Junk food is simply irresistible, but it is certainly not good for health. There are a number of reasons behind this. The main problem is that fast-food is not always prepared in clean and hygienic conditions.
Those preparing and serving burgers and other items are liable to spread diseases and infection through dirty and unclean hands. Chances of food poisoning are more if the personnel handling fast-food appear in dirty clothes too.
They are often not trained properly in maintaining hygiene.
All the same, burgers and French fries are quite irresistible and unavoidable. Everything is deep-fried. This action robs them of the protein and vitamins they contain and are required for our healthy beings. Besides this, they contain a lot of fat and are more oily.
Fast-food must be served fresh. So, it has to be preserved in its fresh from the time of preparation to the time it is finally served. For this, it banks on preservatives and chemicals.
There is always a difference between healthy preservatives used in fast-food and unhealthy ones used in them. They often contain artificial colors that are capable of causing cancer in those who consume them.
Another disturbing aspect of fast-food is the amount of animal fats they contain. Animal fats are known to be detrimental to one's health. But when you dig into a chicken-burger or a preparation from KFC, unconsciously, you dig your teeth into some amount of animal fat.
This is also alarming for those in favor of animals and animal rights.
