NEW YORK (Reuters Health)—Kids who eat better perform better in school, a new study of Nova Scotia fifth?graders confirms.
Students who ate an adequate amount of fruit，vegetables，protein，fiber and other components of a healthy diet were significantly less likely to fail a
literacy test，Dr.Paul J．Veugelers of the University of Alberta in Edmonton and colleagues found.
While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate，they looked at 4, 589 fifth?graders participating in the Children's Lifestyle and School?performance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment.
The better a student's eating habits based on several measures of diet quality，including adequacy and variety, the less likely he or she was to have failed the test, the researchers found，even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test.
To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition(營養(yǎng)不良)．
“This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day，” the researchers conclude.
Another research from the UK is suggesting that children's diets in the pre?school years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets(塊) they ate at lunchtime.The researchers say they have found that children who ate a diet of “junk food” at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment.
