Numerous studies have highlighted the link between whole, minimally processed foods and better academic performance. Adolescents who consume more produce, whole grains, and lean protein often fare better on standardized tests (Florence MD et al., J Sch Health. 2008). At the college and professional levels, a diet rich in omega-3 fatty acids and antioxidants (like those found in nuts, seeds, and certain fruits) can further boost mental clarity (Esteban-Cornejo I et al., Public Health Nutr. 2016).
