Fast food is food which is prepared and served quickly at outlets called fast-food restaurants. It is a multi-billion dollar industry which continues to rapidly grow in many countries, as fewer people are eating at home. Ten years ago, they were practically unheard of by most of people. Nowadays their attitude to fast food has been completely changed not only in loads of conutries, but especially in the USA, the source of most of its innovation, where fast food restaurants are extremely popular. Despite the fact that previously it was considered to be very good and trendy, today youths are a lil bit more sceptic and somehow try to reduce the amount of such kind of food eaten every day. So I shall analize this topic carefully within USA.
One major advantage (as its name points at) is that is pretty fast. In the USA loads of people do not have enough time to prepare meals and wash up. They are too busy and the only way to satisfy their hunger are fast food chains, where most of meals are self-made which seems to be very important for not only buissnesmen, but also for students.
Secondly, its availability is an important issue as well. In the USA, Mc Donald’s tend to be located outside the centres of towns. They are usually found on the main roads leading in and out of town. On toll-free highways there are no service areas in the USA so the highway traffic uses the same services such as restaurants and gas stations as the people in each town. Consequently, there is no problem with finding fast food restaurants.
However, the cooking method is partly responsible for the food's unhealthyness. Fast food is commonly deep fried, and thereby contains more fat and calories. The cooking oil used to fry the food contains trans fats which are damaging to the heart. As a result, it may lead to many diseases, for instance obesity. That’s why loads of people in the USA are getting fatter and fatter.
After this, fast food may contain unwanted chemical additives hidden and lack proper labelling, which are damaging to the heart. Eating so many calories is really harmful and unhealthy, it might be dangerous to the human body. Especially one’s immune system may not work normally due to of lacks of necessary vitamins.
On balance, because of its convenience, fast food is popular in the USA and commercially successful in most modern societies, but it is often criticized for leading to obesity. Fast food portions are usually larger than the amount one should consume in a serving, so in my opinion eating in Mc Donald’s should be limited as much as possible.
