A study published in the Journal of the Pakistan Medical Association finds that increased fruit and vegetable consumption among school-age children may increase learning skills related to interacting with others, as identified in social cognitive theory.

Researchers divided 138 students into two groups, with one group consuming more fruits and vegetables than the other. After three months, the group on the healthier diet tested higher in social cognitive learning skills. They also scored better in self-efficacy (belief they could succeed) in difficult situations, social support and observational learning.
