Piled high with ice cream is your mouth watering are you craving dessert
Why what happens in the brain
That makes sugary food so hard to resist
Sugar is a general term
Used to describe a class of molecules called carbhydroes
And it's found in a wide variety of food and drink
Just check the labels on sweet products
You buy glucose fruittose suitrose
Meltose
Lactose
Dexros and stch are all forms of sugar sower high fruit to us corn syrup fruit
Juice raw sugar and honey and sugar isn't just in candies and desserts
It's also added to cato sauce yoga dried fruit
Flaoured waters or grrenola vars
Since sugar is everywhere
It's important to understand how would affects the brain
What happens
When sugar hits your tongue sueating a little bit of sugar make you cve more 嗯的
You take a bite of serial the sugar
It contains activate the sweet taste receptors part of the taste buzds on ttongue
These receptors send a signal up to the brain stem
And from there
It folks off into many areas of the four brain
One of which is the cerebral cortex different sections of the cerebral cortex process different tastes
Bitter
Suulty
Umomi
And in our case sweet
From here
The signal activates the brains reward system
This reward system is a series of electrical and chemical pathways
Across several different regions of the brain
It's a complicated network
But it helps answer a single subconscious question
Should i do that again
That warm fuzzy feeling you get
When you taste gramma's chocolate cake one of your reward system saying um yes
And it's not just activated by food
Socializing
Sexual behavior and drugs for just a few examples of things and experiences
That also activate the reward system
But overactivating this reward system kick starts a series of unfortunate events
Loss of control
Craving and increased tolerance to sugar
Let's get back to our bite of cereal
It travels down into your stomach and eventually into your gut
And guess what there are sugar receptors here too they're not taste budds
But they do send signals telling your brain that you're full
Or that your body should produce more insulent to deal with the extra sugar
You're eating
The major currency of our reward system is dopamine an important chemical or neurrotranspitter
There are many dopamine receptors in the four brain
But there are not evenly distributed certain areas contained dense clusters of receptors
These dodoamine ine t spots ts a part of our reward systems
Drugs like alcohol nigagaine or heroin send dopamine into overdrive
Leading some people to constantly seek that high in other words to be addicted
Suggalso causes dopamine to be released
Though not is violently as drugs and sugar is rare
Among dopamine inducing foods brobrogley for example has no effect
Which probably explains why it so hard to get kids to eat their veggies
Speaking of healthy foods
Let's say you're hungry and decide to eat a balanced meal you do and dopamine levels spike in the reward system hot spots
But if you eat that same dish many days in a row
Dopamine levels will spike less and less eventually levelling out
That's because when it comes to food the brain evolved to pay special attention to new or different tastes
That's two reasons
First to detect food that's gone bad
And second because the more variety we have in our diet
The more likely we are to get all the new trents
We need to keep that variety we need to be able to recognize a new food
And more importantly we need to want to keep eating new foods
And that's why the dopamine levels off
When a food becomes boring now back to that meal
What happens
If in place of the healthy balanced dish you eat sugar
Rich food instead
If you rarely eat sugar or don't need much at a time
The effect is similar to that of the balanced meal
But if you eat too much
The dopamine response does not level out in other words
Eating lots of sugar will continue to feel rewarding
In this way
Sugar behaves a little bit like a drug
It's one reason
People seem to be hooked on sugary foods
So think back to all those different kinds of sugar
But every one is unique
But every time
Any sugar is consumed
It kick starts a domino affect in the brain
That sparks of rewarding feeling it's much too often
And things can is overvever so have over consumption of sugar can have addictive effects on the brain
But a wedge of cake once in a while won't hurt you
