Dr. Nicole Avena put together a short lesson for TED-Ed about how sugar affects the brain and why some people seem to be addicted to sweets. Similar to a drug, sugar activates the brain’s reward system, making people crave more. And similar to drug users, people who eat a lot of sugar can actually build up a tolerance to its effects, making them crave it even more. This lesson is especially important in a world in which even our water has added sugar.
