Eating habits linked to academic performance
Junk food associated with poorer academic achievement
An analysis of more than 850 elementary school children found those who reported higher consumption of snack foods and sugar-sweetened beverages scored lower on standardized academic tests, on average, than children who consumed less of these foods. While unhealthful diets were not linked to lower cognitive test scores, the findings suggest policies to improve children's diets could help kids do better in school, researchers say.
Hydration associated with better brain functioning
Epidemiological data suggests many children in the United States do not drink enough water. In a new study, researchers found children with greater habitual hydration performed better during tasks requiring cognitive flexibility. In addition, children showed improvements in their hydration levels and working memory after consuming a higher amount of water--2.5 liters daily--than when instructed to drink just half a liter per day, suggesting increasing water intake can help improve both hydration and cognitive function.
