Scientists Discover Why You Should Stop Double-Dipping When Dining With Others

Scientists Discover Why You Should Stop Double-Dipping When Dining With Others

Knock it off already. You think people have noticed the double dipping? They do. And you need to stop. I’m not just saying that because your uptight relative has a huge problem with it. I get it, it’s fun to watch them squirm over this. There are scientific reasons why you need to stop as well as social ones. I have outlined the below. You are welcome.

Who Studied This?

Undergraduates at Clemson University studied double dipping.

How Were The Experiments Conducted?

Bitten crackers and unbitten crackers were studied by students. They measured the amount of bacteria could potentially transfer from the crackers by dipping into a cup of water.

They found “about 1,000 more bacteria per milliliter of water when crackers were bitten before dipping than solutions where unbitten crackers were dipped.”

It seems like what Mom said was right: germs are everywhere.

A second experiment tested bitten vs. unbitten in water with ph levels typical of food dips. The more acidic solutions were tested after 2 hours and they found that the bacteria lowered from the initial reading immediately after the bite.

Next different “dips” were tested. Salsa, chocolate, and cheese dips (all different ph levels and thickness.) They tested bacteria in the dips after bitten crackers were dipped and after unbitten crackers were dipped. Additionally they tested hours later to see how the colonies of bacteria faired after time had gone by.

Results

When single dipping there was no detectable amount of bacteria present.

Once double dipping took place there was bacteria and here is how it looked on the different dips:

Salsa had five times more bacteria (1000 bacteria/ml of dip) compared to chocolate and cheese dips (150-200 bacteria/ml of dip.)

Two hours later the salsa dropped to the same numbers of the chocolate and cheese dips. The acid in salsa helps to kill of bacteria over time.

The original results of more bacteria in salsa is thought to be related to the thickness. The salsa is not as thick as the chocolate and cheese counterparts. This means more dip (salsa) is touching the cracker and falling back in the bowl. As it falls back into the bowl it holds on for dear life to the bacteria that had reached out from the double dipper’s mouth. “Please pull us up too”, says the salsa as it careens back into the bow. “We can’t do it says,” the bacteria. And then the salsa says, “if we are going down you are coming down with us”. And they do in fact bring some with them. Thus polluting the salsa with the bacteria from double dipper.

How Worrisome Is This?

Well, it’s worrisome like shaking hands with a person that sneezed or coughed on their hand. Some calculated risks are taken when living in society and you are going to run into bacteria. By all means don’t skip the party in fear. In the same token if you see a person over at the salsa double dipping – don’t run towards them to get slopping seconds. You don’t know what dormant bacteria they might have.

Also, hey double dippers – when you live in polite society you also should maybe try to protect your fellow humans by not double dipping. If you must dip more put some on a plate and dip that way. After all I want you to have a good time. Just stay away from my salsa. You wouldn’t like me when I don’t have salsa.

How to Improve Memory and Boost Your Brainpower

How to Improve Memory and Boost Your Brainpower

Have you ever noticed that some people are able to effortlessly remember even the most mundane details and quickly comprehend new things? Well, you can too!

To unlock the full potential of your brain, you need to keep it active and acute. Wasting time on your couch watching mindless television shows or scrolling through facebook is not going to help.

Besides getting out flashcards, what can you do to help remember things better and learn new things more quickly? Check out these 10 effective ways on how to improve memory:

1. Exercise and Get Your Body Moving

Exercising doesn’t just exercise the body, it also helps to exercise your brain. Obesity and the myriad of diseases that eventually set in as a result of being overweight can cause serious harm to the brain.

Furthermore, without regular exercise, plaque starts to build up in your arteries, and your blood vessels begin to lose the ability to effectively pump blood. Plaque buildup leads to heart attacks and it also reduces the amount of oxygen and nutrients that your blood carries to your brain. When the nutrients don’t make it there, the brain’s ability to function is compromised.

To prevent this from happening, make sure you get moving every day. Even if it’s just a brisk walk, it’ll help you maintain and increase your mental acuity. Brisk walking, swimming and dancing are all excellent activities. Take a look at these 5 Ways to Find Time for Exercise.

