| A new study suggests kids who eat nutritious foods might actually do better in school. After looking at surveys about the eating habits of more than 5,000 fifth-graders in Canada, researchers gave each child a standardized test. They found students who ate more fruits and vegetables and less fat were much less likely to fail the test. But it's hard to separate the possible effects of diet from other things that may affect kids' academic performance. For example, kids who had rich families tended to perform better on the tests, too. So, keep in mind that it might not be that eating better gave the kids an academic boost at all. It could be that parents who regularly feed their children healthy foods may also be more likely to spend extra quality time with their kids, and it can have an effect on kids' grades. |
