20．Innocent Fast Food Restaurant
A study by academics from the University of California and Northwestern University claimed that"the causal link between the consumption of restaurant foods and obesity （肥胖） is minimal at best．"
It argued that a tax on high-calorie （卡路里） food，（33）whichwas proposed by many health campaigners in the US and Britain，might therefore not be an effective way for governments to deal with the problem．
It analyzed data on calorie intake around the country，which （34）had been collected（collect） before under the leadership of the US Department of Agriculture．The study found that people living closer （35）torestaurants were not significantly more likely to be obese than people living further away，（36）indicating（indicate） that easy access to restaurants had little effect．
It also showed that while restaurant meals typically held more calories than home-produced food，many customers often make up for this by eating （37）less（little） throughout the rest of the day．
"Obese people who ate at restaurants，"the study indicated，"also eat more when they eat at home．"
The US government estimates （38）thatabout one in three Americans，or 100 million in total，are obese．Last month it was predicted that 75 percent of Americans would be overweight in 2020．
The problem is thought to cost Americans between 150billionand170 billion in annual medical costs．
"While taxing restaurant meals might means （39）changing（change） where these consumers eat，"the study's authors，Michael Anderson and David Matsa，wrote，"our study results suggest that a tax （40）wouldbe unlikely to affect their potential tendency to overeat．"
