Tryptophan In Turkey Is Not What Makes You Sleepy
There are many myths surrounding the essential amino acid tryptophan and Thanksgiving dinner. When tryptophan is taken on its own at certain doses on an empty stomach, it can make you sleepy. However, the tryptophan levels in turkey are not what is causing post-meal drowsiness—sleepiness after Thanksgiving dinner is due to the huge quantity of carbohydrates your body received in a single sitting. When you overeat, your body diverts blood to your stomach and the rest of the digestive system to handle the overload. Most American consumes as many or more calories during Thanksgiving dinner than in a single normal day. In addition, there are lower levels of tryptophan in turkey than in chicken.
