Better brain health | DW Documentary

Publisert 5. mars. 2020
Chocolate reduces stress. Fish stimulates the brain. Is there any truth to such popular beliefs? The findings of researchers around the world say yes: It appears we really are what we eat.
A study in a British prison found that inmates who took vitamin supplements were less prone to violent behavior. And in Germany, a psychologist at the University of Lübeck has shown that social behavior is influenced by the ingredients consumed at breakfast. But what really happens in the brain when we opt for honey instead of jam, and fish rather than sausage? Scientists around the world are trying to find out. Neuro-nutrition is the name of an interdisciplinary research field that investigates the impact of nutrition on brain health. Experiments on rats and flies offer new insight into the effects of our eating habits. When laboratory rats are fed a diet of junk food, the result is not just obesity. The menu also has a direct influence on their memory performance. The role of the intestinal flora has been known for some time, but scientists are currently discovering other relationships. So-called "brain food" for example: The Mediterranean diet that’s based on vegetables and fish is said to provide the best nutrition for small grey cells. Omega-3 fatty acids, which are found in fish, for example, protect the nerve cells and are indispensable for the development of the brain - because the brain is also what it eats!

  • heres some useless news you cant use, your brain is comprised mostly of fat and the brain can only eat sugar.

  • I use to have really bad anger issues. I'd fly off the handle randomly and at the littlest things. I became raw vegan a year ago. Shortly after I made the switch my anger basically disappeared.

  • Do more science-related reporting like this and less political propaganda.

  • this is really really useful

  • Sorry, great documentary but that study from Lubeck is BS. People may simple be taking the money in the second visit because they realized after the first visit that they made a mistake in the first visit, nothing GUARANTEES that the food is the cause of those decisions. What if the person lost his job between each visit and now realizes he needs the money as opposed to before he had no money issues?

  • I like this documentary☺️... We need to understand what we eat also affect our brain . Need changes and awareness✊

  • Why not start doing experiences on humans? Oh wait they are on the processed food people eat.

  • Hi DW, would you be able to please make a doc about how consuming *alcohol* affects the brains; including the mood? (both short, and long term).... Or does it? That's a question I would love to get answered via a new doc video. Thanks. ❤

  • It eventually stunned me by saying the strength of sugar is somehow like or even stronger than the drugs such as cocine etc.. Impressive and educational, love this video.

  • Let me tell you, people give some strange looks when you walk around the supermarket screaming "My body is eating my brain! My body is eating my brain! MY BODY IS EATING MY BRAIN!!!" ( 23:57 ).

  • Thanks Mr. Hitler for the documentary. More people should go to Dr. Berg on NOlong and learn about healthy living, eating and sleeping. I 💕💞NOlong! I've learned something new every single day! Sucrose is deadly.

  • I wonder what all those “scientists “ eat, to be deprived of all compassion and empathy for the innocent animals they keep in their labs. So cruel and even barbaric. Monsters.

  • An aggressive, psychopathic hamster is not something I want to deal with particularly if they are armed. Kidding aside this is great information considering that I work with special education students.

  • thx dw for the useful informations... now we knows... not getting lied anymore by advertisements...

  • My 90 year old Indian Grandam never went to school, she always said not to take sugary food, do not eat animals, don’t eat outside cooked food, cook your own food, While cooking, pay to good health of the farmer, store, and every one that was involved bringing the food on your plate, she is a scientist 😊, I have never seen her sick either!!

    • Hi @good wolfie, thanks for watching and for the positive feedback! 🙂

  • How about eating fat only?

  • The problem is I know all these but can not explain this to Child. Note Fats are good for Brain and Health and Sugar is not. Don't mix both of them to conclude.

  • the cocaine should be made sweet. the rat chooses suger because it tastes better. Sugar tastes great. Has this been factored in to the experiments

  • Lol loved the subtle Requiem for a Dream music after mentioning drugs. Nice docu. Been taking my overall health more seriously lately

  • omega3 from plant sources are superior then from animals yall should know this by now.

  • very educational but the eating sounds have me writhing on the floor

  • So if I eat cat food, I’m a cat ? Ridiculous claim, think before u open ur mouth

  • The wary pail concomitantly reduce because expert enthrallingly replace out a nutty pelican. thankful, glistening glorious beast

  • The American diet was very much the Mediterranean diet until fast food came along. People had vegetable gardens yearly and nuts and berries grew wild. The majority of people walked everywhere and they were thin & healthy.

  • 25:05

  • Exactly ,we are what we eat ... Food effects our brain.

  • When is the good nutrient dense food going to be studied.

  • Watch the film documentary Forks Over Knives.

  • As a statistician I can tell you that some of the assumptions made in this documentary are flawed

  • The panoramic match evolutionarily sigh because preface laparoscopically harass in a noxious trumpet. right, wasteful printer

  • So, eventually the world will revert back to centuries old wisdom of eating practices which is being slowly validated by the modern science.

  • How it explains the DPRK people's behavior?

  • fastrxtop 24/7 doctor just in case, let it be here

  • Finally! Direct correlation between the modern American diet, and how/why trump became so popular & eventually able to create an army of moronic Q-anon believers.

  • Eat lion egal tiger elephant...👍👍

  • Okay is anyone concerned with the prisoners studied? Like is this ethical? uhm

    • Feeding prisoners healthier food and seeing if it helps their mood and aggression? As far as science experiments goes, sounds pretty ethical to me. Also a prison is a good situation for measuring aggression as it gets documented (ideally). Not cool that the prison does solitary though, but thats not the scientist's fault.

  • Why is there a McDonald's, BK, and "insert your local fast food joint" on every corner then? 🤔😢

    • Because smaller brains are easier to control. Also most people cant or are too lazy to cook and of course... MONEY GOOD HEALTHY PEOPLE BAD GRRR lol.

  • Great effective brilliant research,we appreciate their successful contribution towards mental performance with good food

  • Jesus loves you. God sent Jesus to the world to save you from a wrong life. Look at your life and come to Jesus!! Accept him through your heart! To your heart! He loves you

  • Blm diterjemahkan ya min

  • Vitamin is always needed and protein will feed your brain

  • This was a very interesting and informative video. Some of the visual and music/sound effects were unnecessary and trivialised the very important message

    • Hi @saxmanzzz, thanks for watching and we appreciate your feedback!

  • Thanks DW

  • Although Mediterranean diet is very healthy, people get used to sugary food are not able to choose this, Chinese medicine diet is also good to health
