Could eating salmon, cod, tuna, herring, or sardines keep your brain healthy and your thinking agile in middle age? This study says emphatically, YES.
Eating cold-water fish and other sources of omega-3 fatty acids may preserve brain health and enhance cognition in middle age, according to new evidence from the University of Texas Health Science Center at San Antonio.
In fact, healthy volunteers whose red blood cells contained higher concentrations of omega-3 fatty acids were found to have better brain structure and cognitive function than others who were aged 40-60.

In fact, healthy volunteers whose red blood cells contained higher concentrations of omega-3 fatty acids were found to have better brain structure and cognitive function than others who were aged 40-60.
Volunteers’ average age was 46. The team looked at the relation of red blood cell omega-3 fatty acid concentrations with MRI and cognitive markers of brain aging. Researchers also studied the effect of omega-3 red blood cell concentrations in volunteers who carried APOE4, a genetic variation linked to higher risk of Alzheimer’s disease.
The study of 2,183 dementia- and stroke-free participants found that higher omega-3 index was associated with larger hippocampal volumes. The hippocampus, a structure in the brain, plays a major role in learning and memory.
