and beans."
