It’s the season to talk about the much publicized turkey nap - caused by the evil Tryptophan!

Most interesting to me is that during the other 11 months of the year you don’t hear anyone talk about needing a nap after eating a turkey sandwich…..hmmmm wonder why?

--------------------------------------


A small bit of science- tryptophan is an amino acid that can have effects on relaxation. Tryptophan helps the body produce the b- vitamin niacin, which, in turn, helps the body produce serotonin, a chemical that acts as a calming agent in the brain and plays a key role in sleep. – ok enough science.

FYI - Other foods that are considered sources of tryptophan are dairy products, beef, poultry, barley, brown rice, fish, soybeans, and peanuts. - Do you need a nap after these?

-------------------------------------

Here are 5 reasons you may feel sleepy after a big holiday meal;

Heavy Carbohydrates – A heavy carbohydrate meal will increase insulin levels, which lowers competing amino acid levels in blood, creating an increase in the relative level of tryptophan in the blood. Serotonin may then produce a sleepy feeling.

Fatty food – A meal rich in fats slows down the digestive system and requires lots of energy to digest. Blood flow is redirected to your stomach rather than the rest of your body, leaving you with less energy overall.

Alcohol - Alcohol is a central nervous system depressant. A few drinks as part of the holiday celebration can add to the nap-factor. (Too many can add to the lampshade on your head factor)

Overeating -Your body requires a great deal of energy to digest a large meal (particularly high fat and high carbohydrates). When your stomach is full, blood is directed away from other organ systems, including your nervous system. And of course you know by now…you will feel the need to snooze.

R&R - Often the most relaxing part of the festivities is likely to be the meal. No matter what you may have been doing throughout the day, Thanksgiving dinner provides an opportunity to sit back and relax – followed by a big meal…. guess what? zzzzzzzzzzzzzzzzzz

A couple of quick tips to keep your energy levels up:

1) Snack on the fruits and vegetables (minimal dip) to keep calorie count down.
2) Eat a balanced turkey dinner - balance turkey or protein, a good helping of veggies and smaller servings of potatoes, breads etc.
3) Reasonable serving sizes - Eat one plate of food and be finished. Try everything but keep the servings sizes of heavy carb and fat foods small.
4) Beverages – be aware of high calorie celebratory drinks – especially alcohol. Have a couple for the entire day.
5) Exercise – get a workout in before your festivities to increase your metabolism and burn calories – a great healthy start.

Most of all – enjoy your time with friends and family. We all have so much to be thankful for – stop and take a minute with your family to be thankful.

I am thankful for all of you!

Happy Thanksgiving.
