Parents and doctors have the same worry over especially low birthweight newborns.__1__ A trend has therefore developed to make special formulas(配方)of extra nutrients and protein­rich foods for these tiny babies.Unfortunately，a British study has found that this practice could have negative long term effects，such as high blood pressure in adulthood.

Between 1993 and 1995，Atul Singhal of the Institute of Child Health and his colleagues researched 299 full­term newborns，each of whom weighed very little for their age.The babies' moms had decided not to breastfeed(用母乳喂养)．

　__2__ The rest received a formula with more nutrients and 28 percent more protein than the standard formula.The growth of all of these children was compared to that of 175 similarly low birthweight babies whose mothers had chosen to breastfeed their children for their first 9 months.__3__ They found 83 babies from the normal­formula group,70 babies from the extra­formula group，and 95 babies from the breast fed group.__4__ According to the latest data，children who had received the extra formula had significantly higher blood pressures than those in the other two groups.

Seven human test have indeed shown that when infants are overfed before being stopped breastfeeding，they have an increased possibility to become fat as youngsters.

No matter how big a child is at birth，he or she will probably reach the same adult height no matter how quickly the baby grows.But reaching one's adult size at a slow­to­moderate speed may have a lot of benefits，as Singhal says.__5__
