Omega-3s protect against brain injury and preserve nerve fibers
Omega-3s in high concentrations have a protective effect on the brains of the elderly. High levels of DHA (docosahexanoic acid), EPA (eicosapentaenoic acid) and DPA (docosapentaenoic acid) appear to reduce the risk of silent strokes, small lesions caused by lack of blood flow, and confer greater stability to the nerve fibers that make up the white matter.
