the truth about the correlation between eating Turkey and sleep, you may not
feel as tired tomorrow after you eat that enormous Thanksgiving Dinner? :)
lol Tara, wish, I could be there with the entire Family at your house.
However, Darrell and I will see you all in a month. For now, read the below
article. It has been along day at work and I have another 3 days before I
may be off.I will try and write a KDD in the next day or so. Until then,
Enjoy the Holiday and the poems I have posted from nethugs.com. None of
them I created. I wish, I were that talented. Take care and stay well.
Tryptophan & Carbohydrate Chemistry
Unless a microwave dinner is your idea of a Thanksgiving feast, you probably
have had firsthand experience with the after-dinner fatigue that sets in
after
the meal. Why do you want a nap? To escape the dishes? Perhaps, but the meal
itself plays a big part in the way you feel.
. L-Tryptophan and the Turkey
The turkey is often cited as the culprit in afterdinner lethargy, but the
truth is that you could omit the bird altogether and still feel the effects
of
the feast. Turkey does contain L-tryptophan, an essential amino acid with a
documented sleep inducing effect. L-tryptophan is used in the body to
produce
the B-vitamin, niacin. Niacin, in turn, is used to produce serotonin, a
neurotransmitter that exerts a calming effect and regulates sleep. However,
L-tryptophan
needs to be taken on an empty stomach and without any other amino acids or
protein in order to make you drowsy.

There's lots of protein in a serving of turkey and it's probably not the
only food on the table.
It's worth noting that other foods contain as much or more tryptophan than
turkey (0.333 g of tryptophan per 100 gram edible portion), including
chicken
(0.292 g of tryptophan per 100 gram edible portion), pork, and cheese. As
with turkey, other amino acids are present in these foods besides
tryptophan,
so they don't make you sleepy.
. L-Tryptophan and Carbohydrates
L-tryptophan
may be found in turkey and other dietary proteins, but it's actually a
carbohydrate-rich (as opposed to protein-rich) meal that increases the level
of this
amino acid in the brain and leads to serotonin synthesis. Carbohydrates
stimulate the pancreas to secrete insulin. When this occurs, some amino
acids that
compete with tryptophan leave the bloodstream and enter muscle cells. This
causes an increase in the relative concentration of tryptophan in the
bloodstream.
Serotonin is synthesized and you feel that familiar sleepy feeling.
. Fats
Fats slow down the digestive system, giving Thanksgiving dinner plenty of
time to take effect. Fats also take a lot of energy to digest, so the body
will
redirect blood to your digestive system to tackle the job. Since you have
less bloodflow elsewhere, you will feel less energetic after eating a meal
rich
in fats.
. Alcohol
Alcohol is a central nervous system depressant. If alcoholic beverages are
part of the holiday celebration, then they will add to the nap-factor.
. Overeating
It takes a great deal of energy to digest a large meal. When your stomach is
full, blood is directed away from other organ systems, including your
nervous
system. The result? You will feel the need to snooze after any big meal,
particularly if it is high in fats and carbohydrates.
. Relaxation
Although many people find the holidays stressful, the most relaxing part of
the festivities is likely to be the meal. No matter what you may have been
doing
throughout the day, Thanksgiving dinner provides an opportunity to sit back
and relax -- a feeling that can carry over after the meal.
list end
and celebratory atmosphere. Happy Thanksgiving!
