一项新研究揭示孩子吃的越好在学校表现更好
Alberta, Canada – March 20, 2008 – A new study in the Journal of School Health reveals that children with healthy diets perform better in school than children with unhealthy diets.
加拿大阿尔贝塔省，2008年3月20号，一项刊登于校园卫生杂志的新研究表明拥有健康饮食的孩子比饮食较差的孩子在学校成绩更好

Led by Paul J. Veugelers, MSc, PhD of the University of Alberta, researchers surveyed around 5000 Canadian fifth grade students and their parents as part of the Children’s Lifestyle and School-Performance Study.
此项研究由阿尔贝塔大学的理学硕士、公共卫生博士Paul J. Veugelers领导，研究者们调查了约5000名加拿大5年级学生及他们的家长作为儿童生活方式和学习成绩关系研究的一部分。
Information regarding dietary intake, height, and weight were recorded and the Diet Quality Index-International (DQI-I) was used to summarize overall diet quality. The DQI-I score ranges from 0 to 100, with higher scores indicating better diet quality. Less healthful dietary components included saturated fat and salt, while healthy foods were classified by fruits, vegetables, grains, dietary fiber, protein, calcium and moderate fat intake.
一些信息例如饮食摄入量、升高和体重等被记录下来，饮食质量国际标准指数（DQI-I）被用于概括所有孩子的饮食质量。这个指数分数从0到100，分数越高代表膳食质量越高。不健康的饮食成分包括饱和脂肪和盐，健康食物则归类为水果、蔬菜、谷物、膳食纤维、蛋白质、钙及适度的脂肪摄入。
A standardized literacy assessment was administered to the children. Multilevel regression methods were used to examine the association between indicators of diet quality and academic performance.
给这些孩子做一项标准化的读写能力测试。用多重回归的方法来检验饮食质量指数和测试成绩的关系
Students with an increased fruit and vegetable intake and less caloric intake from fat were significantly less likely to fail the literacy assessment. Relative to students in the group with the lowest DQI-I scores, students in the group with the best scores were 41 % less likely to fail the literacy assessment.
那些有较多水果蔬菜摄入和较少脂肪热量摄入的学生在读写能力测试中明显不容易出错。和那些最低DQI-I分数组的孩子相比，最高分数组的学生错误率要少41％。
“We demonstrated that above and beyond socioeconomic factors, diet quality is important to academic performance,” the authors conclude. “These findings support the broader implementation and investment in effective school nutrition programs that have the potential to improve student’s diet quality, academic performance, and, over the long term, their health.”
“我们证实除了社会经济因素以外，饮食质量对于学习成绩也很重要，”作者总结说,“这些发现为有效的校园营养计划的广泛实施和资金支持提供了帮助，而这些计划有可能改善学生的饮食质量和学习成绩，进而长期上对他们的健康有益。”
