When You Eat Turkey Does The Tryptophan Really Make You Tired?


Or do you not consume enough and it’s all in your head? Ate at a restaurant tonight that had turkey and dressing on the menu and thought it would. Anybody know facts?

    Turkey does contain tryptophan, an amino acid which is a natural sedative. But tryptophan doesn’t act on the brain unless it is taken on an empty stomach with no protein present, and the amount gobbled even during a holiday feast is generally too small to have an appreciable effect. That lazy, lethargic feeling so many are overcome by at the conclusion of a festive season meal is most likely due to the combination of drinking alcohol and overeating a carbohydrate-rich repast, as well as some other factors: Two other factors that contribute to the desire to sleep at the dinner table are meal composition and increased blood flow to the gastrointestinal tract. Studies have shown that a solid-food meal resulted in faster fatigue onset than a liquid diet. The solid-food meal also causes a variety of substances to jump into action that ultimately leads to increased blood flow to the abdomen. This increase in blood flow and an increase in the metabolic rate for digestion can contribute to the “coma.”1
    Those who still feel wary of turkey’s purported sleep-inducing properties should find solace in the knowledge that many items we eat contain tryptophan. Milk, beef, and beans are among the foodstuffs which house this amino acid, and experts say the average serving of chicken or ground beef contains as much tryptophan as a serving of turkey does.

    You would have to eat 2 large turkeys for it to affect you.
