Science myths and health misconceptions | Documentary


We’ve all heard that a glass of wine a day is healthy or that spinach is a good source of iron. But what is true and what is a myth?



There are many misconceptions about what is healthy and what is unhealthy. Insight is a constant process: what was accepted as true yesterday could be scientifically refuted today. But how do myths become embedded, even in the scientific community? Why can’t we simply replace old insights with new ones? Everything from methodological errors to manipulation can play a role. New myths aren’t just created in spite of science, but sometimes even with its help. One example: detoxing is a very popular myth at the moment. Removing toxins from the body is based on an understanding of medicine dating back to the early 20th Century. But modern medical experts say this notion of a build-up of toxins is nonsense. So why is it so hard to debunk the detox myth when it has no scientific basis? Dr. Lilian Krist, an epidemiologist at the Charité Hospital in Berlin says: “People want to believe in something. For many, these diet hypes and lifestyle trends have become a substitute religion.” New studies often throw up more questions than answers and more room for wrong interpretations – or even deliberately false conclusions. Once wrong information has become embedded in our brains, it’s difficult to get rid of again. Cognitive psychologist Ullrich Ecker has discovered that established myths people have believed in for generations are incredibly resilient. There’s even a boomerang effect: the more we try to destroy a myth, the more people believe in it.

  1. Part of the reason for resistance is science is often wrong. That doesn't mean we should throw out all science, but we must resist the more modern urge to NOT question science. If the science is sound it will stand up to scrutiny. One example I use is we were told over and over how unhealthy butter is by science and that we should use margarine instead. Turns out, years later, that the trans fats in margarine were much more unhealthy than if you just consumed butter.

  2. It is better to believe in myths that arise from science than from superstitions like mythologies. This shows that people at least care about knowledge, science and logic. People are ready to change if new and updated or corrected information comes to the fore. This is a great attitude. Mythologies like worshiping hand made idols, trees and animals and believing that these things have divine powers are far more dangerous than scientific myths.

  3. Leafy green vegetables are good for health and it's not about iron content. By calorie, they have a high percentage of plant protein, for example. They also have lots of vitamins and minerals, and probably also other healing components.

  4. Thank you for this documentary. I will however disagree about the contested myth that those children raised in an intellectual and intelligent parental education – with great music – do have a better chance of becoming more intelligent as their brain has been stimulated at an early age, resulting in children wanting to know and learn more.

  5. The diet thing is stupid because she just lied for profit to prove that the media lies? She really loses all credibility as a journalist when puts out information as truth knowing that she is lying and falsely making up facts…

  6. Of course our body can remove toxins… UNDER NORMAL circumstances, but if you eat toxic (processed or GMOs) food almost every day, the capacity of the body to clean itself becomes insufficient, and you NEED to do something radical to regain your health again, hence detox treatments.

  7. Actually the low iron content in spinach has to do with mineral depletion in soil………………….. in 1914 the iron content in spinach was 64 mg compared to 2.7 in 1994. And ALL detoxing is a myth..seriously?? This video and the medical professionals quoted in it disappoint me. This documentary is the epitome of misinformation. Thanks for creating even more confusion and disease! 👍

  8. Airlines don't use microwave oven so cell phone use in very low probability just by very very very small power compare to microwave oven but…..maybe.

  9. glutamate 100% definitely causes migraines … Glutamate is the primary excitatory neurotransmitter in your brain …. and unfortunately eating too much of it will definitely result in migraines or even seizures as it is passed unchanged through digestion into your bloodstream and across the "blood brain barrier".

    If you eat a heaping spoonful of the stuff the least of your worries will be the initial headache.

    … and no it's not an allergy, or some sort of issue specific to certain people "sensitive" to MSG.

    A heaping spoonful of MSG to your brain is like a giant shot of insulin would be to your metabolism … that is in large quantities it's certainly a poison.

  10. People are being tricked,…!!! We only listen to the things we want to hear. I LOVE THIS DOCUMENTARY. Because it shows facts I talked about while cooking online. Like me now, I did not want to hear that a glass wine daily in not healthy, only because alcohol makes me feel good.
