Scientists say that junk food is harmful to people's health. Some say the way to ask people to eat less fast food is to educate them, while others say education does not work. Discuss both sides and give your own opinion. The past 50 years have seen a dramatic increase in the availability of the junk food because of its low cost and convenience,and now it has become an indispensable part of life in modern fast-paced society.At the meantime,the increasing number of people has begun to pay more attention to the negative effects of the junk food. Some people think through education,individuals will come to realize that cosuming junk food to excess is detrimental to the health.For example,the public service advertisements can tell the audience that most junk food contains harmful substances such as cholesterol,preservatives and additives,and more importantly ,excessive intake of fast food will include a host of epidemic like obesity cardiovascular diseases. After receiving the education,some people who are addictive to these food may turn to the natural food,pursing a more healthy diet. Although the education may work,its influence is limited.Some other methods can not be negelected.Firstly,the government should enact more rigid law and regulations to restrict junk food advertisements and promotion,especially those targeting at children.Secondly,the government can also impose a higher tax on fast food restaurants to raise the price of the product and then reduce people’s reliance on the junk food.Thirdly, given the health risks of the,people may be still inclined to choose the fast food because the healthy food always links to the high price.So,policy makers should subsidize natural food, helping the panoply of institutions selling natural food capture a large slice of the market with affordable price and eventually provide a more reasonable price for people to cosume. In conclusion,limits on the advertisements,higher tax and subsidization are very efficient solutions,other than education.However,more importantly,people should enhance the awareness of healthy diet and boycott the junk food.
