TORONTO, May 8 -- Children who drink 100% fruit juices are no more likely to be overweight than kids who drink none, and juice drinkers get considerably more nutritional benefits, researchers reported. Action Points
Explain to parents that 100% fruit juice is a good source of beneficial nutrients and vitamins, and according to this study does not appear to contribute to childhood obesity.
This study was published as an abstract and presented at a conference. These data and conclusions should be considered to be preliminary until published in a peer-reviewed publication.
In fact, kids may not be getting enough pure juice in their diet, noted Carol E. O'Neil, Ph.D., of Louisiana State University in Baton Rouge, and colleagues, at the Pediatric Academic Societies meeting here.
"Even among the children who consumed the most juice, we found no association at all with the children being overweight or at risk for overweight," said co-author Theresa A. Nicklas, Dr.Ph., L.N.
One startling finding, said Dr. Nicklas: More than half of the children studied (57%) drank no juice at all.
In a study of dietary habits of more than 3,600 children, the investigators also found that children who drank juice took in less sodium, fats, and sugars than children who did not consume 100% juice.
Nor did drinking juice come at the expense of drinking milk, as some critics of childhood nutritional practices have warned might happen.
The investigators analyzed data from the National Health and Nutrition Examination Survey (NHANES) 1999 - 2002. The data contained information on the types and amounts of foods and beverages consumed by children ages two to 11, using a multi-pass 24-hour recall method.
In the analysis presented here, the authors calculated least square means and conducted logistic regression analyses adjusting for gender, age, ethnicity, and energy intake.
They found that the 3,618 children studied consumed an average of about 1/2 cup (4.1 ounces) of juice a day, translating into a mean of 58 calories, or 3.3% of their total daily energy intake.
Children who drank 100% juices had significantly higher intakes of energy, carbohydrate, fiber, vitamins C and B6, potassium, riboflavin, magnesium, iron and folate compared with kids who didn't drink juice. Juice drinkers also consumed more total servings of fruits and less sodium, fat, saturated fat, added fat, and added sugar.
Children who drank 12 ounces of juice or more a day (13 % of those studied) were no more likely to be overweight than their peers who drank less juice. And those two- to three-year-olds who drank the most juice were three times less likely to be overweight compared with children who drank no juice at all.
The authors also found that there were no significant differences in the mean levels or amounts of juice consumption for any of the physiologic weight measures studied (body mass index, waist circumference, tricep skinfold, and percentile of weight-for-age and z-scores), and there was no overall difference in the likelihood of being overweight.
The Dietary Guidelines for Americans, issued in 2005 by the Department of Health and Human Services and the Department of Agriculture noted that while whole fruit provides fiber, "the fruit juices most commonly consumed by older children and adults provide more vitamin C, folate, and potassium in portions usually consumed than do the commonly eaten fruits."
The guidelines recommended that at least one fruit serving in a daily diet come from 100% juice, noted Dr. Nicklas, a member of the guidelines advisory committee. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 PAS: Pure Fruit Juices Don't Make Kids Fat
PAS：纯果汁不会使孩子变胖 交流帖！ 拙见：
banquar战友提到：

while whole fruit provides fiber, "the fruit juices most commonly consumed by older children and adults provide more vitamin C, folate, and[color=red] potassium in portions usually consumed than do the commonly eaten fruits." （这里不好理解，请战友指教）
整个水果可为人体提供纤维，而“与普通的吃水果方式相比，年长儿童和成人最常饮用的果汁却可提供更多维生素C、叶酸和以？？形式存在的钾。” 谢谢panliaoming战友的热心解答！我本来是不太清楚in portions usually consumed 这个地方。不过现在仔细想想，我的理解跟您说的“人体所需的部分钾盐“又有些不同。句式是不是可以这样转换？
