FILE - In this Wednesday, Oct. 17, 2007 file photo, a person eats in London. Researchers at Oxford University and the University of Reading estimated a 20 percent tax on soft drinks in Britain would reduce sales by 15 percent and could cut the number of obese adults by about 180,000. Though the number works out to a modest drop of 1.3 percent in obesity, scientists say that reduction would still be worthwhile in the UK, which has a population of about 63 million and is the fattest country in Western Europe.
