002 TED-ED 糖如何影响你的大脑

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. [Directed by STK Films, narrated by Michelle Snow, music by Michael Dow].当你食用含糖多的食物时, 你的味蕾、肠道和大脑都会敏锐地注意到它。这种对大脑犒赏系统的激活与身体对酒精或者尼古丁的上瘾并没有什么两样——糖的过多摄入会使多巴胺分泌量激增，并且会使你渴求更多。Nicole Avena解释了为什么人们应当有节制地享用糖果与甜食。