2. Eliminate Stressors and Seek Help If You’re Depressed

Anything that causes you major stress, like anger or anxiety, will in time begin to eat away the parts of your brain that are responsible for memory. Amongst the most brain-damaging stressors is depression, which is actually often misdiagnosed a a memory problem since one of its primary symptoms is the inability to concentrate.

If you can’t concentrate, then you might feel like you are constantly forgetting things. Depression increases the levels of cortisol in your bloodstream which elevates the cortisol levels in the brain. Doctors have found that increased cortisol diminishes certain areas of the brain, especially the hippocampus which is where short-term memories are stored.

Prolonged depression can thus destroy your brain’s ability to remember anything new. Seek professional help to combat your depression – your brain will thank you.

3. Get a Good Night’s Sleep and Take Naps

Getting a consistent 7 to 8 hours of sleep each night will increase your memory. During sleep, the brain firms up memories of recently acquired information.

Getting enough sleep will help you get through the full spectrum of nocturnal cycles that are essential to optimal brain and body functioning during the waking hours. Taking a nap throughout the day, especially after learning something new, can also help you to retain those memories as well as recharge your brain and keep it sharper longer.

4. Feed Your Brain

Fifty to sixty percent of the brain’s overall weight is pure fat, which is used to insulate its billions of nerve cells. The better insulated a cell is, the faster it can send messages and the quicker you will be thinking.

This is precisely why parents are advised to feed their young children whole milk and to restrict dieting – their brains’ need fat to grow and work properly. Skimping on fats can be devastating even to the adult brain.

Thus, eating foods that contain a healthy mix of fats is vital for long-term memory. Some excellent food choices include fish (especially anchovies, mackerel and wild salmon) and dark leafy green vegetables. Here’re more brain food choices: 12 Foods that Can Improve Your Brain Power

Deep-fried foods obviously contain fat but their lack of nutritional value is not going to help your brain or your body, so think healthy foods and fats.

5. Eat Breakfast and Make Sure It Includes an Egg

According to Larry McCleary, M.D., author of  The Brain Trust Program, an egg is the ideal breakfast. Eggs contain B vitamins which help nerve cells to burn glucose, antioxidants that protect neurons against damage; and omega-3 fatty acids that keep nerve cells firing at optimal speed.

Other foods to add to your breakfast include fruits, veggies and lean proteins. Avoid trans fats and high fructose corn syrup. Trans fats diminish the brain cells’ ability to communicate with each other and HFCS can actually shrink the brain by damaging cells.

Having a healthy breakfast in the morning has been shown to improve performance throughout the day. If you’re too busy to have a healthy breakfast, this maybe just right for you: 33 Quick And Healthy Breakfasts For Busy Mornings

6. Write it Down

If there’s something you want to remember, writing it down can help.

It may sound like a no-brainer, but do you really know why? Writing it down creates oxygenated blood flow to areas of your brain that a responsible for your memories and literally exercises those parts of it. Here’s How Writing Things Down Can Change Your Life.

You can start a journal, write yourself emails or even start keeping a blog – all of these activities will help to improve your capacity to remember and memorize information.

7. Listen to Music

Research shows that certain types of music are very helpful in recalling memories. Information that is learned while listening to a particular song or collection can often be recalled by thinking of the song or “playing” it mentally. Songs and music can serve as cues for pulling up particular memories.

8. Visual Concepts

In order to remember things, many people need to visualize the information they are studying.

Pay attention to photographers, charts and other graphics that might appear in your textbook; or if you’re not studying a book, try to pull up a mental image of what it is you are trying to remember. It might also help to draw your own charts or figures, or utilize colors and highlighters to group related ideas in your notes.

Here, you can learn How to Become a Person Who Can Visualize Results.

9. Teach Someone Else

Reading material out loud has been shown to significantly improve memory of the material. Expanding further upon this idea is the fact that psychologists and educators have found that by having students teach new concepts to others, it helps to enhance understanding and recall.

Teach new concepts and information to a friend or study partner, and you’ll find you remember the information a lot better.

10. Do Crossword Puzzles, Read or Play Cards

Studies have shown that doing crossword puzzles, read or play cards on a daily basis not only keep your brain active but also help to delay memory loss, especially in those who develop dementia.

So pick up the daily newspaper and work on that crossword puzzle, read a book or enjoy a game of solitaire.

Pick one to two of these tips first and start applying them to your everyday life. Very soon you’ll find yourself having better memories and a clearer head!
