     A study published in September suggests there is a surprising way to get people to avoid unhealthy foods;

change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to

answer some questions on their personalities (个性) and food experiences. "One week later," Loftus says, "we

told those people we'd fed their answers into our smart computer and it came up with an account of their early

childhood experiences." Some accounts included one key additional detail (细节):"You got sick after eating

strawberry ice-cream." The researchers then changed this detail into a manufactured (人为促生的) memory

through leading questions－Who were you with? How did you feel? By the end of the study up to 41% of those

given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it. 

     When Loftus published her findings, she started getting calls from people begging her to make them

remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work

only for foods you don't eat on a regular basis. But most important, it is likely that false memories can be

implanted (灌输) only in people who are unaware of the mental control. And lying to a patient is immoral, even

if a doctor believes it's for the patient's benefit.

     Loftus says there's nothing to stop parents from trying it with their overweight children. "I say, wake up－

parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent

diseases caused by fatness and all the other problems that come with that, you might think that's a more moral

lie. Decide that for yourself."
