2 Health Myths You Are Taught in School that Are Wrong

2 Health Myths You Are Taught in School that Are Wrong

In high school, and even beyond that, we are taught to believe a lot of things that aren’t true. Most of the time it is not on purpose, but these health myths are still harmful.

Myth 1: Alcohol kills brain cells

Sure, if you physically pour 100% alcohol onto a brain, it’s not going to react very well. When you are drinking alcohol though, this is not the case (read this book). The original research into this was done as follows:

  1. Take dead alcoholics and regular people
  2. Check brain cell density in both
  3. Alcoholics had lower density in their brain
  4. Conclusion: alcohol kills brain cells

Why it this wrong?

Well, it’s called a ‘confounding variable’. Basically, there was another factor at play. Specifically here:

  • Alcoholics tended to be of lower education
  • Alcoholics tended to have worse nutrition

A brain without good nutrition and no stimulation in the form of education is obviously not going to be the same as one of a person who does have those things.

After this was pointed out, the data was analyzed taking into account these factors. Guess what? No difference.

It’s still harmful, though.

But there should be a clear distinction between alcohol use and alcohol abuse. Alcohol can increase risk of specific cancers in some people, and in high dosages, it is detrimental to the liver (and yes, the brain).

When enjoyed responsibly, though, alcohol actually appears to increase lifespan. And for some cancers, risk actually seems to be lower if you drink small amounts.

On the note of addiction, alcohol has a relatively high addiction potential, though it’s lower than tobacco:

Drug-harm-chart

    If you have trouble believing this graph, don’t worry, you are not the first. It’s from the paper “Development of a rational scale to assess the harm of drugs of potential misuse,” and entirely accurate.

    How much is fine?

    For men, drinking 2 standardized glasses a day is the max. For women, 1. Note that you can’t save up! If you don’t drink during the week, that doesn’t mean you can have ten drinks on Saturday and still call it healthy.

    Myth 2: Eating cholesterol increases your blood cholesterol

    This one bothers me even more than the first. It bothered me so much I spent months doing cholesterol research to find out why on earth we still believe this. It all started because someone used epidemiological research to make headlines.

    Epidemiological what?!

    Cholesterol-Intake-Map

      It’s simpler than it sounds. Epidemiological research is something like this:

      1. The average Swedish citizen has white skin
      2. The average South African citizen has black skin
      3. Sweden gets little sun
      4. South Africa gets a lot of sun
      5. Sun probably makes your skin darker

      Makes sense right? There is only one big problem: you can never prove anything with epidemiological research. Look at this example to see why:

      1. The average Dutch citizen has white skin
      2. The average South African citizen has black skin
      3. The Dutch eat a lot of cheese
      4. South Africans eat little cheese
      5. Cheese probably makes you white

      See the problem there? Just because two things coincide, it doesn’t mean they are in any way connected.

      Your eat 300mg, you make 1000mg

      This is basic biology, taught to every doctor: the average person eats 300mg of cholesterol a day. The average liver produces 1000mg a day.

      Read that again. Your own body produces three times more cholesterol than you eat. Do you really think that that 300mg is the problem?

      Advertising

      If you eat more than 300mg cholesterol, your liver senses this and produces less.

      The trouble starts if the liver can’t keep up.

      LDL and HDL for dummies

      The cholesterol in your food is not the cholesterol in tour blood. In your food it is a simple substance, in your blood it is balled up into a complex of cholesterol and proteins.

      ldl-and-hdl

        Simplified:

        • LDL is a fluffy cholesterol ball that carries cholesterol from the liver to the body
        • HDL is a dense ball that carries cholesterol from the body back to the liver

        What matters is not so much how much cholesterol you have, but whether your LDL (giver) is in balance with your HDL (cleaner).

        Advertising

        So what does cause high cholesterol?

        Mostly food. Specifically sugars and other fastly absorbed food. Take a look at this collection of graphs:

        Cholesterol-low-carb-vs-low-fat
          • The red line is a low fat diet
          • The yellow line a mediterranean diet
          • The purple line a low-carb diet

          The purple line basically wins on every measurement type, while a low fat diet loses.

          To keep cholesterol under control you should basically read up in low glycemic index foods.

          20 Creative Ways To Say Thank You

          20 Creative Ways To Say Thank You

          Saying, “Thank you,” can be difficult to do. Some things just demand a little something extra because of the magnitude of the favor or the depth of appreciation involved. But what can you do to say thank you in a meaningful way? Sometimes you have to get a little more creative than just firing off an email. Here are 20 creative ways to say thank you that your friends and family will remember and cherish!

          1. Make a gift bag.

          A unique, homemade gift bag with a custom label or a note is a simple but heartfelt way to show your appreciation for the wonderful things your friends or family have done for you.

