How Does Sugar Affect Your Brain And Nervous System?

Your central nervous system (including your brain and spinal cord) is your master system controlling all cells, tissues and organs in your body. Your Nervous System can be effected in many different ways by different factors.

The health of your spine can have an impact on your nervous system which is one of the things we check at Chiropractic Central.

Also, our nutrition can play a huge role in the health of your nervous system. Sugar is one of the biggest culprits that can have a negative impact.   The more we know about it, the more we can change our behaviours to take our health to the next level.


Here are the top three ways that sugar affects your brain:

Constantly gives you intense cravings

Sugar is addictive. Eating something sweet activates feel-good hormones such as dopamine to be released. While a craving for chocolate once in a while is good, too much of this can result in a vicious addiction.


“Over-activating this reward system kick-starts a series of unfortunate events — loss of control, craving, and increased tolerance to sugar,” neuroscientist Nicole Avena explained in a TED-Ed video.


Research has shown that obese children light up differently when they taste sugar, activating the “food reward” element of their brain. This motivates children to continue eating in order to feel good. The study, published online in International Journal of Obesity reveals that some children have “brain circuitries that predispose them to crave more sugar throughout life.”


Additionally, the first author Kerri Boutelle reveals, “The take-home message is that obese children, compared to healthy weight children, have enhanced responses in their brain to sugar.” This results in children developing a life-long addiction to sugar.

Impairs memory and learning skills

Too much sugar leaves us feeling fatigued, tired and irritated. A recent study also revealed that a high-fructose diet could impair our memory and learning skills.


“Insulin is important in the body for controlling blood sugar, but it may play a different role in the brain, where insulin appears to disturb memory and learning,” he said. “Our study shows that a high-fructose diet harms the brain as well as the body. This is something new,” said Gomez-Pinilla, member of UCLA’s Brain Research Institute and Brain Injury Research Center.

It may contribute to depression and anxiety

Sugar crash is a term coined to explain the intense consumption of sugar leading to high sugar levels only to suddenly plummet and crash. This sudden crash in our blood sugar levels leads to low mood, feeling anxious and stressed. A study at Emory University School of Medicine revealed that a high-sugar diet leads to depression and anxiety-like behaviour, with teenagers being the most susceptible.
