If
you are following sound advice on how
to get a good night's sleep, but are still having trouble sleeping soundly,
you may want to try eating a bedtime snack that combines a concentrated dietary
source of tryptophan with a healthy carbohydrate-rich food.
Tryptophan
is an amino acid that your body cannot make; you must obtain it from the foods
that you eat. Once tryptophan crosses your blood-brain barrier to gain access
to your brain, it is used to make a hormone called serotonin.
Serotonin
acts within your body to promote feelings of sleepiness, calm, and relaxation.
Without
adequate levels of serotonin in your system, you will have a hard time feeling
sleepy enough to rest soundly. And without adequate levels of tryptophan within
your brain, you will not be able to produce significant amounts of serotonin.
The
challenge with shuttling tryptophan through to your brain is that it has to compete
with other amino acids for access to the limited number of channels that line
your blood-brain barrier. And tryptophan tends to be outnumbered by other amino
acids in natural foods.
The
key to getting enough tryptophan to your brain to sleep well at night is to combine
a tryptophan-rich food with a carbohydrate-rich food. This is because ingesting
a carbohydrate-rich food causes your body to release insulin, which diverts many
of your other amino acids away from your brain, leaving tryptophan with little
competition to cross your blood-brain barrier to gain access to your brain.
Here
is a list of some healthy foods that are naturally rich in tryptophan:
If
you combine any of the food listed above with a healthy carbohydrate-rich food
as an evening snack, you will provide your body with a good opportunity to produce
enough serotonin to facilitate a good night's rest.
What
follows are some suggestions for healthy meals and snacks that combine a tryptophan-rich
food with a carbohydrate-rich food:
Rice
with miso soup
Whole
grain pita with hummus (add tomato and red onion slices for flavor)
Whole
grain crackers with organic peanut butter (add a touch of honey for sweetness,
if desired)
Clearly,
the possible combinations of tryptophan-rich foods and carbohydrate-rich foods
are endless. Be creative and enjoy the process of figuring out which combinations
suit your palate and help you sleep like a bear.
Editor's
note: Do you have sleepless nights? Can't seem to turn your brain off, get
to sleep, or stay asleep?
If
you'd like to start getting consistently good nights of sleep, we have an audio
CD called NightTrain designed to help you
fall into a restful, continuous sleep.
Here's
what I experience with NightTrain: "The sleep I've been getting with NightTrain
has been so good that for the first time in my life the alarm clock actually rips
me out of sleep. Before I'd always been conscious in some form before it went
off. Now, thanks to NightTrain, I'm deep in REM or stage 3 or 4 sleep before the
alarm clock rings."

Reviews
Just a note to let you know how much I appreciate your
newsletter. As a fellow health care provider (optometrist) and medical researcher,
I find your distillation of the literature into lay terms to be accurate and very
understandable. I really enjoyed your contribution regarding macular degeneration.
Keep up the good work. - Kristine Erickson, OD, PhD,

Thanks for your excellent health newsletter. I look
forward to it every week. Thanks for providing the best online health resource
I have found. - Moorea Maguire
I'm sure as a doctor you hear
your share of complaints. I just thought you'd like to know that there's at least
one person in your "e-audience" that appreciates the time and effort you put into
sending the emails. I really look forward to them. - Linda H., Raleigh, North
Carolina
Many of my adult ESL students are Korean, and enjoy bits
and pieces from your newsletter that I have shared with them. In addition to your
logical approach to health, I enjoy sharing your newsletter because your English
is unfailingly correct as well as easily understood. Thank you for your beautiful
approach to life. - J. Zetterstrom
I thank you and your staff
for such a great website. I am former National Level Bodybuilder so I know a thing
or two about health and fitness. Your site is very valuable and I do my best to
pass it on to friends and people I train. It is also a helpful resource in my
career as a human service provider working with clients who need to recover from
substance abuse. I believe a major part of recovery is getting your body and mind
feeling healthy and strong. Thank you again! Great Website! - Michael Christopher,
MSW
I truly appreciate your wonderful newsletter - your balanced
and professional way of looking at issues is so helpful! - Erica H.
