hmm.. interesting.

Just found this:
The major source of omega-3 in the diet is fish, which can often be limited in the diet especially during pregnancy due to concerns about mercury content. To ensure an adequate intake of all types of omega-3 fatty acids, including DHA, EPA and alpha-linolenic acid, pregnant women should be encouraged to consume a variety of omega-3 rich foods. Such foods include fish, leafy green vegetables, some nuts and vegetables and omega-3 enrichedeggs. The recommended Adequate Intake (AI) for long chain omega-3 during pregnancy is115mg per day. A serve of regular eggs contains 40mg of long chain omega-3, which represents 35% of the daily AI.
It was actually on an Egg Nutrition site (it's an org.au so an official site, not just some brand of eggs rattling off benefits of eggs hehe) and it has quite a good Postion Statement for Professionals on eggs in pregnancy, mentioning all the essentials needed in pregnancy, folate, iron, omega3 etc etc. And eggs actually contain a lot of these! Very interesting!
