More “Turkey Day” Trivia: Thanksgiving dinner

Turkey meat:  white vs. dark - What causes the color difference between white and dark turkey meat? The type of muscle fiber determines the color of the meat. Dark turkey meat has slow contraction muscle fibers. Slow contraction muscle fibers, sometimes called slow twitch muscle fibers, are used for extended muscle contraction in endurance activities and are supplied with lots of blood vessels, mitochondria, and myoglobin pigments, which give the red color to the meat. White turkey meat, on the other hand, has fast twitch muscle fibers for short bursts of strength and speed. Fast twitch fibers have a poorer blood supply, and fewer mitochondria and myoglobin, and tire quickly.

Cranberries – Of all fresh fruits, cranberries contain the most phenols, a type of disease-fighting antioxidant. Phenols and polyphenols are strong antioxidants and many scientists believe antioxidants protect the heart.

Yams vs. sweet potatoes - A yam is not the same thing as a sweet potato. Although yams and sweet potatoes are both angiosperms (flowering plants), they are not related botanically. Yams, native to Africa and Asia, are a monocot (a plant having one embryonic seed leaf) and are related to lilies and grasses. Sweet Potatoes are a dicot (a plant having two embryonic seed leaves) and are in the morning glory family. Yams are starchier and dryer than sweet potatoes.

Pumpkin pie - Most pumpkin fillings are really custard-type fillings with eggs acting as "gelling agents". They're able to do this because proteins in the eggs unwind as they are beaten and hold the pumpkin and liquids in a gentle mesh. As it cooks, it coagulates or sets and forms a custard-like filling. If the filling is cooked too long, the protein network contracts and shrinks, causing the filling to crack across the top. To prevent the cracking, cook it a little less this year. Remove it from the oven while the center still jiggles slightly if you give it a gentle shake. It may look like it still needs a little more cooking, but remember because of latent heat, it will continue to cook after it is removed from the oven.

Want to wow your guests at the Thanksgiving dinner table with your incredible knowledge of turkey trivia?  Check out these "Turkey Day" facts! 

• Most farm raised turkeys are White Hollands. They cannot fly.
• An adult turkey has about 3500 feathers. Big Bird’s costume (from Sesame Street) was made from nearly 4000 white turkey feathers, dyed yellow.
• Wild turkeys can glide almost a mile without flapping their wings. Over short distances, they can fly 55 mph and run 20 mph.
• Acorns are the wild turkeys’ favorite food. Because they have a poor sense of taste and smell, they choose acorns by size and shape.
• A turkey’s head will change colors when it’s excited.
• Wild turkeys spend the night in trees.
• A male turkey is called a tom, the female is called a hen and the babies, poults. Immature turkeys are called jake (male) and jenny (female).
• How to tell toms from hens:
• Toms are larger, have longer legs and bigger heads. Their wattle (growth under the chin) and snood (fleshy growth over the bill) are also longer.
• Toms grow a beard – long black feathers on their chest. The beard grows about 4 inches per year and keeps growing throughout their lifetime. Eventually, it drags the ground.
• Male turkeys gobble and females make a clucking sound.
• During mating season, a male turkey gobbles loudly and struts around, puffing out his chest, fanning his large tail and dragging his wingtips on the ground. 
• As male turkeys get older, they fight a lot and may attack humans. 
• About 180,000 wild turkeys live in Virginia, most of them in the Tidewater, South Mountain and South Piedmont regions.

Turkey daze...

Do you fall into a satiated stupor after Thanksgiving dinner? Have you heard that eating turkey makes you sleepy? Turkey contains tryptophan, an amino acid often blamed for the post-meal lethargy. The human body uses tryptophan to make serotonin. Studies have shown that serotonin, a type of neurotransmitter, induces sleep in nonhuman mammals and scientists believe it may do the same in humans. But don’t blame the turkey for your drowsy state. To enter the brain, tryptophan must hitch a ride through the blood-brain barrier on specialized protein transporters. Turkey contains five other amino acids in addition to tryptophan, all vying for a ride. Since tryptophan is the scarcest of the amino acids in turkey, it usually loses out in the competition.
What probably makes you sleepy after Thanksgiving dinner is dessert. Carbohydrates increase brain serotonin even though carbs contain no tryptophan. Here’s how: sweet desserts trigger your pancreas to produce insulin, a hormone that helps cells absorb glucose and amino acids. Insulin has little effect on tryptophan, but it does allow your cells to absorb other amino acids. With the others out of the way, tryptophan catches a ride into the brain and steps up the brain’s production of serotonin. Hence, the urge to snooze…
Even in the absence of dessert, you may find yourself nodding off after Thanksgiving dinner. Loading the stomach with food stretches the small intestine, causing sleepiness. All that blood going to the stomach and intestines means less blood for the brain and muscles. And then there are the beverages. Do you enjoy wine or beer with your meal? Drinks containing alcohol can also cause drowsiness. So enjoy Thanksgiving dinner but please don’t blame the bird for your turkey daze!
