Happy Turkey Day Ladies and Gents!!

Give thanks in all things…

Have a blessed holiday people!

Don’t eat too much turkey… it’ll just make you sleepy.

Remember, wherever you go… there ya’ be!

I’m outta here! Homeward bound! :agree:


Happy TG to all also (well, at least to the Americans, err Statesmen,

Tryptophan, here I come. :)

I thought mythbusters busted that one?

Happy Thanksgiving to all too!

Turkey meat and drowsiness from daWiki.

One widely-held belief is that heavy consumption of turkey meat (as for example in a Thanksgiving or Christmas 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. Furthermore, postprandial Thanksgiving sedation may have more to do with what is consumed along with the turkey, in particular carbohydrates and alcohol, rather than the turkey itself. This is demonstrated in a popular episode of the sitcom “Seinfeld” when characters of the show drug a woman using turkey and alcohol in order to play with her toy collection.

It has been demonstrated in both animal models and in humans that ingestion of a meal rich in carbohydrates triggers release of insulin. Insulin in turn stimulates the uptake of large neutral branched-chain amino acids (LNAA) but not tryptophan (trp) into muscle, increasing the ratio of trp to LNAA in the blood stream. The resulting increased ratio of tryptophan to large neutral amino acids in the blood reduces competition at the large neutral amino acid transporter resulting in the uptake of tryptophan across the blood-brain barrier into the central nervous system (CNS). Once inside the CNS, tryptophan is converted into serotonin in the raphe nuclei by the normal enzymatic pathway. The resultant serotonin is further metabolised into melatonin by the pineal gland. Hence, these data suggest that “feast-induced drowsiness,” and in particular, the common post-Christmas and American post-Thanksgiving dinner drowsiness, may be the result of a heavy meal rich in carbohydrates which, via an indirect mechanism, increases the production of sleep-promoting melatonin in the brain. Well at least if you have a brain.


pineal gland

the wife doesn't let me take that out of the house, so i'm not sure if any of that applies to me.

i love sleep!

Happy T-Day everyone! (North AMERICAN, U.S. citizens that is) :laugh:
