LIFE IS A JOURNEY, ARE YOU READY?

THAT TURKEY BREAST MADE ME SLEEP

We mentioned that we dozed off also immediately after eating our turkey main dish last friday. Some people said it is a myth, but we do not agree with it. They said people usually feel sleepy after a big meal. Our meal was not big. We have gotten quite good with our portions for degustations now. We didn't even manage to get to desserts!

THIS IS FROM LISTVERSE.COM :

The Myth : Eating turkey makes you sleepy because it contains tryptophan.

This is one of the most common myths on this list – and it pops up every year around Thanksgiving. But actually, chicken and ground beef contain almost identical quantities of tryptophan as turkey does. Other foods such as cheese and pork contain significantly more of the chemical than turkey. So why do people think turkey makes them sleepy? It is most likely due to turkey appearing at very large meals often eaten during the day rather than the evening. The heavy meal slows blood flow which can cause drowsiness, and the timing can have a huge psychological impact: in other words, you are imagining it.

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. Tryptophan also can be metabolized into serotonin and melatonin, neurotransmitters that exert 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 CarbohydratesL-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.

Let us know what you think. Truth or myth!
