A war on sugar has begun in the UK that echoes the nation"s successful campaign against salt. The effort is【C1】______because it could help to reduce obesity, but cutting sugar out of people"s diets poses【C2】______challenges. Last week, a group of academics and policy【C3】______specializing in medicine and【C4】______announced that they had formed a campaign group, Action on Sugar. Their idea is to convince manufacturers to【C5】______and gradually lower the【C6】______of sugar added to foods—so slowly that it isn"t missed by【C7】______. It is essentially the same【C8】______as a campaign that is【C9】______credited with reducing British people"s salt intake. Over the past decade, CASH, a non-government organisation, helped to create anti-salt【C10】______aimed at the general public,【C11】______year-by-year targets for companies to reduce salt levels. These were【C12】______but had the backing of the government, and it was【C13】______that the targets would be legally enforced if companies【C14】______. Most manufacturers lowered their salt levels —and,【C15】______, there has been a 15 per cent【C16】______in salt intake in the UK, according to CASH. Repeating the trick with sugar may be more【C17】______not least because we do not know for sure if our palates(sense of taste)can adjust to eating food that is less【C18】______. By contrast, studies have shown that if volunteers are forced to eat a less salty diet, over several weeks they gradually begin to【C19】______food that is less salty. "There"s no reason to think that would not hold【C20】______for sweet taste too," says Charles Spence, a neurogas-tronomist at the University of Oxford. 【C6】
