But the eventual effect on kids' diets was not good．Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained （节制）．They also consumed less fiber, iron and vitamin B．

One silver lining: Vending machine customers ate 4% less sodium （钠） than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines．That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty．In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic．Even for adults, the government recommends a daily limit of 2,300 mg．

Overall, vending machines in school appear to be a threat to children's health．The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year．For some students this might be a serious contributor to weight issues．The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was

conducted by the U．S．Department of Agriculture's Food and Nutrition Service．

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．

Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.

Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．

Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．

More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．

Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．
