Eating an apple a day doesn&39; t keep the doctor away, but it does reduce the amount of trips you make to the drug store per year. That &39; s according to a new study that investigates whether there&39; s any truth in the old saying.
A team of researchers led by Dr Matthew Davis, of the University of Michigan School of Nursing,asked 8,399 participants to answer survey questions about diet and health. A total of 753 were apple eaters, consuming at least 149g of raw apple per day. The remaining 7, 646 were classed as non-apple eaters. When both groups answered questions on trips to the doctor and trips to the drug store per year,the apple eaters were found to be 27% less likely to visit the druggist for drugs.
Trips to the doctor were not significantly affected by apple consumption, though. "Evidence does not support that an apple a day keeps the doctor away. However, the small number of US adults who eat an apple a day does appear to use fewer prescription medications," the study concludes.
Apple eaters were also found to be less likely to smoke and be more likely to have a higher educational attainment than non-apple eaters. While apples do not compete with oranges, they docontain some immune (免疫的) system-increasing vitamin C, which may be why apple-eaters visit the druggist less. With over 8mg of vitamin C per medium-sized fruit, an apple can provide roughly 14% your daily recommended intake.
Previous studies have also linked apple consumption to a lower risk of Type 2 diabetes (二型糖尿病) ,improved lung function and a lower risk of colon (结肠) cancer.

Passage Two
America put more people in prison in the 1990s than in any decade in its history. That started a debate over the wisdom of spending billions of dollars to keep nearly 2 million people locked up. According to statistics, the United States ends 1999 with 1983084 men and women in prisons. That shows an increase of nearly 840,000 prisoners during the 1990s and makes the United States the country with the highest prisoner population in the world. With the cost of housing a prisoner at about $20,000 a year the cost in 1999 for keeping all these prisoners behind bars is about $39 billion.
Some experts argue that the money is well spent, saying the cost of keeping prisoners behind bars doesn't seem much in comparison in the 1990s coincided with (与……相一致) a steady drop in the US crime rates.
