Artificial sweeteners may be derailing your brain’s food-reward - TopicsExpress



          

Artificial sweeteners may be derailing your brain’s food-reward system. Eating real sugar releases dopamine into your brain’s reward center, which contributes to the delicious taste you experience. At the same time the hormone leptin, which regulates appetite, triggers a feeling of fullness and reduces the flow of dopamine to your brain. This balanced system keeps you from overeating because the more bites you take, the fuller you become and the less pleasurable the food. But regularly eating artificial sweeteners alters your brain’s reward system as the taste of sweetness stops being a reliable measure of caloric intake. While research is only beginning to uncover how this alteration impacts long-term health, it suggests that the key may be moderating intake of both real and fake sugar.
