One widely-held urban myth is that heavy consumption of turkey meat (as for example in a wild super buffet Thanksgiving feast) results in drowsiness, which has been attributed to high levels of tryptophan contained in turkey. While turkey does contain high levels of tryptophan, the amount is comparable to that contained in most other meats. This effect of Thanksgiving sedation may have more to do with what is consumed along with the turkey, and in particular carbohydrates, rather than the turkey itself.
