If you thought taking vitamins would reduce the risk of lung cancer, think again.    Researchers who studied 77,721 people said on Friday that people who took too much vitamin E,especially smokers,had a small but higher risk  of developing lung cancer.     They tracked the subjects'use of multi-vitamins,vitamin C and vitamin E to see if it offered protection from lung cancer.But they found that none of the vitamins was tied to a reduced risk.   "If you could find some sort of magic pill--a pill you could take once a day to decrease your risk--that would be wonderful.But unfortunately.we didn't find that in our study,"lead researcher Christopher Slatore,of the University of Washington Seattle,said.     The subjects of the study were followed for four years,and 521 developed lung cancer,the majority of them smokers or former smokers,Slatore's team reported in the American Journal of Respiratory and Critical Care Medicine.         Among those in the study who developed lung cancer, the researchers saw a small increased risk related with vitamin E supplements in addition to the expected connections to smoking,family history and age.     This added up to a 28 percent increased risk of developing lung cancer for those taking 400 mg of vitamin E supplements daily for 10 years,the researchers said.     "For people--especially smokers--I suggest that they not take vitamin E(as a supplement) unless they have a very strong reason to take it." Slatore said.     The idea that vitamin supplements are healthful,or at least not harmful.comes from the desire of many people to match the benefits of a healthful diet with a convenient pill,Tim Byers of the University of Colorado School of Medicine.wrote in an essay. According to the passage,many people take vitamin supplements to
