DESCRIPTION: Exposure to mercury during pregnancy appears to influence fetal brain development as detected by decreased size of a newborn's brain.

I've covered mercury in fish before in videos such as Nerves of Mercury (file:///Users/MichaelGreger/Downloads/nutritionfacts.org/video/nerves-of-mercury/index.html), Hair Testing for Mercury Before Consider Pregnancy (file:///Users/MichaelGreger/Downloads/nutritionfacts.org/video/hair-testing-for-mercury-before-considering-pregnancy/index.html), and Fish Fog (file:///Users/MichaelGreger/Downloads/nutritionfacts.org/video/fish-fog/index.html). For more on canned tuna in particular, check out:

But what about the long chain omega-3 DHA in fish—isn't that necessary for healthy brain development? That's the topic of my next video, Mercury vs. Omega-3s for Brain Development (http://nutritionfacts.org/video/mercury-vs-omega-3s-for-brain-development).

Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/fish-consumption-associated-with-brain-shrinkage/ and he'll try to answer it!
