NEW YORK — January 28, 2014 — Eating more fish can give you a bigger brain and also protect against diseases such as Alzheimer’s, a new study has claimed.
People with higher levels of the omega-3 fatty acids found in fish oil may have larger brain volumes in old age equivalent to preserving one to two years of brain health, according to the study.
Shrinking brain volume is a sign of Alzheimer’s disease as well as normal ageing, researchers said. For the study, the levels of omega-3 fatty acids in red blood cells were tested in 1,111 women who were part of the Women’s Health Initiative Memory Study.
Eight years later, when the women were an average age of 78, MRI scans were taken to measure their brain volume.
