Do you sometimes find you want to eat chocolate or ice cream very much? Do you then make it but feel guilty about it later?
The next time this happens to you, think back if you have had enough sleep over the last 3-5 days. Many adults and even teens have noticed that they crave "midnight snacks" when working or watching TV late.
New research shows that lack of sleep could lead us to have an increased appetite (食欲)- especially for the unhealthy kind.
Recently, researchers at the University of Chicago carried out a study that clearly shows that a lack of sleep actually changes our brain chemistry! Studies were done on two control groups over four days. Both groups had their food and sleep strictly controlled. All of them received three meals. The only difference was that one group was allowed to sleep for 7.5 hours while the other group slept for a little more than four hours.
During the following visit, their sleep patterns were exchanged. After the last night of the session, the volunteers were offered as much food as they wanted to eat. Researchers noticed that in both sessions, people who sleep less ate on an average 300 calories more than those who had slept more. This was much more calories than what their bodies would need to make up for the three fewer hours of sleep.
What Is Going On?
The researchers then analyzed the chemicals (化学成分) in the blood of the people in the study. What they noticed was surprising. High levels of ghrelin (a chemical that makes us hungry) and lower levels of leptin (the chemical that tells the brain that it is satisfied) were found in the people with less sleep.
Even more surprising was that this group had higher levels of endocannabinoids - the same chemical that is caused by drugs such as cannabis (大麻). The endocannabinoid system causes a craving for sugar and fatty foods and leads to overeating even when the body is not hungry. This study suggests that sleep changes help produce chemicals in the body that are similar to taking drugs!
Furthermore, researchers noticed that food cravings continued for a long period of time, well after the lack of sleep. This increases the risk of over-eating for longer periods, leading to obesity (肥胖).
Your body needs 7-8 hours of sleep each night. So, the next time you reach for a bag of chips or a slice of decadent cake, think of the amount of sleep you have had recently!

A Bite of China
Are you an eating-lover? Do you want to eat every delicious food in the world? Then do you watch the popular program A Bite of China? It’s a TV program on Chinese delicious food which has been produced by CCTV. Is there any holiday that isn’t celebrated with special festival food? Here are several traditional Chinese foods:
Noodles are a symbol of long life in Chinese culture. They are as much a part of Chinese birthday celebration as a birthday cake with its candles lit in many western countries. Since noodles mean long life, it is considered very unlucky to cut it off.
Although westerners sometimes may be very sorry to see fish lying on the plate, in China a whole fish is a symbol of richness. In fact, at a party it is a tradition to serve the whole fish last, pointed towards the most valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come.
A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanuts or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan in Chinese history.

A.a magazine B.a newspaper
