不要再数羊了：十种助你熟睡的食物

Nonfat popcorn
脱脂爆米花

The carbohydrates in nonfat popcorn help bring the amino acid tryptophan into your brain, where it's used to make a sleep-inducing neurotransmitter called serotonin. Since eating a heavy meal within two hours of bedtime can keep you awake, low-calorie popcorn (just 93 calories in three cups popped) is a great late-night snack. Choose plain, fat-free popcorn and jazz it up with some curry powder.
脱脂爆米花中含有的碳水化合物可以将色氨酸带入闹钟，合成一种称为血清素的神经递质，能够帮助睡眠。由于在睡前两个小时以内过量饮食会让人清醒，所以低卡路里的爆米花（三份爆米花仅含有93卡路里）是最好的深夜零食。选择普通的脱脂爆米花，再混一些咖喱粉让它更有风味。
