Ant writes "MSN Encarta has Columnist Martha Brockenbrough's article on the myths of this American holiday. From the article: 'A lot of what we know to be true about Thanksgiving really isn't. Determining exactly what did happen is difficult. For starters, we don't even know for certain if the Pilgrims served turkey, although it's a strong possibility.'" Additionally, maotx writes "Contrary to popular belief, turkey does not make you sleepy. While purified tryptophan is a mild sleep-inducing agent, there is not enough in turkey to have a sedative affect. And on top of that, turkey isn't even unusually high in tryptophan compared to other foods, such as beef or soybeans. So for those of us enjoying turkey today, bring on the turkey and have a Happy Thanksgiving!"
