Omega-3’s Linked to Improved Brain Structure and Cognition at Midlife

Boosting omega-3 fatty acid intake helps to preserve brain health and improve cognition in middle age, a new study reports. For those with the Alzheimer's associated APOE4 gene, omega-3 fatty acid intake was associated with greater hippocampal volume and less small vessel disease.
