Fatty Foods May Boost Memory

A hormone released during the digestion of certain fats triggers long-term memory formation in rats, a new study says.
Researchers found that administering a compound produced in the small intestine called oleoylethanolamide (OEA) to rats improved memory retention during two different tasks.

When cell receptors activated by OEA were blocked, the animals' performance decreased.

Though the study involved rats, OEA's effects should be similar in other animals, including humans, said study team member Daniele Piomelli, a neuroscientist at the University of California, Irvine.

Follow the Fat

The team suspects OEA's memory-enhancing activity likely evolved to help animals remember where and when they ate a fatty meal, so they could return to that spot later.
