In 1912 the first automat food machines appeared in cafeterias in New York. They offered prepared food behind a glass window and customers paid by inserting coins into a slot. The system already existed in Berlin and in some US cities, such as Philadelphia.
The company Horn & Hardart popularized take-away food with the slogan "Less work for Mom”.
These machines were replaced by fast food restaurants. The most famous are: Kentucky Fried Chicken, Subway, Burger King, and McDonald's.
One of the most important features of fast food is that it can be consumed anywhere, and it can be served on the spot, delivered at home or eaten in the street. Examples of this type of food are pizza, hamburgers, fried chicken, tacos, sandwiches, chips, onion rings, etc.,
Nowadays, fresh food cooked at home is increasingly being replaced by industrial food cooked with preservatives and additives. Eating fast food and, furthermore, having bad habits like skipping breakfast, not eating fruit and vegetables on a daily basis, drinking soft drinks instead of water and eating sweets and junk food all damage people’s health and increase the levels of obesity.
More than nine million children and teenagers aged between 6 and 19 are considered overweight and obese.
