Turkey Myth Debunked

Myth: Eating turkey makes you sleepy.

Thanksgiving is the official holiday you load yourself up with a competitive eater's portion of hot, steamy bird meat and a myriad of other treats. Many believe your fragile body is no match for the turkey's almighty tryptophan, a sedative so powerful that you wind up falling asleep before halftime of the football game.

According to nutritionists, food science researchers, and people who are not your grandparents, turkey is not a sedative. It is true that turkey has tryptophan (an amino acid that eventually becomes serotonin and melatonin; neurochemicals which play a role in getting your brain to fall asleep).

However, turkey does not contain enough tryptophan to have any noticeable effect on your state of consciousness. In fact, it has exactly as much tryptophan as other dairy, nut, and meat products do. In fact, cheddar cheese contains more tryptophan than turkey.

The main reason you pass out on the couch after the great meal and conversation is the fact that you ate, on average 4,500 calories or more. You pass out because your body is working overtime, struggling to digest all the meat, dressing, bread, desert, and other goodies you just consumed. A few pre and post meal alcoholic beverages also add to the mix, increasing the desire to share a comfortable nap with family.

Incidentally, when it comes to drinking that warm glass of milk, there are no natural sedatives at play either. It is simply very soothing to slowly drink a warm liquid causing a completely calming reaction.

Cranberry Juice Myth

Contrary to popular belief, the cranberry juice commonly found on grocery store shelves is ineffective at preventing urinary tract infections.

Cranberries do contain compounds that defend against bacterial infection in the bladder wall, which can help prevent UTIs, but cranberry juice does not have a high enough concentration of these compounds to do much good. In order for a noticeable reduction in bacterial adhesion, a person would have to consume at least 32 ounces of cranberry juice daily.

Cooking Steak Myths

Myth Searing steaks lock in juices. - First, it helps give you a nice crunchy and flavorful snap when you take a bite and you can get a prettier color on the outside. However, it does not lock in juices.

Myth Salting your steak before cooking will draw out the moisture and leave you with a tough cut of meat. - Yes and no. It is true, if you are going to salt-pack a steak for an extended period of time, the salt will most definitely draw out the moisture. The way to prepare a steak for grilling is to pat a nice solid coat of sea salt and crushed pepper on the exterior right before placing it over the heat. There is not enough time for the salt to draw out any moisture and you are left with a well-seasoned, great-tasting cut of meat.

Myth Only flip your steak once.- If you flip your steak more than once you are not ruining it. This is simply a matter of personal preference. The effect on your steak's taste is negligible. It is more about how you prefer to grill, and where you are most comfortable. If you are regularly flipping your steak, chances are you have the hood open, which means you are letting out heat. This will affect the timeliness of your cook, but if you make an adjustment for the lower temperature by extending time, it will be fine. Some people prefer to flip their steaks often, because it helps prevent curling.

Myth Sizzling steaks hot of the grill taste best. - While setting your steak out on the counter for 20 to 30 minutes before cooking it is a misconception, resting your steak after cooking is not. You should not go straight from grill grate to plate. Resting your steak for five minutes after coming off the grill will make it juicier and more flavorful. Basically, there is much science that goes into this. When a steak comes hot off the grill the exterior is very hot, and there is little moisture. The center of the steak is considerably cooler and still has moisture. As a steak rests, the muscle fibers loosen and the juices will spread more evenly across the steak.

Ostriches Bury Their Heads Myth Debunked

This is one of those myths that is accepted as fact without question. People generally believe this is something the birds do when danger is near.

Ostriches do run if they feel that danger is approaching, but they also have a powerful kick to defend themselves. Ostriches may hold their heads low in an attempt to be harder to see, but they do not actually bury their heads.

Myth: Earth is Close to Overpopulation

This is a myth has been around since the 18th century, but the world is a really big place with plenty of space.

Let's look at how much land it really takes to hold 6 billion people. To give you an idea, consider the small nation of Japan, which has about 143,000 square miles of land. One square mile has 27.9 million square feet. Japan has a total of about 4 trillion square feet, enough to give each person on earth 670 square feet. If we housed people in families of four in simple two-level buildings (8 people per building, one family of four per level), each building could be on a lot of over 5300 square feet.

Using the American average of 8,000 square feet to house four people, the entire population of the planet would fit into a space the size of Texas and Nevada combined or less than the state of Alaska. That leaves a bunch of unused space for growing crops, sailing, and going on vacations.

Touching Birds and Eggs Myth

Many of us have heard that handling a baby bird or bird egg will cause the parent birds to reject it.

Most birds have a very poor sense of smell, so they are unable to notice human scent on baby birds (even a skunk’s spray doesn’t seem to bother many types of birds). In most cases, even if the nest is destroyed by wind or other means, you could create a new one and put all the nestlings back in it and the parents wouldn’t care that their baby birds were in a different nest when they come back; so long as the new nest near where the old one was so they can find it.

Hoopoe

Ducks and Hoopoe will often poop on their own eggs with particularly smelly discharge to discourage predators from eating them.

Muscles and Fat

Muscles and fats are made up of very different types of cells that have completely different functions.  Skeletal muscles get larger when a person exercises. The muscles get larger, with more filaments being developed within the cells to accommodate the more challenging demand on them.

After a person quits exercising, the muscle cells do not magically turn into fat cells. They just shrink.  This allows the body to conserve energy when a person’s daily activities don’t require as much muscle mass.

The myth that muscles turn to fat when a person stops exercising probably stems from the fact that people who body build or otherwise exercise regularly and quit, tend to put on weight.

It all comes down to caloric intake. People who exercise regularly tend eat more food and when they stop exercising their body loses the need for the calories. These people may not reduce their food intake quickly enough to compensate for their reduced caloric needs.

Four Popular Myths Debunked

You lose most of your body heat through your head. A military study many years ago tested the loss of temperature in soldiers when exposed to very cold temperatures. They found rapid heat loss in the head. The results did not mention that they were fully clothed except for their heads. Without clothes on you lose about 10% of your body heat through your head.

You should drink at least eight glasses of water a day. In 1945 a government agency said that the human body required about 8 glasses of fluid a day. That includes fluid from all foods and drinks. Over time fluid was converted to water and hence the myth. However, water is filling and having a glass before meals does cut down on food consumption.

Eating turkey makes you sleepy because it contains tryptophan. Chicken and ground beef contain about the same amount of tryptophan as turkey does, while pork and cheese actually contain more. Turkey gets the bad rap because it is usually consumed during holidays with much other food and drink. Large heavy meals slow blood flow which can cause drowsiness.

Eating at night makes you fat. This one is just simple math. It doesn’t matter what time of day you eat. As long as you eat only the total calories that you burn each day, you will not gain weight. If you eat fewer calories than you burn, you will lose weight, and if you eat more calories, you will gain.

Medical Myth

Contrary to the myth, fingernails and hair do not continue to grow after death. What does happen is that the cuticles and skin shrink after death, making it appear as if the nails and hair were lengthening.
