Check out our Patreon page: https://www.patreon.com/teded View full lesson: http://ed.ted.com/lessons/how-sugar-affects-the-brain-nicole-avena When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation. Lesson by Nicole Avena, animation by STK Films.

thanks for meaningful video. Official dietary guidelines for eating sugar/carbs in humans is 0 grams per day - provided we eat enough essential fatty acids and protein. Go carnivore. Sugar is a poison. it causes diabetes, Alzheimer's and is highly associated with many other deadly illnesses - from cancer to heart disease. we often crave the the very substances we're most intolerant to.

Great explanation of sugar addiction. Bad advice to have a wedge of cake every once in a while, if you have food addiction.

I was born with extra senitice taste buds so basically if I eat 1 piece of suger it would feel like I ate 100 sweets or chocolate so I would feel sick so that's why I prefer more savoury and umami tastes also ESPECIALLY spicy (I love spicy food)

So, how can someone know what the body really needs at any moment? It would be a lot easier. The body lacks of this aliment and you eat it, and there'll be no mistakes such as overeating or eating the wrong food.

The idea is good but the animation is really distracting. It has many unnecessary elements. Why bubbles? The narration is also boring.

In my opinion the brain needs minor amounts of sugar to function properly. ...it's fairly easy to go without sugar.

I love brokkoli! Always did :) As my parents never forced me to eat it or anyone said things like „kids do not like brocolli“. Mum just cooked and served and it was up to us to eat. The only thing she would have been concerned was water. Kids are fine without a loads of food unless they drink enoguh water. I was a happy child in that case and now i am still getting overly excited when i see fresh veggies and fruits! I was off sugar for a while. Since i started working at a restaurant it happened that i ate it more and more thru the food there. Now i am at the climax that i always hated. This out of control sugar craving monster. Thank you for that video! A great motivation to go off sugar again :)

#1 solution to global warming is to ADD 1,000 solar panels to each school. That will give the solar schools a source of energy & money from selling solar, at $0.49 kwh , onto the grid. Youtube: paul8kangas #1 issue is climate meltdown. Stop doing what you are doing & start spending one hour each day adding solar to school. Surplus solar will help the schools raise teachers pay, so that teachers make as much as fire fighters and police. We need to educate the next generation to help stop global warming. Ban mandatory vaccines for anyone under age 18. One in 30 boys & men are now autistic, caused by the metals in vaccines. Paul Kangas for SF Board of Education Nov. 2018. This heat wave is only getting started. In 2019 there will be more heat, more hurricanes, more fires, more insane crimes, Lancaster, Ca., requires all homes be 100% solar powered.
But does sugar affect the brain on the way you think ? For example when the exam time comes you should it less sugary thinks and more healthier so you can study better ? No?

I watched this video because even though I am not overly addicted to sweats I want to know what it feels like to reduce sugar intake. I'll comment a month from this date.

Dopamine isn't exactly the "reward neurotransmitter" dopamine is also secreted when people go to get a rotten tooth drilled and capped by a dentist. A universally undesirable experience. It's far more the "reinforcing neurotransmitter" in response to either desirable or undesirable events.

John Spurlock (5 months ago)
Well I think the reason people eat a lot of sugary food because the food that we have second can't it's like eating paper but when you eat sugar you get energy when you're tired if you eat three candy bars you can go to work now if food you might just have a carrot
