时差N小时 大快朵颐能增加营养吸收?(下)

The researchers believe the answer’s in the brain. Before you eat a bite, there’s a brain phase of digestive secretion¹.

研究人员认为答案在于大脑。当人们吃食物时，大脑中有一个消化分泌阶段。

Seeing, smelling, or just anticipating a good meal prompts the brain to send messages to glands² along the digestive tract³.

视觉，嗅觉，或者仅仅是对美食的期待，会促使大脑传递信号到消化道的腺体。

“Hey you guys! Yummy morsels⁴ coming!” These happy thoughts prompt secretion of saliva⁵, gastric⁶ juices and enzymes⁷ for digestion⁸.

“嗨，伙计们，美食快来啦！”这些愉悦的思想促进唾液，胃液和消化酶的分泌来帮助消化。

In particular, acidic gastric juices are key to iron absorption. Without the acid, the body absorbs little iron.

需要专门强调的是，酸性的胃液是铁吸收的关键物质。没有酸，机体几乎不能吸收铁。

When you’re relaxed and enjoying your food, your brain primes your gut⁹ to absorb the most nutrients¹⁰.

但人们放松下来享用食物时，大脑会促使肠道最大程度地吸收营养。

So there’s scientific evidence for something we’ve suspected all along-an appealing, leisurely¹¹ meal is a lot more nutritious¹² than unappetizing grub!

因此，该实验结果也成了支持我们猜想的论据，即一餐令人食指大动，逍遥自在的美食远比毫无吸引力的食物有营养。
