A bowl of soup a day could keep the pounds at bay. Health experts have discovered that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight. Because you tend to feel full sooner, you eat less of your main course. The soup method was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls. They found that when participants in the study ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup. But those who favour creamy soups should beware. Researchers stressed the soup must be low-calorie and based on stock, not cream. All of the soups tested in the study were made from the same elements—chicken stock (原汁鸡汤), broccoli (菜花), potato, cauliflower (花椰菜) and carrots. They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed (蔬菜泥) soup. Scientists thought that thick soups with thick pieces of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect. The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part funded by the National Institutes of Health. 小题1:The passage mainly discusses _____.
