It’s commonly believed that a drug in turkey meat, tryptophan, causes sleepiness after eating. But because the tryptophan levels in turkey are no higher than in most other fowl, why don’t we feel just as tired after ingesting something as common as a chicken sandwich? The effect has everything to do with what else we eat.
Ingestion of a meal rich in carbohydrates triggers the release of insulin, which in turn stimulates the uptake of amino acids into muscle, inadvertently increasing the ratio of tryptophan in the blood stream. Nutritionist Randal Farmer continues:
“Christmas and Thanksgiving dinner drowsiness is the result of a heavy meal rich in carbohydrates which, via an indirect mechanism, increases the production of sleep-promoting melatonin in the brain.”
Without our system’s preoccupation with other matters tryptophan would have no impact. This same indirect causation has been theorized by some to be a likely trigger of the coming zombie pandemic.
If the necessary ingredients for zombieism are already lying dormant in human beings, then the next undead outbreak may simply require another agent to come along and launch the nightmare. A new strain of flu, bacterial outbreak from tainted food, or changes in environmental conditions may be what it takes to spark the end of the world.
More evidence that the zombie plague could strike at any time for any reason. So don’t eat too much this holiday season. You need to stay alert!
