问题 What you feed a newborn baby during the first week of life could be critical in deciding whether that baby grows up to be obese(肥胖的)，US researchers say．
    They found that formula—fed babies who gained weight rapidly during their first week of life were significantly more likely to be overweight decades later．It suggests that there may be a critical period in that first week during which the body’s physiology may be programmed to develop chronic disease(慢性病)throughout life．Our findings also point towards new potential targets for preventing obesity．If these results are confirmed by other studies，they may lead to interventions in newborns to help prevent long—term development of obesity．
    This team studied 653 white adults aged．20 to 32．They said each additional 100g of weight gained during the first eight days of life increased a baby’s risk of becoming an overweight adult by about 10 percent．The study also helps reinforce recommendations that mothers breast—feed their babies．For a variety of health reasons，the American Association of Paediatrics recommends exclusive breast—feeding during a baby’s first six months of life．Breast—fed babies are less likely to be overweight．In a special issue on obesity，the Heart Association said childhood obesity was such a critical public health problem that it could reverse the gains made over the last 50 years in reducing heart disease and death．
    An estimated 16 percent of US children are overweight and carry a significant risk of developing heart disease and diabetes while young adults．Only 64 percent of mothers initiate  breast—feeding，and only 29 percent of babies are still being breast—fed when they are six months of age．Rates of initiation and duration are even lower among African—American women．
    The Heart Association has called for a multi—pronged approach to preventing childhood obesity involving families，the health care system，private insurers，government agencies，schools and the food and entertainment industries．
The main idea of the passage is that_________．
选项 A、obesity may cause heart diseases and some other health problems
B、breast—feeding a newborn baby after its birth can prevent it from 1)eing ovel~eigh!
C、the number of the breast—fed babies is increasing
