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:

What else can we do to protect our newborns? See:

• How Fast Can Children Detoxify from PCBs? (http://nutritionfacts.org/video/how-f...)
• The Wrong Way to Detox (http://nutritionfacts.org/video/the-w...)
• Diet Soda and Preterm Birth (http://nutritionfacts.org/video/diet-...)
• Meat Fumes: Dietary Secondhand Smoke (http://nutritionfacts.org/video/meat-...)

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/mercu...).
