　　Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled ¡ª to $1.01 per pack ¡ª smokers have jammed telephone ¡°quit lines¡± across the country seeking to kick the habit.
　　This is not a surprise to public health advocates. They¡¯ve studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase.
　　The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health. They raise money and most particularly, and they deter people from tap the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely.
　　In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drugstore Wednesday. Charleston, S, C£®£¬ where the 7-cent-a-pack tax is the lowest in the nation. The price was $4.78.   
　　The influence is obvious.
　　In New York, high school smoking hit a new low in the latest surveys ¡ª 13.8%, far below the national average. By comparison, 26% of high school students smoke in cky, Other low-tax states have similarly depressing teen-smoking records.
　　Hal Rogers, Representative from cky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans ¡°who choose to smoke.¡±  
　　That¡¯s true, but there is more reason in keeping future generations of low-income workers from getting hooked in the first place. As for today¡¯s adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.

　　Ask any group of teenagers in the UK what they most like to eat, and foods like pizzas, curries, pasta, burgers and chips are bound to get a mention ¡ª and many young people would probably also list hanging out at the local fast-food restaurant as one of their favorite pastimes (ÏûDz).
　　But what teenagers like to eat is not necessarily what they should be eating. According to the National Diet and Nutrition Survey, far too many young people in the UK between the ages of 4 and 18 consume too much fat, sugar and salt in their diet and take in too many calories. Meanwhile their intake of starchy carbohydrates (º¬µí·ÛµÄ̼ˮ»¯ºÏÎï), fibre, iron, vitamins and calcium is too low.
　　For a growing body, eating foods containing plenty of calcium, such as milrt and cheese, is particularly important as calcium is essential for the development of healthy, strong bones. Similarly, foods that are rich in iron are good for young, rapidly developing bodies, so red meat, bread, green vegetables, dried fruit and fortified (ÓªÑøÇ¿»¯µÄ) breakfast cereals are also recommended.
　　It is during our teenage years that lifestyle habits can become entrenched (È·Á¢µÄ), so it is crucial that young people are educated about what foods are good for them. In 2005, and in an attempt to change eating habits and open teenagers¡¯ minds to new flavours and new tastes, celebrity chef Jamie Oliver launched a ¡°Feed Me Better¡± campaign. As a part of television series, ¡°Jamie¡¯s School Diners¡±£¬ he worked with teachers and cooks in a number of schools across the UK to provide more healthy, nutritious school meal options. Although there was initial resistance from some teenagers and parents, the campaign was generally hailed as (±»ÔÞΪ) a huge success and helped to influence governmental policy on nutritional standards for school meals.
　　No one expects to end the teenage love affair with fast and junk food but, hopefully, if projects like ¡°Feed Me Better¡± and the Government¡¯s own ¡°Change 4 Life¡± campaign continue to give out the right messages, more young people will understand the importance of balancing occasional treats with healthier food options.
