<p>Though every cafeteria in every institution has a slightly different policy on how to serve food, the basic nutrition standards are practically identical. Across nearly all developed nations, cafeterias are required to serve certain types and amounts of food that have been accepted by a governing body as providing proper nutrition. Most cafeterias offer whole grains, dairy, protein (in the form of nuts or meat), vegetables or fruit, and a drink. Sweet or fatty foods are usually not included in the meals. Many countries also offer low-cost or free meals for low-income families at school cafeterias. Of course, other institutions have cafeterias, including hospitals, retirement homes, and summer camps, most of which do not have pay-per-meal prices, and so do not offer reduced-cost meals. Cafeterias are also beginning to crop up in public places, such as department stores. Target, Wal-Mart, and K-Mart all have small cafeterias inside, usually made up of small chain stores like Starbucks, Subway, and Pizza Hut. These, of course, do not have the same nutritional goals as do cafeterias in schools, which are obligated to provide healthy, solid meals to their students.</p>
