Olive oil helps memory, says study
A Mediterranean diet with additional olive oil or nuts may improve thinking and memory in older adults, research suggests. Scientists looked at the effects of different kinds of diet in 334 men and women whose average age was around 67. Compared with a low-fat diet, a Mediterranean diet supplemented with nuts was associated with improvements in memory.
Adding extra olive oil to a Mediterranean diet appeared to improve thinking ability involving the brain's frontal lobes. However, Alzheimer's Research UK pointed out that the effects were very subtle and more work was needed before any conclusions could be drawn.
