SPONSORED: UT Health San Antonio found that eating cold-water fish and other sources of omega-3 fatty acids may preserve brain health in middle age.
Eating cold-water fish and other sources of omega-3 fatty acids may preserve brain health and enhance cognition in middle age, new evidence from The University of Texas Health Science Center at San Antonio indicates.
The 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.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.
Researchers used a technique called gas chromatography to measure docosahexaenoic acid and eicosapentaenoic acid concentrations from red blood cells. The omega-3 index was calculated as DHA plus EPA.Success! You're on the list. The team divided participants into those who had very little omega-3 red blood cell concentration and those who had at least a little and more. “We saw the worst outcomes in the people who had the lowest consumption of omega-3s,” Satizabal said. “Although the more omega-3 the more benefits for the brain, you just need to eat some to see benefits.”
