8.蔬菜与水果

People say that vegetables are good for you. But this is not the case with some vegetables, especially when you’re trying to have a good night’s sleep.

人们都说蔬菜和水果非常健康，没错!但如果你正需要好睡眠，那么有些蔬菜就应该避免在睡前吃!

Cauliflower and broccoli make nice examples for this. These vegetables contain tryptophan, the same amino acid present in proteins that regulates sleep. Tryptophan does this by assisting in the production of serotonin, a hormone that induces sleepiness. Unfortunately, cauliflower and broccoli are also high in roughage. The roughage makes them difficult to digest. If you eat these vegetables too close to sleeping time, you will still be able to get some shut eye. But your body will take time in digesting them, preventing it from relaxing completely.

花椰菜和西兰花就是很好的例子，因为它们含有色氨酸。有助睡眠的蛋白质里也含有同样的氨基酸，色氨酸妨碍睡眠是因为它们会助长血清素的生成，这种激素会影响睡眠。另外，花椰菜和西兰花还是高粗纤维蔬菜，粗纤维难以消化，如果睡前吃的话你还是能睡着，但你的身体还醒着，努力消化着它们。这样你就没法完全休息到啦!
