     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 regime 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 be careful. Researchers stressed the soup must be

low-calorie and based on stock(菜汤), not cream.

     All of the soups tested in the study were made from identical ingredients - chicken stock , broccoli

(硬花甘蓝), potato, cauliflower(菜花)and carrots.

     They were mixed together to create four different textures and thickness from separate stock and

vegetables through to pureed soup.

     Scientists thought that thick soups with chunks 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.
