New evidence shows that for children younger than 24 months, drinking lots of fruit juice (果汁) can be harmful. The liquid fills their tiny stomachs and ruins their appetite (胃口)for foods with needed nutrients (营养物)and calories. According to a study published in Pediatrics(小儿科), the resulting malnutrition(营养不良)can prevent babies from developing normally.

Dr.Fima Lifshitz and a colleague at Maimonides Medical Center in Brooklyn, N.Y., examined eight children, ages 14 months to 27 months, whose growth had lagged behind their peers’. Each was drinking 12 to 30 ounces of juice a day. After recording what else the children ate, researchers realized that the fruit beverages(饮料)accounted for 25 to 60 percent of the daily calorie consumption (热能消耗量). Soon after parents gave their children less juice and more milk, the children gained weight.

Health professionals say babies under six months shouldn’t drink juice; some pediatricians (儿科医师)suggest waiting until after the first birthday. Whenever they start, young children shouldn’t have more than a few ounces a day.

“It hurt me more than you,” and “This is for your own good.” These are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.

That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy on us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on holiday.

Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake. One such teacher is Sharon Klompus who says of her students---“so inactive”---and wonders what happened. Nothing was demanded of them, she believes. Television, says Klompus, leads to children’s inactivity. “We’re not training kids to work any more,” says Kolmpus. “We’re talking about a generation of kids who have never been hurt or hungry. They have learned somebody will always do it for them. Instead of saying ‘go look it up’, you tell them the answer, it takes greater energy to say no to a kid.”

Yes, it does. It takes energy and it takes work. It’s time for parents to end their holiday and come back to work. It’s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it’s for their own good. It’s time to start telling them ‘no’ again.
