摘要
葡萄糖能抑制大脑细胞分泌使我们清醒的促食素,但氨基酸可以解除这种抑制。克里斯蒂·尼科尔森的报告中说。不久前的一个下午,我又犯困了。充满倦意、行动迟缓的我抓了一块巧克力塞进嘴里。但也许我应该吃一些蛋白或是一块牛排。因为一项最近的研究发现,能使小白鼠亢奋的是蛋白质而非糖份。作为脑细胞的一种,阿里新细胞分泌一种刺激让我们充满活力,并给身体指示燃烧卡路里。
Glucose can block brain cell secretion of orexin,which keeps us alert.But amino acids can stop thatblock.Christie Nicholson reports.The other afternoon I hit a classic mid-afternoon slump.Sleepy and sluggish,I grabbed for a bit of chocolate.But I probably should have had egg whites or maybe a piece of steak.Because a recent study in mice has found that it's protein,not sugar,that provides the perk.Brain cells called orexin cells secrete a stimulant that makes us energetic and tells the body to burn calories.If the cells'activity decreases,narcolepsy or sudden sleepiness,is the result.
