US researchers linked to Harvard University found older women who ate lots of food high in saturated fats had worse memories than others.
By contrast, those who ate more monounsaturated fats – found in olive oil, sunflower oil, seeds, nuts and avocados – had better memories.
Dr Oliva Okereke, from the Brigham and Women’s Hospital in Boston, Mass., which is affiliated to Harvard Medical School, said: “When looking at changes in cognitive function, what we found is that the total amount of fat intake did not really matter, but the type of fat did.”
