After a busy morning, lunch can feel like just the pick-me-up you need-but sometimes the meal that you thought would energize you is the very thing that makes you want to nap at your desk.

Feeling tired after lunch, or post-meals in general, is known as postprandial somnolence—or, colloquially, the food coma.

Part of this phenomenon is due to basic physiology (生理学): When humans eat, most of our blood goes to the digestive organs to process the food, said Sandra Arévalo, director of community health and wellness at Montefiore Nyack Hospital in New York state.

The tendency to get tired after eating isn’t inherently suggestive of something amiss (出错的). But there can be additional factors that worsen this natural response, making getting through the rest of the workday or any activities feel like a slog. Here’s what to watch out for and how to make adjustments.

When it comes to why you feel overly tired after eating, a common cause is consuming meals that are heavy in terms of quantity or quality. Not eating breakfast can lead to overindulging later in the day if excessive (过度的) hunger makes controlling your appetite difficult, Arévalo said.

Sometimes, however, the makeup of certain foods can contribute to tiredness. Fats are the hardest nutrient to digest because their molecules are much larger than those of protein or carbs, said Julie Stefanski, a spokesperson for the Academy of Nutrition and Dietetics. If you had a meal high in fat—such as fried foods or pizza—that could make you feel tired. Meals high in added sugar or refined or highly processed carbohydrates can have the same effect.

The fiber in so-called whole foods like corns slows the absorption of sugar into the body, which means they don’t cause blood sugar or insulin spikes and instead give you more stable, lasting energy, said Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic.

“A five-minute walk or something helps to improve circulation and alertness (机敏), as well,” Arévalo said.

A.Blood is bad for the digestive organs.

文章大意:本文是一篇说明文。食品安全问题是全世界的共同问题,世界上不同区域的人们以不同方式准备食物的。文章介绍了世界卫生组织发布的关于食品安全的五个原则。

【推荐2】Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way.     1    .

Keys 1: Keep clean

The first key tells about the importance of washing. —Before touching food while they are preparing food, and any time after they go to the toilet, people should wash their hands often.     2    . Keeping everything clean helps people to avoid micro-organisms.

Keys 2: Separate raw and cooked

People should separate raw, or uncooked food from foods that are already cooked and foods that will not be cooked.     3    , chicken, and fish in containers, or in separate areas. Raw foods should not touch prepared foods.

Keys 3:     4    

People should cook eggs and meat, like birds, seafood, and animals, especially carefully. These foods may carry more micro-organisms than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

Keys 4: Keep food at safe temperatures.

    5    , they should keep the leftover (吃剩的食物) in a refrigerator below 5℃ and shouldn’t store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms. They cannot grow so quickly in a very hot or very cold environment.

Keys 5: Use safe water and raw materials

People should use safe water and choose fresh foods. Damaged or old food may develop harmful chemicals as it gets older.

A.When people are finished with eating
B.Eat cooked food immediately, while it is still hot
C.They call these rules the “Five Keys to Safer Food”
D.People should wash all surfaces and equipment used for preparing food
E.Cook completely
F.People should also protect cooking areas and food from insects and animals
G.People should store raw meat

文章大意:这是一篇说明文,文章主要讲的是研究发现长时间闻垃圾食品的气味会降低消费者的购买欲望。

【推荐3】It’s one of the ultimate tests of willpower: you’ve been wandering around the market for hours and you’re tired and hungry. Then you catch a smell of something fragrant (香的) and delicious, probably fried and almost certainly fattening. Junk food companies are well aware that the smell of their product sets off a desire in your brain and that you’ll pay for that later. It is a response that has been researched, and you’d better believe your favorite fast-food chains have marketing teams that are using that research to their advantage.

Let’s take a closer look at this process. Have you ever noticed that whatever indulgent food (放纵型食品) catches your attention tends to be most appealing just after you first smell it? A couple of minutes later you are standing in line, and it isn’t quite as appealing as it was just moments ago, but now you’ve invested time, so you trust your first feeling to treat yourself.

But a recent statement says that this is actually the right moment to walk away. Dipayan Biswas, a marketing professor, found there is a direct connection between how long a person is exposed to indulgent food smells and choosing healthier foods. “The results of a series of experiments show that extended exposure of more than two minutes to junk food smells leads to fewer purchases of unhealthy foods compared with no smell or a non-junk-food-related smell,” reads the summary of his study.

What appears to be going on here is that the brain doesn’t necessarily distinguish between a pleasurable smell and a pleasant taste. “Extended exposure to an indulgent food smell brings pleasure in the mind, which in turn reduces the desire for actual consumption of indulgent foods,” he explains. So next time you feel you don’t have the willpower to resist cookies, smell all that sweetness for just a minute or two. To your brain it’s the same as actually eating cookies, and the purchase desire would decrease.

1. What can we learn about junk food smells from the first paragraph?
A.They hardly affect people’s food choices.
B.They can make a difference in marketing.
C.They are unlikely to fool wise customers.
D.They finally decrease people’s purchase desire.
2. What does the second paragraph basically serve as?
A.An example.B.An argument.
C.A comparison.D.A comment.
3. Which statement will Biswas probably agree with?
A.The influence of food smells changes over time.
B.The senses of taste and smell are closely linked.
C.The behavior of smelling food doesn’t equal eating it.
D.The brain can’t tell where sensory pleasure is from.
4. What is the best title for the text?
A.Train your brain to resist junk food
B.Smells of junk food can keep you off it
C.Watch out for tricky marketing tools
D.Food addiction is never about willpower
