Did last night’s dinner make you drool with anticipation¹? Did lunch have you licking your chops? According to research by teams from Thailand and Sweden, enjoying your food increases the nourishment² your body receives from it.
昨天的晚餐有没有让你垂涎三尺、充满期待？你的午餐是否让你意犹未尽？一项来自泰国和瑞典的研究小组的研究显示，尽情享用食物会增加机体对营养物质的吸收。

The Experiment
实验

Imagine a bowl of Thai vegetables and rice in coconut³ milk, seasoned with hot chili⁴ paste. Sound scrumptious? Or too spicy⁵ for your palate? The researchers served this dish to Thai women accustomed to such fare, then measured how much iron they absorbed.
准备一碗用非常辣的辣椒酱调味的泰式蔬菜米饭椰子汁。听起来很可口吧？或者对于你的口味来说太辣了？研究人员向已经适应了这种口味的泰国女性提供这道菜，然后测试她们吸收了多少铁。

Next, the researchers served the same meal to Swedish women accustomed to less spice. Guess what happened? The Swedish women absorbed significantly less iron than their Thai counterparts.
然后，研究人员向不太能吃辣的瑞典女性提供了同一道菜。猜猜发生了什么？相对泰国女性而言，这些瑞典女性吸收的铁明显少了很多。

Going further, the researchers served the Thai women the same ingredients, processed into an unappetizing, goopy puree. This time, the Thai women absorbed 70% less iron than they had before.
更进一步地，研究人员向泰国女性提供了一种相同成分的，但是制作成毫无吸引力的，泥糊状的浓汤。这次，泰国女性吸收的铁仅为之前的30%。

How Can This Be?
这是怎么回事？

The researchers believe the answer’s in the brain. Before you eat a bite, there’s a brain phase of digestive secretion⁶. Seeing, smelling, or just anticipating a good meal prompts the brain to send messages to glands⁷ along the digestive tract⁸. “Hey you guys!
研究人员认为答案在于大脑。当我们吃一口食物时，大脑里有一个消化分泌阶段。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。“嗨，伙计们，美食就要来啦！”

Yummy morsels⁹ coming!” These happy thoughts prompt secretion of saliva¹⁰, gastric¹¹ juices and enzymes¹² for digestion¹³. In particular, acidic gastric juices are key to iron absorption. Without the acid, the body absorbs little iron.
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。特别要说的是，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 gut¹⁴ to absorb the most nutrients¹⁵. So there’s scientific evidence for something we’ve suspected all along-an appealing, leisurely¹⁶ meal is a lot more nutritious¹⁷ than unappetizing grub!
但当你放松下来并且享用食物时，大脑会促使你的肠道吸收最大化的营养。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要有营养得多。
