«Steckel has found that Americans lose the most height to Northern Europeans in infancy and adolescence, which implicates pre- and post-natal care and teen-age eating habits. “If these snack foods are crowding out fruits and vegetables, then we may not be getting the micronutrients we need,” he says. In a recent British study, one group of schoolchildren was given hamburgers, French fries, and other familiar lunch foods; the other was fed nineteen-forties-style wartime rations such as boiled cabbage and corned beef. Within eight weeks, the children on the rations were both taller and slimmer than the ones on a regular diet.»
