16. Food is fuel for your body and has a direct
impact on how you feel as well as on your
overall health. Fast food refers to food
that can be served quickly. In many cases,
that means food that is highly processed
and contains large amounts of
carbohydrates, added sugar, unhealthy
fats, and salt (sodium). These foods
generally contain a high number of
calories but offer little or no nutritional
value.

17. The concept of fast food is generally associated with urban
development. However, research reveals that the trend has
its roots in the bread-and-wine stands in ancient Rome and
the popular ready-to-eat noodle shops in many East Asian
cities. All through the ancient and medieval world, flat-
bread, falafel and other heat-and-serve meals were popular
attractions at roadside stands.