          2. Give a toast.

          Many people fear public speaking more than death, giving this particular thank-you a little extra meaning. Composing a sincere, eloquent toast and delivering it is a nice way to show appreciation that truly comes from the heart.

          3. Write a poem.

          “Roses are red, violets are blue…” Uh, you could write that...but why not put a little extra zing in it? Find out what their favorite kind of poetry is: haiku, free verse, iambic pentameter, and so on. (Google them if you don’t know what they are.) Then write one that expresses why they deserve your thanks…and why you’re glad to give it!

          4. Create your own labels.

          There are a number of websites that offer custom gift labels. Find one that fits your personality and that of your friends and create a personalized thank-you label!

          5. Give a gift card.

          Sometimes choosing what to give a friend can be tough. A gift card is a good way to get around this problem. As always, be sure to include a personalized note or card thanking the recipient for their friendship and help.

          6. Send a letter.

          Snail-mail is a largely lost art form. Don’t worry about how long the letter is, though. What really matters here is that you took the time to put pen to paper and express your feelings sincerely and honestly!

          7. Use social media to send a special message.

          If someone’s done something you think the whole world should know about, why not put out a social media blast? Use your blog, your Facebook, your Google+ account, and your Twitter to spread the word about why this person’s someone your friends will want to know too!

          8. Make your own digital greeting card.

          While an email isn’t always the best way to go when saying thank you, a digital greeting card that you put time and effort into creating can really brighten someone’s day! Make the card reflect the recipient’s personality and compose a short message of thanks for their generosity.

          9. Make a YouTube video.

          Sometimes, actually hearing someone say, “Thank you,” can make all the difference. Why not take it a step further and create a special video of thanks for your friends, family, and those special people who helped make your day so important…or who helped you through that rough time?

          10. Deliver cookies or candies.

          Making something yourself is a fun and delightful way to say thank you to someone. Create a sampling of baked goods or homemade candies and decorate them with a simple message, or make them so they form letters! (Think Valentine’s candies, only situationally appropriate.) Attach a thank-you note or label and surprise those special people with the gift of your time and creativity.

          11. Make surprise gifts for guests.

          There’s no need to wait until “later” to send a thank-you message. Why not do it at the time? Create little gift packets or bags for your guests with surprises inside. This is a great way to say thanks to the people who attended your event, and make sure they won’t want to miss the next one!

          12. Put together a flower basket.

          Whether you prefer fresh or artificial flowers, assembling a flower basket with a thank-you note is an excellent way to brighten someone’s day and show you appreciate them.

          13. Take a picture.

          Sometimes capturing the moment is the best way to put a smile on someone’s face. Have someone take a picture of you receiving that special gift or opening that surprise package and send the giver a copy with a quick but sincere note to say thanks!

          14. Repay their generosity by paying it forward.

          The best gifts come from the heart, and the best way to repay a gift is to pay it forward. If your friend has a special cause they care about or something they believe in passionately, why not make a donation in their name or volunteer some of your time to the cause? This will mean more than any number of cookies, candies, or thank-you notes because you’re taking your friend’s love and spreading it around to others.

          15. Do something special for them.

          Take them out to dinner. (See “make a toast.”) Give them that movie they’ve been wanting forever. Cook them dinner and give them a present when they arrive. Any of these are good options for showing someone you really appreciate them and how grateful you are to have them in your life.

          16. Reciprocate their help.

          Everyone needs help sometime. Whether it’s holding their hand through a particularly traumatic incident or helping them replace the alternator in their car, being there when they need it shows you remember what they did for you and how much it meant. It also shows that you’re willing to be just as good a friend to them as they were to you!

          17. Be there for them.

          Not every thank-you gesture has to be a grand public spectacle. Sometimes just giving them a place to come hang out when they’re lonely or showing up to offer them a sympathetic shoulder means the world to a person.

          18. Listen to them.

          Listening is almost as lost an art as the handwritten letter. When your friend or family member needs to talk, listen to them. Ask questions when appropriate, but just letting them know you’re there and paying attention to them to the exclusion of all else for a little while is a great way to say thank you for the times they listened to you.

          19. Say it in another language…or two…

          A simple thank you is great…but why not spice it up a little? Instead of just saying, “Thank you,” write or make a video of you telling them thank you in different languages. Some examples might be, “Gracias! Merci! Danke schoen! Spasibo! Mahalo!” and any other ways or languages you can think of. (The ones listed above are Spanish, French, German, Russian, and Hawaiian, in case you were wondering.) If you want to really get tricky about it, say a short phrase in each language that conveys why you’re thanking them!

          20. Show them some love.

          A simple touch, a hug, or helping out when they need it without being asked may be the most powerful gratitude message you can send. Offer to take the dogs for a walk, sit for the kids for a few hours, or run to the grocery store so they don’t have to. The little things are often the most important and meaningful. That doesn’t mean you shouldn’t still send a note, but sometimes your simple presence and willingness to help is all that really matters.
