This Food May Help You Sleep Better: They found that eating fish regularly--the more, the better--led to better sleep and higher IQ scores.

Forget warm milk. A new study from the University of Pennsylvania says that fish may be the key to a good night's sleep," reported Time in December.

And it's not just sleep. "Eating fish just a few times a month may improve your brain functioning," one of the study's authors told Time.

What's the source of those rather extravagant promises?

"The researchers asked 541 schoolchildren in China between ages 9 and 11 to describe their eating habits, including how often they ate fish," explained Time. The parents answered questions about their kids' sleep. (1)

The study "found links between eating fish regularly--the more, the better--and both improved sleep and higher IQ scores," reported Time.

Hello? Could something else about the kids or parents have explained the higher IQs or (according to the parents) better sleep? The study took some things into account, but didn't even look at what else the children ate beyond fish.

Bottom Line: Preliminary studies like these only make headlines because we all want to sleep well and stay sharp.
