Sugar

Once our taste buds have experienced the taste of sugar, we are trapped. From that time on, all it takes is thinking about the taste and dopamine levels in the nucleus accumbens rise. The brain uses 50% of the body's available sugar energy. This sugar energy is taken directly from the blood because the brain has no effective way to store sugar. The proper balance of sugar is necessary for the manufacture of neurotransmitters and brain functions like attention, cognition, and mood stability. If there is too much sugar in the brain it ages more quickly, accelerating memory loss and dementia.
