How Sugar Affects the Brain
Dr. Nicole Avena explains how sugar affects the brain, and what happens in the body when you take a bite of sugary food in this illuminating TED-Ed lecture animated by STK Films.
When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine — an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.
