When we consume sugar, it triggers a release of dopamine in our brains. Dopamine is a neurotransmitter that plays a significant role in our pleasure and reward system. This is why we often feel a rush of happiness or satisfaction after eating something sweet. However, this isn’t necessarily a good thing.
Over time, our brains can become desensitized to the dopamine rush, requiring more sugar to achieve the same level of pleasure. This can lead to cravings and a cycle of sugar addiction.

A study published in the journal Neurology found that high sugar diets could lead to poor memory and reduced brain volume, particularly in areas associated with memory.
