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.

          The Best Way to Create a Vision for the Life You Want

          The Best Way to Create a Vision for the Life You Want

          Creating a vision for your life might seem like a frivolous, fantastical waste of time, but it’s not: creating a compelling vision of the life you want is actually one of the most effective strategies for achieving the life of your dreams. Perhaps the best way to look at the concept of a life vision is as a compass to help guide you to take the best actions and make the right choices that help propel you toward your best life.

          your vision of where or who you want to be is the greatest asset you have

            Why You Need a Vision

            Experts and life success stories support the idea that with a vision in mind, you are more likely to succeed far beyond what you could otherwise achieve without a clear vision. Think of crafting your life vision as mapping a path to your personal and professional dreams. Life satisfaction and personal happiness are within reach. The harsh reality is that if you don’t develop your own vision, you’ll allow other people and circumstances to direct the course of your life.

            How to Create Your Life Vision

            Don’t expect a clear and well-defined vision overnight—envisioning your life and determining the course you will follow requires time, and reflection. You need to cultivate vision and perspective, and you also need to apply logic and planning for the practical application of your vision. Your best vision blossoms from your dreams, hopes, and aspirations. It will resonate with your values and ideals, and will generate energy and enthusiasm to help strengthen your commitment to explore the possibilities of your life.

            What Do You Want?

            The question sounds deceptively simple, but it’s often the most difficult to answer. Allowing yourself to explore your deepest desires can be very frightening. You may also not think you have the time to consider something as fanciful as what you want out of life, but it’s important to remind yourself that a life of fulfillment does not usually happen by chance, but by design.

            It’s helpful to ask some thought-provoking questions to help you discover the possibilities of what you want out of life. Consider every aspect of your life, personal and professional, tangible and intangible. Contemplate all the important areas, family and friends, career and success, health and quality of life, spiritual connection and personal growth, and don’t forget about fun and enjoyment.

            Advertising

            Some tips to guide you:

            • Remember to ask why you want certain things
            • Think about what you want, not on what you don’t want.
            • Give yourself permission to dream.
            • Be creative. Consider ideas that you never thought possible.
            • Focus on your wishes, not what others expect of you.

            Some questions to start your exploration:

            • What really matters to you in life? Not what should matter, what does matter.
            • What would you like to have more of in your life?
            • Set aside money for a moment; what do you want in your career?
            • What are your secret passions and dreams?
            • What would bring more joy and happiness into your life?
            • What do you want your relationships to be like?
            • What qualities would you like to develop?
            • What are your values? What issues do you care about?
            • What are your talents? What’s special about you?
            • What would you most like to accomplish?
            • What would legacy would you like to leave behind?

            It may be helpful to write your thoughts down in a journal or creative vision board if you’re the creative type. Add your own questions, and ask others what they want out of life. Relax and make this exercise fun. You may want to set your answers aside for a while and come back to them later to see if any have changed or if you have anything to add.

            What Would Your Best Life Look Like?

            Describe your ideal life in detail. Allow yourself to dream and imagine, and create a vivid picture. If you can’t visualize a picture, focus on how your best life would feel. If you find it difficult to envision your life 20 or 30 years from now, start with five years—even a few years into the future will give you a place to start. What you see may surprise you. Set aside preconceived notions. This is your chance to dream and fantasize.

            A few prompts to get you started:

            • What will you have accomplished already?
            • How will you feel about yourself?
            • What kind of people are in your life? How do you feel about them?
            • What does your ideal day look like?
            • Where are you? Where do you live? Think specifics, what city, state, or country, type of community, house or an apartment, style and atmosphere.
            • What would you be doing?
            • Are you with another person, a group of people, or are you by yourself?
            • How are you dressed?
            • What’s your state of mind? Happy or sad? Contented or frustrated?
            • What does your physical body look like? How do you feel about that?
            • Does your best life make you smile and make your heart sing? If it doesn’t, dig deeper, dream bigger.

            It’s important to focus on the result, or at least a way-point in your life. Don’t think about the process for getting there yet—that’s the next stepGive yourself permission to revisit this vision every day, even if only for a few minutes. Keep your vision alive and in the front of your mind.

            Plan Backwards

            It may sound counter-intuitive to plan backwards rather than forwards, but when you’re planning your life from the end result, it’s often more useful to consider the last step and work your way back to the first. This is actually a valuable and practical strategy for making your vision a reality.

            • What’s the last thing that would’ve had to happen to achieve your best life?
            • What’s the most important choice you would’ve had to make?
            • What would you have needed to learn along the way?
            • What important actions would you have had to take?
            • What beliefs would you have needed to change?
            • What habits or behaviors would you have had to cultivate?
            • What type of support would you have had to enlist?
            • How long will it have taken you to realize your best life?
            • What steps or milestones would you have needed to reach along the way?

            Now it’s time to think about your first step, and the next step after that. Ponder the gap between where you are now and where you want to be in the future. It may seem impossible, but it’s quite achievable if you take it step-by-step.

            It’s important to revisit this vision from time to time. Don’t be surprised if your answers to the questions, your technicolor vision, and the resulting plans change. That can actually be a very good thing; as you change in unforeseeable ways, the best life you envision will change as well. For now, it’s important to use the process, create your vision, and take the first step towards making that vision a reality.
