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.

          11 Hidden Benefits of Using Oil Diffusers

          11 Hidden Benefits of Using Oil Diffusers

          Affordable, relaxing, and healthy, oil diffusers are gaining popularity with people everywhere due to their extensive benefits. Oil diffusers work through the simple process of oil diffusion, which uses heat to turn oil into a vapor that is then spread around a living space. Diffused oil can have several relaxation and health-related benefits, including safe scent-dispersion, mosquito and mold defense, stress relief, and more!

          Read on for 11 hidden benefits of using oil diffusers.

          1. Safe Scents That Make Sense

          Unlike candles or air fresheners, oil diffusers release cleansing molecules into your air that work to purify it, not overload it with unhealthy chemicals. Electronic diffusers also do not pose the fire risk that candles do. Plus, they contain the added feature of interchangeability, which means you change oil types for different scents and health benefits.

          2. Stress Relief

          Several lab studies have confirmed that diffusing essential oils like lavender have been shown to reduce stress and help relieve anxiety in medical patients. Preliminary studies have also shown that oil diffusers can help alleviate symptoms of depression.

          3. Improved Sleep

          Diffused oil has relaxing properties that can help people of all ages fall asleep quicker and sleep more soundly. Electronic diffusers not only have the option to mix and match different oil blends (Try a lavender, Bulgarian rose, and Roman chamomile blend to help with insomnia), they also run at a gentle hum that helps relax an agitated mind. Many also come with an auto shut-off feature to help conserve oils once you have fallen asleep.

          4. Appetite Control

          Much like gum, oil diffusers can help stimulate the senses in a way that works to curb appetite. New research has shown that diffused peppermint oil can help curb appetite by inducing a satiety response within the body. Diffused peppermint oil has also been shown to increase energy.

          5. Bacteria and Mold Killing

          When essential oils are diffused in the air, they break down free radicals that contribute to the growth of harmful bacteria. Eucalyptus, thyme, and tea tree oils are especially good for this purpose. Diffused oil is also highly effective when it comes to combating fungal yeast threats, as the oil help makes the air inhospitable for yeasts such as mold. Pine and red thyme essential oils are best for combating mold.

          6. Decongestion and Mucus Control

          Ever tried Vick’s Vapo-Rub? Its decongesting powers come from active ingredients made from the eucalyptus tree. In principle, oil diffusers work the same way as Vapo-Rub, except they diffuse their decongesting vapor all around the room, not just on your chest or neck. Oil diffusers have been known to cure pneumonia in lab mice.

          7. Mosquito Repellant

          Nobody likes mosquitoes — but when the trade-off means using repellants full of DEET, a toxic chemical that can be especially harmful to children, mosquito control can often seem like a lose-lose. However, scientists have shown that oil diffusers can be used as a safe and highly effective mosquito repellant. Studies have shown that a diffused oil mixture containing clove essential oil and lemongrass essential oil repelled one type of Zika-carrying mosquito, the Aedes aegypti mosquito, at a rate of 100%.

          8. Pain Relief

          While applying oils directly to areas of your body may be the most effective way to alleviate pain, diffusing essential oils can also be an effective means of pain relief. When we inhale healthy essential oils, they enter our blood stream and can help internally relieve persistent pain from headaches, overworked muscles, and sore joints.

          9. The New Anti-Viral

          Research into the anti-viral effects of oil diffusion is now just gaining steam. A recent study showed that star anise essential oil was proven in medical experiments to destroy the herpes simplex virus in contained areas at a rate of 99%. Another study showed the popular DoTerra oil blend OnGuard to have highly-effective influenza-combating powers.

          10. Improved Cognitive Function

          Diffusing essential oils has also been shown to improve cognitive function. Many essential oils have adaptogenic qualities, which can work twofold in soothing us when we’re stressed, and giving our bodies a pick-me-up when we’re feeling down or sluggish. By working to level out an imbalanced mood, diffused oils also help us to focus. There are also several essential oils which have been shown to help balance the body’s hormones. With prolonged use, these oils can work to repair the underlying causes responsible for hindering cognitive function.

          11. Money Saving

          With ten clear benefits of oil diffusers already outlined, there is one more that should now be obvious: using an oil diffuser will help you to save money. As an anti-viral, bug repelling, and stress-relief solution rolled into one safe product, an oil diffuser used with the proper oils will save you money on products you might otherwise be buying to help cure those pesky headaches or get your kids to fall asleep on time. If you’re wondering just how affordable oil diffusers can be, check the buyer’s guide to the best oil diffusers — you’ll be sure to find one that fits your budget!
