I like the advice at http://www.angelhealingcenter.com/An...atoryDiet.html , especially concerning fish oil. A Life Extension Foundation article at http://www.lef.org/magazine/mag2002/...2_awsi_03.html agrees with the advise on the first link, but isn't nearly as comprehensive.

If you haven't tried fish oil caps, it takes a while for your body to adapt. Try taking the capsule at the beginning of a meal, to keep the concentrated fish oil away from your esophagus. Believe me, you do not want to experience hours of fishy burps. It's funny to say, but a real bummer to experience. Eventually, your body adapts to the fish oil. I can now take a capsule on an empty stomach with no problem.
