Math, reading and science scores better in schools that subsidized morning meals.

Free school breakfasts may help low-income students do better in the classroom, a new study suggests. Students at elementary schools that offered free breakfast had 25 percent better math grades, and similarly higher reading and science grades, than students at schools without free breakfast. However, although the researchers found a link between schools that provide free morning meals and higher school performance, the study wasn’t designed to prove a cause-and-effect relationship.
