Omega-3s preserve brain size

The brain shrinks with age and also in Alzheimer’s disease.

In this study, doctors measured the omega-3s EPA and DHA in 1,111 older women, and followed up for eight years. Women with higher levels of omega-3s had larger brain volume overall, particularly in the hippocampus, the centrally located part of the brain that plays an important role in memory, and is where brain atrophy begins before signs of Alzheimer’s disease emerge.

Adding omega-3s through diet and supplements may potentially delay the normal loss of brain cells by one or two years, doctors said.
