'Bad' Fat May Hurt Brain Function Over Time

Women who eat a lot of "bad" saturated fat may hurt their overall brain function and memory over time, Harvard University researchers report.

In contrast, eating more "good" monounsaturated fat improved brain function and memory, suggesting that fats may have the same effect on the brain as they do on the heart, the researchers added.

"Making changes and substitutions in one's diet to eat fewer saturated fats and consume more monounsaturated fats might be a way to help prevent cognitive decline in older people," said lead researcher Dr. Olivia Okereke, an assistant professor of psychiatry at Harvard Medical School. "This is important because cognitive decline affects millions of older people. So, this is a promising area of research."
