Recently, researchers from UT Health San Antonio's Biggs Institute for Alzheimer's & Neurodegenerative Diseases and other brain research

institutions examined middle-aged adults' cognitive markers of brain aging and red blood cell omega-3 fatty acid concentrations. In 2022,

Neurology published their study of 2,183 brain-healthy Framingham Heart Study Third-Generation and Omni 2 participants.

The researchers examined patients' blood levels of EPA and DHA, long-chain omega-3 polyunsaturated fatty acids found in oily fish. They then

measured subjects' total gray matter, hippocampus, and white matter volumes using brain MRIs. Higher omega-3 concentrations were linked to greater brain

According to the study, fish oil may protect carriers of APOE e4, a gene mutation that increases Alzheimer's risk. APOE-e4 carriers with higher DHA
