The past 50 years have seen a dramatic increase in the availability of fast food.Yet,there remains some disagreement as to whether the overall of fast food has been positive or negative .I personally believe that the drawbacks of fast food far outweigh its benefits.

It is true that fast food revolutionised the way we take a meal.Most of us have benefited greatly from its convenience,especially to those white collars with a high salary who are always very busy and unwilling to cook themselves.They can choose a combo in fast food chains like KFC or McDonalds and finish a meal within just several minutes,instead of taking lots of time in cooking and washing dishes unwillingly.

Nevertheless,It is also a indisputable fact that fast food results in serious health problems.Foods such as fried chicken,hamburgers and chips - which are incredibly high in fat and salt - are responsible for such ailments as high blood pressure,obesity and heart disease.In addition,although I certainly agree that fast food is both convenient and affordable,the cost and inconvenient of treating the illness it caused in later life are significant.In other words,while fast food is beneficial in the short-term,its long term effects are generally negative.

By way of conclusion,I once again reaffirm my position that fast food has had a negative impact on our daily life because of its great harm to our health,even though it provided an incrediable convenient way for us to take meal.
