Fish oil can increase brain size: study

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.

Those with higher levels of omega-3s had larger total brain volumes eight years later. Those with twice as high levels of fatty acids (7.5 vs 3.4 per cent) had a 0.7 per cent larger brain volume.

"These higher levels of fatty acids can be achieved through diet and the use of supplements, and the results suggest that the effect on brain volume is the equivalent of delaying the normal loss of brain cells that comes with ageing by one to two years," said study author James V Pottala, from the University of South Dakota in Sioux Falls.

Those with higher levels of omega-3s also had a 2.7 per cent larger volume in the hippocampus area of the brain, which plays an important role in memory.

In Alzheimer's disease, the hippocampus begins to atrophy even before symptoms appear.
The study was published in Neurology, the medical journal of the American Academy of Neurology.
