David Warren's List: Kit's list

In the study, gerbils were given various combinations of three compounds needed for healthy brain membranes: choline, found in eggs; uridine monophosphate (UMP) found in beets; and docosahexaenoic acid (DHA), found in fish oils. Other gerbils were given none of these to serve as a baseline. Then they were checked for cognitive changes four weeks later.

The scientists found that the gerbils given choline with UMP and/or DHA showed cognitive improvements in tasks thought to be relevant to gerbils, such as navigating mazes.
