How can processed sugar affect our children's learning and mental health?

A high intake of sugar can lead to at least eight unintended responses and consequences, including lack of focus, mood swings, memory issues, increased stress, changes in personality, addiction, childhood obesity, and weakened immune system.

 

Processed sugar is addicting!

Sugar Origins and Processing Insights

  • The majority of sugar is derived from sugar cane or white sugar beets, with sugar cane naturally containing beneficial components like soluble fiber, antioxidant phenols, vitamins, and minerals, and exhibiting a low glycemic index.
  • Sugar cane primarily consists of sucrose, offering more nutritional value in its raw form compared to sugar beets.
  • However, throughout the processing stages of sugar cane and sugar beets, all nutritional benefits are removed, including fibers, vitamins, enzymes, and antioxidants, resulting in 99.99% pure white sugar.
  • Once all the nutrients are stripped away during processing, sugar essentially transforms into an addictive substance resembling a drug, although the sugar industry resists regulation due to its addictive nature.

 

Refined sugar is prevalent in processed foods, often without clear labeling of the added sugar content, making it challenging to avoid.

Refined sugar is not the same as sugar found in natural food sources.

When we eat processed sugar, the brain produces huge surges of dopamine. The brain reacts to a surge in sugar the same way it reacts to heroin and cocaine. Brain scientists agree this is because our bodies have adapted to choose foods that are high in calories.

The emotional lift processed sugar provides is short-lived. Post-spike crashes lead to sluggishness, lack of motivation, and lack of concentration because of the changes in our dopamine levels. Refined sugar interrupts and confuses certain neurotransmitters.

How does refined sugar affect dopamine?

Dopamine is a neurotransmitter in the brain. It communicates messages between nerve endings. In part of the brain, called the rewards center, dopamine receptors become active when exposed to an excitability toxin, such as cocaine and refined sugar. Watch the two minute video below for a visual explanation of the brain's reward system:

So how does refined sugar disrupt our brain?

Sugar or any drug, stimulates the dopamine receptors which produces a euphoric or exciting feeling. Neurons produce neurotransmitters over a cycle of time. When concentrated amounts of refined sugar are consumed, a huge rush of dopamine floods the brain. This depletes the neurons of the neurotransmitter which causes the high and low of the refined sugar rush. We develop one or more of the eight unintended consequences of ingesting refined sugar, and then we crave more to experience the euphoric or exciting feeling--the addition begins. When we are constantly consuming refined sugar, we are causing over stimulation of our dopamine receptors.  Over time, they eventually produce less and less dopamine at a time causing an increase in sugar cravings and harder swings from high to low.  We can see our balance has been disrupted.

The effect sugar has on dopamine and dopamine receptors make it addictive.  This is why it is so difficult to cut refined sugar out of our diets.  It is also extremely difficult to eat or buy processed foods without added sugar.  Pick up the labels and look for the number of “added sugars."
