Nowadays more and more people in the world are getting fatter, which troubles them a lot. In the past 25 years, the number of the people with obesity (肥胖症) in Europe has doubled. Experts say that it has a lot to do with our eating habits. Our eating habits are very important for good health and a strong body. Most of us like eating sweets and ice cream better than meat and rice. Sweets and ice cream are not bad for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite (食欲). It"s important for us to eat our meal at the same time each day. When we feel worried or excited, we may not want to eat. A long time ago, in England, some judges often decided whether a man was tell-ing the truth by giving him some dry bread. If the man could not swallow (呑) the bread, it meant that he wasn"t telling the truth. A man who is worrying something has difficulty in swallowing anything dry, because he loses his appetite. | ||||||||||||||||||||||
