(2017·福州质量检测)Who hasn't found themselves reaching for the closest food available when they're tired and stressed? More and more research is proving that this isn't all in our mind. Some foods really do lead to a change in our moods (心情).
Carbohydrate (碳水化合物) for calm
This is how some people medicate themselves with food — by reaching for cookies or pasta(意大利面食) whenever they're upset.
Unfortunately, it doesn't always work.
You must eat a meal consisting of 100% carbohydrate, on an empty stomach, to obtain the serotonin (血清素) increase so that you have a good mood.
To get the wishedfor effect, you must not eat anything for four hours and then eat at least 30 grams of straight carbohydrate. Dry cereal (谷类食品), a piece of bread with jam, or a potato should do_the_trick.
Protein (蛋白质) for power
Of course, sometimes we don't need to be calm and sleepy.Sometimes we need a great deal of mental concentration, so this is when it's important to mix protein and carbohydrate. The protein will prevent the tryptophan(色氨酸) from flooding your brain,and the rise in serotonin won't occur.
Why dessert makes us happy
Fat and sugar cause the brain to let go endorphins (内啡肽),which send pleasure signals throughout the body. This would be fine, except humans are not particularly good at stopping at one cookie or cake.
